How can i make a binary generator like bernoully binary generator but with my own binary data?

i would like to make in simulink a binary generator with the words ('Hello World') in binary, i mean no random data like bernoully binary generator does. i tried getting he binary data usin dec2bin('Hello world') in matlab, and making an matrix with two columns, the first with time column and the sencond with the binary data i obtained (both with the same length) and then using the from workspace block in simulink. But even if i can see the signal usig an scope i notice that i just get 1 bit in the output of the fromworkspace block, but with a bernoully binary generator i can get for example an output of [256x1]. that's what i want, a binary output of [256x1] or whatever number of bits the 'hello world' words have not just 1 bit. is there any way to get it in simulink?
