PRO NMEA 0183 Buffer - 2 OPTO Inputs, 12 ISO-Drive Outputs, Serial Port, Ethernet Port, Pluggable Screw Terminal

Two OPTO-isolated inputs and twelve ISO-Drive™ isolated outputs. Offering device protection and excellent flexibility, all in one product - the Actisense® PRO-BUF-2, the intelligent, type-approved PRO range buffer.

The PRO-BUF-2 is rugged, with a stainless steel housing, and provides isolation on all inputs and outputs. With two NMEA 0183 inputs, twelve NMEA 0183 outputs, a bi-directional serial port, and an Ethernet port, the PRO-BUF-2 is a perfect solution for larger leisure vessels, commercial shipping, and is a great addition for systems that require type-approved devices.

The PRO-BUF-2 is designed to suit the majority of NMEA 0183 systems and is ready to go ‘out of the box’ by simply hard-wiring the two-mode inputs as required.

The Intelligent NMEA 0183 Buffer's manually configurable basic modes of operation include variations of buffer modes, intelligent auto-switch, and combine modes.

For all other configurations, leaving the mode inputs floating selects the ‘User Configuration Mode’. The web-based configuration tool allows full customisation of the PRO-BUF-2, and is compatible across all popular Operating Systems. Using the web-based configuration tool allows for fine-tuning of the data available on each output.

To make installation quick and simple, the PRO-BUF-2 features 2-part pluggable connectors that allow the use of screw terminals*, and a professional DIN Rail mounting system (DIN Rail not included). The device can also be mounted directly to the bulkhead.

Helpful LEDs indicate power, data in, data out, and the alarm status to aid diagnostics.

Data statistics and load indication via the web tool provide a real-time view of data.

The Best Interactive Dog Toy My Dogs Won’t Put Down!
Color: Blue
I have a Labrador and a Jack Russell and I bought this Qraxond interactive ball mainly for my Lab’s strong hunting instinct but I was absolutely blown away by how both dogs went crazy for it. This toy isn’t just fun it’s a total game changer for keeping pups entertained stimulated and out of trouble when I’m busy. The ball arrived nicely packaged with clear easy to follow instructions. It comes with a USB C charging cable for the internal motor no wall adapter included but any standard USB plug works perfectly. The bright blue color is such a smart choice it stands out everywhere so I never lose it in the yard carpet or under furniture. Operation is incredibly simple. The inner vibration module is held securely in the ball with heavy duty velcro. Inside a rubber core vibrates and makes the whole ball move and bounce unpredictably. There’s a protective plastic flap covering the charging port just press the button once for low mode again for high active mode and a third time to power off. Super intuitive for anyone to use. The build quality is solid. While it’s not designed for aggressive chewers and the seller clearly states that which I really appreciate it holds up amazingly well for normal play. My dogs love shaking it tossing it and playing tug of war with me and each other and the toy hasn’t shown any signs of weakening. The reinforced fabric loops are stitched tightly and make it easy for dogs to grab shake and carry even my Lab has a blast tugging on it and the vibration keeps him distracted from pulling too hard. The motion activated vibration works incredibly well. It’s highly sensitive so it activates as soon as your dog paws nudges or moves it then shuts off automatically when play stops to save battery. Both speed modes are a hit the low setting is gentle but engaging and the high setting gets them zooming around. The random movement triggers their natural prey drive so they can play independently for 10 to 20 minutes straight something my people focused standard poodle rarely does without human interaction. It’s fantastic mental stimulation that tires them out without me having to throw a ball a hundred times. It’s truly versatile for all dog sizes and breeds you can’t get more different than a Labrador and a Jack Russell yet both adore it. I ended up buying a second one just to stop them from fighting over it! The soft padded outer cover is gentle on teeth and gums and since the instructions note to remove the inner core before cleaning the cover is clearly machine washable making cleanup a breeze. Battery life is impressive it lasts through multiple play sessions before needing a charge and USB C charging is as convenient as charging a phone. At under $25 this toy offers incredible value way better than similar products I’ve tried that cost twice as much. If you’re tired of boring toys that get ignored or need a way to keep your dog busy and mentally stimulated while you work or relax this Qraxond interactive ball is a must have. It’s durable fun easy to use and loved by every dog I’ve seen play with it. Highly highly recommend one of the best pet purchases I’ve ever made!

My dogs love this ball
Color: Blue
This interactive dog ball has been a huge hit with my doodles — Simba, Roxy, and Ozzy! The second I turn it on, they go crazy chasing it around the house. It keeps them entertained, active, and mentally stimulated, especially on rainy days when they can’t burn energy outside. I love that it moves on its own and keeps them engaged without getting bored after 5 minutes like most toys. It’s durable enough for energetic dogs and rechargeable, which is a huge plus. Definitely worth it if you have playful pups that need extra stimulation and exercise!

The dog likes it, til her short attention span kicks in
Color: Green
This is an interesting toy. Our little doodle really likes it when it starts up. She does lose interest after about 30 seconds. I think it's the pauses in-between the 10 second Normal or Crazy Bouncing Mode. When she does play with it she is intense about it. The loopy handles are very handy. The company stands behind the product. I would buy it again.

A favorite toy in our house!
Color: Blue
This is the best interactive ball ever! It combines two of my pups' favorite toys...a soccer ball and weighted moveable ball. Perfect independent toy! We've had it for a few weeks and I've only had to charge it once. Amazing battery life.

Not great for smaller dogs
Color: Blue
Wasn't great for small dogs but well made and probably great for larger dogs.
