OPTO-ISOLATED RS232 TO RS485
RS422 CONVERTER (SELF-POWERED)
|
|
|
 |
|
The CVT-485_422-3 is an
optically isolated RS-232 to RS-485 / RS-232 to RS-422
converter, which can be used to convert any standard RS-232C
port into a two-wire half-duplex RS-485 port or a four-wire
full-duplex RS-422 port and vice versa.
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
(self-powered); it
also supports data direction auto-turnaround. Therefore, no
external power or flow control is required.

RS232 ISOLATOR (SELF-POWERED /
3-WIRE)
|
|
|
|
|
The CVT-232A-3 optically
isolates three (3) RS-232 lines (TX, RX and GND), which
effectively protects your RS-232 devices from transient
surges, ground loop, and remote lightning. Optical isolation
also eliminates ground loop and noise problems.
The unit is powered from the RS-232 data line
(self-powered), and therefore,
no external power or RTS, DTR is required.

RS232 ISOLATOR (SELF-POWERED /
7-WIRE)
|
|
|
|
|
The CVT-232B-3 optically
isolates seven (7) RS-232 lines (TX,
RX, RTS, CTS, DTR, DSR and GND), which
effectively protects your RS-232 devices from transient
surges, ground loop, and remote lightning. Optical isolation
also eliminates ground loop and noise problems. The unit is powered from the RS-232 data line
(self-powered), and therefore,
no external power or RTS, DTR is required.
