Computer Connection Mode 

- This mode becomes active once a back-and-forth 

communication has been established between GPRM (Grand Prix Race Manager) 

software and the timer. To connect to GPRM software, go to the software Hardware 

Settings page and make sure “The Champ” radio button is selected. Click on the 

software “Start Testing” button to connect the timer to the software. Run a test race on 

the Hardware Settings page.  

 

Note:

 Once communication with GPRM has been established, all lanes will be turned 

back on if previously masked (see #8 above). You will now use the GPRM software to 

mask (turn off) the lanes. The timer will also be in No Timeout Mode (see #7 above) 

and will not reset on its own. You can reset the timer from within the software or by 

using the reset button.

  

 

10. 

When using a Serial to USB Adapter - 

If you are using a Serial to USB Adapter to connect your Champ Timer to a laptop or 

other computer, be sure to install the drivers for your USB Adapter. Your timer will not 

communicate with the computer if you do not have the drivers installed for the Serial to 

USB Adapter. If a driver disc was not included with your Serial to USB Adapter, you 

can download a new version from the manufacturer’s web site. 

Note:

 The adapter driver might download and install automatically if you are already 

connected to the internet when you plug the adapter into a USB port on your 

computer. 

 

 

TROUBLESHOOTING:    

 

If you have a “n” in one or more lanes

, this means that the lower sensor cannot see 

the infrared LED light shining down on the track from the upper part of the timer. 

Check to see if the lower sensors on the sensor bar are aligned with the sensor holes 

in the track. Check to make sure that no debris is blocking the sensor. Look 

at the infrared LED light that shines down on to the track and make sure it is pointing 

straight down and did not get tipped to one side. The LED can be gently repositioned if 

needed. The infrared light from the upper LEDs is invisible. 

 

If the first car is showing a “0.0000” elapsed time on a race

, the timer is not 

receiving the start signal from the start gate switch. Check to make sure the start gate 

switch/reset cable is plugged in all the way. Also, check to make sure the start gate 

switch lever is fully depressed and that you can hear the start gate switch “click” when 

the start gate is put up into the “ready to race” position. You may need to slightly bend 

the metal lever of the start gate switch down towards the floor so that it contacts the 

start gate sooner.  

 

If you are getting 9.9999 for all the times for your cars,

 you may have the start 

gate switch hooked up incorrectly. See the diagram shown on page 6. 

 

The middle connection of the start gate switch should not be connected, see the 

diagram shown on page 6.
