second daughter board on 5i25 won't communicate

I am trying to use the P2 connector on 5i25 but it will not communicate when I start up .( the red fault light

stays on )

I have a 7i85 on P3 of 5i25, which works fine, and am trying to use a second 7i85 on the P2 connector .


Debug file information:
spindle.hal:108: Pin 'hm2_5i25.0.7i83.1.0.analogena0' does not exist

It finds the board OK when I do a halrun session.

halcmd: loadrt hostmot2
halcmd: loadrt hm2_pci
halcmd: show pin
Component Pins:
Owner Type Dir Value Name
5 bit IN FALSE hm2_5i25.0.7i83.1.0.analogena0


I have tried a number of different config strings in the ini file, but it has made no difference.




[HOSTMOT2]
DRIVER=hm2_pci
BOARD=5i25
CONFIG="num_encoders=4 sserial_port_0=02000xxx"
CONFIG="num_encoders=4 sserial_port_0=00000xxx"
CONFIG="num_encoders=8 sserial_port_0=00000000"
CONFIG="num_encoders=-1 sserial_port_0=00000000"

do you have the correct firmware on the 5i25? to be able to use 2 7i85 boards?

Thanks for the response. The firmware is 7i85x2 so it looks like it should work.

Show pin lists number 0 thru 7 encoders. I presume that means hostmot2 has found both 7i85 boards.

your error is 'hm2_5i25.0.7i83.1.0.analogena0' does not exist

do you have any 7i83?

I got it working now! I do have a 7i83 connected to 7i85.

the config string was wrong.

The second 7i85 is sserial_ port=1


CONFIG="num_encoders=-1 sserial_port_0=00000000 num_encoders=-1 sserial_port_1=00000000"

This should enable everything. I will x out the sserial ports that I am not using later.
