I use three DMM6500 instruments to measure signals from inclinometers [X/Y/Z].
A 4th DMM6510 (scanning DVM 20ch) i use to measure auxiliary signals, excitation and temperatures of the sensors.
These inclinometers are fixed to a rotating table.
I can position the rotating stage within +/- 0.001°.
The setup is used to calibrate the sensors.
I want to start a measurement with the 3 6500's with a LAN trigger.
The problem is that I don't know how to setup a trigger and how to initiate a LAN trigger from LV.
I think i have setup the 6500's trigger table correctly:
- 6500[X] wait for LAN-trigger ; set trigger output [BNC] ; measure the voltage in buffer (Sensor X)
- 6500[Y] wait for Input trigger[BNC] ; set trigger output [BNC] ; measure the voltage in buffer (Sensor Y)
- 6500[Z] wait for Input trigger[BNC] ; set trigger output [BNC] ; measure the voltage in buffer (Sensor Z)
- The scanning DAQ6510 is measured separately [no timing issues].
Has anyone experience with the LAN trigger from LV to the instruments?

I went through the Model DMM6500 6½-Digit Multimeter User’s Manual
It does not mention anything about LAN trigger, but only triggers with RS-232 and TSP-LINK

In the Trigger configuration menu, it is possible to program, in a wait block, an analog input [BNC] or digital Input [if installed] or a LAN Trigger 1-6.
It is really there, but I can't find it in the manual or in the driver vi's ........

TSP LINK uses LAN, so maybe it is talking about using TSP LINK trigger and not really "LAN" and it is applicable only in a multi-instrument use case and not send trigger from your computer to the instrument.

If the instrument is SCPI and IEEE-488.2 compliant then it should respond to the the IEEE common command *TRG to trigger a measurement.
There will be be other commands you need to configure and arm the trigger, hopefully the manual has a section that covers the trigger subsystem and explains the SCPI commands necessary.
