I purchased this unit to interface with a Sterling ProCharge Ultra ST-PCU-1260, which is identical to a ProMariner ProNautic 1260P. I use this on a boat, and will periodically have to run the generator while I'm away from the dock to recharge the house batteries. I would have to keep peeking into the engine room in order to see the charger display to know whether or not I'd put a sufficient enough charge on them, or should keep running the generator longer. I mounted this remote display at the boat's breaker and electrical panel. Now, I just have to glance at it to know exactly what the charger is doing.The cable used appears to be a standard phone jack of some sort, and passes both power and the signal. I don't recall whether it was four or six pin, but it seemed to me that buying extra cord for a longer connection, or cutting this one and crimping on a new end with the proper tool, wouldn't be out of the question. I had more than enough to pass through the engine room to the panel, and just wrapped up the excess and zip-tied it to a convenient spot. I drilled a 1/2" hole in a blank area of my panel to pass the wire through, then used 3M double-sided tape (the thin, grey stuff) to hold it down. It did not come with mounting screws, but does have four holes should you want to drill some more. A rectangle could also be cut for flush mount, if desired. For flush mount, part of the bezel slips off so that you have a flange to overlap the hole.There are not a lot of instructions, and only few things to do. Really the only options I can find are to turn the back-light off, change the language, and change from either scrolling through all the display options or leave it on just one.I like that there is additional information available from the charger unit through this display. Various temperatures, such as batter, charger, and transformer, can all be seen. There is also an indicator showing time until full charge.I like the scrolling display, but I wish some screens could be turned off. For example, I don't need to see the service phone number and the charger part number that it's connected to more than once after startup. Primarily, I want to see the current and voltage the charger is outputting. Most likely I will not use the scrolling feature and just leave it on the charger output screen.When the AC power is removed from the charge, the remote display turns off as well.All-in-all, a nice little device to monitor at a glance what's happening down below. I'm pleased with the purchase.greatEasy to install, and worth the money,, having this at my helm is nice.works just as it says it will. I would have given 5 starts, except it is connected to the multi bank charger and this remote station will only display information for one bank.Works as advertised but could be better. Really needs a nmea 2000 interface. Would be nice if it was powered by the batteries so you could see battery voltage. Its only on when ac power is available.My charger is in a stern compartment on my sailboat and not easy to read. The remote installed below on my cabin control panel makes it easy to monitor my batteries. Just had to run what looks like a phone cable from the compartment to the control panelA very nice addition to a ProMariner charger installation. There are a number of pages of useful information provided in a small footpront. This is a mount, plug & play display that comes with plenty of cable. I mounted it approximately 8 feet from the charger and still had quite a bit of extra length to coil and secure (I did not measure it before installing so can’t give an accurate length.Install was easy however routing the wire was a pain in the neck. Recommended future upgrade would be offer a bluetooth or wifi option. Tell me what the charger is doing at the helm. No need to go down into the engine room to see what the charger is doing. I recommend this product for peace of mind.Received on time, looks professional and solid.Will be installing in two days and I will give my commentsMust need if you have pronautic charger
