It is one wire communication. The voltage level is 18VDC. What you see in that picture the output from a RS-232 IC. I can identify the start/stop and know what each piece of data is. The problem is, I have to do it with my oscilloscope and eyes as opposed to using a PIC to interpret it.

Each bit is 500uS. The high/low within the 500uS bit is predetermined. In other words, it may be 200uS off and 300uS on or 400uS on and 100uS off but I know before the packets starts. The entire packet is 100mS long.

What is the best way to get this information to a PIC where I can log it instead of staring at my oscilloscope?
