Hi Josh:
I am using NI-VISA drivers, but I wanted to map the MXI triggers and TRIG-IN and out from software calls. I started looking at the following documents:
VXI-MXI-2 users manual: http://www.ni.com/pdf/manuals/321003b.pdf (chapter 5)
Specifically registers: VTCR, VUCR, VMCR, VLAR, VTDR, VTMSR, VMTCR
High Level Register access example:
ftp://ftp.ni.com/contrib/epd/B45EACE3DA7056A4E034080020E74861/High_Level_Register_Access_with_NI_VISA.zip
and later I found:
http://www.ni.com/pdf/manuals/370132c.pdf
But I was concerned about the "Note" on page 5-63 (253 of 423) Since the registers only enable and have a direction, this seems to indicate I could map multiple signals to TRIG-IN or TRIG-OUT, but never bot
h at the same time.
I am in the process of writing some test code. I might attempt the TRIG-IN/TRIG-OUT from the VISA call, but this still leaves me wondering how to map the MXI trigger lines without using a GUI.
