SDL3 Data Logger to ECU wiring (RS232)
The following details the methods for connecting the Data Logger to the
various MoTeC ECUs 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 Data Logger 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.
M800 / M880
Note:
•
The data to the Data Logger will be interrupted while a PC is connected
(DOS software only)
•
The 9 pin connector is not required, if using the Windows calibration
software.
•
Data may be sent to the Data Logger via the CAN bus as an alternative
to the serial connection.
M4e
Note:
•
Older M4 ECUs require a different connection method
•
The data to the Data Logger will be interrupted while a PC is connected.
