5i25 + 2 X 7i74

Ok,

I still have one question how are these cards numbered in hal? Does card number ie. hm2_5i25.0.7i84.2 correspond to channel number on 7i74?

Yes, it does.

There is an option for hosmot2:

loadrt hostmot2 use_serial_numbers=1

That changes the pin names so that you get pins like "hm2_7i84.004F..." where the 004F is the last 4 digits of the card serial number on the sticker.

The means that the order in which you plug in the cables doesn't matter. It's an option that I use myself, but it doesn't help with the "sserial_port_1=302xx" thing, that still depends on the socket that the device is plugged in to.

I ought to add the option to say "sserial_004F=3" too. (it can't be a HAL parameter, by the time HAL has started it is too late to change the board mode)

Yes, ViN must be 8V or greater but VFIELDA and VFIELDB can be 5 to 32V
input thresholds are set to 60% of VFIELD going up and 40% of VFIELD going down
(20% of VFIELD hysteresis)

inputs are safe to 48V continuous and 120V momentary

I probably would have chosen a 7I69 (48 I/O) or 7I90HD (72 I/O) for driving common anode 5V LEDS

Thank you for information. Those would of been better choices. I liked screw terminals on 7i84 because I have limited installation space behind operator panel. So two 7i69 + BOB's might not fit.

For future reference, the M20 connectors are handy for this:

The picture is the 2x2 but they go up to 10x2 and you can fit them side-by-side in the headers.
You need a little crimping tool, and the crimps are bought separately, but they make a neat solution for individual wires to box-headers.

I found a picture of the M20 connector on the 7i73 inside my lathe apron

Hi,

Well that is a good idea I have to remember this one. Thanks. Now I am wondering why my external jog button does not jog axis....
