3.1 IEEE488 Interface
ITC500 / page 60
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
®
- or LabWindows/CVI
®
-drivers from
Thorlabs
these functions
are implemented.
When receiving the IEEE488 bus commands
[GET], [LLO], [GTL],
[DCL] and [SDC
] the ITC5xx will execute the following functions:
[LLO]
Local
Lockout
The command [LLO] will disable the button
. Return to LOCAL mode (manual
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.
