DIN-191
The DIN-191 module
transparently converts RS-232 signals to those required by RS-485 at all
standard baud rates from 300 to 115.2K baud. Internal control circuitry
automatically controls the flow of data on the RS-485 bus. Therefore, the
DIN-191 does not require external handshaking signals.
The DIN-191 is
optically isolated from the RS-232 input to the RS-485 output by up to
500VAC and contains internal biasing and termination resistors for the
RS-485 bus.

DIN-192
The DIN-192 module
transparently repeats RS-485 signals at all standard baud rates from 300 to
115.2K baud. Internal control circuitry automatically controls the flow of
data on the RS-485 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 RS-485 port.
