I mean do they do anything with the IR signal beyond simple modulation? -- Reply in group, but if emailing add one more zero, and remove the last word. |

I mean do they do anything with the IR signal beyond simple modulation? This is a pair I was going to hack, but they're Genie brand, and my opener is Liftmaster. So I ordered two pair of the Liftmaster variety, and will hack my circuit to match the Liftmaster signal. What is surprising is the lack of much in the way of patents... proprietary ASIC's ??? ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice 480)460-2350 Fax: Available upon request | Brass Rat || E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.
