2.2 Connection
2.2.1 Connecting to Keyboard Controller (Optional)
The optional peripheral (keyboard controller) allows you to accurately control the pan / tilt / zoom movement for a
speed dome camera with the convenient 3D joystick and functional keypad design.
Note: It’s highly recommended to purchase this device to work with your speed dome camera for
accurate control.
The following connection illustration is an example. For detailed connection and operation guide, please refer to
your keyboard controller manual.
Rear panel of the keyboard controller:
DC 12V AUDIO LAN EXTERNAL I/O DVR P.T.Z
RJ11 cable
RS485-A and RS485-B wires
of the speed dome camera
RS485-A: Red wire RS485-A: Brown wire
RS485-B: Green wire RS485-B: Orange wire
The RJ11 cable is not supplied in the sales package.
STEP 1: Get a RJ11 cable with the proper length to your connection.
Different RJ11 connector may have different wire layout, so the connection might be different. If you
cannot control the speed dome camera after connection, please reverse the RJ11 cable connection with
the speed dome camera.
STEP 2: Remove one end of the insulating coating of the RJ11 cable.
Remove one end of the insulating coating of the RJ11 cable to find the RS485-A and the RS485-B wires,
and remove the insulating coating to reveal the naked wires for further connection.
STEP 3: Twist the RS485-A and RS485-B wires together.
Twist the RS485-A (red) and RS485-B (green) wires of the RJ11 cable to the RS485-A (brown) and
RS485-B (orange) wires of the speed dome camera (as shown in the picture above). To protect the
naked wires, use the insulation tape to cover on the twisted wires.
STEP 4: Connect the RJ11 connector to the “P.T.Z” port on the rear panel of the keyboard controller.
