Connecting the interface Cables
The following standard cabling is required:
• T h e E t h e r n e t i n t e r f a c e t o t h e h e a d e n d L A N
• RF or IF output to the distribution system
Depending on your site configuration, you may need additional cabling:
• T h e R S - 2 3 2 D B 9 i n t e r f a c e t o t h e s e r i a l d a t a s o u r c e o r d e s t i n a t i o n d e v i c e
• The DB25 interfaces, either RS-232 or RS-530, to the serial data source or
d e s t i n a t i o n d e v i c e
• Optional ground wire connection; refer to Figure 2-7 for location of grounding

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

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