14. YELLOW FLAG LIGHT SETUP
Optional Integration
The existing yellow flag system utilized in the Pirelli World
Challenge series already has the capability to integrate and
communicate directly with almost any data logger or display
including the entire range of MoTeC loggers. The MSE box has
an external digital output which signals when the yellow flag light
system activates. Similar to the output which drives their yellow
light, this digital output wire is ran directly into an input pin in the
logger. A yellow flag channel can then be logged within the data
allowing for easy determination of when the in-car yellow flag light
system is active. It can also be used to notify the driver via an
Alarm on the display AND activate the driver's shift lights by flashing them yellow. The driver's shift
lights are often in better than the current small remote mounted light simply because they are often
placed more in line with the driver's view and the driver is constantly watching them.
All new MSE boxes and wiring harnesses will have an external trigger wire available. Older
existing systems will need to be upgraded by MSE. Please contact Bruce Natvig at 765-316-3399 or at

Below is an example of setting up the yellow flag wire onto the SPD3 input pin with a calibration
setting of low volts = active. This channel may then be used to create an alarm and under the SLM
setup to activate lights. It should also be logged at 10 Hz.
