NMEA 2000 Engine Monitoring Unit - Analog to NMEA2000 Engine Gateway

Share engine information on the NMEA 2000 bus.

The Actisense EMU-1 is a specialized analogue to NMEA 2000 Gateway which converts data from analogue engine gauges/senders into NMEA 2000 data. The EMU-1 enables the sharing of engine data throughout the NMEA 2000 bus. It digitizes analogue engine sensors, enabling NMEA 2000 display devices to monitor the connected engine(s) on a vessel.

The EMU-1 can monitor vital engine parameters such as temperature, pressure RPM and fluid levels from up to two engines.

The EMU-1 has a PC-based configuration tool that allows the settings inside the EMU-1 to be changed to best suit the engine it is working with, making it a flexible solution for many engine makes and models.

An Actisense PC to NMEA 2000 Gateway (NGX-1/NGT-1) is required to configure the EMU-1.

The NGX-1 or NGT-1 must be used to update the firmware, connect the Toolkit and display data on a PC for diagnostic and information purposes, using NMEA Reader. Please visit the NGX-1 page and/or NGT-1 page for product details.

So so...
Size: Medium, Unit Count: 2
They do what they advertised. You can NOT walk in them you will stretch them and pop a hole in them. You cannot sleep in them unless your going to wear larger cotton socks with them to keep them in place. They are easy to wash and dry which is nice. I will need to buy another pair. Great if your gonna watch a movie or binge TV in.

Great for dry feet or to help lock in moisturizer or medication
Size: Medium, Unit Count: 2, Size: Medium, Unit Count: 2
They’re stretchy and don’t feel goopy, I use them daily and they’re working great they keep my feet nice and hydrated and soft. I’ve been using them along with lotion to help hydrate my skin so they aren’t rough during the winter. They are comfy and if you must get up they’re grippy and don’t slip or slide they stay put. They’re super easy to put on and take off.

Do not buy this
Size: Medium, Unit Count: 2
This is not a good product ! Whenever I put products on my feet and put them on the socks they were on for about 2 to 3 minutes I had to keep adjusting them on my feet then they started ripping
