cb-625 Serial Interface

The Serial Interface connects the cb-625 to a standard PC serial port. The interface costs £8.95 but for those of you who can't wait or have an electrical bent this is what you will get built into a DB-25 plug housing.

This is a developement release with help and will self install. We think this does most things you want and can write a spread-sheet friendly comma delimited file incase you really want to get mathematical.

If you really want to go it yourself you need to know:
The cb-625 interface sends at 9600 baud, 8 databits, 1 stop bit, no parity.
The RTS line must be set active (+ve) and the transmit data left inactive (-ve)
The data consists of a 4 digit ascii decimal number, zero filled with the most significant digit first followed by a carriage return (0DH) and a line feed (0AH)
This is the number of clock cycles at 4MHz taken for the pellet to travel the 60mm gap between the two sensors.
