Hi moonmonkey,
Presuming you are referring to the document Patd posted, it looks like you could use the TCP/IP data source, with 'configuration in hex' selected, and set values as simple hex string without the 0x prefix, so if I have a write command on a TCP/IP point like:
0101
Then every time I set any value whatsoever to that point, I'll get out the binary...
0000000100000001
it would toggle that output, and it's value regex will be given a chance to parse incoming data on the socket. Here's a point that should do something (you'll need to set the host and port) but it is not a realistic expectation for me to get too deep into your documentation for the sake of answering your questions for free.

Some people will, instead of writing a point for each output command, have a point with the write command %VALUE% only, such that they can have more control over the communication by passing values out through a scripting data source script setting the command point, and then focusing the definition of points on taking data in.
