Select cameras 1 to 16 by pressing the camera number and then Main. The selected camera will appear in
the full screen mode and is under control if it was dome camera.
Even if no camera is connected to the multiplexer input, the screen will show the camera input (see
following example).
To select first multiplexer under control, press 1 + Mux ( m: ID of Mux – up to 128)successively

16 16+ Main
This sequence (No.+Main) is same as pressing the 1, 2, 3…16 buttons on the multiplexer.
To select second multiplexer under control, press 2 + Mux
when a second multiplexer is connected:

When using two multiplexer configuration, connect the main or spot output of the first multiplexer to the
Camera 16 input of the second multiplexer.
If the spot output of the first multiplexer is connected to the Camera 16 input of the second multiplexer, you
can see selected camera output through the spot output of second multiplexer by pressing camera No. (1 to
31) + Cam Successive camera call is valid on two Mux configuration only.
For example: 1+Cam will switch camera 1 to the second multiplexer spot output and you can control all
functions of the selected camera using the keyboard controller.
If you install more than two Multiplexers, the unit number (ID : up to 128) of the Multiplexer and selection of
the Multiplexer must be the same in order to control the Multiplexer with the Keyboard.
Example: If the unit address (number, see page 15) of the Multiplexer is 128, you should press
128 + Mux to control the 128 th Multiplexer.
Picture on Spot output monitor (Camera No.1~16+Aux1~4)
Pressing Camera No. 1 to16 + Aux1~ 4 will switch the selected camera number to the specific spot monitor
output of the multiplexer. The selected camera can be a dome camera or a standard camera. The Keyboard
controller maintains control of the previously selected dome camera. It does not change the main output of
the multiplexer.
Example: m+Mux, n+AuxN m: ID of Mux, n: input No. of camera, N: spot output No.
1+MUX, 2+Aux1(~4) will switch camera 2 on multiplexer 1 to the spot output of multiplexer 1.
2+MUX, 3+Aux1(~4) will switch camera 3 on multiplexer 2 to spot output of multiplexer 2.
1+Cam will switch camera 1 to the spot output of multiplexer 1 and the keyboard controller has
control of the selected camera.
In a two multiplexer configuration, 18+Cam will switch camera 18 (second camera on Multiplexer
