Installing Locking Rings on the Cables
Before you install locking rings on the cables, you must route
the cables.

are packaged separately from the cables. Each locking ring is
packaged in a small bag with a number on the label for easy
identification.

Separate the two halves of the locking ring
2
Align the two halves
snap them together.
3 Insert the o-ring into the end of the connector.
Transducer Wiring Diagrams
Connecting the high-frequency wires to the low-frequency
terminal block, or the low-frequency wires to the high-frequency
terminal block, damages the device and the transducer.
You can use these diagrams to identify the connection points for
your transducer wires on the GSD 26 terminal block. Locate
your CHIRP/spread spectrum transducer model in the wiring

The outer shield wire must connect to one of the two screw
posts below the terminal block using the included ring crimp
terminal. When connecting two single-element transducers, you

wiring bundles. To identify the wiring groups in the bundles more
easily, you can remove up to an inch of the cable housing.
