Figure 2. Connecting VCR to Multiplexer

Figure 2 shows how to connect the VCR to an MX4000 Series Genex® Multiplexer.
•For Automatic Speed Tracking (“B” lines in Figure 2)
This lets the VCR control the multiplexer’s recording speed. It is the most efficient
recording method.
1. Connect the VCR’s CLK output to the multiplexer’s head switching (HS) input to
synchronize camera switching.
2. Connect the multiplexer’s ground terminal to the VCR’s GND terminal.
•For Alarm Recording (“A” lines in Figure 2)
This is to start and stop recording when there are alarms.
1. Connect the multiplexer’s normally open (NO) relay terminal to the VCR’s ALM IN
(alarm input) terminal.
2. Connect the common (C) terminal to the VCR’s GND terminal.
NOTE:

Cameras and

monitors are connected to

the multiplexer. Figure 2

shows the connection

between the VCR and an

MX4000 Series Genex Mul-

tiplexer. Refer to the multi-

plexer manual for additional

component connections.
