The protocols running under K-LINE require very precise byte timing. Since Windows is not a real time operational system these times are not always respected and the connection to some devices is unsuitable or it is impossible to connect to them. In such cases you can try and change some of the timing parameters from the “Advanced” button. The timing parameters have the following meanings:

• Wake up echo delay - time after slow initialization between receiving “55 xx yy” and sending the inverted value of “yy”(according to the K-LINE wake up procedure).

• Communication echo delay – time between reception of a byte under KWP1281 and sending it back to the device in an inverted form.

• Inter byte time – time between sending two bytes under KWP2000.

• Time between messages – time delay between reception of a response from a device and sending a new request to it.
