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.

Good enough
Size: 15x6.8, Color: Black
As cheap as the day is long but functional. These are basically made out of highly compressed paper and finished to feel like wood. The first one I put up was good with a little tilt to the back which is fine. The second one has a more severe tilt and I had to bend the bracket down to decently level it out. They are sturdy enough to hold quite a bit of weight and look good for what they are. I'm not impressed but I'm also not disappointed, the price is a bit steep for what they are but they serve their purpose.

Great, but bring your own inserts.
Size: 24x7.9, Color: Black
These work great, easy to install. Happy with them. Only problem was the instructions say don’t use the include inserts on wallboard, which meant I had to go out and purchase my own. That’s OK, because I like to use inserts I trust.

Love the shelves, great quality and design. They are very sturdy and perfect for my need. I ordered wine glass holders from Amazon and attached them to the shelves. Impressed and amazed at the look.

Great shelves
Size: 16.5 Inch, Color: Rustic Brown
I loved these for my room, they were easy to install and super versatile, I love how easy it was to assemble them and how functional they became once I was done setting them up. They fit perfectly next to each other and I love how my room looks nice since I don't like relying on bookshelves or anything of that category and rather have wall shelves. They are really stable and I love how they look, they are also really easy to clean since I spilled some baby powder from my last waxing session and they clean up pretty well. Overall, just know that these shelves are super stable, durable and versatile, I love how many things can fit on it if you know how to organize or don't have much stuff to put on them; it's all up to you and what you need them for, so I recommend them 10/10!
