DIGITALLY ENCODED SECURITY
SYSTEM 6
GENERAL
The Digitally Encoded Security System (DESS)
features an anti-start protection against unautho-
rized use of the watercraft.
The following components are specially designed
for this system : Multi-Purpose Electronic Module
(MPEM), safety lanyard cap and safety lanyard
switch.
The safety lanyard cap has a magnet and a ROM
chip. The chip has a unique digital code.
The DESS circuitry in the watercraft MPEM is ac-
tivated at the factory. Therefore, a safety lanyard
must be programmed to start the engine.
NOTE : Actually, it is the memory of the
MPEM which is programmed to recognize
the digital code of the safety lanyard cap. This is
achieved with the MPEM programmer (P / N 295
000 127). Refer to its guide to program a safety
lanyard.
The system is quite flexible. Up to eight safety
lanyards may be programmed in the memory of
the watercraft MPEM. They can also be erased.
NOTE : If desired, a safety lanyard can be
used on any watercraft equipped with the
DESS.
The memory of the MPEM is permanent. If the
battery is disconnected, no information is lost.
The memory of the MPEM has also two self-diag-
nostic modes.
When ordering a new MPEM from the regular
parts channel, the DESS circuitry will not be acti-
vated. If desired, it can be activated with the
MPEM programmer.
NOTE : If the DESS circuitry of the water-
craft MPEM is not activated, engine can be
started with any safety lanyard. Once the DESS
circuitry is activated, it is not possible to deacti-
vate it. A safety lanyard must be programmed to
start the engine.
