Humminbird 9 M SIDB Y 9-Pin Side Imaging Dual Beam Splitter Cable

9 M SIDB Y - 9-Pin Side Imaging Dual Beam Splitter Cable

The Humminbird 9 M SIDB Y Splitter Cable (Part Number 720101-1) connects a Side Imaging (SI) transducer and a Dual Beam 2D sonar transducer to a single control head simultaneously. It removes the need for a manual hardware switch by splitting the individual pin wiring internally.

Key Specifications:

• Cable Length: 30 inches.
• Connector Type: 9-pin.
• Frequencies Supported: 455 kHz, 800 kHz, MEGA Side Imaging, and MEGA Imaging+.
• Core Function & Layout
• The cable separates internal wiring to route specific data from two distinct hull positions back to the single display head:
• Side Imaging Side (SI): Directs Side Imaging, Down Imaging, and water temperature data from a high-mounted transducer (such as on a jack plate).
• Dual Beam Side (DB / 2D): Routes standard 2D sonar data from a low-mounted or shoot-through-hull transducer.
• Performance Benefit: Allows accurate bottom tracking and depth readings at high speeds while safeguarding the expensive Side Imaging transducer from floating debris.

Compatibility:

• Supported Systems: Humminbird HELIX 5, 7, 8, 9, 10, 12, and 15 series.
• Legacy Systems: Legacy 300, 500, 700, 800, 900, and 1100 series units.
• Incompatible Systems: Does not support APEX, SOLIX, or ONIX units (which require 14-pin configurations like the 14 M ID SIDB Y).
