About 1784-PKTX
The Allen-Bradley 1784-PKTX is a network interface cards that directly mounts to a Peripheral Connect Interconnect (PCI) port of a personal computer. This card supports PCI bus version 2.3 and allows the host computer to connect to a Data Highway Plus (DH+), Remote I/O (RIO) or DH-485 communication network. This card may be used to interface with Programmable Logic Controllers (PLC) for implementing process visualization.
It has a single channel DH+ / RIO combo port, labelled as channel 1A and DH-485 communication interface labelled as Channel 1C. DH+ and RIO supports long distance communication with specific coverage limited by the transfer rate. Specifically, 10,000 ft. (3048 m) @ 57.6K bit/s; 5, 000 ft. (1,524 m) @ 115.2K bits/s and 2,500 ft. (762 m) @ 230.4K bits/s. For DH-485, maximum distance that may be covered is 4,000 ft. (1219 m) @ 1200, 2400, 4800, 9600 or 19,200 bits/s.
The 1784-PKTX comes with 1 diagnostic/status LED per channel and supports a maximum of Four (4) modules per system, specified by the jumper configuration. Drive development may be configured in variety of ways and depends on the operating system.
