Does anyone have any thoughts on interfacing a Ramsey model RXD443A wireless RF Link to a Leopard controller. The output from the receiver is 4 bit digital. 300-600 foot range on 433 MHz makes it interesting for car applications etc.

Paul, I ust got the file you sent me. This looks a lot like the RF circuits used for ceiling fan remotes. The address setting is to avoid interference between several units in the same house/area. The 4 bit encoding scheme is what allows you to encode up to 16 buttons (or commands) between the transmitter and receiver. Something like that could be used with a SECU16, using 4 inputs to read the 4 bits and decode the command being sent. The best way to read such a group of inputs would be by reading the module data directly (extended variable) to interpret the bit pattern in one single command.

I think I will pursue trying to run the receiver into your analog inputs. What a neat new Bobcat design this could make, wow! I want to include my car into my X-10 software. Like opening garage doors when I come up the driveway without button pushing. Close the garage door when I open the car door etc. I have twin sensors on the driveway now so I can tell if someone is coming up or down the driveway.
A new twist here for interfacing RF to my Leopard. I really want to get my car to automatically open my garage doors, turn on lights etc. with no button pushes. I think I have found and extremly simple and inexpensive way yo do it. I have literally taped a 12VDC bulb to a "Eagle Eye" MS14A. It is a Ir detector and is wireless. I'm going to connect the bulb to my brake lights in the car and I think be home free! It works very well on the bench so far. Off to start writing software for it!
