Response:
<SOH>0<CR>
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
Xxxx = Four ASCII characters that indicate a build identifier.
Parameter Set
Syntax:
<SOH>Ppds[b]<CR>
where:
= Parity type
p
= Number of data bits (7 or 8).
d
= Number of stop bits (1 or 2)
s
= Communication rate
b
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.
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.
The process of changing the parameters takes three steps:
•
The host system must first communicate with the controller using a matched set of
parameters.
•
The Parameter Set command is issued with the new parameters to the controller. The
new settings take effect immediately.
•
The host system must be changed to the new parameters in order to communicate
with the controller again.
Examples:

Positive response.
= Two ASCII characters that describe the type of 3M™ MicroTouch™
controller.
N = No parity
O = Odd parity
E = Even parity
1 = 19200 baud
2 =
9600 baud
3 =
4800 baud
Sets the serial line to no parity, eight data bits,
one stop bit, and 4800 baud.
