PCI-485-4

Description

The National Instruments PCI-485/4 Serial Interface, with part number 777641-04, is a robust solution for RS485 communications, supporting up to 32 devices on a single line, which can be expanded with the use of repeaters. Biasing is included by default to ensure a known “zero” state when all transmitters are off, while termination can be easily managed with jumpers on the card itself.

This card features automatic driver control, simplifying the enablement and disablement process during data transmission, and comes equipped with 9-pin male D-sub connectors for I/O connections. It is compatible with a variety of interfaces, including RS-232(PCI-COM2S), RS-422, and RS-485, making it highly versatile for different system configurations.

With the ability to handle character lengths of 5, 6, 7, or 8 bits and support for even, odd, or no parity, the PCI-485/4 card offers flexibility for serial data communication requirements. Despite its obsolete status as announced by National Instruments, the card remains available for purchase and servicing through Apex Waves.
