I am investigating if the GAZ4 display board will interface directly with the CP 705 via the serial port on the Tag. We are using Copper Spur software for club races. Is this possible and if it is, what are the set up parameters for the GAZ4. Thanks for any help.

You have to change the baud rate of the GAZ4 to 9600 to accept data from the TAG 705. The circuit board needs to have a jumper added. You would then need to make a parallel cable that would allow the display and software to receive data simultaneously.
