The EX II 1720SC controller operates at N, 7, 2.
<SOH>RD<CR>
Returns to the factory default operating parameters. The Restore Defaults command
copies the 3M Touch Systems factory default parameters from ROM to the non-volatile
memory (NOVRAM) and then executes a Reset command.
Table 10 lists the factory defaults for the EX II controller. The Restore Defaults
command is useful in situations where inadvertent commands to the controller have
rendered the touch screen inoperative.
Table 10 EX II Factory Default Settings
The Restore Defaults command requires approximately 1.8 seconds. Therefore, the
application program should wait the maximum amount of time and be sure it receives the
command response before issuing another command to the controller.
Note: After you issue a Restore Defaults command, you must recalibrate your touch
screen using a 2-point calibration.
<SOH>0<CR>
<SOH>UV<CR
Responds with an 8-character identity string. This string identifies the type of controller
currently attached to the system, lists the features supported by the controller, and outputs
the status of the controller hardware (a self-test code).
Returns an identification code up to 8 ASCII characters in the following format:
<SOH>TtFfffSs<CR>
