5.1.3 Asynchronous Subrate Options

If your RS-232 serial device uses asynchronous subrates, select the appropriate options as shown
below.

Note that only one DS0 of the T1 can be cross connected to the RS-232 port in the Connections
menu.

When using an asynchronous rate, the Access Bank II must be used to terminate the opposite end of
the T1 circuit.

Data Size/Parity

Indicate the size of the data unit, either 7 or eight
bits; and whether to disable parity checking (for
eight-bit data units) or to use even or odd parity
checking (for seven-bit data units).

Stop Bits

Indicate whether to transmit one or two stop bits
for each byte of data transmitted.

Asynchronous Baud Rate

Select your serial device’s asynchronous baud
rate.
