INTRODUCTION (INDUSTRIAL RS232 REPEATER
/
EXTENDER / BOOSTER)
|
|
|
 |
|
The RPT-232-3 is an
industrial-grade
(wide
temperature range with surge & static protection) port-powered optically isolated
RS232 Repeater /
RS232 Extender (TX, RX, and GND), which
works in pairs to extend
the full-duplex RS-232 distance up to 1.8 miles (3 km). This
product features opto-isolation circuitry, which effectively
protect your RS-232 devices from
ground
loops, transient surges and spikes.
This industrial-grade RS232
repeater operates within a
wide temperature range (-40ºF
to 185ºF / -40ºC to 85ºC),
and features 600W surge protection and 15kV static
protection.
The unit is powered from the
RS-232 data line, and therefore, no external power or RTS,
DTR is required.

 Note:
Some software requires handshake line

converter's handshake lines are tied together (DCD,
DTR, and DSR tied together, and RTS and CTS tied
together). Therefore, you don't have to modify your
existing software. |

TROUBLESHOOTING INSTRUCTIONS
FOR RS232 ISOLATED REPEATER
|
| |
|
| |
1) Port power measurement |
| |
 |
| |
Note: The port-powered
RS232 repeater (RPT-232-3) requires a -7 to -15VDC on the TX
line (Pin 3 on DTE or Pin 2 on DCE) of the RS232 port to
which the repeater is connected.
You can connect RPT-232-3 to a
DTE device which comes with a DB-9 Male connector; however,
if it is a DCE device, you will need to swap Pin 2 and 3
before connecting to the repeater. |
| |
|
| |
2) Loopback Test |
| |
 |
| |
-
Connect an RPT-232-3 to your PC's COM port and short TX
and RX (TX+ to RX+, TX- to RX-) on the terminal block
(as shown above).
-
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 repeater. This is very helpful when you are in doubt
about the performance of your repeater.

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.
