OPTO-ISOLATED RS232 REPEATER
(PORT-POWERED/3-WIRE) |
|
|
 |
|
The RPT-232-3 is an optically
isolated RS-232 data repeater (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 transient surges,
ground loop, and remote lightning.
The unit is powered from
the RS-232 data line, and therefore, no external power or RTS,
DTR is required.

The RPT-485_422-2 is a RS-485/RS-422
repeater/converter, which can be used to extend the RS-485
or RS-422 distance to up to 4000 ft (1.2km). It
can also be used to convert a two-wire RS-485 signal into a
four-wire RS-422 signal, and vice versa.
This
product features data direction auto-turnaround. Therefore,
no flow control is required.
