Serial Logic Level
Communication hardware and device wiring to connect MoTeC products with a Serial Logic Level port to the PC.
In order to update the software in the ECU or to enter an upgrade password a Software Update Unit (SUU) is required.
Applicable MoTeC Products
M4 with serial number less than 3000
M48
M8
PC Connection
MoTeC provides solutions to connect the device to the PC's serial port or USB port. The simplest connection method is via the PC's serial port, however many modern computers do not have a serial port, in this case use the USB connection method.
Connecting to the PC's USB Port
Create a serial port, using a USB to RS232 serial adapter. Then follow the connection method for a PC with a serial port.

Connecting to the PC's Serial Port
Use either a PC Interface cable (PCI cable) or a Computer Interface Module (CIM).
- PCI cable
The PCI cable contains electronics in the ECU end of the cable to convert the ECU signals to signals compatible with the serial port on the PC
- CIM module
The CIM module is normally installed in the vehicle. This places the electronics in the vehicle rather than in the cable which has the advantage of providing the correct signals to connect directly to a dash or data logger as well as providing a connection point for a PC. The CIM module can be wired to suit different PC connection cables. Typically it is wired to suit a standard serial cable or a MoTeC 4 pin cable.
The CIM is also available as a kit with all the cables necessary to connect to a PC and the ECU including an intermediate D9 connector to allow connection of an SUU.

DEVICE WIRING
Suitable for PCI Cable
For M8, the PCI cable connects directly to the connector on the ECU.
For the M4 or the M48 ECUs, a mating connector must be wired to the ECU connector to provide a connection point for the PCI cable.

Suitable for CIM Module
The CIM module can be wired to suit different PC connection cables. Typically it is wired to suit a standard serial cable or a MoTeC 4 pin cable.
The CIM can be wired directly to the ECU or it can be wired to connect to the normal D9 connector as described for the PCI cable above. The latter has the advantage of allowing a Software Update Unit (SUU) to be installed when the ECU software needs updating.
Software Update UNIT
In order to update the software in the device, or to enter an upgrade password a Software Update Unit (SUU) is required.
