Null Command
Syntax: <SOH>Z<CR>
Description: 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.
Response: <SOH>0<CR> Positive response.
Output Identity
Syntax:
<SOH>OI<CR>
Description:
Returns a 6-character random identifier, which describes the controller type and the
firmware version number.
Response:
<SOH>CcXxxx<CR>
where:
Cc = Two ASCII characters that describe the type of 3M™ MicroTouch™
controller.
Xxxx = Four ASCII characters that indicate a build identifier.
Parameter Set
Syntax:
<SOH>Ppds[b]<CR>
where:
p = Parity type
N = No parity
O = Odd parity
E = Even parity
d = Number of data bits (7 or 8).
s = Number of stop bits (1 or 2)
b = Communication rate
1 = 19200 baud 4 = 2400 baud
2 = 9600 baud 5 = 1200 baud
3 = 4800 baud
Description:
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.
