Reprobate2 Posted May 26, 2010 Share Posted May 26, 2010 I recently came into possession of 3 Symon NetBrite signs. They are 24x200 tri-color led signs. The problem is that Symon wants close to $4k for the software for these thing. Requires a server and client apparently. I have connected to the sign via Telnet and was able to make some minor changes, IP addy, Subnet mask, default gateway etc... but cannot make any changes to what the sign displays. I ran nmap against it and found the only open ports are 23 and 700. I have grabbed every bit of free and trial LED sign software I can find and nothing seems to want to interface with the sign. I Even tried a 1gb word list worth of custom commands sent via port 700 and 23 to see if I got any response. Nada.. I am about to buy a PIC board and see if I can just replace the controller, but I thought I'd see if anyone has successfully hacked one of these signs, or any sign from Symon for that matter.
