MMINTCONV

INTELLIGENT RS232/RS485 CONVERTER

The MMINTCONV unit is a bi-direction serial converter unit used to convert RS232 data communications signals for transmission over 2 or 4 wire RS485 (RS422) twisted pair cables. Each port is fully configurable via dipswitches for baud rate, parity, data bits, stop bits and full or half duplex modes. The converter can be used to communicate with RS422/RS485 devices and to extend the limited distance capabilities of RS232 devices such as printers and terminals for up to one kilometre. 

Standard features of the converter are: 

·         2 (RS485) or 4 (RS422)  Wire Operation.

External wire links are required to select 2 wire (RS485) mode. 

·         Baud Rate, Data Bits, Stop Bits, Parity and Half or Full Duplex Mode.

Each port is configurable via an 8way dipswitch. 

·         Signal Isolation.

    The converter module isolates the RS232 and RS485/RS422 signals to prevent ground loops between remote devices. 

·         DIN Rail Mount.

      The converter module plugs directly on to a DIN rail.
