GS-2 Spindle Configuration

On to the next issue with my BP mill....
I've been trying to set up serial communications with an Automation Direct GS2 VFD, and I'm not sure what's stopping this from working. I used basically the same custom hal file as the example in the documentation, with a couple modifications to match my setup (I really only got rid of the additional commands, and used the default settings):

# load the user space component for the Automation Direct GS2 VFD's
loadusr -Wn spindle-vfd gs2_vfd -s 2 -n spindle-vfd

# connect the spindle direction pin to the GS2
net gs2-fwd spindle-vfd.spindle-fwd <= motion.spindle-forward

# connect the spindle on pin to the GS2
net gs2-run spindle-vfd.spindle-on <= motion.spindle-on

# connect the GS2 at speed to the motion at speed
net gs2-at-speed motion.spindle-at-speed <= spindle-vfd.at-speed

# connect the spindle RPM to the GS2
net gs2-RPM spindle-vfd.speed-command <= motion.spindle-speed-out

I checked and double checked that my conditions in the GS2 match the custom hal file. One thing that caught my attention was that when I launch my machine after adding the custom hal file, I got an error saying that the motion.spindle-speed-out pin was already linked to a signal. I looked at my machine's hal file, and found it linked to "spindle-cmd". If I comment that line out of the hal file, I don't get an error. Now, when I run the HAL Configuration in Axis, it seems like Axis thinks the VFD is working, but it's not. Any outside ideas?
Thanks

I used the example as a guide and I double checked everything. For transmission errors, we set it up to transmit to a terminal on a second computer, and the inputs seemed to match what was showing up there (it sent no interpretable information, but changed with different inputs). At this point I think I'll reset the VFD to factory settings and start over. I'm still wondering why I had to comment out a line in the original Hal file, but the example did not mention that.
Thanks

This is the line I had to comment out:

#net spindle-cmd <= motion.spindle-speed-out

I reset the GS2 to default settings and started over with the example. I copied it exactly, and changed the settings in the GS2 that I needed to. Still nada. I'm working on checking for transmission errors now

It seems like my issue is related to the run command. The GS2 just will not go into run mode. There are no other spindle nets in the hal file. I'm sure I'm missing something...

I attached my hal file. Maybe a second set of eyes will see something I can't?

The setup we are using has a 4-way serial to USB (so we can see the status of each servo-drive without interupting anything) like this one: www.serialgear.com/4-Port-Serial-USB-CM-41042.html The GS2 is on the 4th Serial port, so that is why it's called out as USB3. We have a serial cable from the VFD to the 4-way.

I will try going straight from the GS2 to my computer, but I don't think that is the issue
