Preparation (Step 1 Connection/Installation)

Ⅲ DC 12 V or AC 24 V Input power cable
Connect the DC 12 V or the AC 24 V power
supply to the DC 12 V/AC 24 V terminals on
the terminal board. To prevent connection er-
rors or a cable disconnection, we recommend
the use of lug plates for the connections.
The following table shows the connection dis-
tances and connection cables provided that 2-
conductor VVF cables (vinyl-insulated vinyl
sheath cables) are used.

Be careful of the following items when connecting the cables.
• Turn OFF the power supply to all components before making connections.

Note

Connecting multiple VN-C205 Cameras
In a system where more than 1 VN-C205 is used, turn on the power for a VN-C205 first, followed
by setting the camera until "2-3 Setting IP Address for this Camera Using the 'VN-C205U Setup
Tool' " is completed. Upon doing so, turn on a second camera and perform setting in the same
way. Perform the same procedure for subsequent cameras.
• Default IP address setting for all VN-C205 cameras is 198.168.0.2. When the power for multiple

cameras are turned on at one time under a single LAN environment, therefore, proper access
may not be established due to IP address redundancy. Do not turn on the power of more than
1 camera at the same time.

• When IP address redundancy occurs, ensure that only one VN-C205 exists under a single

LAN environment, and wait for some time (at least 10 minutes). In some cases, the power for
all network devices under the same LAN environment may have to be turned off and on again
to enable access to VN-C205.

Cautions

• If thin cables are used (i.e. with a high resistance), a significant voltage drop will occur when

the unit is at its maximum power consumption. Either use a thick cable to restrict the voltage
drop at the camera side to below 10%, or place the power supply near to the camera. If
voltage drop occurs during operation, the performance will be unstable.

• Do not allow input from both a DC 12 V and AC 24 V power supply at the same time.
• When using a DC 12 V power supply, ensure that the polarities of the cable are correct.
• The AC 24 V power supply should conform to the following:

For USA

: Class 2 only

For Europe : Isolated power supply only
