RS232 vs TTL

Hello,
In the documentation of the user manual [1] page 4 under ordering information it is mentioned that there are 2 versions.
One is RS232 the other is TTL.
Yet the scematics [2] shows that SP3232EBEY is connected so does the TTL version exist?
On mouser we find only the RS232.
How can we order TTL version of the module WIZ107SR-TTL?
