    Hello All:
    I have a 4 port Smartcraft junction box (shown below) at the helm going to my present guages. I want to install the Vesselview Mobile device and do not have any ports available on the 4 port unit. Can I just purchase a Smartcraft 6 port junction box and swap it out, or is there a specific model or series number of 6 port that I need?

    You should be able to swap it out if memory serves. You might need a cap for the open port, but shouldn't require a terminator (resistor)

    I have been thinking about getting the vessel view mobile, which needs an open smartcraft port. Is that what you are doing, or are you just adding more smartcraft gauges?

    Hi Todd.
    Yes I want to try the Vesselview Mobile as well but have no available ports left. After talking to Mercury via email, they say swapping out a 6 port junction box is the simplest way to go.

    Perfect, probably my situation as well, but haven’t been to the boat to check it out. Part #878492T16? I thought they required a terminator, but it might just be a dust cap for the open ports. I am also considering the more expensive smartcraft to NMEA, and pair that with iKommunicate + wireless router, and you can get all your instruments on a configurable 20$ app, but that is way more expensive.

    Hey Todd:
    I’m not sure if there is a difference or not but Mercury gave me a part #878492K16 which they said should come with 3 dust covers. They also said you should not have to put a terminator on it. I also considered the new Vessel View 403 which is plug and play but it is very expensive, so the mobile unit was a good addition for the time being.

    289DCDF9-5EF0-436D-9E60-E6DB6FC47FF7.jpeg I pulled up my smartcraft SC5000 installation manual, and the twin engine configuration has a terminator/resistor, image attached. Of course, your configuration might be different, but thought I would upload just in case.

    That certainly is interesting especially when the Merc rep specifically said a terminator was not required. I’ll have to check this further.

    Do you have the smartcraft manual? If not, I can post the full one here. It has about 10 different configurations. The rep might be correct, it’s quite possible that as long as you pull everything plugged into the 4 port junction box and reinsert it into the 6 port junction box, then everything is properly terminated (because it was before). I would go with that theory, if I understand correctly, the terminator just minimizes signal reflections so you will not damage anything.

    Yes, I have the manual for my SC5000 as well. I never really thought of looking in it as the junction box replacement would (hopefully) not affect the SC5000, just give me more accessible ports. The one good thing is that I found (what appears to be) a good source for purchasing the new junction box. Their ad shows it coming with 3 dust covers, as the Merc rep said it should under that order #, and I will probably ask them to send a terminator just in case. Here is a link to the company I am going to speak with this week or next on this purchase if your interested.

    Thanks. Did you cap the port that was left with a purple dust cap or a yellow terminator?
    Thanks
