DESCRIPTION
The SerialComm CON-485-PI9 is a very high quality and reliable industrial-grade compact bi-directional port-powered RS232 to RS485 converter which converts full-duplex RS232 to a half-duplex two-wire RS485. 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). 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. This device is truly plug-and-play and simple enough for the novice. The CON-485-PI9 has a DB9 female connector on the RS232 end, and a built-in terminal block on the RS485 end.

Using two CON-485-PI9 units:
Check that all connections comply with the connection diagrams. Perform a loop back test on two units: Connect the two RS485 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-PI9 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-PI9 units are working properly.
