Installation 3-3
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 to:
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
CAUTION!
To avoid possible damage to the OM 1000, ensure that the ac-power cord is disconnected before connecting any I/O
cables.
Connecting Ethernet and Modulator Output Cables
For most applications, the RF modulator must be connected to the distribution system. Figure
3-2 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:
