10. UPS Configurations
The UPS allows the NR-1604 to receive an uninterrupted power supply in the event
of a power failure. Through the UPS, the NR-1604 is able to detect if there is a
power failure and automatically shut itself down after a period of time, ensuring that
the user does not experience an abrupt interruption in their video recording.
To send and receive signals between the UPS and the NR-1604, connect the UPS
to the NR-1604 using the DI/DO port. Refer to the diagram below to connect the
UPS’s RS-232 interface to the NR-1604 DI/DO port. Note: the NR-1604 will use
D1-1 to receive signal from the UPS system and DO-2 to shut down.
