Layer 2 communication (11/29 bit ID) mode

When using the 11 bit / 29 bit CAN-ID Layer 2 Mode, the outline of the communication setting procedure is as
follows.



For further information on BFMs, refer to Chapter 5



For further information on data transfer location and configuration, refer to Chapter 7



For further information of the CIF, refer to Chapter 9



For example program, refer to Chapter 11

Step 1

Set the following:

Refer to Chapter 5

- Function mode (BFM #21)

Step 2

1) Set the following:

Refer to Chapter 5

- Baud rate (BFM #24)

- Reset module (BFM #25 = K1)

- FROM/TO Watchdog Timer (BFM #26)

2) Reset module

Refer to Chapter 5

- BFM #25 = K1
OR
- Power cycle

Step 3

Set the following:

Refer to Chapter 7 and Chapter 8

- Tx/Rx user messages BFM #1100 to #1267, #100 to #394 (#395 to #399 not used)
- RUN>STOP messages #1900 to #1927

Step 4

Save Configuration to FLASH ROM (BFM #22 bit 1 = ON)

Refer to Chapter 5

Step 5

Set FX

-J1939 to online mode (BFM #25 bit 4 = ON)

Refer to Chapter 5

Step 6

The FX

-J1939 is exchanging data with the network

- The user messages are exchanged with the remote nodes.
- Acyclic Command Interface services are available
- Configured RUN>STOP messages are transmitted in case of
