24 SC400 Controller Reference Guide
3M Touch Systems Proprietary Information
Description: This command is used to set a controller number for applications use. The controller does
not use this value. This is useful for identifying individual controllers in a multiple
controller system.
Unit Type
<SOH> UT <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>
where:
Tt = Two ASCII characters that identify the controller type.
SC Indicates the SC series of controllers
Ffff = Four ASCII characters that indicate the features supported by the
controller.
R Indicates a resistive controller
4 Indicates either 4 wire controller (SC400) or an 8 wire
controller (SC800)
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 in the status byte. Each bit
can be set to 1 or 0, where
1 = an error and 0 = no error. So a
response of:
00 = No diagnostic errors (normal response)
The SC400 running with no errors returns the following string:
<SOH> SCR4**00 <CR>
