2.2 Installing transducers
Transducer types
ST70+ can operate with:
•
Conventional transducers (separate Speed, Depth and Wind).
• Smart transducers (combined Depth/Speed/Temperature (DST) and combined
Depth/Temperature (DT) transducers).
The main difference in installation requirements for these two groups is that each
conventional transducer connects to a dedicated pod which then connects to
SeaTalk
ng
via a fitted SeaTalk
ng
spur cable, whereas each smart transducer connects
directly to the SeaTalk
ng
backbone via a fitted SeaTalk
ng
spur cable.
Fitting
Fit each transducer in accordance with the accompanying instructions.
Connecting
Conventional transducers
CAUTION: Do not use the wrong pod
Using the wrong type of pod could cause damage to your equipment. Before
connecting, always ensure that the pod you intend to use is compatible with
the transducer type.
Conventional transducers and associated pods are available for wind, depth and
speed. Each transducer connects via a dedicated pod to SeaTalk
ng
.
Connect each conventional transducer as follows:
1. Ensure the pod you intend using is compatible with the transducer, i.e. speed pod
for a speed transducer, depth pod for a depth transducer or wind pod for a wind
transducer.
