RS-422 applications use the optional • PLC monitoring and control Opt-8F/8Z 8-port RS-232 to RS-422 converter, shown • Instrument controller, distributed control system on the following page. You can install up to four PCL-844+ cards for a total of 32 ports in any AT/lSA bus-based PC. • Modem server, database server, POS controller • Multi-user system The PCL-844+ card has an on-board RISC processor that takes over the communications load from the host PC. When you are processing large amounts of data from Specifications multiple ports, servicing the interrupts alone consumes a large percentage of the capacity of your computer's CPU. Board The PCL-844+ serves as a high speed dedicated interrupt • Number of ports: 8 processor. Its CPU directly controls the board's CD180 • Processor: RISC, TI TMS320C203-57 RISC-based UART, guaranteeing 921.6 Kbps performance • Dual-ported RAM: 512 KB over eight high speed data ports. • SRAM: 16 KB The PCL-844+ is virtually a self contained computer in its • UART: RISC-based CD180 own right. It contains 512 KB of dual-port RAM which you can use to store and run programs. The dual-port RAM • Interrupt: 2, 3, 4, 5, 7, 10, 11, 12 or 15 maps into the host system's address space to give you the • Maximum ports in one system: 32 fastest possible data transfers between the PCL-844+ and • Operating temperature: 0 ~ 55° C (32 ~ 131° F) the PC memory. • Power consumption: When the PCL-844+ initializes, it downloads the driver +5 V @ 155 mA, +12 V @ 110 mA, -12 V @ 160 mA software (which functions like a PC's BIOS) into on-board • Weight: 0.8 kg (1.8 lb) SRAM. This improves performance and makes version upgrading easy, with no hardware redundancy. RS-232 Interface • Signals: The PCL-844+ comes with a communication utility package called PC ComLIB. The package consists of configurable TxD, RxD, RTS, CTS, DTR, DSR, DCD and GND DOS and Windows drivers, a programming library that • Mode: Asynchronous full duplex supports most common languages (such as C, Pascal, • Communication speed: 50 ~ 921.6 Kbps BASIC, assembly and Clipper) and DataScope. The PCI-1625 is the newest generation of intelligent 8-port communication • Data bits: 5, 6, 7, 8 card for PCI bus system. This card is equipped with the same • Stop bits: 1, 1.5, 2 high-performancing functions as PCL-884+. • Parity: Even, odd or none http://www.advantech.com 8-port Intelligent RS-232/422 Card Cable Wiring Features • RS-422 output for industrial and laboratory control Opt-8B: 8-port RS-232 Connection Box • 500 V isolation protection DC • Data transmission up to 1.2 km (4000 ft.) • LED indicators on each port indicate data flow Specifications • Speed: 50 ~ 921.6 Kbps • Isolation: 500 V min.
