How do I read more than 8 channels from an AMUX board using DASYLAb

[UNSW Mining]

I am trying to use DasyLab to read data from a PCI-6034E connected to an AMUX 64T board to which is connected three SG Strain Gauge modules.

I've used NI-DAQ to configure the DAQ card (differential, AMUX (1)). However in DasyLab I can only configire only up to a maximum of 8 channels. How do I use the multplexing capability of the AMUX to read 32 differential channels?

In testing using NI-DAQ, four traces were graphed for each of the 8 channels so it would seem the PCI card understands it is connected to a multiplexing board.

Also what do 1, 2 & 4 mean in the context of AMUX64(1), AMUX(2) and AMUX(4) which appears in the configuration options of NI-DAQ?

Thanks

Attached is some information for an older version of DASYLab with the AMUX64T. The bottom line was that we do not support it, but we figured out how to manually de-mux the channels.

The ideal, untested solution would be to define the AMUX as an acessory for the board, using the Measurement and Automation Explorer (MAX), and then to define a virtual channel to reference individual channels on the AMUX. This is untested. Right now I don't have a board to check the possibilities (I'm on vacation on the road), but it should be easy enough to try.

We do not claim support for the AMUX, and never have. However, I have one customer who does use it, but is using an older version of DASYLab with the "old" driver.

Good luck - let us know if
this helps.
