FIGURE 3-4: TRANSMIT WINDOW
The Transmit window allows the user to interact with other nodes on the CAN BUS by
transmitting messages. The user is able to enter any ID (Extended or Standard), DLC
or DATA Bytes combination for single message transmittal. The transmit window also
allows the user to transmit a maximum of nine separate and unique messages either
periodically or periodically with a limited “repeat” mode. When using the limited repeat
mode, the message will be sent out at the periodic rate for a number of “repeat” times.
