Simulink - Serial Receive - Header

Hey,

I'm reading serial data from a Interial Measurement Unit and dont know how to define a header properly. One frame is 56byte long (with 48byte of data). On the picture you can see the Block Parameters on the left and the Data on the right. The first 2 bytes (255 2) are the header, ending is 3.

I don't know the synatx to define the header, when i simply type 255 into header, i get only zeros for data.

Thanks for helping!

Try HEX. For example 'FF' for 255

Already tried that. Dont work. But i saw unter Terminator you can choose: CR('\r') for Carriage Return (ASCII). I have a start of text STX and ETX at the end, but there is no c code for it like \r.

Header Specify data that marks the beginning of your data block. The header indicates the beginning of a new data block and the simulation will disregard data that occurs before the header. The header data is not sent to the output port. Only data that occurs between the header and the terminator is sent to the output port. By default none or no header is specified.

Anything entered in the header is treated as a character. If you want to specify numbers, you need to use the corresponding ascii characters for them. For example, to specify [40 41], you can enter () in the field. Note that single quotes are also treated as characters. You can use the corresponding ascii characters for the numbers between 32 and 126.

hi,Kai,did you solve this problem? may you help me get the correct synatx of the header that corresponded ascii characters more than 127.
