The MD-45 is used to convert between RS-422/485 and RS-232/V.24 signals. This device is often used in multidrop applications connected to a PC or PLC. In 2-wire half duplex applications (RS-485) the direction of the bus can be controlled by data which means that the converter turns the bus depending on the data sent on the bus. This makes it possible to use the unit with equipment that has no handshaking signals. The maximum transmission rate possible is 115.2 kbit/s.
