MoTeC
Installation
21
The MoTeC M4, M48 & M8 ECUs must be connected via RS232.
Connection via RS232
The telemetry feature of the MoTeC ECU is used to send data to the SDL via
an RS232 connection.
See Appendix G: ECU to SDL Wiring (RS232) for wiring details.
ECU Setup
The ECU ‘Telemetry Set’ and ‘Telemetry Baud Rate’ should be selected to
suit an RS232 communications template supported by the SDL.
SDL Setup
Setup for the SDL is done in the ‘Inputs | Communications’ setup screen.
Select a communications template that matches the ECU type and ECU
telemetry set.
In the displayed channel list, check those channels that you wish to receive in
the SDL
Interruption of the Data
Note that when using RS232, the data flow to the SDL will be interrupted
while a computer is connected to the ECU and will not resume for up to 10
seconds after the computer has been unplugged. During this period any value
that comes from the ECU, such as RPM or Engine Temperature will not be
updated and will normally be displayed as zero. On later versions of the ECU
software the 10 second delay is reduced to 1 second.
Connection via CAN
The SDL and ECU must be connected on the same CAN bus.
See Appendix H: CAN Wiring for wiring details.
ECU Setup
Set the ‘CAN Data Set’ to a set supported by the SDL (normally set 1).
The ‘CAN Address’ must also be set. Normal value for SDL is 1520. This is a
decimal value that corresponds to a hexadecimal value of 0x5F0 in the SDL.
