RS-232 to E-TEC EMM Cable
Posted: Thu Apr 20, 2017 10:22 am
RS-232 to legacy E-TEC EMM diagnostic port cables are available from me for delivery to postal addresses in the USA via U.S. PRIORITY MAIL. You must have a postal address that can accept a small box. Priority Mail provides two-day delivery from Michigan to most of the USA. Payment is via PayPal; you must be able to send US funds via PayPal. The cables are priced at [$44] and this includes the cost of shipping. Please contact me via email if you would like to order a cable.

Connecting to the RS-232 serial data diagnostic port of the Evinrude legacy E-TEC outboard engine and its engine management module (EMM) requires an unusual cable. About eight years ago (2009) I wrote an article disclosing all the details of the cable and how to assemble one. The linked article explains in detail how to fabricate this special cable.
Many boaters were not equipped to fabricate these cables themselves, and I received a number of inquiries asking if I had cables to sell. From time to time I have made batches of these cables and offered them for sale. I recently made a new batch of the cables and have them available for sale.
The cables I make are assembled in Michigan by me using high quality new components.
The wire is BELDEN 8451, an 22-AWG shielded pair communication cable, and is [9]-feet long. Technical data about the cable is available from the manufacturer.
The engine connector is made by Amphenol and is similar to the European Deutsch connector. I use the more expensive machined solder cup pins in preference to crimp pins.
The common DB-9F connector is made by Amphenol and is also a solder cup connector.
The DB9 backshells are plastic and assemble with nuts and bolts rather than snapping together.
The wire-to-pin connections are hand soldered, by me. I have extensive experience in soldering electrical and electronic components--five decades. Each connection is inspected visually with magnification and tested electrically for continuity and shorts. The entire cable assembly is tested at 230,000-bps in a serial data communication circuit.
These cable assemblies can be disassembled in the field if repair becomes necessary. Since there are no crimped contacts, all connections can be repaired and reused by soldering. The backshell of the DB9 can be easily removed if the cable needs to be threaded through a rigging grommet on the engine.
These cables are just cables. They do not provide a USB-to-serial adaptor that may be necessary for use with newer computers that lack actual physical serial ports.
