Reya Vision 4 Battery Supervisor

Does anyone have any experience with the Reya Vision 4 Battery Supervisor? I recently came into a deal on one so I picked it up and now I'm to the installation phase and having difficulty deciphering the wiring diagram. There is little-to-no information in the literature to explain the connections for the alarm relay or CAN hook-ups. Below is the link to the manual. I'm having trouble understanding connections 1-3 and 7-10 (everything else is pretty self-explanatory). Any help at all would be much appreciated.

Do you have a CAN bus on your boat? I seriously doubt it... most sailboats don't use a CAN bus.

If you don't have a CAN bus on the boat, you won't be using Pins 7-10.

Pins 1-3 are used for an alarm relay. If you don't have one, you don't need to use those pins either.

thanks sailingdog--that's what I suspected but it's great to hear it from someone else!

Another question: For house batteries, I use 3 Rolls Series 4000 batteries with a combined capacity of 408AH. Two of these batteries are in parallel (Batt 1) and the third is solo (Batt 2). Both banks run to a battery switch which selects between Batt 1, 2 or BOTH. If I position the shunt for the battery monitor downstream of this switch, will switching between banks confuse the monitor? The manual says that when first hooked up, the batteries need to complete a discharge/charge cycle before correct readings are shown. Would this apply each time I isolated one of the batteries?
