I'm in charge of our PWD event this year and am having an issue with interfacing with the timer.
The setup I've tried is to set up a virtual comm port using a USB to 9 pin serial dongle. The Grand Prix software, after installing the driver for the dongle, did recognize it as COM4 . I then added on a 9-pin to 25-pin adapter to attach to the 25-pin timer cable.
I set the Grand Prix software to ready and haven't been able to poll any times.
Anybody have experience with this and/or suggestions ?

Re: 25-pin to USB timer help !
If your system is using a 25 pin connector, it is most likely a parallel port system, not a serial port one. GPRM V7 and above only supports serial port timing systems.
There is no easy way to convert a parallel port system to work on the serial port, without giving it a brain (processor). Parallel port systems are dumb (no brains) where the computer does the timing based on inputs from the sensors. Serial port systems are smart. They contain a processor to do the timing and then transmit the results to the computer.
