Ascii Decode Block simulink

I must say i can't speak english properly, so, sorry for my bad english hahaha. Well, i got a trouble with ascii decode block in simulink, i'm working with a serial receive, an analog value between 0 to 255, i conect the serial receive block to ascii decode and i see the value with a display. The issue is display show a number between 0 to 9, for example, if i got a 255 in the serial port, display just show me the last number (5). i think the problem is the format string of ascii decode, however, if i try to write "%d,%d" , i get a "simulation diagnostics, RS232/Rec: receive data error".

I tested the serial comunication with hyperterminal, virtual terminal (proteus), and all it's okey... I got a headache with ascii decode block haha, please i need help about this.

set the datasize to [1 3] means that 3 character before terminator will be saved. If you set the datasize [1 1] means that only one character will be saved. Thats why when you received string "255" only "5" will be displayed. I already figured it out.

I use this protokol to send the data ("%3d %3d\r") and setting the receive serial block like this: terminator --> CR/LF data size -->[1 7]

setting for ascii decode: format string --> %3d %3d\r (dont forget with spacetab) number of variables 2

and I use this protokol to send my data --> %3d %3d\r (dont forget space tab)

hope this will help you
