Hey No problem scanning or entering codes. Is this right that when you scan the network live for the fist time all the units still start with the unit address 255. how does it work, i thought when you scanned the network it would reconise the serial numbers straight away any give it the correct unit address. Or is the only way to unravel, then check serial numbers, then download to network from database, the open each unit separtly live on the network and save like in version 2. thanks doing a great job, ben
