Connection with the Uninterrupted Power Supply (UPS)
•
The figure shows an example of how to connect a UPS as protection against power failures.
•
When a power failure detect input is received from the UPS, the disk recorder's power failure process starts to process this
signal to turn off its power supply.
•
When the power failure process is completed, the disk recorder outputs a signal to the UPS.
•
When the UPS receives the completion signal from the disk recorder, the disk recorder's power is turned off
■
Connection with CONTROL output
•
Signal outputs (Pins #1-6, 18) can be used to connect alarm devices such as a buzzer or lamp to inform you of the opera-
tion status by sounding a buzzer or lighting a lamp when a signal is output.
•
The figure below shows an example of how to connect an alarm output (Pin #6) to warn of low remaining HDD capacity.
