materials that can withstand harsh environments. However, con-
tinual exposure to UV light, or periodic submersion should be
avoided to extend the life of the components.
Communication between the base and remote modules are rated
for distances as great as 1/2 mile (800 meters), line of sight.
However, obstructions such as buildings and industrial
equipment between the modules may reduce the effective dis-
tance.
Typically, the modules are suspended inside a manhole. Sus-
pending the module near the opening will protect it from the ele-
ments, minimize the chance of submersion, and allow it to be
easily retrieved without entering the manhole. In most instances,
this location near the opening will allow for successful wireless
communication.
Typical communication distances possible using internal
antennas are:
• Line-of-s ight: 1/2 mile (0.8 km)
• Inside closed manh ole: 100 feet (30m)

Connecting the Modules To connect the 2100 Parameter and Battery modules, refer to the
following instructions and Figure 3-2.
1. On the top of the Battery Module, remove the cap and stow
it on the holder. This exposes the communication connector
on the Battery Module.
