J1939 Engine Diagnostic Capture

J1939 Engine Gateway

The J1939 Engine Diagnostic Capture service from Yacht Devices Australia is designed to allow customers to “Try before you buy”.

Why do I need this:

  • To confirm engine compatibility prior to purchase
  • To confirm what data is coming from the engine and therefore able to be visualised on the chartplotter.
  • To assist us with programming the gateway/s correctly the first time without the need for reprogramming after installation.

In most cases we can confirm compatibility of an engine prior to purchase when provided with engine serial numbers and models as well as photos of the gauges.

We cannot always advise exactly what data will be available from the engine onto the chart plotter. This service allows us to capture the data from the engine and confirm what will be available prior to purchase.

By capturing a log of the available data from an engine we can ensure the programming of the gateways is correct prior to shipping to avoid unnecessary reprogramming after installation.

By purchasing the J1939 Engine Diagnostic Capture service we will send you an engine gateway with microSD card inserted and programming setup to capture a log from your engine while running for a few minutes. If you have twin engines, you can run the diagnostic on either one or both engines. Based on what engine/s you have, we may also send a suitable adaptor cable with the gateway to allow easy connection to your engines’ diagnostic port. Once the capture has been completed, you send back the kit to us and we will then review the capture and advise on the data available and any other information that is relevant.

If you decide to purchase after a successful data capture, we will discount your order by $75

Ready to “try before you buy”?

First thing to do is email us at info@yachtdevices.com.au with your engine serial number, model number and any photos you have of the controls/gauges. Please also advise what connection type you require for the NMEA2000 network, either SeatalkNG (Blue and white connectors) or DeviceNet (Standard black connectors).

We will then confirm that your engines should be compatible and will ask you to purchase this service using the above “Add to cart”. Once purchased, advise us your best shipping address and we will get the kit in the mail to you including all instructions needed to connect and capture the data. A return address will also be included. It is the buyer’s responsibility to pay for return postage, including tracking.

Connection to the engine

For boats with Volvo Penta engines, you simply plug the device into a free socket on the NMEA 2000 network backbone and connect to a Multilink hub or, using the built-in Y-connector connect it in series with any of the EVC tachometers.

For other engines (please see section IV of manual for details) an adaptor cable is required.

Available adaptors:

  • EVC/Vodia 8-pin adaptor cable
  • EVC-A multisensor adaptor cable
  • EVC-A MC 12-pin C5:ENGINE cable
  • EVC-A EC 12-pin X5:MULTILINK cable
  • EFI 10-pin adaptor cable
  • Caterpillar Display 12-pin cable
  • Caterpillar Round 9-pin adaptor (C7, C9, C12, C18, C32)
  • Cummins Round 9-pin adaptor (QSL9, QSM11, QSX15, QSK 19/45/60)
