The DMC 3000 is provided with extension capability at the bottom of
the case.
For this purpose, a 26-pin connector allows connection for the
following:
Bidirectional serial communication
Report alarm signal
Detection module (Neutron, Hp(0.07), etc.)
External power (*)
Before connecting any external add-on module, it is necessary to
equip your DMC 3000 with a connecting board, reference 153 458
on top of the 26-pin connector.
(*) Before connecting an external power source to your DMC 3000, make
sure that the AAA battery is removed.
The applied voltage should not exceed 1.6 V, typically remain at 1.5V and should not be lower than 1.3 V.
The typical consumptions are given on the below table:

Note :
Due to current being present on the pins when the DMC 3000 is energized, take care when attaching new modules
or adapter board not to short any of the pins.
The add-on module must be attached or removed only when the DMC 3000 is in PAUSE.
