0 0 0 0 on the pins is ch 1 so you get 16 channels with 4 bits, theres no way to program a M216 to power up on ch 1 in the RSS. Home revert is a later feature in the CM & CDM series and you need to use the ignition sense to turn those on/off to reliably get it to work. Sometimes it works by resetting power, but I've had problems in some vehicles if it gets in a brown out condition on boot (engine crank). 

If you program one pin to "channel steer 1" (LSB) and momentarily pull it low the radio should go to channel one. 

If you want to steer up to 8 channels then you need 3 bits and pull all 3 to ground momentarily after bootup. Externally a time delayed one shot relay would do it, use diodes to isolate each input.

Skyler, 

Channel steering should give you 15 channels using 4 pins for steering.  I know the CDM and the GM300's work this way.

AllStar Remote base wise, I am using some radius radios (m216 for VHF,
SM120 UHF). The VHF one does have Channel steer option on the software, but
I don't get to use every channel that the radio has :( only 8 instead of
16. With the amount of repeaters here in Denver , I need as many channels
as I can get!

I can easily simulate key presses, but I would like a reliable way to reset
the channel back to original state. These radius radios remember the
channel they were on after a power cycle (unfortunately, in my case). Is
there any way to force it to go back to channel one?

73,
