and then enter the relevant data in the quick install menu.

2.1

Connections

Primary connections

1. Connect the cameras to the BNC camera input

connectors. (Set impedence to Hi-Z only when the video

loop-through outputs are used.)

> The DVR4C automatically configures itself as a PAL or

NTSC unit by detecting the signal format of the first

connected camera (lowest camera input number).

2. Connect a monitor to the BNC output MON Out.

> Connect the unit to the monitor using 75-ohm video

coaxial cables with BNC connectors.

Optional connections

3. Connect up to four audio inputs via the RCA connectors.

4. Connect an audio output device via the RCA connector.

5. Connect up to four (alarm) inputs via the terminal

connector.

> Each input line can be switched by a relay contact from

devices such as pressure pads, passive infra-red

detectors, smoke detectors and similar devices. You can

configure the alarm inputs as N/O or N/C in the menu

system. The default is N/O.

6. Connect up to four alarm output relays via the terminal

connector.

> Relay 1 responds to an input alarm, Relay 2 responds to a

system failure and the other relays are assigned to the

remote software. Configure the alarm outputs as N/O or

N/C in the menu system.

7. Connect to your network via the Ethernet port.

> The DVR4C is delivered with the DHCP function switched

on, so IP addresses are assigned automatically if the

network server uses DHCP. (Refer to the System

settings/Connectivity/Network setup menu.)

8. Use the RS232 connector to connect to a PSTN line.

> The serial RS232 console port connector is used to

connect a PSTN modem or a text device to the unit. Use a

null-modem cable to connect the serial port of the external

equipment to the unit. The Baud rate can be selected in

the menu system.

Powering up

9. Switch on all connected equipment.

10. Connect the power cord to the unit and switch on.
