LIN : Local Interconnect Network - neoVI
Main
A pplies to
neoVI Blue, neoVI Red, neoVI FIRE, and neoVI
neoVI supports com m unication on LIN (Local Interconnect Network ).
O nce detecting a proper Sync Break and Sync field, the neoVI will wait for the Msg Identifier field. The m essage reception will begin with the Msg ID field. The neoVI will receive the entire m essage according to the LIN spec.
After receiving the m essage error free, the neoVI will send the received m essage to the host starting with the Msg ID field.
If there are any errors neoVI will report the errors back to the host. Table 1 below lists the errors check ed for by the neoVI device.
neoVI supports acting as a m onitor, m aster, and slave.
Enabling LIN is done in the Hardware Ex plorer. For neoVI Blue LIN is enabled under the ISO 9141/KWord 2K/UART/LIN options. Set the Mode to "LIN Mode" and the "Rx Transceiver" to LIN. Also m ak e sure the baud rate is
correct for your network (Figure 1).

Figure 1 -LIN mode is entered via the neoVI Explorer.
Yellow is done in Hardware Ex plorer by Selecting the channel under network Enables and then setting the proper baud rate for that LIN channel (Figure 2)
Figure 2 -LIN mode is enabled via the neoVI 3G Explorer.
