Wireless RF cable transceiver modules?

Hi,

I'm trying to setup a remote wireless link between two Arduino Mega boards. On the remote side I need to sample 2 analog inputs, and control 4 digital outputs, and I need the control turnaround time to be under 20mS. Since I'm new to RF I'm looking for a plug and play solution, that's why I've been looking into wireless cable replacement solutions.

So far I have found DataBridge modules from Starman Electric (www.starmanelectric.com), and AirCable modules (aircable.net). Is anyone familiar with these modules?

Thanks,

Not familiar with those modules - new to me. Sound interesting, though. What kind of range are you looking for? If under 200 meters, those are both overkill. Plus, since you are only needing one-way communications (at least, that’s how I am reading your post), a 2-way solution is just throwing money away (unless you have a future need for it). Would a simpler 433 or 900 MHz serial wireless module set work instead (< 200m distance, line-of-sight, 9600 or 4800 bps)? Or how about the Parallax transceivers?

Thanks for the reply. I need two-way communication since I will be sampling the two analog inputs on the remote end, send the data to a computer (which is running some other software), and then send signals back the to the remote end and control 4 digital outputs.

I would consider a 433 or 900 mhz system, but since I'm planning on going commercial in the future I need something that is FCC approved, as well as within the latency requirements. Range will be about 500m outdoor. From what I am reading, 433mhz would not be certified.

In the meantime I ordered two of the DataBridge modules. I guess we'll see how it turns out. I'll let you know.

Thanks,
