B17 D Through Hull Retractable Transducer · M78717
iTC-5 · Direct
Analogue transducer terminals
No additional adapter is required for this connection.
Functions: Depth
This match applies to the analogue version of the exact code. iTC-5 is installed on the SeaTalk NG backbone.
Calibration requires a compatible display. i40/i50/i60 cannot calibrate transducers through iTC-5.
Avoid operating another sonar at the same frequency as the instrument depth transducer simultaneously.

i70s · Through a module
SeaTalk NG backbone
Shared SeaTalk NG network with separate branches. A powered and terminated backbone is required; this list is not a wiring sequence.
Additionally required:1 × E70010 — iTC-5 Instrument Transducer Converter
Included with E70327:1 × A06038 — Spur Cable 400mm
Functions: Depth
A powered, correctly terminated SeaTalk NG backbone is required. iTC-5 connects to the backbone; it is not a direct transducer-to-i70s cable.
Calibration is performed from i70s. Backbone components depend on the existing network.
