MoTeC DBW-4 7 Introduction
Communications
CAN
The CAN bus is used for PC communications during testing, calibration and firmware upgrades, and for
communicating to the ECU.
The following data is transmitted by the DBW-4 at 200Hz:
•
Measured Values 1 & 2 for each PID (AV1-AV8)
• Measured Value 1 with PID diagnostic information.
The following data is transmitted by the DBW-4 at 50Hz:
•
Output driver faults
• Internal temperature
• Internal voltages (-5v, 8vAux, 5vAux, Vbat, 4.5v)
• DBW-4 status flags
• DBW-4 firmware version
The following data is received by the DBW-4 from the ECU:
•
PID1 to PID 4 set points
Firmware Upgrades
At times MoTeC may release firmware upgrades for the DBW-4 Units. Upgrades are performed over the CAN bus
using a MoTeC CAN cable and the MoTec DBW-4 Manager Software. See the section DBW-4 Configuration for
more information. Currently the MoTec DBW-4 Manager Software does not support the MoTeC UTC.
