Westermo Teleindustri D-sub, 9-Pin (Serial) Interface Adapter

RS 422//485 converter

The MA-45 is used as an interface converter between RS-232 / V.24 and RS-422 / 485 or when point-to-point communication with speeds up to 155.2 kbit / s is required.The unit accepts communication over 2 or 4 wires over distances up to 1200 metres and with 32 loads in bus-oriented applications.For 2-wire communication, the direction of the communication is controlled via the data flow.The converter detects the data and changes the communication direction by reversing it in accordance with the arrival direction of the data.This makes it possible to connect equipment that is unable to process status signals. The MA-45 is a standalone unit.One or more repeaters make it possible to increase the communication distance or connect more units to the bus.

Its strengths:

Conversion between RS-232 / V.24 and RS-422 / 485.Communication direction controlled by the data flow or RTS.Galvanic insulation.Protection against lightning and transients.Independent of code / transparent.Reliable transmission over long distances in exposed environments.Excellent performance, great reliability.AC / DC power supply.
