Appendix G: ECU to SDL Wiring (RS232)
The following details the methods for connecting the various MoTeC ECUs to
the SDL via RS232. In all cases this is done using the serial data stream
generated by the Telemetry function of each ECU.
In the case of the M800, M880 and M4e the SDL may be directly wired to the
ECU because these ECUs use RS232 interface levels. On the M48, M4 (pre
M4e) and the M8 a Computer Interface Module (CIM) or a PCI cable is
required to convert the signals to RS232.

Note that the data to the SDL will be interrupted while a PC is connected
(DOS software only)
Note that the 9 pin connector is not used if using the Windows Calibration
software.
Note that data may be sent to the SDL via the CAN bus as an alternative to
the serial connection.
