DESCRIPTION

The SerialComm ISO-232-3P9 is a high quality industrial grade (wide temperature range) high speed bi-directional port powered 5000V (5000Vrms min AC) optically isolated RS232 port isolator in a 9 pin format. It can optically isolate any standard full duplex RS232 port up to almost 1 mbps.. The ISO-232-3P9 optically isolates the 3 lines: TX, RX, and GND which effectively protects your RS232 devices from transient voltage spikes, lightning strikes, ground loops, and noise problems. The unit is powered from the RS232 data lines. therefore, no external power.  The isolator does not require any flow control or software drivers. The ISO-232-3P9 has a DB9 female connector on one RS232 side and a DB9 male connector on the other RS232 side.

TROUBLESHOOTING INSTRUCTIONS

 

Using one ISO-232-3P9 unit:

Check that all connections comply with the connection diagrams. Perform continuity test on one unit: Connect the ISO-232-3P9 in between RS-232 path. If there is continuity in the data stream then it is working.   If the ISO-232-3P9 is not being powered properly it will not work at all.

Perform a voltage test:

Check that all connections comply with the connection diagrams. Perform a detailed voltage test: Connect the ISO-232-3P9 in between RS-232 path. With a multi-meter perform the following test: Connect pin 1 to pin 5 and connect pin 2 to pin 3.  When static pin 2 should be 0V and pin 3 should be 5.5V.  When dynamic pin 2 should be 0V and pin 3 should be 3.7V.
