INDUSTRIAL EXT. POWERED ISOLATED RS232 TO 2 W RS485 / 4 W RS422

DESCRIPTION

The SerialComm CON-485/422-EE9 is a very high quality and reliable industrial-grade bi-directional externally-powered 2.5K isolated RS232 to RS485 or RS422 converter which converts full-duplex RS232 to a half-duplex two-wire RS485 or 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 -40ºF to 185ºF (-40ºC to 85ºC). This converter features auto sensing data turnaround eliminating the need for software drivers or handshake flow control. The CON-485/422-EE9 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-EE9 has a DB9 female connector on the RS232 end, and either DB9 male or RJ45 connectors on the RS485/RS422 end. Two terminal blocks are included one for the RS485 and other for RS422. The terminal blocks plug into the RS485/RS422 port, providing screw-lug wire terminations for the port. The unit is enclosed in a heavy duty steel housing for rugged applications. This converter features optional DIN rail mounts.

TERMINAL BLOCK SELECTION GUIDE

The CON-485/422-EE9 two terminal blocks with optional built-in 120 ohm terminations. 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-485/422-EE9 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 RS485/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-485/422-EE9 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-EE9 unit is working properly.

Using two CON-485/422-EE9 units:

Check that all connections comply with the connection diagrams. Perform a loop back test on two units: Connect the two RS485 or 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-485/422-EE9 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-EE9 units are working properly.
