MULTIPLE-MONITOR Installation

Refer to Figure 2 and Table A for the following instructions.

1.Connect a 75-ohm video cable from the video source, such as a camera, to the BNC connector labeled VIDEO IN (or INPUT) on the back of the first monitor.

2.Connect a 75-ohm video cable from the VIDEO OUT (or OUTPUT) connector on the back of the first monitor to the VIDEO IN (or INPUT) connector on the second monitor.

3.If you are using a third monitor, connect a 75-ohm video cable from the VIDEO OUT (or OUTPUT) connector on the back of the second monitor to the VIDEO IN (or INPUT) connector on the third monitor.

NOTE: In multiple-monitor installations, a maximum of three monitors can be connected together.

4.Set the impedance switch on the first monitor to HI.

If you are only using two monitors, set the impedance switch on the second monitor to LO (75 ohms).

If you are using three monitors, set the impedance switch on the second monitor to HI and on the third monitor to LO (75 ohms).

5.Plug in the appropriate power cords for the monitors.
