M4/M48 Operation
This section describes how to use the MDD with a MoTeC M4 or M48 ECU.
The MDD is capable of receiving and displaying data transmitted from a
MoTeC M4 or M48 ECU via a serial link. A correctly configured M4/48 will be
automatically detected when the MDD is powered up.
There are two modes of operation “User” and “Tuning”, each mode has a
number of fixed display layouts as described later in this section.
A momentary action switch wired to the MDD is used to move between the
display modes and layouts.
M4/M48 Version
For compatibility with MDD V1.18, the M4 or M48 must be running version
6.21b or later firmware.
ECU Configuration
The M4/M48 ECU musty be configured with the “Telemetry Data Set” set to 5
and the “Telemetry Baud Rate” set to 9601.
Note: If an ADL present on the same CAN bus as the MDD it must not be
configured to transmit to the MDD.
Connections
The MDD is connected to the M4 ECU or M48 ECU via a serial link.
For wiring details see Appendix E: Wiring to M4 / M48.
