8-PIN TRANSDUCER ADAPTER BOX

INSTALLATION INSTRUCTIONS

Important Safety Information

WARNING

See the Important Safety and Product Information guide in the device product box for product warnings and

other important information.

CAUTION

To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,

cutting, or sanding.

NOTICE

When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.

This transducer adapter box is not intended for use with a Garmin

differential 8-pin transducer. Do not cut a

Garmin differential 8-pin transducer cable. Connect it directly to the 8-pin port on the sonar module.

This adapter box connects a non-differential transducer, such as a Garmin or Airmar

™

6-pin transducer, to a

Garmin 8-pin sonar module. To adapt a non-differential transducer for use with a Garmin differential sonar

module, you must cut the connector from your existing non-differential transducer and connect the wires to the

wire block inside this 8-pin adapter box by following these instructions.

Mounting the Transducer Adapter Box

Tools Needed

• Drill and 3.2mm (

in.) drill bit

• #2 Phillips screwdriver

• 3mm flat screwdriver

• Cable ties (optional)

• Wire cutter

• Wire stripper

• 21mm (

in.) wrench

• 15mm (or adjustable) wrench (optional)

Mounting Location Considerations

When selecting a mounting location, observe these considerations.

• The adapter cable from the device should reach the transducer connector on the sonar module easily when

the device is mounted. The adapter cable length is 60 cm (24 in.).

• You must not submerge the device in water.

• You must mount the device at least 15.25cm (6in.) from a source of electrical interference, such as a motor.

• When a mounting surface is unsuitable for screws, you must secure the device to a structure using cable ties

(not included).

This document provides installation instructions for the Garmin 8-Pin Transducer Adapter Box, designed to connect non-differential 6-pin transducers (such as Garmin or Airmar models) to Garmin 8-pin sonar modules. It is crucial to note that this adapter box is not intended for use with Garmin differential 8-pin transducers, and users should not cut a Garmin differential 8-pin transducer cable; instead, it should be connected directly to the 8-pin port on the sonar module.

Function Description:

The primary function of the 8-Pin Transducer Adapter Box is to enable compatibility between older or non-differential 6-pin transducers and newer Garmin sonar modules that utilize an 8-pin differential input. This is achieved by providing a wire block within the adapter box where the wires from a cut 6-pin transducer cable can be connected according to specific functions (Depth +, Depth -, Shield, Ground, Temp +, XID, Speed power, Speed data). This allows the non-differential transducer's signals to be properly routed and interpreted by the differential sonar module. The adapter box essentially acts as a bridge, converting the wiring scheme to match the requirements of the 8-pin sonar module.

Important Technical Specifications:

Dimensions (W x H x L): 59.1 x 48.97 x 104 mm (2.3 x 1.9 x 4.1 in.)
Cable length (adapter cable from device to sonar module): 61 cm (24 in.)
Water rating: IEC 60529 IPX7. This rating indicates that the device can withstand incidental exposure to water of up to 1 meter for up to 30 minutes. For more information, users are directed to www.garmin.com/waterrating.
Compatibility: Designed for non-differential Garmin or Airmar 6-pin transducers. Not compatible with Garmin differential 8-pin transducers.
Wire Block Connections:
- 1: Depth + (Transducer depth positive)
- 2: Depth - (Transducer depth negative)
- 3: Shield (Transducer cable shield)
- 4: Ground (Sonar system common ground)
- 5: Temp + (Water temperature positive) - Requires a jumper between connectors 4 and 5 if the transducer lacks temperature capability.
- 6: XID (Airmar Transducer Identification)
- 7: Speed power (Speed wheel sensor power positive)
- 8: Speed data (Speed wheel sensor data positive)

Usage Features:

Adaptability: Allows users to continue using their existing non-differential 6-pin transducers with newer Garmin 8-pin sonar modules, potentially saving the cost of purchasing a new transducer.
Sensor Integration: Supports optional connection of separate temperature sensors and water speed wheel sensors through dedicated nuts on the housing, expanding the data input capabilities for transducers that may not have these integrated.
Clear Wiring Guidance: Provides detailed wire function descriptions and wire color tables for various Garmin and Airmar 6-pin 50/200 kHz dual-frequency and high-power dual-frequency transducers, simplifying the wiring process.
Chartplotter Configuration: Reminds users to set the transducer type on their chartplotter to "Dual Freq (200/50 kHz)" for optimal performance with 50/200 kHz dual-frequency transducers.

Maintenance Features:

Secure Mounting: The adapter box is designed for secure surface mounting using screws, with instructions for drilling pilot holes and tightening for a firm attachment.
Cable Management: Includes a nut on the housing to secure the transducer cable entry, ensuring a tight seal and strain relief. Cable ties are suggested as an optional method for securing the device if the mounting surface is unsuitable for screws.
Environmental Protection: The IPX7 water rating ensures the internal components are protected from water ingress during normal marine use, enhancing durability.
Installation Safety: Emphasizes safety precautions, including wearing safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding. It also warns users to check the opposite side of the surface before drilling or cutting to avoid damaging the vessel.
Electrical Interference Consideration: Recommends mounting the device at least 15.25 cm (6 in.) from sources of electrical interference, such as a motor, to ensure optimal signal integrity.
Wire Preparation: Suggests tinning stripped wires before connection to the wire block, which can improve electrical contact and prevent fraying.
