Connecting The Interface Cables; Connecting Ethernet And Modulator Output Cables - Motorola OM 2000 Installation & Operation Manual

3 INSTALLATION

Connecting the Interface Cables

The following standard cabling is required:
•
The Ethernet interface to the headend LAN
•
RF or IF output to the distribution system
Depending on your site configuration, you may need additional cabling:
•
The RS-232 DB9 interface to the serial data source or destination device
•
The DB25 interfaces, either RS-232 or RS-530, to the serial data source or
destination device
•
Optional ground wire connection; refer to
stud
Caution!

Connecting Ethernet and Modulator Output Cables

For most applications, the RF modulator must be connected to the distribution
system. Figure 3-1 illustrates a typical connection for Ethernet and modulator output.
In the illustration, the IF output is connected to a C6U; however, other upconverters
can be used:

To connect the Ethernet and RF-modulator output cables:
•
Connect the Ethernet cable to the rear-panel connector marked
•
Connect the RF combiner to the rear-panel connector marked
standard coaxial cable with F-type connectors.
•
Connect the upconverter to the
with F-type connectors.
