9.2.3 Momentary Discrete Inputs, measurement option code 32
and 42 (702DX32, 702DX42)
The 702 transmitter is capable of measuring momentary discrete inputs of 10 millisecond or
more in duration, regardless of the wireless update rate. At each wireless update, the device
reports current discrete input state and an accumulating count of close-open cycles for each
input channel.
