Ieee488 Bus Commands - THORLABS ITC502 Operation Manual

3.1 IEEE488 Interface

3.1.4 IEEE488 bus commands

To communicate via the IEEE488 bus the standard control signals [MLA], [MTA],
[UNL], [UNT], [ATN], [REN], [SPE], [SPD] are used.
If the control program for the ITC5xx is written in a higher programming language as
e.g. BASIC, then these IEEE488 control signals are automatically transmitted to the
ITC5xx according to the used driver software and do not have to be explicitly
produced in the control program.
Also in the LabVIEW
are implemented.
When receiving the IEEE488 bus commands
[DCL] and [SDC
[LLO] Local Lockout
The command [LLO] will disable the button
operation) will only be possible with the command [GTL] (see below).
[GTL] Go To Local
The command [GTL] will bring the ITC5xx into LOCAL mode (manual operation). The
previously set values for laser current, laser power etc. will no more be valid. The set
values are determined by the main dial knob.
