DESCRIPTION:
The SerialComm CON-422-PIE is an industrial grade bi-directional port powered or external powered RS232 to RS-485 converter which converts a full-duplex RS-232C port to a full-duplex four-wire RS-422 port.
A built-in data direction auto-turnaround feature automatically enables the RS-422 driver when data is
present from the RS-232 port, eliminating the need for software drivers, and making the device fully plugand-play. The CON-422-PIE has a db-9 female connector on the RS-232 serial port, and db-9 male
connector on the RS-422 port. A separate terminal block is included with the product. The terminal
blocks plugs into the RS-422 port, providing screw-lug wire terminations for the port. The unit is enclosed
in a rugged ABS housing, and is powered from the RS-232 data lines; no external power is required.

PORT POWERED WITH OPTIONAL EXTERNAL POWER:
The SerialComm CON-422-PIE has an optional 5V DC external power input, The CON-422-PIE is
normally port-powered from the RS-232 data lines while using a capacitor charge pump built into the
converter to provide necessary power. There are rare instances where the RS-232 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.
Because the CON-422-PIE is industrial grade and port-powered with an optional 5V power input it makes
this converter one of the most versatile RS-232 to RS-422 converters on the market.

TROUBLESHOOTING INSTRUCTIONS:
Using one CON-422-PIE unit:
1. Check that all connections comply with the connection diagrams.
1. Perform a loop back test on one unit:
a) Connect the T/R+ to RXD+ and T/R- to RXD- on the RS-422 port.
b) Connect the RS-232 port to the PC RS-232 port.
c) Running a hyper terminal program on the PC, send ASCII characters to the CON422-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:
a) Connect the two RS-422 ports.
b) Connect the two RS-232 ports to two PC RS-232 ports.
c) Running hyper terminal programs on both PCs, send ASCII characters to the CONnd
422-PIE converter from one PC port, and check that the characters are received at the 2
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.
