Alarm Input/Output; Network Port; Factory Reset Switch - Eneo DLR-2016/500V Operating Instructions Manual

Alarm Input/Output

AI 1 to 16 (Alarm-In): You can use external devices to signal the DVR to react to events. Mechanical or electrical
switches can be wired to the AI (Alarm-In) and GND (Ground) connectors. The threshold voltage of electrical switches
for NC (Normally Closed) is above 2.4V and for NO (Normally Open) is below 0.3V, and should be stable at least 0.5
seconds to be detected. The voltage range of alarm input is from 0V to 5V. See Chapter 3 ─ Configuration for
configuring alarm input.
GND (Ground): Connect the ground side of the Alarm input and/or alarm output to the GND connector.
NOTE: All the connectors marked GND are common.
NO (Normally Open): Connect the device to the COM and NO (Normally Open) connector. NO is a relay output
which sinks 1A@30VDC (NO). See Chapter 3 ─ Configuration for configuring alarm output.
Connector Pin Outs:

Network Port

The DVR can be networked using the 10/100Mb Ethernet connector. Connect a Cat5 cable with an RJ-45
jack to the DVR connector. The DVR can be networked with a computer for remote monitoring, searching,
configuration and software upgrades. See Chapter 3 ─ Configuration for configuring the Ethernet
connections.
CAUTION: The network connector is not designed to be connected directly with cable or wire
intended for outdoor use.

Factory Reset Switch

The DVR has a Factory Reset switch to the right of the VGA connector on the rear panel.
This switch will only be used on the rare occasions that you want to return all the settings to
the original factory settings.
CAUTION: When using the Factory Reset, you will lose any settings you have saved.
To reset the unit, you will need a straightened paperclip:
1. Turn the DVR off.
2. Turn it on again.
3. While the DVR is initializing, the front panel LEDs will blink. When the front panel LEDs blink, poke the
straightened paperclip into the unlabeled hole to the right of the VGA connector.
4. Hold the switch until all the LEDs on the front panel are lit.
NOTE: When the DVR successfully resets to factory defaults all the LEDs on the front panel flash five times.
5. Release the reset switch. All of the DVR's settings are now at the original settings it had when it left the factory.
CAUTION: Ensure the DVR is not near any heat source that could cause overheating.
Your DVR is now ready to operate. Refer to Chapter 3 ─ Configuration and Chapter 4 ─ Operation.
NOTE: To make connections on the Alarm Connector Strip, press and hold the
button and insert the wire in the hole below the button. After releasing the
button, tug gently on the wire to make certain it is connected. To disconnect
a wire, press and hold the button above the wire and pull out the wire.
