After sending a transmit message to the HDV100A3 you will get the confirmation message if the checksum is correct. A transmit complete message is sent to the PC after the device successfully transmits the message to the J1708 bus. A second message should not be sent to the device before confirming that the first message has been sent. The transmit confirmation is formatted as follows:
Byte | Byte Value | Byte Function |
Number | (hex) |
|
1 | 01 | Start of frame |
2 | 01 | Number of control bytes |
3 | 09 | ID bytes 9 = transmit OK |
8 | 00 | Number of data bytes |
9 | 0B | Checksum |
