DESCRIPTION
The ISO-232-8E is an industrial-grade, externally powered, bi-directional 2500V (2500Vrms min AC) optically isolated RS232 port 8 wire isolator in a 9 pin format. The ISO-232-8E optically isolates the 8 lines: TX, RX, CTS, RTS, DTR, DSR, RI and GND which effectively protects your RS232 devices from transient surges, lightning strikes, ground loops and noise issues. This is a high speed isolator which is externally power eliminating the possibility your RS232 devices will not power the converter. It also supports data direction auto-turnaround requiring no flow control. The ISO-232-8E has a DB9 female connector on one RS232 side and a DB9 male connector on the other RS232 side. The unit is enclosed in a heavy duty aluminum housing and includes a power supply and two serial cables for convenience. This converter operates from 300 to 115,200 baud.

Using one ISO-232-8E unit:
- Check that all connections comply with the connection diagrams.
- Perform a loop back test on one unit:
-
- Connect the power adapter to the ISO-232-8E
- Connect the ISO-232-8E in between RS-232 path.
- If there is continuity in the data stream then it is working. If the ISO-232-8E is not being powered it will not work at all.
- When power is on the RED light will be on. When data is being transmitted the GREEN light will flash. When data is being received the YELLOW light will flash.
