1.2 External cable connection method
Camera external inlet cables are all connected to
RS485 lightning protection adapter, which is connected
to the camera through a 0.8-meter-long RJ45 cable
with crystal heads at both ends.
Fig 1.1 RS485 lightning protection adapter
K1: RJ45 socket
K2: NC socket
K3: Output and input terminal of RS485
(output and input can be arbitrary selected)
K4: 12VDC input terminal
K5: 12VDC input terminal
JP1: BUS matching resistor of RS485
D4: Status indicator
Power connector
Please carefully check the power supply voltage and
current. The power supply voltage for the camera is
12VDC and the current must be 2A or more. External
power supply should be connected to 12VDC input
terminal (any one of K4 or K5, but can not connect
both at the same time).
RJ45 cable
Connect one end of RJ45 cable (supplied
accessories) to RJ45 socket of the camera and
another end of RJ45 cable to K1 socket.
Video cable
Video signal is transmitted through a coaxial cable
with its BNC plug connecting to K2 socket.
BUS connection of RS485 lightning protection
adapter
Data cable is connected to K3, output terminal is
connected to next device in BUS. Positive pole and
negative pole of data cable are connected to "A" and
"B" terminal respectively.
