INDUSTRIAL MULTI-MODE RS232/RS485/RS422 TO FIBER OPTIC CONVERTER

Serialcomm - MODEL SER-FIBER-MM

Fiber optic transmission has many benefits over copper wire systems, including large bandwidth, immunity to EMI/RFI and lightning, protection from high current electrical exposure, chemical corrosion and atmospheric conditions. Serial and Ethernet systems can be converted to fiber optic and transmitted over long distances using serial/Ethernet fiber optic converters (modems).

Sima S. Enterprises offers a diverse selection of high quality, high performance, RS232 / RS485 / RS422 to fiber optic media converter products from Serialcomm the choice manufacturer of low priced data communication products without sacrificing quality and reliability. All of our products are CE, FCC and RoHS certified by a reputable independent 3rd party testing facility and backed by our 30 day money back guarantee and 5 year warranty.

DESCRIPTION

The SerialComm SER-FIBER-MM is a high quality industrial-grade bi-directional externally powered RS-232 / RS-485 / RS-422 to multi-mode (MM) fiber optic converter (fiber optic modem) enclosed in a heavy-duty steel housing. Besides the capability of long distance data transmission, fiber lines are inherently resistant to EMI/RFI and transient surges including lightning; therefore, they are ideal for data communications near heavy electrical equipment and other electrical or atmospheric interference conditions. The multi-mode fiber optic converter can extend the RS232 / RS485 / RS422 signal distance to up to 1.2 miles (2 km) using MM fiber optic cable. The RS232, RS485, and RS422 can be connected in any configuration; for instance RS232 can be converted to RS485 or RS422 via fiber. The unit supports serial data rates up to 460kbps and features auto-sensing data turnaround and therefore requires no flow control or any software drivers, The converter has no DIP switches or jumpers making it Plug-and-Play. The 232-FIBER-MM has a terminal block connector for easy installation and either ST type or SC type connectors for the fiber optic links which needs to be specified. The media converter is wall, panel, or DIN rail mountable. Free optional DIN rail mounts are available at checkout for this converter. An external 9V-36V / 100V-240V power adapter is included in package. This product is backed by our 30 day money back guarantee and 5 year warranty.

FLEXIBLE SERIAL CONVERSION

This serial converter is very versatile.  Not only can you extend RS-232, RS-485 or RS-422 data but convert from one serial protocol to another.  For instance on one end of the fiber optic you can connect RS-232 and the other RS-485 or RS-485 to RS-44 or any other combination.

TROUBLESHOOTING INSTRUCTIONS

 

Using one SER-FIBER-MM unit:

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 SER-FIBER-MM 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 SER-FIBER-MM 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.

Using two SER-FIBER-MM units:

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 SER-FIBER-MM 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 SER-FIBER-MM 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.
