1.2.3 Listen only mode
This mode only supports tM-7530, tM-7530A and tM-7565, and be used to monitor
the messages of the CAN network without converting the message, so it will not send
any CAN messages to the CAN network, such as Error Frame or ACK signal.
For example, there are two CAN devices (such as I-7530 and I-7565-H2) in the
communicating, and the user want to obtain CAN messages between CAN devices, the
user can set the tM-7565 to listen only modee, and then connect the CAN side into the
CAN network, and connect the UART side to the PC for monitoring.
If the user uses a common communication port (COM port) testing software to
monitor in the PC as shown in figure 1.2.3.1, and will get the UART command string.
If the user uses the testing interface of VxCAN Utility to monitor in the PC as
shown in figure 1.2.3.2, and will get CAN messages.
Among them, if the user need to use the COM port testing software, please refer to
section 5.7. If the user need to use the testing interface of VxCAN Utility, please refer to
section 3.6.
