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 status 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 process- ing (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 uninter- ruptible power system (UPS). Then, the power supply to the recorder can be suspended.
