The cylindrical canister houses all electronics, and usually the
batteries, and is designed for suspension within a manhole or
other wet environment.
Note
The current canister controller has four connector ports. Earlier
models included a fifth Auxiliary port for the connection of an
external modem.
A fifth port is sometimes still added to current models as a spe-
cial power switch controlled by a sampler enable signal input.
