DESCRIPTION
The SerialComm CON-422-PE9 is a very high quality and reliable bi-directional port-powered RS232 to RS422 converter which converts full-duplex RS232 to a full-duplex four-wire RS422. The converter can extend the distance of the RS232 for up to 4000 ft (1.2km). This converter is ideal for any demanding application whether indoor in a lab, server room, office, at home or outdoors within the temperature range of -4ºF to 140ºF (-20ºC to 60ºC). The converter is port-powered and derives power by amplifying the RS232 data lines requiring no external power at all. This converter features auto sensing data turnaround eliminating the need for software drivers or handshake flow control. The CON-422-PE9 has a DB9 female connector on the RS232 end, and DB9 male connector on the RS422 end. Two separate terminal blocks, a rugged terminal block with no exposed jumpers and a terminal block with built-in selectable 120 Ohm termination via jumper are included with the product for maximum flexibility. The terminal blocks plug into the RS422 end of the converter, providing screw-lug wire terminations for the port.

TERMINAL BLOCK SELECTION GUIDE
The CON-422-PE9 comes with two terminal blocks for maximum performance and flexibility. One terminal block is a rugged terminal block which is sealed to provide protection from the elements and vibration. The other terminal block has a built-in 120 Ohm termination selectable by a jumper on the terminal block. Both terminal blocks include fastening hardware.

TERMINATION GUIDE
The CON-422-PE9 terminal block has an optional built-in 120 ohm termination. 120 ohm termination is an advanced feature typically used to reduce noise and signal reflections. It is recommended to use 120 Ohm termination if you are exceeding 600 feet in distance, 19.6K baud or in a noisy environment. The terminal blocks are shipped with 120 Ohm termination off but can be turned on using the convenient jumper setting located on the left bottom of the terminal block.

Using one CON-422-PE9 unit:
Check that all connections comply with the connection diagrams. Perform a loop back test on one unit: Connect the TX+ to RX+ and TX- to RX- on the RS422 port. Connect the RS232 port to the PC RS232 port. Running a hyper terminal program on the PC, send ASCII characters to the CON-422-PE9 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-PE9 unit is working properly.
Using two CON-422-PE9 units:
Check that all connections comply with the connection diagrams. Perform a loop back test on two units: Connect the two RS422 ports. Connect the two RS232 ports to two PC RS232 ports. Running hyper terminal programs on both PCs, send ASCII characters to the CON-422-PE9 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-PE9 units are working properly.
