I have several questions regarding the PCI-1422.

[Ryan S.]

1. What pins are the RTSI lines (0-6) listed in the IMAQ manual?

2. What are common causes of the General Exhausted Resource error IMG_ERR_MXRC, which we get about every 3rd time we run our vi?

3. How do you select the Trigger direction (In/Out) as described on pg. 3-3 of the PCI-1422 User Manual?

4. Many of the data lines (not quite all) are driven to 5V. Why is this? Why not LVDS neutral 1.2V, or maybe 1.4V or 0.9V (high/low)?

5. My control/clk/enable lines are also driven to 5V. Why not LVDS voltages?

6. Using IMAQ Generate Pulse.vi and IMAQ Trigger Read.vi, I can get the software to acknowledge a pulse generation and reception, however when monitoring the trigger with a scope I see
nothing. Suggestions?

I am using IMG0.icd as a default.

Thank You for any help.

After verifying shorted current draws, it appears that the triggers simply float high, sourcing less than 10uA, however the data lines still appear to be driven with a slightly higher 40uA current source.
