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.

i should have waited for there to be reviews posted
Format: Kindle
I'm being more generous than I should because this is a debut novel i downloaded this book because i like why choose and band romances i figured that it wouldn't take too long to get back to where the prologue was because the prologue seemed to be less than a day before they met the FMC and the MMCs don't meet til 60 % of the way in which for a Romance novel kinda hard for the relationship to develop or for there to be plot beyond them just meeting in a way where the FMC really lacks agency a lot of early plot and character things are forgotten about after they met it's almost as if the last third of the book was written first and then they went back to write backstory separately but forgot there needs to be a plot i get wanting to have background on the characters, but there has to be a way to do it without constant time jumps and no plot progression. Tessa's story jumps around a week lead up so much also the band aspect is very much an afterthought in the novel Spoilers-- one of the MMCs is openly pan and one of them has been dealing with a bi awakening but being somewhat defensive about it and once Tessa arrives that gets forgotten about til the epilogue and even then doesn't actually confront his sexuality the wrap up of the church hiding her name is tied up with a quick sentence, but no real consequences for anyone i honestly thought she forgot about family pack IRS deal until the final chapter and that gets resolved in an unsatisfying way the pack is upset that Tessa gets viewed as an object and tricked into the contract but has no interest in making the company's wrongdoings public or trying to prevent this from happening to other omegas tessa goes over a lot of struggles of homelessness but she only thinks about food waste once after joining the pack -- you'd think she'd use her newfound wealth and power to help other homeless individuals, especially youths and omegas. even a little side note to say that a portion of tour proceeds or her family fortune would go towards public food pantries and shelters would've done something to connect her beginning character to the end character

BORING and too long
Format: Kindle
I could not believe how wordy and boring this book was. No spice at all. Slow burn is really a NO burn. Almost DNF and now I’m sorry I stuck with it. 500 pages could ave been 150 and it would have been more than enough. I highly doubt not recommend this work of yuck.

Still 4 stars
Format: Kindle
A little to much before and to much dive into the days, months before, but I still kept reading. Maybe because of that you could read about them all. I just couldn't put this book in my to read another day list. I just wanted to know what happens to them.

Promising but not without issues
Format: Kindle
First off, the FMC and the pack don't meet until about 60% of the way through. That's just way too late honestly. I can appreciate the backstory of the band and the FMC, but I skimmed at times wondering when they'd meet. I did like the writing and premise but I thought the execution needed a lot of work. The characters were pretty well developed, but they didn't spend that much time on the page together, so I thought that led to the story suffering. I will give her another shot, as I think the writing has promise... It just didn't come all together in a way that I could wholeheartedly recommend.
