Hardwired switches
External buttons can be hard wired into the dash through the switch inputs and DIGITAL
GROUND (pin 40). However, only four switch inputs are available so there will be limited
functionality.
The relevant special items “SW-X” must be assigned to their corresponding inputs.
4 Way keypad
The D5 also allows the option of your own 4 way setup using a single input pin and ground
with the keys ‘Left,’ ‘Right,’ ‘OK’ and ‘Down.’ This will allow navigation and the ability to change
anything on the
page and is ideal for switches on a steering wheel. For custom display
changes the Life Racing D5 Keypad or PC application is needed.
Each button should be a normally open momentary switch connecting SENSOR GROUND (pin
19) to the same ANALOGUE INPUT pin (1-4 only) through different value resistors.
The special item “AN-KEYPAD4” must be assigned to the analogue input used.

CAN inputs
An individual CAN message can be used for every switch input. Create the items and ensure
they are used to define the CAN inputs under special items. Any non-zero value will be
considered a key press.
The relevant special items “CAN-X” must be assigned to their corresponding items.

Lap Beacon
The lap beacon is used for lap times and in calculations such as fuel consumption. It can be
received either directly into one of the four switch inputs or over CAN. Both methods require
*Note*
If directly connecting, it is recommended that the beacon is duel wired to both the Dash and
ECU.
