The
FBR-Serial-2 (Rack/Wall-mount) is
a
rugged,
light-weight, industrial-grade,
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 optic products 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.
This
industrial Serial-to-Fiber-Optic converter
is enclosed in a heavy-duty, rustless ABS housing (the
improved version of our previous steel housing), it
operates within a
temperature range of -40ºF to 185ºF (-40ºC to 85ºC), and
features 600W surge protection and 15kV static protection.
The unit
supports
128 nodes of RS485 / RS422 devices and come with
data format auto-sensing and
self-adjusting, therefore, no DIP switch, jumper settings or
software drivers are required,
making it a highly reliable and truly plug-and-play
device. Depending
on the fiber cable and the type of converter used, a
Single-Mode
fiber optic converter can extend the RS232 / RS485 / RS422
distance to up to 24.8 miles (40 km), while a
Multi-Mode fiber optic converter can extend the RS232 /
RS485 / RS422 distance to up to 1.2 miles (2 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
FBR-Serial-2 comes with the options of ST, SC and FC
connectors for fiber optic links, and, thanks to the
professional and unique casing design, the product can be
mounted directly on a wall, panel, rack or DIN Rail, without a need of
using any unsecured DIN-Rail or wall-mount adapters. A
separate external power supply is included in the package,
and the
unit is backed by our 30-day risk-free money-back
guarantee and 5-year replacement warranty.
Baud
rates: 300 to 115.2K Baud.

TROUBLESHOOTING
RS232 RS485 RS422 TO FO CONVERTER
1) Make sure the power is connected and turned on.
2) Check the connections according to the above
“CONNECTIONS” diagrams.
3) Loopback Test
Figure 4: LOOPBACK TEST
-
Connect “Fiber TX” to “Fiber RX” by using a fiber optic
patch cord cable and connect the PC’s RS-232 (or
RS-485/422) to FBR-Serial-2 according to the above
“CONNECTIONS” diagram.
-
Run 232Analyzer
FREE version software on your computer.
-
Select "ASCII" for both the Send and Receive data
formats. Then send command and/or string such as
"CommFront" from the 232Analyzer software. You should
receive an echo of the command/string sent
("CommFront"). By performing a simple loopback test like
this, you can test both the transmitter and receiver of
the converter. This is very helpful when you are in
doubt about the performance of your converter.
Screenshot: Send/receive
commands from 232Analyzer software.
232Analyzer is an advanced RS232 Serial Protocol Analyzer
software
that allows you to control, monitor and analyze serial port
(RS232 / RS485 / RS422 / TTL, etc.) activities.
Not just the data,
it also allows you to monitor or change RS-232's line
states: RTS, CTS, DTR, DSR, DCD, and RI.
