it looks like a "product brief" which gives no hint as to how you're intended to use this product. Yes, that's what I thought. Unfortunately, this does also tend to be the case with such cheap products: I said:
The reason some of these RF modules are so cheap is that they are very, very simple...
There is no such thing as a free lunch - the modules are cheap becuase they leave it up to you to provide the appropriate coding, sync, error-detection, error-correction, etc, etc... http://www.8052.com/forum/read.phtml?id=137311 And they don't provide much help in terms of proper datasheets, support, application notes, etc, etc... :-( If you want modules that will simply plug-in as a direct cable replacement, they will obviously be more expensive And, if you want good, clear documentation and support - you have to pay for that, too!

You can't work with the little data that their web-published sheets provide. You need more information than that. Have you got any additional information? There is a contact link on their site - have you tried it? Or your distributor? There are links to some other sites that might be more helpful in this thread: http://www.keil.com/forum/docs/thread8256.asp Take a look at: http://instruct1.cit.cornell.edu/courses/e...4/website/ and, of course, your favourite internet search engine...! |
