MoTeC ACL VIM - Manual (Page 32)

28 Operation
allows all connected devices to communicate with each other. The CAN bus
also has the advantage of being able to communicate at high speeds.
MoTeC products that use CAN for intercommunication include M400 / M600 /
M800 / M880 engine management systems, BR2 beacon receiver, PLM
Lambda meter, VIM input module, SLM shift light module, SDL and ADL2
displays, RTC real time clock, SDC and MDC diff controllers, and MDD mini
display.
Note 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.
Serial Communications Ports
The serial communications ports can be used to receive data from an ECU, a
GPS or a similar device with a compatible communications port. They can
also be used to transmit data to other devices such as a radio telemetry
device.
The port labelled RS232-1 will only send and receive RS232 data, the port
labelled RS422 supports both RS422 and RS485 in addition to RS232 data.
Note The ACL can only communicate with devices for which it has the
appropriate communications protocol defined.
