6.5 Ethernet Heartbeat data

When the GCAN-212 device working in TCP Server mode and successfully
connects to the PC via Ethernet, if there is no CAN data transmission on a
CAN channel, the receiving window of the network debugging assistant will
display a status message, for example,

" AA 00 FF 00 31 31 39 31 32 31 34 36

33"

, the fifth byte of this heartbeat message indicates the channel number 31

indicates the CAN1 channel, and 32 indicates the CAN2 channel. The last 8
bytes respectively represent the SN number of the device. Since the SN number
at the beginning of the device is always 2, only the last 8 digits are displayed.
The SN number is 219121463. This message is 13 bytes and the sending
