Communication

HANtune supports various ways of communicating. With regards to hardware support there are three options: Ethernet, USB and CAN. Ethernet and USB/UART can only be used in combination with the XCP (universal Calibration Protocol). The CAN-bus can be used either with or without XCP functionalities. This chapter provides more information about the (combination of) these options, as well as the general communication settings in HANtune.

7.1 Communication Settings

Image 11: Communication Settings Dialog shows a screenshot of the communication settings in HANtune. It can be found under the menu item “Communication” > “Communication Settings” and in the connection dialog by clicking the button “Settings”.

In the tab “General” the general communication settings have to be set. A choice has to be made for a communication protocol.

7.2 XCP on CAN

The timeout prescaler is used to define the communication time-out. If HANtune doesn’t receive any messages anymore, by default it cancels the connection after 2*t_prescaler. Please note that this is a temporary solution. It is planned that in a future version of HANtune the behavior of the timeout prescaler will be depending on the expected delay time of incoming messages. The other tabs contain hardware-specific settings for CAN, Ethernet and USB, respectively.
