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 sensor
using a 2-point calibration.
Response: <SOH>0<CR> Positive response.
Unit Type
Syntax: <SOH>UT<CR>
Description: 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).
Response: Returns an identification code up to 8 ASCII characters in the following format:
<SOH>TtFfffSs<CR>
where:
Tt
= Two ASCII characters that identify the controller type.
TP = pen controller
Ffff = Four ASCII characters that indicate the features supported by the controller.
**** = Indicates no additional features configured
Ss = Two ASCII characters that provide status information about the controller
hardware. The two characters represent one byte. Each character is in the range
0 to 9 and A to F.
Table 2 defines the meaning of each bit (LED minus 1) in the status byte. Each
bit can be set to 1 or 0, where:
1 =
Error
0 = No error
00 = No diagnostic errors (normal response)
