Cable length clarification with examples

[ToLearn]

The new user guide states that, "The AquaBus can be a total of 200' in length"

First question, when I look at that line in Adobe it looks like 200', then when I copy and paste it into Google Chrome it pastes it as 200". We are talking 200'(two hundred feet) right? Not 200" (two hundred inches)?

Second question define total.

Is it that if have the head unit 10' from the Apex base, a PM1 50' from the Apex base, a PM2 50' from the Apex base, an EB8 50' from the base module, and you want to put a second SL1 module 120' away from the Apex module you can?
(Does it matter how many feet of cable are in the total system as long as you stay under 200' total in one stretch between equipment?) [280' total length of cable in example, longest length 120']

or

If you have four modules each with 50' of cable running to them you can not add any more modules or you will exceed the amount of total cable aloud in the system.

The new and improved Neptune Manual says...

"The entire length of the AquaBus should be kept to a maximum of 200 feet."

... and I read their meaning of the term "AquaBus" to mean the communication link between modules/energy bars, not the cable itself.

So I'd take it to mean the total of all the cables should be less than 200 feet. Probably best to confirm direct with Neptune.

Thanks Kurt. I e-mailed them as well. My brain procsess things differently sometimes so it's best to hear things from more the one source worded multiple ways.

I have several tanks I want to controll in one room and another far away in a second room. Hoping to run cables to the second room around the edge of the room vs a long trip cord in the middle of the room.

Not sure if I should share a personal e-mail between me and Neptune, but:

"It is 200 feet total length, so if you do it as suggested you will be overthis limit. I do not suspect that it will cause any problems however as thebus transceivers we are using are designed to work with over 5000' ofwiring. We have conservatively speced it at 200' to ensure that there arenot any issues."

Seems like either way should be ok. I'll be trying this out soon as I can afford some long USB cables to wrap around the room. Looks like no trip cords for me.

Thanks for relaying their response. At least it'll be here for others to see if they have the same question.

My thoughts exactly.
