The
FBR-Serial-2 is a multi-function RS232 / RS485 / RS422 to fiber optic
converter (fiber optic modem) that supports asynchronous
serial communications (RS-232, RS-485, and RS-422) through
fiber optic links. Besides the capability of long distance
data transmission, fiber lines are inherently resistant to
EMI/RFI and transient surges; therefore, they are ideal for
data communications near heavy electrical equipment and
other electrical or radio interference.
Depending
on the fiber cable and the type of converter used, a
multi-mode fiber optic converter can extend the
RS232 / RS485 / RS422 distance to up to 1.2 miles (2 km), while a
single-mode fiber optic converter can extend the
RS232 / RS485 / RS422 distance to up to 12.4 miles (20 km).
Standards can be mixed and matched, so RS-232 devices can be
connected to RS485 / RS422 devices, or RS485 (2-wire) devices
can be connected to RS422 (4-wire) devices without using a
converter and isolator.
The
unit supports serial data rates up to 460kbps and features
data format auto-sensing and self-adjusting, and, therefore,
no DIP switch or jumpers are required. When working with
RS485 signals, the CommFront’s auto-turnaround feature
eliminates the need for flow control.
