PCL-844+ 8-port Intelligent RS-232/422 ISA Communication Card Features RISC Processor (TMS 320) 512 KB dual-port RAM Transmission speed up to 921.6 kbps with eight ports on-line Complete RS-232 modem control signals Maps to just 16 KB of system memory. Choose one of six addresses from C8000 to DC000. Many IRQ options: 2, 3, 4, 5, 7, 10, 11, 12 or 15 Easy-to-use menu driven installation program LEDs on connection box let you monitor the TxD/RxD status of any port Links to peripherals up to 1200 m (4000 ft) from controller (RS-422) Surge protection: 2500 VESD, 2000 VEFT (Optional) Introduction The intelligent PCL-844+ was designed as a 8-port RS-232 or RS-422 interface card for lab and industrial applications where a PC needs to communicate with terminals, modems, or other instruments. RS-422 applications use the optional Opt-8F/8Z 8-port RS-232 to RS-422 converter, shown 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. 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 multiple ports, servicing the interrupts alone consumes a large percentage of the capacity of your computer's CPU. The PCL-844+ serves as a high speed, dedicated interrupt processor. Its CPU directly controls the board's CD180 RISC-based UART, guaranteeing 921.6 kbps performance of over eight high-speed data ports. PCL-844+ is virtually a self contained computer in its own right. It contains 512 KB of dual-port RAM which you can use to store and run programs. The dual-port RAM maps into the host system's address space to give you the fastest possible data transfers between PCL-844+ and the PC memory. When the PCL-844+ initializes, it downloads the driver software (which functions like a PC's BIOS) into on-board SRAM. This improves performance and makes version upgrading easy, with no hardware redundancy.
