RS-232
Industrial Media Converter
COMPACT, RUGGED &
TEMPERATURE HARDENED
Introduction
This Industrial Serial Data media converter transports a full 9-Pin
RS-232 copper signal over fiber optic cable. This is an ideal
solution for extending serial data communications over long
distances or near large electrical equipment. Fiber optics provide
long distance communication up to 74 mi. (120km) and immunity
to EMI/RFI and potential transient surges which can cause noise
or damage equipment.
The system supports asynchronous serial data rates from 50 bps
to 1Mbit/s and has an auto-sensing feature that eliminates the
need to manually set serial data rates. A comprehensive set of
LEDs on the front panel indicate power status, fiber status, and
serial data activity. Powering options include standard 24-48VDC
or high range DC powering of 125VDC. This rugged system is
designed to operate over a wide operating temperature -40 to
+70°C and features dual redundant power inputs, and a system
alarm relay for maximum uptime and reliability. Included is a DIN
clip and wall mount ears for easy installation into to a wide range
of environments.
