Hello!

I'm trying to start configuring set of Mesa cards for this retrofiting:
linuxcnc.org/hardy/hardy/emc2/emc2/index...ve-tool?limitstart=0

Now on my table:

5i25 (with two smart-serial ports)
=>7i77 (5 encoders + 5 axis + 1 spindle out + inputs and outputs) => 7i64 (inputs and outputs)
=>7i77 (1 spindle out + inputs and outputs)


Then i'm starting LinuxCNC i can't see any IO hal pins like hm2_5i25.0.7i77.0.0.input-00 for one 7i77-car and hm2_5i25.0.7i77.1.0.input-00 for another.

And also how can i set up 7i64 on RS-422 to see it's IO pins in HAL??

Here is my HAL-file (just for start) and dmesg out - what am i doing wrong?

Warning: Spoiler!

For the digital I/O parts of the 7I77 I/O to work requires that field power be present when the interface is started
Therefore you must have the 12 or 24V field power connected to TB2 (Yellow LED CR3 should be on)

In your hal file you have "num_pwmgens=7" this should be removed as there are no pwmgens in 7I77 configs

It works:

1. 5i25 change two jumpers (W1-UP and W2-UP) to put supply +5V in cables to power up both 7i77
2. 7i77 (both) provide +12V to VFIELD tab TB2 (pin 1 and pin 8) - from external power source.
3. 7i64 make jumper W2-DOWN (W1-UP, W2-DOWN, W1-UP for exactly 2.5 MBAUD for SSerial),
and W9-DOWN (but i'm not sure it's necessary)


In your hal file you have "num_pwmgens=7" this should be removed as there are no pwmgens in 7I77 configs


Thats right!

Thank you for help! :)
