MX4000 GENEX™ SERIES MULTIPLEXER
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 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 (N.O.) 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 moni-
tors are connected to the
multiplexer. Figure 2
shows
the connection between the
VCR and an MX4000 Series
Genex Multiplexer. Refer to
the multiplexer manual for
additional component
connections.
