Som e UART standards such as Keyword 2000 and ISO 9141 require you to initialize an ECU before attem pting to send m essages to it. Usually this initialization involves signaling on either or both of the K and L line. You can

select the initialization from the Init table section of the ISO 9141/KeyWord 2000/K-Line section of the hardware Ex plorer (figure 1)

You can cause a initialization to occur on the network by click ing the Init colum n in Vehicle Spy or setting the init flag in the status bit-field in the m essage you send via the DLL. The m essage can have no data bytes (for five

baud initialization for ex am ple).

neoVI supports the standard initializations lik e Fast Init and Five Baud. Also, neoVI also offers a custom initialization because there has been a variety of initialization im plem entations.

For custom initializations you can have a 16 step waveform . This is defined in the custom initialization table in hardware ex plorer. Each step can last up to 32.767 seconds and can control both the K and the L line.
