Hello,
I was looking for some information on how to hack a wireless digital sign. Not like a road sign, more like at a business or something. I know that the sign is edited wirelessly. From what I gather, there is basically an internet server dedicated only to editing said sign.
I am looking for info on how to detect (assuming its hidden) and access this network. If I can do this, then how can I proceed with editing the sign to my liking?
Thanks for any help you can offer me.

Re: hacking a wireless sign
Not really familiar with this. I'm sure you can find some information by searching for companies that actually offer these type of "editable" sign services. Figure out from them how their servers work and work from there.
The first step would be to figure out the terminology though.

happy hacking.

Re: hacking a wireless sign
Ok I did a little recon this evening and found out that this particular sign is from Daktronics. Specifically I believe it is this one or something very similar. http://www.daktronics.com/ProductsServi ... fault.aspx

Re: hacking a wireless sign
There are several model lines available. If the sign is from Daktonics, it is probably using this, based on your initial description. I would also venture a guess that all of their systems have similar communication methods, as demonstrated in this spec sheet. (So you don't have to open the pdf:)
Communications protocol: NTCIP
Communications options: Dial-up, Cellular, Fiber, Ethernet, Direct and Radio
Assuming these displays all work similar to the Daktonics one we can be pretty sure it's using some form of the NTCIP standard. The problem is that you're now dealing with a huge range of unknowns. I've been skimming through the document here (It's 2 MB, beware). In section 12 of chapter 3 it begins breaking NTCIP down, so that's something you should check out. Hell, actually just read all of chapter 3. I'll assume that you're going to read it since you're the one who's interested, so I won't summarize a bunch of crap here. My brain is about to explode anyway so I'm taking a break.
Check out Control systems and fixed installation systems as well. Determining what specific kind of display system is in use may help narrow things down.
