CAN (Controller Area Network) Communications
This protocol enables communication between all devices connected to the
same bus. The CAN bus allows communicating at high speeds. The C185 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 devices communicating over CAN:
o
'Hundred series' ECU: M400, M600, M800, M880
o
Shift Light Module: SLM
o
Lambda meters: LTC, PLM
o
Expanders and input modules: E888/E816, VIM
o
Displays:
SDL
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
M4, M48 ECUs
o
Radio telemetry device
o
Global positioning system: GPS
Note: The C185 can communicate with devices for which it has the
appropriate communications protocol defined. For other devices, users can
define their own custom communication settings.
