CONTROL PORTS
The HA82-3 can be ordered with a GPIO or RS-232 Control Port.
GPIO
The GPIO version defaults to Input #2 when no cable is attached (internal
pull-up resistor to 3.3V). When the SIGNAL line is sent logic 0 or shorted to
ground with a switch, the HA82-3 input is switched to Input #1. It will remain
there until the low signal is removed. It does not latch.
