When you select a new rate, the system locks the communication rate
that the controller must use. Disabling the AutoBaud feature lets the
controller automatically reset itself when power is applied at the
redefined communication rate. To lock in the communication rate,
power down the system for 10 seconds and then restart.
You may need to enable AutoBaud detection for certain applications
to work. If you enable the AutoBaud feature, Microcal polls the
controller and gets the default setting.
Communication Parameters
The communication parameters define the method of communications
between the controller and the RS-232 serial port. The
communication parameters define the following items:
Type of parity (N=none, E=even, and O=odd)
Number of data bits (7 or 8)
Number of stop bits (1 or 2)
