Rugged Industrial, Isolated RS232 to RS485/RS422 Converter or RS485/RS422 Converter/Repeater

Model CON-485/422-REP

Category: RS232 / RS485 / RS422 Repeaters

DESCRIPTION

The CON-485/422-REP is a rugged industrial grade bi-directional externally powered 3K isolated RS232 to RS485/RS422 converter / RS485 to RS422 converter / RS485/RS422 repeater. This is our most versatile isolated RS232/RS485/RS422 converter and RS485/RS4324 repeater. Not only will it convert RS232 to RS485 or RS422 but it will convert RS485 to RS422 and vice versa and repeat either RS485/RS422 with isolation. A built-in data direction auto-turnaround feature automatically enables the RS485/RS422 driver when data is present from the RS232 port, eliminating the need for software drivers, and making the device fully plug-and-play. The CON-485/422-REP is an effective solution for protecting RS232, RS485 and RS422 devices from voltage surges, lightning strikes, ground loop conditions and signal noise problems. The unit is not reliant on port power so you do not have to worry about the RS232's ability to power the converter. The CON-485/422-REP has a DB9 female connector on the RS232 serial port, and terminal blocks for both RS485/RS422 ports. Two terminal blocks are included; one for the RS485 and other for RS422. The terminal blocks provide screw-lug wire terminations for the port. The unit is enclosed in a heavy duty steel housing for rugged applications. This converter operates from 0 to 115,200 bps.

CON-485/422-REP Dimensions

Using one CON-485/422-REP unit:

  1. Check that all connections comply with the connection diagrams.
  2. Perform a loop back test on one unit:
    1. Connect the T+ to R+ and T- to R- on the RS-485/RS-422 port.
    2. Connect the RS-232 port to the PC RS-232 port.
    3. Running a hyper terminal program on the PC, send ASCII characters to the CON-485/422-REP converter from one PC port, and check that the characters are received at the same PC port. This tests that the transmit and receive functions of the CON-485/422-REP unit is working properly.

Using two CON-485/422-REP units:

  1. Check that all connections comply with the connection diagrams.
  2. Perform a loop back test on two units:
    1. Connect the two RS-485 or RS-422 ports.
    2. Connect the two RS-232 ports to two PC RS-232 ports.
    3. Running hyper terminal programs on both PCs, send ASCII characters to the CON-485/422-REP converter from one PC port, and check that the characters are received at the 2nd PC port. Repeat the test in the opposite direction. This tests that the transmit and receive functions of both CON-485/422-REP units are working properly.
