Does anybody have any RF Module suggestions?

Steel

I have a SX that I need to talk to about 200' away indoors.

I have to send it 128 bytes every 1mS.

I am currently sending data at 900k.

Has anybody worked with any reliable radio chipsets at this range with this data rate?

Please help.· I am lost on the internets.

Have a look at xBee-Pro: www.selmaware.com/appbee/home.htm.

SelmaWare has a variety of adapters and SparkFun has a "breakout board" as well.

I've used the shorter range xBee between a Mac and both a Propeller and a Stamp.
Once you configure it, it powers up as a wireless serial channel although there are
other modes you can use. Since it uses a packet network protocol, all communication
is error checked internally.

I just re-looked at your data rate requirement. The xBee isn't quite fast enough.
How about using WiFi and Telnet?

Here's one vendor: www.digi.com/products/embeddedsolutions/digiconnectwime.jsp

You might be able to use a directional gain antenna to improve the range and they're more
readily available as a mass market product than some special purpose system.
