CDL3 Dash Logger to ECU wiring (RS232)
The following details the methods for connecting the Data Logger to 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.
M4e
Note:
• Older M4 ECUs require a different connection method
• The data to the Dash Logger will be interrupted while a PC is connected.
M48, M4 (pre M4e) and M8
The M48, M8 and M4 (pre M4e) require the use of a CIM module or a PCI
Cable to convert the logic level signals used by these ECUs into RS232
levels.
Using a CIM Module
Contact MoTeC for the CIM module drawing for full wiring details.
Note:
• The data stream to the Dash Logger will be interrupted while a PC is
connected.
