Restore Defaults
Syntax:
<SOH>RD<CR>
Description:
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 12 lists the factory defaults for the EX serial controller. The Restore Defaults
command is useful in situations where inadvertent commands to the controller have
rendered the sensor inoperative.

The Restore Defaults command requires approximately 1.8 seconds. Therefore, the

command response before issuing another command to the controller.
Note : After you issue a Restore Defaults command, you must recalibrate your sensor
using a 2-point calibration.
