3.5.7 UPS Configuration
Connect the UPS to the NVR’s DI/DO port for sending and receiving
signals between the UPS and the NVR. Refer to the diagram below to
connect the UPS with its RS-232 interface to the NVR’s DI/DO port.
The NVR can receive signal from the UPS when there is a power fail-
ure and shut down itself automatically within a period of time.
Connect UPS with its RS-232 interface to the NVR’s IO port:
* The NVR uses DI_1 to receive signal from UPS system and uses DO_1 to
shut it down.
