Video Out
NOTE: The VGA and Video Out (BNC) connectors may be connected to individual monitors for simultaneous
operation.
Audio In/Out
NOTE: It is the user’s responsibility to determine if local laws and regulations permit recording audio.
The DVR does not have amplified audio output, so you will need a speaker with an amplifier. The DVR
does not have a pre-amplifier for audio input, so the audio input should be from an amplified source, not
directly from a microphone.
Power Cord Connector
WARNING: ROUTE POWER CORDS SO THAT THEY ARE NOT A TRIPPING HAZARD. MAKE
CERTAIN THE POWER CORD WILL NOT BE PINCHED OR ABRADED BY FURNITURE.
DO NOT INSTALL POWER CORDS UNDER RUGS OR CARPET.
THE POWER CORD HAS A GROUNDING PIN. IF YOUR POWER OUTLET DOES NOT
HAVE A GROUNDING PIN RECEPTACLE, DO NOT MODIFY THE PLUG. DO NOT
OVERLOAD THE CIRCUIT BY PLUGGING TOO MANY DEVICES IN TO ONE CIRCUIT.

Connect the main monitor to the Video Out connector.
A VGA connector is provided so that you can use a standard, multi-sync computer monitor as your
main monitor. Use the cable supplied with your monitor to connect it to the DVR.
Your DVR can record audio from up to four sources. Connect the audio sources to Audio In 1,
Audio In 2, Audio In 3 and Audio In 4 as needed using RCA jacks. Connect Audio Out to your
amplifier.
Connect the connector of the adaptor to the DVR, and connect the AC power cord to the adaptor and then
to the wall outlet.
An RS232 port is provided to connect remote control devices such as a control keyboard. PTZ cameras
or text-in devices can also be connected to the RS232 port. See Chapter 3 ─ Configuration and the PTZ
camera, text-in device or remote controller manufacturer’s manual for configuring the RS232 connection.
