Appendix J: ECU to ACL Wiring (RS232)
The following details the methods for connecting the various MoTeC ECUs to
the ACL 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 ACL 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 The data to the ACL will be interrupted while a PC is connected (DOS
software only)
Note The 9 pin connector is not used if using the Windows Calibration
software.
Note Data may be sent to the ACL via the CAN bus as an alternative to the
serial connection.
