UART/ISO9141/KW2K/LIN - neoVI
Main

Applies to
neoVI Blue, neoVI Red, neoVI FIRE, and neoVI Yellow

The neoVI supports a UART/ISO9141/Keyword 2000/LIN network. This network is basically a UART/SCI unit with a hardware level shifter (Figure 1). There are many variants of a UART network schemes which can be monitored with this network.

As shown in figure 1, the network has a pull up voltage for the K and L line of VBATT.  In neoVI Blue, the pull up resistor can also be changed.  Please see the Hardware Settings topic for more information on changing these items. Please note that the factory default pull up voltage is VBATT with a pull up resistor of 510 ohms.

Figure 1 - neoVI implements a hardware level shifter for each K and L line.

As shown in figure 2, there are many settings you can adjust for your UART network.  These options are discussed in the following topics: 
Timing/Baud Rate, Initialization, and Error Checking.
