Hi,

Can someone clarify the Write address command.

If i change the address of a module by software it issues the following command :

0F F9 02 07 6A 22 00 00 20 00 00 53 04

0F = Start of Frame
F9 = Firmware
02 = Acual address
07 = # of bytes
6A = Wrtie Address
22 = ??
00 = ??
00 = ??
20 = New Address
00 = ??
00 = ??
53 = Checksum
04 = End of Frame

Can someone fill in the blanks ?

Regards,
Jeroen.

I ask for help if there is to support the ability to send command to activate relay from an html page: command type 0ff8000400010000f404 to a listening server which in turn sends the command to the serial port connected to VELBUS? thanks paolo
