Connecting E-TEC Engine to SIMRAD NSE-8

Connecting an Evinrude E-TEC engine to a SIMRAD NSE-8 multi-function display may require use of an adaptor cable. The SIMRAD devices support NMEA-2000 networking, so they can read data from an Evinrude E-TEC engine, but SIMRAD appears to be using slightly different connectors and wiring accessories than the standard NMEA-2000 DeviceNET Micro C connectors.
A Lowrance document explains about using NAVICO multi-function displays with E-TEC engines, and is available for download from Lowrance.
The Lowrance-branded or Evinrude-branded Evinrude Engine Adaptor Cable is designed to connect to a network that uses the standard NMEA-2000 DeviceNET Micro connectors, compatible with LowranceNET RED connectors (which are actually now black). The concern with the NSE is the arrangement of the NMEA-2000 connector on the device. On the NSE the network and the connector may be called a SimNET network and connector.
I don't have any first-hand experience installing an NSE multi-function device, so I don't know exactly what the connector arrangement will be. Searching on-line I found the installation manual for the SIMRAD NSE-8 which has a great deal of detail about the network wiring. There are essentially two possibilities for the NMEA-2000 connector on the NSE. It can be:
--the standard DeviceNET Micro connector, or
If the connector is the standard DeviceNET Micro connector, it will be completely compatible with the LowranceNET RED connectors. If it is something else, you have to decide what network backbone wiring to use.
From looking are the SIMRAD literature, it appears to me--but this needs to be verified--that the SIMRAD SimNET connectors are not compatible with the standard NMEA-2000 connectors. I draw this inference from the literature on page 78 of the installation manual. There is a listing of accessory cables there. The listing includes adaptor cables for each situation, that is, for connecting a Lowrance-type device to a SIMRAD backbone, or for connecting a SIMRAD device to a Lowrance-type backbone. If the two backbones used compatible connectors it would seem like an adaptor would not be necessary. That said, however, one ought to look at the actual connector on an NSE-8 to see what is there.
Depending on the particular equipment used on a boat, it may be more convenient to construct the network backbone with the more standard DeviceNET Micro C connectors, also known as LowranceNET RED connectors, and use an adaptor cable to create a drop cable to connect the SIMRAD NSE to the backbone. On the other hand, in some instances, perhaps the boat will have a majority of SIMRAD devices on the network, and in that case it may be advantageous to make the network backbone wiring conform to the SIMRAD style of connector, and use a specialized adaptor to connect Lowrance-style devices, for example, to connect the E-TEC engine adaptor cable. This will depend on the the particular installation and what electronic gear is contemplated.

The most easily obtained E-TEC engine NMEA-2000 cable is designed to connect to DeviceNET Micro C connectors or LowranceNET-RED connectors. See
If you want to use this cable with a SimNET backbone, you probably will need to obtain the adaptor from SIMRAD so you can connect this engine cable to the SimNET backbone:
24006199--SimNet to Micro-C (female) cable that connects a NMEA2000
If you use a standard DeviceNET Micro-C network backbone, to connect the NSE-8 to the backbone you will probably need to obtain an adaptor from SIMRAD:
24005729--SimNet to Micro–C (male) cable that connects a SimNet product to
Again, which path to go depends on how much SIMRAD equipment you expect to have on the boat.

Instructions on how to set-up the NSE-8 with a NMEA-2000 engine like an E-TEC are a bit sparse. In the Installation Manual on page 52 under the general topic of COMMISSIONING THE SYSTEM there is a brief explanation of how to use the menus to reach the NMEA-2000 source selection for engine. However, it is likely the NSE will automatically recognize the E-TEC, and a manual setting may not be necessary.
The installation instructions can be downloaded from SIMRAD's website.

From further reading, it appears that on the SIMRAD NSS models the NMEA-2000 connector has been changed to be a standard DeviceNET Micro C connector. This means that a SIMRAD NSS device should be able to connect to a NMEA-2000 network backbone that is wired with the standard DeviceNET Micro C or LowranceNET RED connectors without any adaptors. A standard drop cable should be compatible with the NSS device's connector.
