Description

Noland Md33 Engine MonitorNoland MD33 Engine Vessel Monitor Model: MD33 The MD33 is a data monitor system specifically designed for dual engine vessels. It converts rpm, analog gauge, and alarm status(on off) sensors into NMEA 2000 messages for display by MFD's(multi function displays). It also accepts NMEA 0183 navigation data which it sends, along with engine data, to a PC for display and logging by our C Port2 software. The MD33 is compatible with most marine engine sensors

Noland MD33 Engine/Vessel Monitor

Model: MD33

The MD33 is a data monitor system specifically designed for dual engine vessels. It converts rpm, analog gauge, and alarm/status(on/off) sensors into NMEA 2000 messages for display by MFD's(multi-function displays). It also accepts NMEA 0183 navigation data which it sends, along with engine data, to a PC for display and logging by our C-Port2 software. The MD33 is compatible with most marine engine sensors whether or not gauges are present. Setup and calibration is done via a PC-USB interface and supplied software. All analog engine and alarm connections are made to a terminal strip on the rear of the unit, while rpm and NMEA 0183 connections are made to the front terminal strip. A standard micro-C connector is provided for NMEA 2000 hookup. All data interfaces, USB, CAN, and Engine, are galvanically isolated from each other.

RPM is sensed directly from Alternator output, sending units, or ignition pulses. The user must set the number of pulses-per-revolution (ppr) for each engine. Analog (gauge) inputs can be taken from existing gauges or resistive senders which can be powered by the MD33. Analog inputs A1-A4 sense 0-20V while A5 can sense inputs up to 40V for direct sensing of Battery Voltage. Alarm/status inputs sense the presence or absence of voltage from switches, relays, or senders. Setup and calibration software is included.

Comfortable and light!
Color: Brown, Size: Large
Wanted something that was going to be lightweight but had those longer sleeves because I do still get a tad chilly even on the warmer days. This is perfect, the fabric is lightweight and breathable, the loose cut around the waist adds to the top's "breathability," but it still keeps you cozy and warm on those chilly mornings! The brown is a lovely warm-coffee tone and it hasn't faded a bit in the wash. Very nice shirt to add to your collection!

looks nice, well made and styish.
This was a gift for a friend. It is well made, has a good modern style to it, comfortable to wear, she is taller, and it fits her well. Its a bit warm, so a fall kind of clothing option.
