How to configure ReXgen data logger to data.

Bus Options

This option is used to configure the CAN bus and LIN bus settings, such as:

• CAN/CAN FD bus speed

• LIN Bus settings

• Silent mode settings

• Bit timings

Tool Bar

The toolbar holds the various functions that can be added to the CAN Bus.

The user application can transmit a CAN Message to ReXgen to trigger the following responses:

1) Current Firmware version of the ReXgen.

2) ReXgen should confirm that it is configured, has a configuration version, and has an active configuration.

3) Send the serial number of the ReXgen.

4) Send the RTC Date & time.

Format of the Transmitted message:

FW_TYPE 0-Release, 1-alpha, 2-beta, 3-pre release

FW_BRANCH 0 -Main branch
