Data (Bit) Rate
The RS-232 port supports asynchronous communications with the following baud
rates: 300, 600, 1200, 2400, 4800, 9600, 19200. The RS-232 port does not support
synchronous communication. There is no flow control with this port.
The RS-530 port supports asynchronous communications with the following baud
rates: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, and 57600. There is no flow
control with this port.
The RS-530 port also supports synchronous communication with data rates between
50000 bps and 2005000 bps. There is up to 4% of data rate error depending on the
rate selected. The data rate is only applicable when in Sync Internal mode. This is
when the OM-2000 is transmitting synchronous data and clock.
