Basic function:

The EasyLap timing system operates with the transmission of infrared light, like a ordinary remote control of TV or VCD. This means the transponder sends the information signal via infrared light to the bridge receivers. This signal is processed by the interface and then delivered to the PC software. So it is absolutely necessary for the transponder to have a clear line of sight with the bridge receiver. To ensure this, place the transponder just below the window of the body. The receiver modules can be placed one a bridge above the track. So it is possible to drive with as much cars as you like at the same time.


Bridge receiver modules:

In the EasyLap timing system kit there are 4 receiver modules included. But how much modules you need depends on your track width and the height of your bridge. Following values for the beginner are recommended:

Height of the bridge:50-100cm

Distance between the receiver modules: about 30cm


For example if you have a track width of 150cm and you place the receiver modules with a distance of 30cm from each other on the bridge, you need 4 receiver modules.

Basically the higher the bridge, the larger the reception range of the receiver module and the less modules are needed. But the height of the bridge should also not be too high because the signal strength decreases with the height.

If you have mounted the receiver modules on the bridge you have to connect them together with the delivered flat cable. This flat cable has 5 connectors. 4 connectors to the receiver modules and 1 connector to the interface. If your track need to add receiver module as you want.



If the bridge (not included) is ready, you can connect the interface with the flat cable to the receiver modules. To avoid interferences the distance between the interface and the bridge should be as short as possible.

On the interface you find a Mini-USB connector for the communication with the PC.

When connected, the red Power-LED should light up. At initial installation, this process can take a few seconds, the driver is installed automatically. When putting on also the blue Action-LED should flash briefly.



When you mount the transponder inside your model you have to search for a position where the transponder has direct visibility with the bridge. Otherwise the infrared signal is not delivered to the receiver modules. The transponder can be connected directly to the radio receiver in the model. If you use a receiver pack (for example in 1/10 RC nitro cars)you should only use 4-5 cell receiver packs.



First operation

 If the system is ready, you can install the Zround software on your PC. The setup files of Zround program can be download this link below.

Adjust Lap counter setting:


Now you should adjust the right Lap counter model. This configure page you can choose when clicked Optionsbutton on the top menu. Lap counter model you have to choose EasyLap.




 You now have to choose USB option and let Active Easylap option checked. Once these settings are done click on the connect button. You should now see Easylap comport opened.
