I am just getting back to this after a few days away. Thank you for the help. I just downloaded the files and I will be studying them. I am sure you will be seeing some progress. Thanks again

Another detail, when you get around to setting up outputs with the 7I71 you should update your EMC2 2.5
to the latest from the buildbot (or pull and recompile if that's how you got EMC2 V 2.5)

There's a bug with SSERIAL bit output when the bit # is greater than 30 (the 7I71 uses bit numbers 0 through 47) This was just fixed yesterday (12/22)

Well I was actually able to get a config that EMC does not reject. I know that does not make it usable but I was surprised when EMC started up using my config. Now I have to figure out how to wire it to the machine.

Ok I have EMC2 started with my config. In the Show Hal Configuration window I can see the resolver and the pwmgen coming off of the hm2_5i23 branch but I can not see the two 7i70 cards and the 7i71 card. I do however have 72 pins of GPIO on the parameter branch. Not knowing exactly what I am looking at yet does this seem right?

To see the 7I70s and 7I71 you will need:

Field power (say 12 to 24VDC) to the 7I70s and 7I71 (yellow light near CPU/jumpers "on")
Cat 5 cables from the 7I44 (say channel 0,1,2) to the 7I70s and 7I71
flat cable from 5I23 P4 to 7I44
a line in the .ini file that enables channels 0,1,2 of the SSERIAL interface like: sserial_port_0=000xxxxx
