CONNECTING GENEX MULTIPLEXERS
Use COM 4 to connect up to eight Genex Multiplexers to the CM6800.
1. Connect the COM IN port of the multiplexer to COM 4 on the CM6800, using the
6-foot (1.8 m) reversed data cable supplied with the CM6800.
One reversed cable and four straight cables are supplied with the CM6800. Use the
reversed cable for connecting the Genex multiplexer to the CM6800.
A straight data cable is supplied with the Genex multiplexer. Use this cable for
connecting a second Genex multiplexer to the first multiplexer, if necessary.
2. Connect the MAIN monitor output from the multiplexer to any of the 48 camera inputs
on the CM6800.
3. Connect cameras to the multiplexer and then loop them to the CM6800. Refer to the
MX4000 Genex Series Simplex and Duplex Multiplexers Installation/Operation Manual
for detailed camera connection instructions. Terminate the video loop at the CM6800.
4. If required, you can connect a total of eight Genex multiplexers through COM 4. Daisy-
chain the multiplexers by connecting a straight data cable from the COM OUT port on
the first multiplexer to the COM IN port on the second multiplexer; connect the COM
OUT port on the second multiplexer to the COM IN port on the third multiplexer.
Continue to the eighth multiplexer, if necessary.
Refer to the
System Start-Up
section for additional configuration steps required when using
a Genex Multiplexer.
NOTE:
If you do not con-
nect multiplexers to COM 4,
you can connect a
CM9760-MDA or an ASCII
device through COM 4. Us-
ing either device requires a
change in serial port set-
tings. Refer to the
Program-
ming
section.
