VistaCNC iMach P1A Pendant Step Mode

Hi everyone,
I was a long time user of Mach3 and just switched to LinuxCNC. Install and setup was easy. Everything is working except for step mode on my pendant. When the "S/V" mode is selected, it is supposed to go in step mode where the selected jog amount on the UI is issued with each manually generated pulse from the pendant wheel. Nothing is happening. I'm running 2.8.1 and the pendant firmware has been flashed for use with LinuxCNC. Installed the P1A driver without any issues as well. I've experienced this on both 2.7 and 2.8.1. Just wondering if anyone has any suggestions or comments. I'm asking here because I've contacted VistaCNC and have had no response. Thanks.

I have a P4S and step mode work so I would think yours should too.

I see these settings in my vc-p4s.hal. Do you have something like this? Its the only thing I remember seeing that is specific to the step size.

6. Step size selection is defined in vc-p4s.hal. To change or add step size, open and edit the
numbers (in bold font) in vc-p4s.hal file.
