RFD900 Tools vs MP

Tinkering with some new RFD900Xv2 radios. Since they are new I wanted to see if a firmware update was needed so I checked with RFD 900 Tools.

Then as the day went on I went in again in Mission Planner.

I noticed that the Max Window setting in RFD Tools is 131ms, and the same radio in MP says 20ms. I double checked and each time RFD says 131, and MP says 20.

I’m going to assume that RFD Tools is correct, but I’m curious if anyone else has noticed differences between the two tools or if there’s any bigger issue here?
