The AR-B1542 are equipped with a programmable time-out period watchdog timer User can use the program to enable the watchdog timer. Once you have enabled the watchdog timer, the program should trigger it every time before it times out. If your program fails to trigger or disable this timer before it times out because of system hang, it will generate a reset signal to reset the system. The time-out period can be programmed to be 3 to 42 seconds. Enable (D7) Time Base Time Factor (D0-D2) Watchdog Register Counter and Write and Trigger Compartor Watchdog RESET LED Figure 4-1 Watchdog Block Diagram 4.3.1 Watchdog Timer Setting The watchdog timer is a circuit that may be used from your program software to detect crashes or hang-ups. Whenever the watchdog timer is enabled, the LED will blink to indicate that the timer is counting. The watchdog timer is automatically disabled after reset. Once you have enabled the watchdog timer, your program must trigger the watchdog timer every time before it times-out. After you trigger the watchdog timer, it will be set to zero and start to count again. If your program fails to trigger the watchdog timer before time-out, it will generate a reset pulse to reset the system or trigger the IRQ15 signal to tell your program that the watchdog is times out. The factor of the watchdog timer time-out constant is approximately 6 seconds. The period for the watchdog timer time-out period is between 1 to 7 timer factors. If you want to reset your system when watchdog times out, the following table listed the relation of timer factors between time-out periods. Time Factor Time-Out Period (Seconds) 80H 3 81H 6 82H 12 83H 18 84H 24 85H 30 86H 36 87H 42 Table 4-1 Time-Out Setting 4-4 AR-B1542 User’s Guide If you want to generate IRQ15 signal to warn your program when watchdog times out, the following table lists the relation of timer factors and time-out period. And if you use the IRQ15 signal to warn your program when the watchdog times out, enter the BIOS Setup the menu, the and items must set to Primary. Time Factor Time-Out Period (Seconds) 0C0H 3 0C1H 6 0C2H 12 0C3H 18 0C4H 24 0C5H 30 0C6H 36 0C7H 42 Table 4-2 Time-Out Setting NOTE: 1. If you program the watchdog to generate IRQ15 signal when it times out, you should initial IRQ15 interrupt vector and enable the second interrupt controller (8259 PIC) in order to enable CPU to process this interrupt. An interrupt service routine is required too. 2. Before you initial the interrupt vector of IRQ15 and enable the PIC, please enable the watchdog timer previously, otherwise the watchdog timer will generate an interrupt at the time watchdog timer is enabled. 4.3.2 Watchdog Timer Enabled To enable the watchdog timer, you have to output a byte of timer factor to the watchdog register whose address is 76H. The following is a BASICA program, which demonstrates how to enable the watchdog timer and set the time- out period at 24 seconds. 1000 REM Points to command register 1010 WD_REG% = 76H 1020 REM Timer factor = 84H (or 0C4H) 1030 TIMER_FACTOR% = %H84 1040 REM Output factor to watchdog register 1050 OUT WD_REG%, TIMER_FACTOR% .,etc. 4.3.3 Watchdog Timer Trigger After you enable the watchdog timer, your program must write the same factor as enabling to the watchdog register at least once every time-out period to its previous setting. You can change the time-out period by writing another timer factor to the watchdog register at any time, and you must trigger the watchdog before the new time-out period in next trigger. Below is a BASICA program, which demonstrates how to trigger the watchdog timer: 2000 REM Points to command register 2010 WD_REG% = 76H 2020 REM Timer factor = 84H (or 0C4H) 2030 TIMER_FACTOR% = &H84 2040 REM Output factor to watchdog register 2050 OUT WD_REG%, TIMER_FACTOR% .,etc. 4.3.4 Watchdog Timer Disabled To disable the watchdog timer, simply write a 00H to the watchdog register. 3000 REM Points to command register 3010 WD_REG% = 76H 3020 REM Timer factor = 0 3030 TIMER_FACTOR% = 0 3040 REM Output factor to watchdog register 3050 OUT WD_REG%, TIMER_FACTOR% ., etc. 4-5 AR-B1542 User’s Guide 5. BIOS CONSOLE This chapter describes the BIOS menu displays and explains how to perform common tasks needed to get up and running. It also presents detailed explanations of the elements found in each of the BIOS menus. The following topics are covered: � BIOS Setup Overview � Standard CMOS Setup � Advanced CMOS Setup � Advanced Chipset Setup � Power Management � PCI/Plug and Play � Peripheral Setup � Auto-Detect Hard Disks � Password Setting � Load Default Setting � BIOS Exit 5.1 BIOS SETUP OVERVIEW The BIOS is a program used to initialize and set up the I/O system of the computer, which includes the PCI bus and connected devices such as the video display, diskette drive, and the keyboard. The BIOS provides a menu-based interface to the console subsystem. The console subsystem contains special software, called firmware that interacts directly with the hardware components and facilitates interaction between the system hardware and the operating system. The BIOS default values ensure that the system will function at its normal capability. In the worst situation the user may have corrupted the original settings set by the manufacturer. After the computer is turned on, the BIOS will perform diagnostics on the system and display the size of the memory that is being tested. Press the [Del] key to enter the BIOS Setup program, and then the main menu will show on the screen. The BIOS Setup main menu includes some options. Use the [Up/Down] arrow key to highlight the option that you wish to modify, and then press the [Enter] key to select the option and configure the functions.

PROGRAMMING RS-485 & INDEX 8.1 PROGRAMMING RS-485 The majority communicative operation of the RS-485 is in the same of the RS-232. When the RS-485 proceeds the transmission which needs control the TXC signal, and the installing steps are as follows: Step 1: Enable TXC Step 2: Send out data Step 3: Waiting for data empty Step 4: Disable TXC NOTE: Please refer to the section of the “Serial Port” in the chapter “System Control” for the detail description of the COM port’s register. (1) Initialize COM port Step 1: Initialize COM port in the receiver interrupt mode, and /or transmitter interrupt mode. (All of the communication protocol buses of the RS-485 are in the same.) Step 2: Disable TXC (transmitter control), the bit 0 of the address of offset+4 just sets “0”. NOTE: Communicates the AR-B1542 CPU card’s DTR signal with the RS-485’s TXC signal. (2) Send out one character (Transmit) Step 1: Enable TXC signal, and the bit 0 of the address of offset+4 just sets “1”. Step 2: Send out the data. (Write this character to the offset+0 of the current COM port address) Step 3: Wait for the buffer’s data empty. Check transmitter holding register (THRE, bit 5 of the address of offset+5), and transmitter shift register (TSRE, bit 6 of the address of offset+5) are all sets must be “0”. Step 4: Disabled TXC signal, and the bit 0 of the address of offset+4 sets “0” (3) Send out one block data (Transmit –– the data more than two characters) –– Step 1: Enable TXC signal, and the bit 0 of the address of offset+4 just sets “1”. Step 2: Send out the data. (Write all data to the offset+0 of the current COM port address) Step 3: Wait for the buffer’s data empty. Check transmitter holding register (THRE, bit 5 of the address of offset+5), and transmitter shift register (TSRE, bit 6 of the address of offset+5) are all sets must be “0”. Step 4: Disabled TXC signal, and the bit 0 of the address of offset+4 sets “0” (4) Receive data The RS-485’s operation of receiving data is in the same of the RS-232’s. 8-2 AR-B1542 User’s Guide (5) Basic Language Example a.)
