Reverse Engineering the RS485 protocol

Well this weekend I had quite an adventure with RS485. I ran into a couple issues on the way. One was Identifying the baud rate of what your vampire tapping into. One way is to use an Oscilloscope and find the shortest pause and calculate the baud rate from that. Take the shortest pulse, then measure it in Microseconds (US aka 10^-5 in scientific notation aka 0.00000X). Take that value then plug it in here, (1 / 0.000026 = 38461.53…) there for 38461 is your baud rate… where 26 Microseconds is your shortest pulse. An example on how to eye …

CVC22350 – Traffic Trial Unsafe Speed, Convicted.

UPDATE: Opening Brief filed, Preparing for Battle http://controllingtheinter.net/2018/02/27/traffic-court-cvc-22350-basic-speed-law-continued-appellants-opening-brief/ So, I’ll be posting as I go through this process, I am working on getting this document for anyone who cares to take interest in their own traffic adventures. So I showed outside the trial court and I recognized the officer standing about. I peeked over and saw that he didn’t have any document on him other than one sheet of paper which was a citation he gave me during the stop. So instead of talking to him outside bartering for a plea, I ended up planning to proceed to trial. The …
