Wireless program

I think it may be a bit harder to have the 200 pause at the recev end. I'll describe my whole project to you:
I'm building a drink despencer, similar to the ones seen behind KFC and the like. I have 2 picaxes, one as sort of like a "remote control", the other on the despencer it's self. The Remote has an LCD screen which displays a temp value from the despencer sent via wireless. The remote also has 4 switches which, when "ON" send a signal via wireless to a certain relay which dispences some water or what ever.
So basicly, my code at the moment is when ever say SWITCH 1 is High, send signal to wireless relay, looping back every 200ms. When its low, return to the "Main menu".
Another quick question, is it possible, since i have a receiver AND transmitter on EACH board, have them sending data at the same time? Ie, one will send "turn relay on" and the other will send the data from the temp sensor to the LCD.
Any additional info from anyone would be great.
Cheers

Dippy, are you having an OFF day ?
You missed the "water or what ever."

Also, if they are on the same frequency / channel, two transmitters cannot transmit at the same time.
As noted by Dippy, if the dispenser misses the "stop" command you'll soon have a flooded floor. In this type of application it is far better to have the transmitter work as an activator, just like a button push which causes a sequence to unfold and stop of its own accord, under its own control - even if the 'button' ends up jammed on.
Sod's Law - Whatever can go wrong will go wrong. And at the most inopportune moment and despite hours of testing which shows it will never ever happen.
With that in mind, you may also want to build in some protection to prevent the dispenser being triggered by someone locking their car with a key fob nearby or an emergency service digital radio transmission interfering with the system.
