MoTeC SDL - Manual (Page 22)

20 Installation
Note that if wired to an Analog Voltage input an external pull-up resistor must
be connected between the input pin and the 5V sensor supply.
External Lights
All lights including the Shift Lights & Warning Lights must be wired externally.
This allows a choice of lights and allows the lights to be placed in the optimum
position.
The MoTeC Shift Light Module (SLM) can be used for this purpose, otherwise
LEDs or LED arrays can be used.
SLM
The SLM includes 8 LEDs that can be programmed to any colour and can be
used for both warning lights and multiple shift lights plus many other
functions.
The SLM is connected to the SDL via the CAN bus so it does not occupy any
of the auxiliary outputs.
LEDs
LEDs may be wired to any of the four Auxiliary Outputs.
The LEDs must be wired between one of the Auxiliary Outputs and battery
positive and must include a current limiting resistor.
Thermocouples
Thermocouples must be wired to the SDL via a thermocouple amplifier.
The MoTeC Thermocouple Amplifier (TCA) may be used with K Type
thermocouples and may be connected to either the Analog Voltage or Analog
Temperature inputs of the SDL.
Connecting to a MoTeC ECU
An ECU may be connected to the SDL which will make information in the
ECU available to the SDL for display or logging or any other purpose.
MoTeC M400/M600/M800/M880 ECUs may be connected via CAN or via
RS232.
