For example, to see the analyzer lamp temperature set point, the host computer would issue the 
command: 

"V ALAMP_SET<CRLF>" 

and the CPU would respond with something like: 

"V  DDD:HH:MM  IIII  ALAMP_SET=25 20 30 <0-100><CRLF>" 

indicating that the current set point is 25 degrees, the warning limits are 20 to 30 degrees, and 
the data entry limits are 0 to 100 degrees. 

To modify a variable's value, almost the same format of command is used: 

"V VARIABLE=VALUE WARNLO WARNHI<CRLF>" 

The "VARIABLE" field is the name of the variable being modified, and the "VALUE" field is 
the new value. "WARNLO" and "WARNHI" are the low and high warning limits, respectively, 
and may only be given if the variable uses warning limits. They are optional for variables which 
use warning limits and, if not given, the warning limits are not changed.  

After changing the variable's value, the CPU will respond with: 

"V VARIABLE=VALUE WARNLO WARNHI [DATALO-DATAHI] <CRLF>" 

which should reflect the new value. The values in square brackets are not required for all 
variables. If needed, the values are included on the command line, separated by spaces. For 
example, to change the instrument ID, the host computer would issue a command like this: 

"V MACHINE_ID=1234<CRLF>" 

and the CPU should respond with: 

"V  DDD:HH:MM  IIII  MACHINE_ID = 1234 (0-9999)<CRLF>" 

Table 7-9 lists the variable names which are variable through the RS-232 interface and their 
corresponding button sequences.
