Making the Overhead Connection
Connect the Overhead output to the site’s overhead system input/amplifier using a male-to-male RCA
patch cord. The Overhead output can drive several hundred feet of low capacitance wiring if necessary.
Making the Phone Line/Modem connection
The system requires a phone line connection for proper operation. The system is equipped with either
an internal modem, or an external USB modem. All that is required is to connect the modem to an analog
phone line. The system is configured at the factory with a default dial-string that should work in most
situations. If the system does not successfully connect, please send the addendum for instruction on adjusting
the dial-string for proper call origination.
DSL Filter Installation (Only required if site has DSL)
If the phone line is a DSL or ADSL then, a DSL/ADSL filter must be installed for proper
system/modem operation. A filter can be installed as pictured below. If the line is filtered elsewhere, prior to
connection to the system, then no additional filter need be installed.
