PLASHPROOF
TPU
or
use in open boat operations where exposure to rain and spray is likely,
a lightweight, rugged, splashproof configuration of the Transceiver and
Processor Unit (TPU) is available. The Splashproof TPU is similar to the
rack mount configuration but is housed in a watertight, corrosion proof, high
impact resistant Pelican Protector Case. Like the rack mount version, this TPU
connects to the towfish and to the Ethernet port of an optional or user supplied
ruggedized laptop computer running SonarPro.

General Description
The Splashproof TPU is shown
in Figure 6-1. It provides the
same functions and most of the
same external connections as
the rack mount TPU. All of the
connectors, indicators and
switches are splashproof and
are located on a connector
panel on the side of the case. In
addition, two view ports on the
connector panel allow viewing
of additional indicators inside
the TPU.
The Splashproof TPU is
powered from 115 or
230 VAC, internally switch
selectable, or from 12 VDC. A
switch on the connector panel
allows selection of the AC or
DC power source.
CAUTION
Do not submerge the Splashproof TPU in water as it is not
designed for continuous immersion. (See CHAPTER 2: “Specifications.”)
