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

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 128th Multiplexer.

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
