Really you think more than 4 dosing pumps? Maybe when its all said I done I can add more. The expansion hub will run more its all about the GUI really.
I hear you on the USB plugs, what scares me is people mixing up the plugs. In the beginning I did play with RJ11's for the display and it wasn't good. I wanted to use it because the plug disappears. Using the factory phone cords no current passes through, the wire is so thin. I tried using cat5 cable on the RJ11 connectors but the wire was to thick to put in the connector so I wan't able to get it working over 6ft in length. Maybe there are special RJ11's that accept bigger wire I don't know.
In the end I would prefer waterproof type connectors but cost is way to much that's why I choose USB, easy to get, cheap, small, easy to work with SMD means smaller cheaper boards and fairly reliable. With a total of 27 ports if jacks cost $3 each and connectors $4 each that's nearly $200 just for connections. I'm almost forced to use some kind of USB style connector because of cost. I tried micro USB but they're to fragile.
I know that's a lot of ports but I think its the best way in the end. For the expansion hub it doesn't cost much more to make it with 14 ports than it does with 6 ports. I don't want to sell all kinds of modules for big bucks and with the single expansion hub everything and anything can be connected. My hope is a person doesn't have to spend a day figuring out what modules and addons are needed to run everything. But yeah downside is a person can get confused on the ports because there are so many. The expansion hub will have customization using jumpers on the board for maximim flexibility and in the GUI on some ports you'll be able to select what the port controls. So a port won't necessary be stuck to a single job or piece of equipment. I'm trying to put a lot of thought into this I hope I'm not missing any equipment.
I've been getting lots of guidance from people which is great, I can use all I can get. I want to make sure I get this right.
