If you activate this option, the protocol displays all command that are transferred to the Device on the CAN bus that is currently selected in the Device tree. The meaning of the commands is explained in the volume The RM4200D CAN Bus Protocol of this manual.

But also without any knowledge of the protocol, especially for key functions, you can press the corresponding key. The appropriate command is then displayed in the protocol. You can then use it e.g. to manually send it or use it in a script. (see also Scripts – Controlling Special Functions with Scripts )

Figure 19: Display of the messages on the CAN bus and menu Protocol.

Use this option, if you want to monitor the UDP traffic of a certain Device only. Activate this option, and select the Device to monitor in the device tree. If there is a check mark in front of the menu entry Filter Foreign UDP Blocks, the protocol output is filtered to show the messages from the selected Device only.

Use this dialog to send CAN bus commands to the RM4200D manually.

	Warning
	Only use this function, if told so by your DHD dealer or DHD support or if you know exactly what the commands do! Wrong CAN bus commands – an these include typos in otherwise correct commands – can disrupt the operation of the RM4200D or cause it to stop working at all. If in doubt, ask first before sending CAN bus commands!

Figure 20: The dialog for sending CAN bus commands manually.

You can send CAN bus commands manually using the five input fields of the window. To do this, enter the desired command into a field or copy it from the clipboard using the key shortcut Ctrl+V. If you then click on the corresponding Send button, the command is transmitted directly to the CAN bus of the selected Device and can there be executed by the modules.

The following table contains some examples for CAN bus commands:

This command deletes the content of the protocol pane.

This command transfers the content of the protocol to the Windows editor as plain text.
