the PCM-4890. Sections include: • Card specifications • Card layout and dimensions Chapter 1 General Information 1 CHAPTER Introduction The PCM-4890 is an enhanced, all-in-one single board 486 comput- er with an on-board Ethernet interface, local-bus SVGA controller. The PCM-4890 offers all the functions of an AT-compatible industrial computer on a single board, but it fits in the space of a 5¼" floppy drive (only 5.75" x 8"). For maximum performance, the PCM-4890 also supports 2nd level cache sizes from 128 KB to 512 KB (32 KB x 8, 64 KB x 8, or 128 KB x 8). On-board features include four serial ports (RS-232 and RS-232/ 422/485), one parallel port, an enhanced IDE hard-drive controller (for up to two drives), a floppy-drive controller and a keyboard/PS/ 2 mouse interface. The board's watchdog timer can automatically reset the system or generate an interrupt if it stops due to a program bug or EMI problem. The PCM-4890 also complies with the "Green Function" standard and supports three types of power saving features: Doze mode, Standby mode, and Suspend mode. All display and Ethernet configuration is done through software. A single Flash chip holds the system BIOS, VGA BIOS and the network boot ROM function. This minimizes the number of chips and eases configuration. You can change the display BIOS or install a boot ROM simply by programming the Flash chip. If you need any additional functions, you can add up to six industry-standard PC/104 expansion modules, or use ISA peripheral cards via the on-board ISA expansion slot. 2 PCM-4890 User's Manual Features • Accepts DX2/DX4 and 5x86 CPUs • Award Flash BIOS, Flat-panel configured by programming Flash chip • 2nd level cache: supports up to 512 KB cache memory • 32-bit VL-bus SVGA controller, display both CRT and LCD simulta- neously • 16-bit Ethernet interface, Novell NE2000 compatible • One ISA expansion slot • Built-in VL bus-master IDE controller supports two IDE devices (large hard disk, CD ROM, tape backup, etc.) • Supports both normal and EDO type DRAM from 1 to 64 MB • One enhanced multi-mode SPP/EPP/ECP parallel port.

A jumper is the simplest kind of electric switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To “close” a jumper you connect the pins with the clip. To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3. In this case you would connect either pins 1 and 2 or 2 and 3. 3 2 1 Open Closed Closed 2-3 The jumper settings are schematically depicted in this manual as follows: 1 2 3 Open Closed Closed 2-3 A pair of needle-nose pliers may be helpful when working with jumpers. If you have any doubts about the best hardware configuration for your application, contact your local distributor or sales representa- tive before you make any changes. Generally, you simply need a jumper to make most connections. Chapter 2 Installation 11 Safety precautions Warning! Always completely disconnect the power cord from your chassis whenever you are working on it. Do not make connections while the power is on because sensitive electronic components can be damaged by the sudden rush of power. Only experienced electronics personnel should open the PC chassis. Caution! Always ground yourself to remove any static charge before touching the CPU card. Modern electronic devices are very sensitive to static electric charges. Use a grounding wrist strap at all times. Place all electronic components on a static-dissipative surface or in a static-shielded bag when they are not in the chassis. Installing the CPU The PCM-4890 all-in-one CPU module supports most 486 CPUs. The system's performance depends on the CPU you choose. You can install or upgrade the CPU in the board's PGA socket by following the procedures outlined below. If your system has an existing CPU, you need to remove it before installing the new CPU. Removing a CPU 1. Disconnect power from the chassis, and unplug all connections to the CPU card. Then, remove the CPU card from the chassis by following the instructions in the user's manual for your chassis. 2. Lift the CPU out of the PGA socket. The old chip may be difficult to remove. You may find spray chip lubricant, designed for pin-grid-array (PGA) devices, and a chip puller helpful. These are available at electronics hobbyists' supply stores. 12 PCM-4890 User's Manual Installing a CPU To install the CPU, follow the instructions that came with it. If no documentation was provided, the general procedures for installing a CPU are outlined below: 1. Lubricate the pins on the CPU with lubricant for PGA devices. This makes the CPU slide in much easier and greatly reduces the chance of damaging the pins and other components. 2. Carefully align the CPU so that it is parallel to the socket. Make sure that the notch on the corner of the CPU matches the notch on the inside of the socket. 3. Gently push the CPU into the socket. There will probably be a small gap between the CPU and the socket even when it is fully seated. DO NOT USE EXCESSIVE FORCE! When you install a new CPU, you may have to adjust other settings on the board, such as CPU type, CPU clock, and PCI speed, to accommodate it. Make sure that the settings are correct for your CPU. Improper settings may damage the CPU. Chapter 2 Installation 13 CPU type select (J3, J4, J5, J7, J9, J10, J11) The following charts show jumper settings for their respective CPUs.

Access time should be 70 nsec. or less. Memory installs in two banks composed of one SIMM socket each. The banks are designated as Bank0 and Bank1. See the figure on page 10 for help identifying the banks. You must fill Bank0 first. If you fill both banks, the memory capacity of both SIMMs should be the same. Installing SIMMs NOTE: The modules can only fit into a socket one way. Their chips must face the CPU, and their gold pins must point down into the SIMM socket. The procedure for installing SIMMs appears below. Please follow these steps carefully. 1. Ensure that all power supplies to the system are switched Off. 2. Locate the board's memory banks, shown in the figure on page 9. 3. Install the SIMM cards. Install each SIMM so that its chips face away from the CPU and its gold pins point down into the SIMM socket. 4. Slip each SIMM into a socket at a 45 degree angle and carefully fit the bottom of the card against the connectors. 5. Gently push the SIMM into a perpendicular position until the clips on the ends of the SIMM sockets snap into place. 6. Check to ensure that each SIMM is correctly seated and all connector contacts touch. The SIMM should not move around in its socket. Chapter 2 Installation 17 IDE hard drive connector (CN9) The built-in Enhanced IDE (Integrated Device Electronics) control- ler supports up to two IDE devices, including CD-ROM drives, tape backup drives, a large hard disk drive and other IDE devices. It also supports faster data transfer rates and allows the IDE hard disk drive to exceed 528 MB. Connecting the hard drive Connecting drives is done in a daisy-chain fashion and requires one of two cables, depending on the drive size. 1.8" and 2.5" drives need a 1 x 44-pin to 2 x 44-pin flat-cable connector. 3.5" drives use a 1 x 44-pin to 2 x 40-pin connector. Wire number 1 on the cable is red or blue, and the other wires are gray. 1. Connect one end of the cable to CN9. Make sure that the red (or blue) wire corresponds to pin 1 on the connector, which is labeled on the board (on the right side). 2. Plug the other end of the cable to the Enhanced IDE hard drive, with pin 1 on the cable corresponding to pin 1 on the hard drive. (See your hard drive's documentation for the location of the connector.) Connect a second drive as described above. Unlike floppy drives, IDE hard drives can connect to either end of the cable. If you install two drives, you will need to set one as the master and one as the slave by using jumpers on the drives. If you install just one drive, set it as the master. 18 PCM-4890 User's Manual Floppy drive connector (CN15) You can attach up to two floppy disks to the PCM-4890's on-board controller. You can use any combination of 5¼" (360 KB and 1.2 MB) and/or 3½" (720 KB, 1.44 MB, and 2.88 MB) drives. A 34-pin daisy-chain drive connector cable is required for a dual- drive system. On one end of the cable is a 34-pin flat-cable connec- tor. On the other end are two sets of floppy disk drive connectors. Each set consists of a 34-pin flat-cable connector (usually used for 3½" drives) and a printed-circuit board connector (usually used for 5¼" drives). Connecting the floppy drive 1. Plug the 34-pin flat-cable connector into CN15. Make sure that the red wire corresponds to pin one on the connector. 2. Attach the appropriate connector on the other end of the cable to the floppy drive(s). You can use only one connector in the set. The set on the end (after the twist in the cable) connects to the A: drive. The set in the middle connects to the B: drive. 3. If you are connecting a 5¼" floppy drive, line up the slot in the printed circuit board with the blocked-off part of the cable connector. If you are connecting a 3½" floppy drive, you may have trouble determining which pin is pin number one. Look for a number printed on the circuit board indicating pin number one. Also, the connector on the floppy drive connector may have a slot. When the slot is up, pin number one should be on the right. Check the documentation that came with the drive for more information. If you desire, connect the B: drive to the connectors in the middle of the cable as described above. If you need to make your own cable, you can find the pin assign- ments for the card’s connector in Appendix C. Chapter 2 Installation 19 Parallel port connector (CN12) Normally the parallel port is used to connect the card to a printer. The PCM-4890 includes an on-board parallel port, accessed through CN12, a 26-pin flat-cable connector. You will need an adapter cable if you use a DB-25 connector. The cable has a 26-pin connector on one end and a DB-25 connector on the other. Parallel port IRQ The PCM-4890 supports one parallel port. The port is designated as LPT1 and can be disabled or changed to LPT2 or LPT3 in the system BIOS setup. Parallel port IRQ selection IRQ5 *IRQ7 J23 1 2 2 3 You can select ECP/EPP DMA channel by setting J15 and J16. ECP/EPP DMA channel *DMA1 DMA3 J6 J22 1 2 2 3 * default setting Keyboard and PS/2 connector (CN8) The PCM-4890 board provides a keyboard connector which supports both a keyboard and a PS/2 style mouse. In most cases, especially in embedded applications, a keyboard is not used. The standard PC/AT BIOS will report an error or fail during power-on self test (POST) after a reset if the keyboard is not present. The PCM-4890's BIOS standard setup menu allows you to select "All, But Keyboard" under the "Halt On" selection. This allows no- keyboard operation in embedded system applications without the system halting under POST (power-on-self-test). 20 PCM-4890 User's Manual Front panel connector (CN5) Next you may want to install external switches to monitor and control the PCM-4890. These features are completely optional — install them only if you need them. The front panel connector (CN5) is an 8-pin male, dual in-line header and provides connections for a speaker, hard disk access indicator and an input switch for reset- ting the card. Speaker The PCM-4890 can drive an 8 W speaker at 0.5 watts. Ensure that alternatives to this specification do not overload the card. LED interface The front panel LED indicator for hard disk access is an active low signal (24 mA sink rate). Reset switch If you install a reset switch, it should be a open single pole switch. Momentarily pressing the switch will activate a reset. The switch should be rated for 10 mA, 5 V. If you need to make your own cable, you can find the pin assign- ments for the card’s connector in Appendix C. Power connectors (CN7, CN10, CN3) Peripheral power connector, -5V, -12V (CN7) Supplies secondary power to devices that require -5 V and -12 V. Main power connector, +5V, +12V (CN10) Supplies main power to the PCM-4890 (+5 V) and devices that require +12 V. Fan power supply connector (CN3) Provides power supply to optional CPU cooling fan. Only present when +5 V and +12 V power is supplied to the board. Chapter 2 Installation 21 Serial ports (CN14) The PCM-4890 offers four serial ports: three RS-232 and one RS- 232/422/485. These ports let you connect to serial devices (a mouse, printers, etc.) or a communication network. COM1, COM3, COM4 RS-232 ports (CN14) The serial port connectors are mounted on the right hand side of the card. The 40-pin, dual-in-line, male header to the right of the card is the RS-232/422/485 port.

However if you wish to disable the port or change these parameters later you can do this in the system BIOS setup. The table below shows the settings for the PCM-4890's ports. PCM-4890 Serial port default settings Port Address Range Interrupt Default COM1 2E8~3F8 IRQ4 3F8 COM2 2E8~3F8 IRQ3 2F8 COM3 IRQ5/10 2EF COM4 IRQ5/10 2E8 VGA interface connections The PCM-4890's SVGA interface can drive conventional CRT displays and is capable of driving a wide range of flat panel displays, including electroluminescent (EL), gas plasma, passive LCD and active LCD displays. The card has two connectors to support these displays, one for standard CRT VGA monitors and one for flat panel displays. CRT display connector (CN1) CN1 is a 16-pin, dual-in-line header used for conventional CRT displays. A simple one-to-one adapter can be used to match CN1 to a standard 15-pin D-SUB connector commonly used for VGA. Pin assignments for CRT display connector CN1 are detailed in Appendix C. Flat panel display connector (CN2) CN2 consists of a 44-pin, dual-in-line header. Power supplies (+12 V, -12 V) present on CN2 depend the supply connected to the board. Ensure that both CN7 and CN10 are connected for ±12 V power supply. Chapter 2 Installation 23 The PCM-4890 provides a bias control signal on CN2 which can be used to control the LCD bias voltage. It is recommended that the LCD bias voltage not be applied to the panel until the logic supply voltage (+5 V) and panel video signals are stable. Under normal operation the control signal (ENAVEE) is active high. When the PCM-4890's power is applied, the control signal is low until just after the relevant flat panel signals are present. Configuration of the VGA interface is done completely via the software utility. You don't have to set any jumpers. Refer to Chapter 3 for software setup details. Refer to Chapter 3 for details on connecting the four standard LCD's: Sharp LM64183P, Toshiba LTM09C016, Sharp 64C142, and Planor EL Display. 24 PCM-4890 User's Manual Ethernet configuration The PCM-4890 is equipped with a high performance 16-bit Ethernet interface which is fully compliant with IEEE 802.3 10Mbps CSMA/ CD standards. It is supported by all major network operating systems and is 100% Novell NE-2000 compatible. Configuration of the Ethernet is very easy and can be done via the RSET8019.EXE program included on the utility disk. This program enables you to: view the current Ethernet configuration, to recon- figure the Ethernet interface (IRQ, I/O address, etc.), and to execute useful diagnostic functions. (See Chapter 3 for detailed informa- tion) The RSET8019.EXE program provides two ways to configure the Ethernet interface. Configuration can be done automatically when you choose PNP (plug and play) option; or, when you choose the Jumperless option, the following IRQ and I/O address settings are available. PCM-4890 Ethernet settings IRQ option I/O address range Jumperless 2, 3, 4, 5, 10, 200 - 300 EFH Configuration 11, 12, 15 Default Settings: IRQ = 3 ; I/O Address = 300H Note: 1. You can select an IRQ from the options shown above, but make sure your selection does not conflict with other I/O devices. 2. When Boot ROM is installed, the RSET8019.EXE program does not support PNP mode configuration. 10BASE-2/10BASE-5 AUI connector (CN11) 10BASE-2 and 10BASE-5 coax connections are made via an attachment unit interface or AUI (CN11). This consists of a 16-pin, dual-in-line male header. Chapter 2 Installation 25 10BASE-T connector (CN13) 10BASE-T connects to the PCM-4890 via an adapter cable to a 10- pin polarized header (CN13). For 10BASE-T RJ-45 operation, an adapter cable converting CN13 into a standard RJ-45 jack is required. Network boot The Network Boot feature can be utilized by incorporating the Boot ROM image files for the appropriate network operating system. The Boot ROM BIOS files are available from your supplier. They can be programmed into the BIOS, similar to the VGA BIOS file, using the AWDFLASH.EXE program detailed in Chapter 3. 26 PCM-4890 User's Manual Watchdog timer configuration An on-board watchdog timer reduces the chance of disruptions which EMP (electro-magnetic pulse) interference can cause. This is an invaluable protective device for standalone or unmanned applications. Setup involves two jumpers and running the control software (refer to Appendix A). Watchdog timer enable/disable You can enable or disable the watchdog timer by reading the I/O ports with your program. Read address 443 hex to enable and refresh the watchdog or address 043 to disable the watchdog. For information on programming the watchdog timer see Appendix A. Watchdog timer action (J19, J20) When the watchdog timer activates (CPU processing has come to a halt), it can reset the system or generate an interrupt on IRQ15. This can be set via two 2-pin jumpers (J19, J20) as shown below: Watchdog timer system reset/IRQ15 *System reset IRQ15 J19 * default setting Watchdog timer enable/disable Enable Disable J20 Chapter 2 Installation 27 28 PCM-4890 User's Manual 3 Software Configuration This chapter details the software configu- ration information. It shows you how to configure the card to match your applica- tion requirements. AWARD System BIOS is covered in Chapter 4. Sections include: • LCD display configuration • Connections for four standard LCDs • Ethernet interface configuration Chapter 3 Software Configuration 29 CHAPTER Introduction The PCM-4890 system BIOS and custom drivers are located in a 128 Kbyte, 32-pin (JEDEC spec.) Flash ROM device, designated U27. A single Flash chip holds the system BIOS, VGA BIOS, and network Boot ROM image. The display can be configured via software. This method minimizes the number of chips and eases configuration. You can change the display BIOS simply by reprogramming the Flash chip. Utility disk The PCM-4890 is supplied with a software utility disk. This disk contains the necessary file for setting up the VGA display and Ethernet controller. Directories and files on the disk are as follows: README.DOC COOKROM.EXE NET (Dir) RSET8019.EXE PG8019.EXE 8019.CFG DISPLAY (Dir) AWDFLASH.EXE 4890_SYS.BIN 4890_CRT.BIN 4890_TFT.BIN 4890_STN.BIN 4890_ST5.BIN 4890_MON.BIN 4890_EL.BIN CDROM.EXE COOKROM.EXE A program that converts application files into binary files (files with a .BIN extension). These are then written into the SSD Flash ROM devices. RSET8019.EXE This program enables you to view the current Ethernet configura- tion, reconfigure the Ethernet interface (medium type, etc.), and execute useful diagnostic functions. 30 PCM-4890 User’s Manual PG8019.EXE The PCM-4890 is initially setup at the factory using this program. When you receive your card, use RSET8019.EXE to configure for the working environment. If by chance the EEPROM is corrupted, the PG8019.EXE program allows you to reconfigure the card. 8019.CFG When you run PG8019.EXE, it will read the configuration parameters stored in this file. AWDFLASH.EXE This program allows you to write the VGA BIOS files to the BIOS Flash ROM. The VGA files all come ready formatted for the PCM-4890 with .BIN extensions. See README.DOC. These files support various CRT and flat panel displays. They are custom written and can be made available upon request. 4890_SYS.BIN This binary file contains the system BIOS. 4890_CRT.BIN Supports CRT only. 4890_TFT.BIN (default) Supports 640 x 480 color TFT (Sharp LQ9D011, Toshiba LTM09C015A/016). 4890_STN.BIN (1 MB VRAM) Supports 640 x 480 color STN DD 8/16-bit displays (Sharp LM64C142). 4890_ST5.BIN (512 KB VRAM) Supports 640 x 480 color STN DD 8/16-bit displays (Sharp LM64C142). NOTE: This BIOS does not support simultaneous CRT and flat panel display with 512 KB VRAM 4890_MON.BIN Supports 640 x 480 dual scan monochrome displays (Sharp LM64P8X/837). Chapter 3 Software Configuration 31 4890_EL.BIN Supports 640 x 480 EL displays (PLANAR EL640480 - A Series). CBROM.EXE This program allows you to combine your own VGA BIOS with system BIOS (4890_SYS.BIN). VGA display software configuration The PCM-4890’s on-board VGA interface supports a wide range of popular LCD, EL, gas plasma flat panel displays and traditional analog CRT monitors. The interface can drive CRT displays with resolutions up to 1024 x 768 in 256 colors. It is also capable of driving color panel displays with resolutions of 640 x 480 in 64K colors. The VGA interface is configured completely via the software utility, so you don’t have to set any jumpers. Configure the VGA display as follows: 1. Apply power to the PCM-4890 with a color TFT display attached. This is the default setting for the PCM-4890. Ensure that the AWDFLASH.EXE and *.BIN files are located in the working drive. NOTE: Ensure that you do not run AWDFLASH.EXE while your system is operating in EMM386 mode. 32 PCM-4890 User’s Manual 2. At the prompt, type AWDFLASH.EXE and press . The VGA configuration program will then display the following: VGA Setup screen 3. At the prompt, type in the BIN file which supports your display.

Chapter 4 Award BIOS Setup 39 CHAPTER System test and initialization These routines test and initialize board hardware. If the routines encounter an error in during the tests, you will either hear a few short beeps or see an error message on the screen. There are two kinds of errors: fatal and non-fatal. The system can usually continue the boot up sequence with non-fatal errors. Non-fatal error messages usually appear on the screen along with the following instructions: Press to RESUME Write down the message and press the F1 key to continue the bootup sequence. System configuration verification These routines check the current system configuration against the values stored in the card’s CMOS memory. If they don’t match, the program outputs an error message. You will then need to run the BIOS setup program to set the configuration information in memory. There are three situations in which you will need to change the CMOS settings: 1. You are starting your system for the first time 2. You have changed the hardware attached to your system 3. The CMOS memory has lost power and the configuration information has been erased. The PCM-4890’s CMOS memory has an integral lithium battery backup. The battery backup should last ten years in normal service, but when it finally runs down, you will need to replace the complete unit. 40 PCM-4890 User’s Manual AWARD BIOS setup R O M I S A B I O S ( 2 C 4 L 6 A K L ) C M O S S E T U P U T I L I T Y A W A R D S O F T W A R E , I N C .

Chapter 5 SVGA Setup 63 64 PCM-4890 User’s Manual A Programming the Watchdog Timer The PCM-4890 is equipped with a watchdog timer that resets the CPU or generates an interrupt if processing comes to a standstill for whatever reason. This feature ensures system reliability in industrial standalone, or unmanned, environments. Appendix A Programming the Watchdog Timer 65 APPENDIX Jumpers J19 and J20 control the watchdog settings. The default configuration of the timer is enabled with system reset. To enable the watchdog timer, you must write a program which reads I/O port address 443 (hex) at regular intervals. The first time your program reads the port, it enables the watchdog timer. After that, your program must read the port at time interval of less than 1.6 seconds, otherwise the watchdog timer will activate and reset the CPU or generate an interrupt on IRQ15. When you want to disable the watchdog timer, your program should read I/O port 043 (hex). If CPU processing comes to a standstill because of EMI or a software bug, your program's signals to I/O port address 443 to the timer will be interrupted. The timer will then automatically reset the CPU or invoke an IRQ, and data processing will continue normally. You must write your program so that it reads I/O port address 443 at an interval shorter than the timer's preset interval. The timer's intervals have a tolerance of ±30%, so you should program an instruction that will refresh the timer about every second. The following program shows how you might program the watchdog timer in BASIC: 10 REM Watchdog timer example program 20 X=INP (&H443) REM Enable and refresh the watchdog 30 GOSUB 1000 REM Task #1, takes 1 second to complete 40 X=INP (&H443) REM Refresh the watchdog 50 GOSUB 2000 REM Task #2, takes 1 second to complete 60 X=INP (&H043) REM Disable the watchdog 70 END 1000 REM Subroutine #1, takes 1 second to complete . . . 1070 RETURN 2000 REM Subroutine #2, takes 1 second to complete . . . 2090 RETURN 66 PCM-4890 User’s Manual B Installing PC/104 Modules This appendix gives instructions for installing PC/104 modules. Appendix B Installing PC/104 Modules 67 APPENDIX Installing PC/104 modules The PCM-4890's PC/104 connectors give you the flexibility to attach PC/104 expansion modules. These modules perform the functions of traditional plug-in expansion cards, but save space and valuable slots. Modules include: • PCM-3290 GPS Module • PCM-3810 Solid State Disk Module • PCM-3820 High Density Flash Disk Module • PCM-3110 PCMCIA Module • PCM-3111 Secondary PCMCIA Module • PCM-3610 Isolated RS-232 and RS-422/485 Module • PCM-3660 Ethernet Module • PCM-3718 30 KHz A/D Module • PCM-3724 48-Channel DIO Module • PCM-3640 4-Port RS-232 Module • PCM-3680 Dual Port CAN Module Installing these modules on the PCM-4890 is quick and simple. The following steps show how to mount the PC/104 modules: 1. Remove the PCM-4890 from your system paying particular attention to the safety instructions already mentioned above. 2. Make any jumper or link changes required to the CPU card now. Once the PC/104 module is mounted you may have difficulty in accessing these. 3. Normal PC/104 modules have male connectors and mount directly onto the main card. However, to ensure better bus matching, the connectors on the PCM-4890 and the PC/104 module are both female. For this reason, you may need to use the "male-male" adapter included with the PCM-4890 in order to properly connect your PC/104 module. (Refer to the diagram on the following page.) 4. Mount the PC/104 module onto the CPU card by pressing the module firmly but carefully onto the mounting connectors. 5. Secure the PC/104 module onto the CPU card using the four mounting spacers and srews. 68 PCM-4890 User's Manual PC/104 Mounting Support Female Module PC-104 Module Mainboard PC/104 Module Mounting Diagram 0.300 3.250 3.775 3.575 3.575 0.200 0.200 0 3.350 0.200 0 3.550 PC/104 module dimensions (inches ±5 %) Appendix B Installing PC/104 Modules 69 70 PCM-4890 User's Manual C Pin Assignments This appendix contains information of a detailed or specialized nature.
