Looking through the various Elk M1 installation manuals, I'm finding conflicting device types for serial devices. In particular,
type 1 = keypad K1P1, K1P2, KPAS
type 2 = input M1XIN
type 3 = output M1XOV, M1XOVR
type 4 = serial M1XSP, M1XRF
type 5 = radio? M1XZW
Note that M1XRF is not type 5!
- the manual for M1ZXW indicates it is a type-5 device, along with other serial devices
- the M1XSP and M1XRF manual says that they are type-4 devices
type 1 = keypad K1P1, K1P2, KPAS
type 2 = input M1XIN
type 3 = output M1XOV, M1XOVR
type 4 = serial M1XSP, M1XRF
type 5 = radio? M1XZW
Note that M1XRF is not type 5!
