Digital inputs

Using the Inputs tab (see

, you can configure up to 10 digital inputs that 

allow you to remotely control various operational characteristics of the transmitter. Unless otherwise 
noted, these inputs are only accepted by the transmitter if the remote/local status is set to remote.
