serial to parallel vs UART RX

[sarah23]

im using system generator 10.1 ....i use block serial to parallel converter that is i think equivalent to UART RX. ......... now i want to send data through hyper terminal and use those characters to run the next block....but those characters does't appear after serial to parallel conversion as a single assigned pin can represent a character e.g 'a' ....can anybody suggest me something...?

A serial to parallel converter is not equivalent to UART RX.
UART RX is more complicated since it must handle an asynchronous input signal.
Typically, the UART clock is 16 times the baud rate. A serial to parallel converter is normally clocked at the baud rate and the data must be synchronous to the clock.

You really need a UART RX if you want to use a terminal.

thanx 4 the info. , i got it serial to parallel / parallel converter operates on synchronous input output signals based on system clock.....but let say it if i make the inputs syn. to system clk then it will work isn't it ....? i can try it because i know terminal baud rate e.g 9600 bits/sec and then try changing different system clocks....will it work...? or i can also use up or down sample blocks in system generator...?
