I moved w1 to the left hand position. a red led came on and when i try to start the a configuration in linuxcnc, the error changes to
./test6.hal : 87 : pin 'hm2_5i25.0.7i76.0.3.input-01' does not exist

That likely means that either

1. There is a power issue on the 7I76
2. You dont have the right firmware (7I77_7I76) loaded
3. The sserial ports (3 and 4) on the 7I76 connector are not enabled in hal

On the 7i76e i have 5v to p3 and 24v+ to pin 1 of the orange connector and - to pin 8 like the 7i77. i moved w1 as you suggested for the 7i77 bot didn't change anything on 7i76 there is no red led on the 7i76 the other 2 boards now have the red light.
the firm ware was set to 7i77_7i76. the hal not sure. going through the pnc.config the 7i76 goes to ss3 itself

The 7I76 has no red LED

What does:

sudo mesaflash --device 5i25 --readhmid

report?

ok i altered a config to use mesa 1 paraport and that makes sense except for it doesn't match how im set up.. I have 5i25 with 7i77 in the p3 port and a 7i76e in the p2 port and the 7i64 attached to the 7i77.
If the pnc.config is wanting my to put the 7i77 on mesa card 0 as it seems to want, and the 7i76 on mesa card 2 both with there own firmwares then i don't have the firmware that i need. i would need for mesa card 0 firmware for 7i77-7i64, and in mesa card 1 i would need firmware for just 7i76e. am i correct in thinking this. up to know i have been trying to do it with just mesa card 0 and 7i77-7i76 firmware and putting 7i64 on channel 2 on i/o connector 3, but im unable to connect to the 7i76. the 7i64 and 7i77 seems to connect if i use a simple enough config to not get an error. Any insite to the path to take here would help.

Setting up a parallel port is unrelated to your issue.

To check that you have correct firmware installed, what is the result of the command:

sudo mesaflash --device 5i25 --readhmid

OK that's a 7I77x2 configuration, not a 7I77_7I76 configuration

To install the correct firmware, you would:

1. fetch 5i25.zip from mesa
2. unzip 5i25.zip in you home directory
3. cd to ~/configs/hostmot2/
4. issue this command:

sudo mesaflash --device 5i25 --write 5i25_7i77_7i76.bit --reload

Ok, I reflashed the 5i25 (its acturally a 6i25 but everyone says they are same thing)
I still get the same error so I have to assume I have the 7i76 connected wrong. on the 5i25 card i have another db25 plugged in through the 26 pin connector p2. should i have used the eithernet serial and plugged the 76 to the 77 then the 64 to the 76 like a daisy chain. when i do pnc.config. i only mesa card 0 not mesa card 1 that i assume is for the p2 connector.

The 7I76 should connect to P2

You may still have a power issue or the 7I76 sserial ports may
not be enabled in the hal file

Can you copy/paste the line at the beginning of the hal file that starts with
"loadrt hm2_pci" to the forum?
