● Connection of the control output

When an alarm device such as a buzzer or a lamp is connected, the signal output from pin nos.15 - 18 can be used to notify the sta-

tus by sounding a buzzer or lighting a lamp.

The following example is of a connection with the HDD error output (pin no.16).

● Connection with the Uninterruptible Power System (UPS)

This is an example of a connection with the uninterruptible power system (UPS) to be installed to protect from a power outage.

When a signal is supplied to the outage detection input terminals from the uninterruptible power system (UPS), internal processing

(stops recording safely) will start to shut off the power supply for the recorder.

After completing the internal processing, a signal will be supplied from the outage processing end output terminal to the uninterrupt-

ible power system (UPS).

Then, the power supply to the recorder can be suspended.

Do not use an UPS that provides a square wave. It may damage the recorder.
