Industrial RS232 to RS422 Converter

Model CON-422-PIE

Category: RS232 to RS422 Converters

DESCRIPTION

The CON-422-PIE is an industrial grade bi-directional port powered or external powered RS232 to RS422 converter which converts a full-duplex RS232 port to a full-duplex four-wire RS422 port. A built-in data direction auto-turnaround feature automatically enables the 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-422-PIE has a DB9 female connector on the RS232 serial port, and DB9 male connector on the RS422 port. A separate terminal block is included with the product. The terminal blocks plugs into the RS422 port, providing screw-lug wire terminations for the port. The unit is enclosed in a rugged ABS housing, and is powered from the RS232 data lines; no external power is required. This converter operates from 300 to 115,200 baud.

FAIL-SAFE COMPLIANT:

This Industrial RS232 to RS422 converter is fail-safe compliant. When the RS422 port is in open, shorted, or terminated state the TX outputs are in a known Mark state (HIGH State). This insures the converter does not go in a unknown state during a fault condition.

PORT-POWERED WITH OPTIONAL EXTERNAL POWER:

The CON-422-PIE has an optional 5V DC external power input, The CON-422-PIE is normally port-powered from the RS232 data lines while using a capacitor charge pump built into the converter to provide necessary power. There are rare instances where the RS232 host device is not capable of port-powering the converter due to signal incompatibilities or low voltage levels. If this should occur, all that is necessary is adding a 5V DC external power to the terminal block or DB9 connector.

Using one CON-422-PIE unit:

  1. Check that all connections comply with the connection diagrams.
  2. Perform a loop back test on one unit:
    1. Connect the T/R+ to RXD+ and T/R- to RXD- on the 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-422-PIE 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-422-PIE unit is working properly.

Using two CON-422-PIE 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-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-422-PIE 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-422-PIE units are working properly.
