4.2.14. Recording Control Unit NDV-1800/1850 – GPS Switch/RADAR Switch
When the RCU is connected to either the GPS Switch or the RADAR Switch, it receives dry contact
feedback signals from the switch. These signals enable the RCU to display which of the GPS or the
RADAR devices is connected to it.
These select input ports can use general dry contact input ports when these ports not use as GPS (or
RADAR) signal select input ports.
