CAN (Controller Area Network) Communications
This protocol enables communication between all devices connected to the
same bus. The CAN bus allows for communicating at high speeds. The CDL3
has two independent CAN communications ports that can be connected to
other devices with a compatible CAN port. The bus speed for each interface
can be set independently.
Typical MoTeC devices communicating over CAN:
o
M84 and 'Hundred Series' ECUs: M400, M600, M800, M880
o
Shift Light Module: SLM, SLM-C
o
Lambda meters: LTCs, PLM
o
Expanders and input modules: E888, PDM
o
Displays: SDL3
o
Beacon receiver: BR2
These devices communicate at 1 Mbit/sec, so any other devices connected
on the CAN bus must also communicate at 1 Mbit/sec. If a device
communicates at another speed, it should be wired to the other CAN bus, and
the speed of that CAN bus must be set to match the speed of the device.
RS232 Serial Communications
This is a one to one protocol, communicating from one device to one other
device. Typical devices communicating over RS232:
o
MoTeC M4, M48 ECUs
o
Radio telemetry device
o
Global positioning system: GPS
Note:
The Dash Logger can only communicate with devices for which it has
the appropriate communications protocol defined.
