Author Topic:   SIMRAD IS35 NMEA-2000 Color Display

SIMRAD has a recently announced NMEA-2000 color display, the model IS35. The display size is described as 3.5-inch and is an LED backlit LCD display. The IS-35 is a NMEA-2000 display device, and connects to a NMEA-2000 network using a single DeviceNET Micro connector, the now common NMEA network connector. It gets its power from the network, making installation very simple. The retail price is about $400.

The gauge face is almost square but the body of the device is round, and it mounts in a 3.3-inch-diameter hole (83-mm). (A 3.3-inch hole can usually be cut with a 3-5/16 hole saw.) Four self-taping screws, one at each corner, secure the gauge to an instrument panel and then are concealed by a snap-fit bezel The overall size of the gauge is about 4-inch-wide by 4-1/8-inch-high.

The gauge has four actual front panel pushbuttons. The function of the buttons remains constant in the user interface. They are labeled

--(left arrow)
--(right arrow)

The MENU and ENTER keys have dual functions, depending on how long the button is held depressed. The user interface is organized in hierarchical menus, submenus, and selection choices.

Data presentation is pre-organized into five fixed-data default pages, described as:






In addition, the user can edit and modify these pages to alter their appearance and the data they present.

FUEL MANAGEMENT is also provided in the IS35 gauge. Full-tank and partial-tank re-fills are provided, and two accumulators track fuel used. ALARMS are also monitored, logged, and can be reset via the IS35. There are many language options for the data presentation. The IS35 also has its own USB connector on the rear panel. A USB storage volume can be connected to the IS35 for the purpose of reading or storing files, and for accomplishing firmware updates.

NMEA suggests that NMEA-2000 devices come with a listing of the parameter group number (PGN) for the data they can send or receive. Usually Simrad supplies this information, but I could not find a listing for the IS35. I suspect that the IS35 can handle a wide range of NMEA-2000 data, given Simrad and parent NAVICO have a long history in and lots of experience with NMEA-2000.

It appears that a version of the SIMRAD IS35 color display is being sold under the Suzuki brand name as a new option for NMEA-2000 instrumentation with Suzuki outboard engines.

The operating guide for the SIMRAD IS35 display warns users about the fuel management function:

Vessel fuel remaining will only be shown when fuel flow data is available and a fuel storage device such as an EP-85R is on the network.

This suggests that if you have been using a Lowrance multi-function display and already have an EP-85R DATA STORAGE MODULE on the network, it may work with the IS35 display. I say "may work" because the EP-85R has quite a history of needing to have its firmware coordinated with the display device it is going to work with.
