need 6 channel controller w/rs232 radio modem interface

Hi. I'm new to the robotics field and I am trying to design a robot. I want to control the bot with a radio modem. I have located IFI's Isaac controller with their raadio modem and it would be exactly what I need except the range is limited to about 300 ft and you must use their components together. I can find RS 232 radio modems with ranges to 7 miles or better but no 7 channel controllers that will interface with them. Can anyone help? :)

See www.maxstream.net for the RF modem. If you find one that looks like it has the range, we can then look into the 6ch problem. It will take some creativity but should not be impossible.

Hi Cosma -

I had found the maxstream site earlier and their latest 1 watt 900 Mhz Spread spectrum modem is overkill but I like their power output and small form. I called a dealer for Maxstream and so far, no one has it in stock. Maxstream also has a 1/2 watt OEM modem rated for 7 miles that will work. Data format (rs232. 422, 485 etc) is dip switch selectable. The 6 channel part is a trick though isn't it? :confused:
