GPS Speed Sensor Cable Definition

RED: Power +, DC 8~32V (please connect a resistor like the image above)
BLACK: Ground
GREEN: Speed Pulse Signal Output +
BIUE: Speed Pulse Signal Output -

Please connect a GREEN or BLUE cable (one of the two) to your current Speedometer/odometer/tachograph.

GPS Antenna: Securely fasten the GPS antenna, preferably outdoors (ar inside front windscreen) so that it has a clear view of the sky to pick up satellite signals.

Tips: How to program the speed ratio to fit your current speedometer/odometer/tachograph?

Connect the speed signal (Green or Blue) cable with your device.
Power on GS202 GPS speed sensor and speedometer.
Press the button via the hole, and hold on for 10 seconds, you will see the needle start running.
Release the button, and wait for 5 seconds.
Hold on to the button again, the needle will run in the opposite direction.
Use steps 3~5, to make the needle point at 60km/h, then release the button and power.
Setting is done.
It fits the speed ratio range is 1~20,000ppk.
