3.3.5 Connecting TCP/IP (Ethernet)
z Connect LAN to ‘ETHERNET’ connector.
3.3.6 Connecting Power
z Connect included power supply to ‘12VDC’ connector. Input voltage of power supply is from 100 VAC ~ 240 VAC.
z It’s suggested not to use ‘SUB’ connector for the product equips with dual ‘12VDC’ connector (MAIN & SUB).
3.3.7 NOTES
1. ‘MON’ Connector: Set impedance switch on the back of monitor to 75 Ω if only the monitor is connected to ‘MON’
connector. Set impedance switch on the back of monitor to HIGH Z (HIGH IMPEDANCE) if monitor is connected to
‘MON’ connector and other units (VCR. etc.) are connected behind to monitor. The last unit always has to be set to 75
Ω.
2. ‘VIDEO-IN’ Connectors: It is not necessary to set 75
Ω if you are connecting cameras to connectors in upper row only.
You cannot connect cameras to lower row connectors.
3. ‘VIDEO-OUT’ Connector: If there are other units are connected to ‘VIDEO-OUT’, impedance of the last unit always has to
be set to 75
Ω. Do not connect Camera to ‘VIDEO-OUT’.
4. Any voltage can not be applied to alarm input.
5. To avoid accidental deletion of hard data, please press the MENU key on the front of the DVR before powering off the
unit.
