Description:
<SOH>Z<CR>
Queries the controller and waits for a response.
Use Z to determine that you are communicating with the controller or to make sure that a
utility is communicating with the controller. Using this command does not affect the
controller’s current operating parameters.
<SOH>0<CR>
<SOH>OI<CR>
Returns a 6-character random identifier, which describes the controller type and the
firmware version number.
<SOH>CcXxxx<CR>
where:
Cc
Xxxx = Four ASCII characters that indicate a build identifier.
<SOH>Ppds[b]<CR>
where:
P
D
S

Lets you adjust the communication parameters (parity, data bits, and stop bits) of the
controller. Optionally, you can change the communication rate by appending an
additional character to the command string. Upon execution of the Parameter Set
command, the controller automatically stores the new settings, the current operating
mode, and the current data format in NOVRAM.
The communication parameters of the host system must match the present settings of the
controller when the command is given for it to be accepted and the changes implemented.
= Parity type
= Number of data bits (7 or 8).
= Number of stop bits (1 or 2)
= Communication rate
= Two ASCII characters that describe the type of 3M Touch Systems controller.
N = No parity
O = Odd parity
E = Even parity
