RESET
0
Initialize machine 0
When the machine is initialized, it sends the
RESET code (DATA = 0). If the machine receives
this code, it resets to its “power-up” state.

Configure the
machine to its
factory default
state
0
When the machine receives this code, all
programmable parameters are reset to their factory-
default values.

If the machine receives an invalid instruction, it
replies by sending this error code.

switch value*
The PC sends a value directly to the machine. If
valid, the machine implements this new value, and
replies by sending the same data back to the PC.
Note that the addressed front-panel switch does not
need to be pressed in order to change its value via
RS-232.
If the “+” or “-” button is pressed on the machine,
resulting in a change in a switch value, then this
switch number and value is sent to the PC.

Request software
version number
0
If the software version is requested, the machine
replies with DATA as the version number before
the decimal point, and EXTENDED DATA is the
value following the decimal point. For example, for
version 3.4, the machine replies with DATA = 03
(hex), and EXTENDED DATA = 04 (hex).
