Coding using MT RS Encoder Decoder

[alexpas]

I want to implement a RS(255,239) in the attached VI. Can anyone help? I don't understand what'is wrong?

I use an MT Bit Generator (3824 bits) -->  MT Pack Bits (bits per Integer = 😎  --> MT RS Encoder (255,239 bits per symbol = 8 )

When accessing the RS Encoder I get Error -1 occured The NUmbers cant be Zero

Hi alexpas,

When running your VI, I also the following error message :

Error -21892 occurred at mod_Validate RS code prms.gvi "RS Galois primitive element must be relatively prime to the Galois field order 2^m-1 in GF(2^m)."

Modifying the Message bit count may solve your issue,

Actually the message bits are selected on purpose to be t*239 in order to meet the requirement for the MT RS encoder as it is a pack encoder. Nevertheless I've tried that but still the same errors!

Hello alexpas,

I was able to reproduce the error -1. I have done some investigation into the error and found that it is thrown by one of the VI's subVIs. I modified the mod_Configure RS attributes.gvi into to resolve this error.

Please download the attached VI, and use it to replace the <LabVIEW Comms 1.1>\Resources\vi.lib\Native\mod_Configure RS attributes.gvi.

This should resolve the error. Please see the attached VI.
