System and transducer connections 19
The numbers within the drawing refer to the detailed illustrations within this chapter.
Note: Only one temperature wire should be connected. (To
either the speed/temperature or non-diplexed transducer
input as appropriate.)
Non-Diplexed transducer cables
Non-Diplexed transducer cables contain wires bundled as
detailed and should be connected within the sounder module as
shown in the following diagram:
:
The overall screen must be connected to the unit earth bolt
using the ground spur cable supplied - refer to “Ground
connection” on page 22.
2.4 Custom transducer configurations
If the cable connections for the transducer you are using with
your DSM400 do not include an ‘Orange ID’ wire, you will need
to configure the sounder unit manually to match the power and
frequency of the transducer. To do this, use one of the four
override rotary switches located on the left of the sounder unit
printed circuit board (PCB).
