For use in Integras not equipped with the cooling option - setting this option will configure the connection to be an analog
input for 2 or 4 Channel Select Mode. If Channel Select 2 is NOT selected, this input and Channel Select 2 input selects
between Channels 1, 2, 3 and 4. A low level (logic 0) is a voltage less than the Channel Select Voltage and a high level (logic
1) is a voltage greater than the Channel Select Voltage. The Channel Select Voltage is selected on the Radio Tab. For 2
Channel Select Mode, see Table 7 "4 Channel Select Mode".
Note: If configured as a Digital Output, the open-collector transistor requires an external pull-up (i.e., resistor) to a voltage
of 2 to 10 volts.
