An example of each command is as follows:
'A' Command
- Alarm set point with low or high alarm option.
Alarm #1 will be set to go off in the case of the CO
2
level dropping below 20 ppm. Type:
A1=20.0L <Enter>
To change Alarm #1 to 18 ppm instead of 20 ppm you could type:
A1=18 <Enter>
Note how the 'L'ow alarm is optional unless changing to 'H'igh? As you can see, the decimal point is
optional too, and if left out defaults to '.0'. Note how the command in the help screen says,
"[bb.b]&/or[L/H]"? Examine the following example:
A1=H <Enter>
This is a valid command and will only effect the 'L'ow or 'H'igh status of Alarm 1. To set it back to a low
alarm type:
A1=L <Enter>
'B' Command
- Baud change. To change the baud from 300 bps (default) to 9600 bps type the following:
Make sure the instrument is responding at 300 bps first.
B9600 <Enter>
Note that you may have some garbled data output. Now you must change your terminal's baud rate and
reestablish communication by pressing <Enter>.
'C' Command
- Calibrate to known calibration standard (i.e. 40 ppm).
Using a calibration gas consisting of 40 ppm, type the following:
C40 <Enter>
'D' Command
- Disable security with optional pass code. (See 'E' Command below for description of
security)
In it's simplest form, to disable security protection type:
D <Enter>
Assuming an 'E' Command had been sent with a pass code of "mypass1" (see next command example)
then type the following to disable the security option:
Dmypass1 <Enter>
Note: typing "DMYPASS1" will not disable the instrument if the original pass code was in lowercase! That
means that the 'D' and 'E' commands are CASE SENSITIVE.
'E' Command
- Enable security with optional pass code.
To keep others from changing any system settings, the 'E'nable Command is supplied as an optional
security measure. In it's simplest form type the following:
E <Enter>
