mesa daughter cards config (hopefully)

i have a 7i37ta, and a 7i37-com daughter card connected to a 5i22-1.5 fpga card
i also have a 7i44, and several other sserial cards connected, as well as a 7i47 used for interfacing to servo encoders.
its an odd setup, but i had to make do with what was available -covid/chip shortages etc.
now, the two 7i37 cards dont seem to respond, they could be doa's, ive used several 50pin working cables, they are powered from the same 5v line that powers the other 2 cards(that are working) do i have to initialize them in hal? is there something im missing.
theres no lights on either of the 7i37 cards lit up. and yes, the jumpers are set for external power.
i believe the 24v wiring is right, but unfortunatly cant take a picture till monday. i havent done any testing with the 7i37ta only the -com card. using the machine config display -yellow/red led setting pins etc.

The 7I37s have no LEDs (except red LEDs that indicate reversed inputs)
You do have to set the top 8 GPIOs of each 7I37 I/O connector or to
output mode and inverted

I've been searching for this, what do I put in hal for any of these 8 outputs to work? Just a simple one line example is all I need.

Note that for a 7I37 on the first connector, it would be:

setp hm2_5i22.0.gpio.016.is_output 1
setp hm2_5i22.0.gpio.016.invert_output 1
setp hm2_5i22.0.gpio.017.is_output 1
setp hm2_5i22.0.gpio.017.invert_output 1
setp hm2_5i22.0.gpio.018.is_output 1
setp hm2_5i22.0.gpio.018.invert_output 1
setp hm2_5i22.0.gpio.019.is_output 1
setp hm2_5i22.0.gpio.019.invert_output 1
setp hm2_5i22.0.gpio.020.is_output 1
setp hm2_5i22.0.gpio.020.invert_output 1
setp hm2_5i22.0.gpio.021.is_output 1
setp hm2_5i22.0.gpio.021.invert_output 1
setp hm2_5i22.0.gpio.022.is_output 1
setp hm2_5i22.0.gpio.022.invert_output 1
setp hm2_5i22.0.gpio.023.is_output 1
setp hm2_5i22.0.gpio.023.invert_output 1


For 7I37s on other connectors, same except GPIO bits:

40..47 on the second
64..71 on the third
88..95 on the forth

Thanks heaps for the info. All working good now. I remembered something about this, but it was over 13years ago when I last worked with a 5i25 card. Also I geuss most people now use serial or Ethernet cards so searches don't return much on the 50pin daughter cards.
