NSTALLATIONS

The sections that follow show some typical installations to aid you in connect-
ing your system. Specific instructions for mounting and connecting various
sensors and components are contained in the manuals for those components.

WeatherLink with Short-Range Modem Pair

The illustration below shows a WeatherLink connection via our Short-Range
Modem Pair (SRM Pair). The WeatherLink cable plugs into the Short-Range
Modem Adapter in order to connect to one half of the SRM Pair. The other half
of the SRM Pair is connected to a free serial port on your computer. The SRM
Pair is connected using a 2-twisted pair cable (Davis Product #7884) which is
not included. Using 22 AWG cable, you may run up to 4 miles of cable between
the SRM Pair. Using 18 AWG cable, you may run up to 8 miles between the
SRM Pair.
