    Resolved [RESOLVED] Serial Port Coms and External LED Display

    Hi all

    I hope this is the correct place to post this, if not, I apologise.

    I'm trying to write a VB2005 app that will communicate via serial port with two external LED displays. While I can do the VB side of things, I'm completely stumped by the communications protocols used to talk with the displays

    Can anyone help me out and try and decipher the protocols so that I know what strings to send to the displays? (pdf attached).

    The company in question (Polycomp) will quiet happily write me something for an extortionate price, but that's as far as they will go

    Thanks in advance

    Andy
