Description

The MD-12 is a short-haul modem allowing RS-232 systems to be connected over long distance. The serial interface is a standard RS-232 interface with five control signals. The connection between the modems is a balanced current loop allowing distances up to 18 km. (11.18 mi) Since the communication is totally transparent no communication settings are necessary. The RS-232 serial interface is connected through a standard 9-pole D-sub or alternately through a terminal block with screw connectors.

The MD-12 is designed for use in heavy-duty industrial applications. The different power options, galvanic isolation, and transient protection guarantee communication in the worst environments. The MD-12 has been tested to meet many EMC, isolation, vibration, and shock standards, all to the highest levels suitable for heavy industrial environments.

The design of the short-haul modem makes the MD-12 suitable for a variety of applications with various speeds and data bit options. DIP switches are used for configuration options of the control signals. One control signal can be transmitted in both directions.
