Hi Toony

I'm assuming that you know what a controller is, but let me know if you don't.

Have you been able to access the 218 configuration program yet? There is an area where you can change the comms configuraiton. This area allows you to make the 218 a controller. I was suggesting that you make this configuration change. Then store the setting and then restart the 218 by removing the power and reinserting.

Cheers
Tom
