Sign board in question is a LaBelle industries express 152 (of around
1989 vintage) that works, but is missing the keyboard and a hunt for a replacement has been futile. I found a wired keyboard from the same manufacturer, but there is no place to plug it into the sign. The IR receiver in the sign is a philips TDA3047 that uses a 36Khz input signal. Is it safe to assume I'd possibly be able to somehow program this using philips IR protocol using a universal remote? If not, what options do I have aside from tossing this into the trash? I opened up the wired keyboard, and it's a simple switch matrix setup with 20 pin connector. Thanks,Alex
