*OPT? — option identification query
Determine which options are installed in the
Model 2002.
The response message is made up of two comma separated fields. The first field indicates the
presence or absence of extra memory.
0 No extra memory (8k bytes volatile)
MEM1 Memory Option 1 (32k bytes non-volatile)
MEM2 Memory Option 2 (128k bytes non-volatile)
The second field indicates the presence or absence of the Model 2001-SCAN scanner card.
0 No scanner card installed
2001-SCAN Model 2001-SCAN installed
Example: The following response message indicates that Memory Option 2 and the scanner
card are installed:
MEM2, 2001-SCAN
PRINT #1, "output 16; *opt?" ' Query installed options
PRINT #1, "enter 16" ' Send response message to 2002
*RCL —recall
Return to a setup stored in memory.
No extended Model 2002-MEM1 Model 2002-MEM2
memory installed installed
<NRf> = 0 <NRf> = 0 to 4 <NRf> = 0 to 9
This command is used to return the Model 2002 to a setup configuration stored at a memory
location. The *SAV command is used to store a setup configuration at a memory location (see
paragraph 3.10.10).
If the Model 2002 does not have any extended memory installed, only one setup configuration
can be saved and recalled. In this situation, memory location “0” is the only valid parameter for
the *RCL command. If the Model 2002-MEM1 memory element is installed, up to five setup
configurations can be saved and recalled. In this situation, memory locations “0” through “4”
are valid parameters. If the Model 2002-MEM2 memory element is installed, up to 10 setup
configurations can be saved and recalled. Memory locations “0” through “9” are then valid
parameters.
The Model 2002 is shipped from the factory with :SYSTem:PRESet defaults loaded into the
available setup memories. If a recall error occurs, the setup memories default to the
:SYSTem:PRESet values.
PRINT #1, "output 16; *rcl 0" ' Recall setup stored at memory location 0
