Chapter 2 Communicating with the MT3000 Controller 35
AutoBaud Enable
Syntax:
<SOH> AE <CR>
Description:
Turns on the automatic baud rate detection feature.
When you enable AutoBaud, the controller changes its communication rate
to that of the next command from the host system. Thereafter, the controller
sets its communication rate to the first command received from the host
system after powering on the unit.
Although the AutoBaud Enable command sets the communication rate, it
does not automatically set the parity, the number of data bits, and the
number of stop bits. The controller cannot communicate with the host
system unless all communication parameters are the same.
AutoBaud Enable is the factory default for some touchscreen controllers.
However, because this automatic feature is limited to the communication
rate, MicroTouch recommends that you issue an AutoBaud Disable
command to turn off the AutoBaud feature. After you disable AutoBaud,
send a Parameter Set command to change the communication parameters
(parity, number of data bits, number of stop bits, and baud rate).
Response:
<SOH> 0 <CR> Positive response.
