Applications
Troubleshooting
- Perform a loop back test on one unit:
- Plug the power connector to the converter. Both the PWR light and RX light should be on. Connect the fiber optic in to fiber optic out. Only the PWR light should be lit. Connect the RS-232 port to the PC RS-232 port. Running a hyper terminal program on the PC, send ASCII characters to the 232-FIBER-SM 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 232-FIBER-SM unit is working properly. When data is transmitting to the converter the TX light should blink and when the converter is receiving data the RX light should blink.
- Check that all connections comply with the connection diagrams.
- Perform a loop back test on two units:
- Plug the power connector to the converter. Both the PWR light and RX light should be on both units. Connect the fiber optic in of one converter and fiber optic out to the other converter. Connect the fiber optic out of one converter and fiber optic in of the other converter. Only the PWR light should be lit on both converters. Connect the two RS-232 ports to two PC RS-232 ports. Running hyper terminal programs on both PCs, send ASCII characters to the 232-FIBER-SM 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 232-FIBER-SM units are working properly. When data is transmitting to the converter the TX light should blink and when the converter is receiving data the RX light should blink.

The converter works as it should. My only qualm would be the price. At the time of the review, it costs $146. However, it comes with a 5 year warranty and has a built-in 600W Surge and 15KV static protection, so I am not removing a star for the cost because you often get what you pay for.Made in the USA.5 out of 5 stars.
