1. Getting Started

1.1 Step 1 - Connecting to Cameras, Monitors, VCR and Mains Supply

Connect the multiplexer to the cameras, monitor(s), VCR and mains supply as illustrated in this
diagram.

Note that an 8-camera multiplexer is used in this example. Other multiplexers differ in the number
and location of the connectors.

Each camera input is provided with two BNC connectors. This allows cameras to be looped­through to other equipment. Either connector may be used for input or output.

Note: This is an example only. Refer to the rear panel labelling for specific locations of connectors.
Desktop models do not have loop-through.

1.2 Step 2 - Step Cable

If a step cable is required, connect it between the multiplexer and the VCR as in the diagram above.
Refer to section 3.1 and section 3.2 for details.

1.3 Step 3 - Alarms

If alarms are required, connect these in accordance with the details in section 3.5.

1.4 Step 4 - Identification of Switches

Identify where the switches are on the underside of the multiplexer as illustrated in this diagram.

A 20-camera multiplexer is used in this example. Other models are similar but have fewer
termination switches.

1.5 Step 5 - Time-Lapse Mode Swi t ch ( S1)

Set this switch to suit the time lapse mode of the VCR or to specify whether a step cable is being
used. For example, set to position 4 for 24 time-lapse operation without a step cable. Refer to
section 3.1 and section 3.2 for details.

1.6 Step 6 - Set-up Options Switch (S2)

Set this switch to specify the basic set-up options. In most installations, the default setting of all
sections OFF, will be required. Refer to section 3.3 for details.

1.7 Step 7 - Camera Termination Switches (S3, S4, S5, S6 and S7)

Set these switches ON if camera termination is required. In most installations the default setting of
all sections ON will be required. Refer to section 3.4 for details.

1.8 Step 8 - SET key options

Further options are available by using the SET key in combination with other keys. In many cases it
is not necessary to access these facilities. Refer to section 4 for details.
