CAN settings
Command format
CanRegime Mode,BaudRate,TimeOut, DoNotCleanAfterTimeOut
Parameters
Mode
– operating mode:
0 – CAN-interface is off and is not used;
1 – CAN-bus scanner;
2 – standard FMS filter;
3 – user filter29 bit;
4 – user filter 11 bit
BaudRate
– data bus rate. It must be the same as the vehicle data bus rate. It can
have the following values: from 10000 up to 500000. Typical valuations: 62500,
125000, 250000, 500000.
TimeOut
– measured in msec. For CAN_SCANER mode it is response latency. If it
is too small, not all bus messages will be received. The recommended time for
CAN_SCANER is 2000 msec. For all the rest modes it is time to receive at least one
message otherwise the value will be set to zero.
DoNotCleanAfterTimeOut
– data should not be set to zero by disconnecting CAN-
bus.
Explanation
General CAN-bus control.
Example
Example: switching on scanner for a 250000 b/sec bus with the message (answer)
latency equal to 2 sec.
Request: CanRegime 1,250000,2000
Reply:
CANREG: Mode=1,BaudRate=250000,TimeOut=2000;
DoNotCleanAfterTimeOut=0;
Command format
ActiveCAN OnOff
Parameters
OnOff
– operating mode:
0 – passive mode: packets receiving confirmations are not sent to the CAN-bus. It
is a safe mode of operation. It does not interfere with the on-board equipment;
1 – active mode: packets receiving confirmations are sent to the CAN-bus.
Explanation
Control of packets confirmation sending to the CAN-bus.
Confirmation sending may be necessary by connection to the troubleshooting
socket if the data cannot be read in passive mode.
Example
Request: ActiveCAN 1
