Sending messages to am LED sign

MrEvans

I'm starting a project to use a stamp module to send strings of data to a LED sign. The stamp will look for input, then on input send a string of data to the LED sign over the serial out, wait 2 minutes, send another string of data, wait 14 minutes, send another string, then loop back and wait for input. The LED sign will accept RS-232 data. It has it's own protocol for the strings.

Has anybody done a project like this?

Is there a project I've missed in the forum?

MrEvans,

Your in luck, Jeff (slotcarz) is working on such a project. His thread is here.

<edit> Hmm, I seem to have scanned too quickly over your post, you seem to not be seeking to create an LED sign, but interface with one. I appologize. I think this may be the thread SPENCE is refering to.</edit>

Try this site. I used this program to get my Beta Brite LED sign working.

It is a very basic program but shows the protocol and displays messages in

several formats. It is a good starting point.

<--- gives himself a mild slap. SPENCE almost always refers to web references. He's likely thinking of

or

I found the Tech Memo #99-0005 that shows how to use a plc to switch messages. This works. I download these text messages with alphanet and then can call them up individually. Now I need to reset the timers, as there are two timers I am using to count down with. The string is huge. I have tried using the protocol in the techmemo, but have had no success.

MrEvans

I checked out the remote_control.net BetabriteHelloworld.exe and it works for text but no timers.

I'll check out the tbitson/weather/bsbb10.bs2 tomorrow.

I have a few things to try.
