I found the pin out on the back of the Orion but there are 2 pins that don’t coincide with the Arduino, on port 1 and 2 there is a pin V-M and on port 5 there is a pin DTL what are these pins for?

@wildwingman, V-M is the power positive pole of Port 1, and Port2. There is no DTL pin on Port 5, its DTR, its a pin for bluetooth to reset MCC. Each time, when you reset, you can see a blue light flash, its done by DTR.
