Datasheet
Lightweight Command Unit
Description
ORTs and DORTs are controlled
using a frequency band specific
Lightweight Command Unit (LCU)
which consists of an over-the-side
dunking transducer connected either
to a splash-proof handheld terminal
or, via supplied software, to any PC.
The Type 7663 unit is a Medium
Frequency LCU for commanding
ORTs whilst the Type 7667 LCU is a
Low Frequency unit suitable for use
with DORTs
For security of operation, a special
coding system provides protection
against accidental release by noise
or acoustic transmissions from other
equipment. Each ORT or DORT has
its own unique ‘address’ enabling a
number of units to be deployed in the
same area without risk of
interference.
