The DIN-192 module transparently repeats RS485 signals at all standard baud rates from 300 to 115.2K baud. Internal control circuitry automatically controls the flow of data on the RS485 bus. Therefore, the DIN-192 does not require external handshaking signals.  

The DIN-192 is optically isolated by up to 500VAC and contains internal biasing and termination resistors for each RS485 port.
