How many HI 3030's can be linked together equating to how many scale channels?

How many HI 3030's can be connected together in the Hardy "Control-Link" Ethernet network and how many scale channels does this equate to?

Up to 17 HI 3030 Weight Controllers may be linked in the "Hardy Control-Link" Ethernet network. This would be done by entering into each unit, the IP addresses of the other 16 units on the Hardy Control-Link page. 

Each HI 3030 may have up to 4 scale channels with the possibility of 68 scale channels on the network. Caution should be used with trying to link together this many scales, as communications may be slower than normal over the network and could have an impact on some other network traffic if this is not an isolated network.
