The switch is a DiSEqC 1.0 not 2.0 version.

DiSEqC 2.0 is a new standard for switches where the switch and receiver communicate with each other (2 way communication). DiSEqC 1.0 is a 1-way communication (receiver send a signal to the switch only).

Since you are only using 3 out of the 4 inputs, you might want to use a terminal plug on the unused # 4 input.
