AS-i Megablocks are DIN-rail mounted passive* hubs for the AS-i

network. They connect several AS-i devices to the network trunk

cable and provide short circuit and over voltage to the segment. The

AS–i Megablock itself does not contain an AS–i chip or communicate

over the AS–i network, so it consumes no network communication

resources (bandwidth, slave addresses, etc.). They are used to

interconnect AS–i master and slave devices that do contain AS–i chips.

Megablocks minimize hand wiring and allow individual devices to be

added to and removed from the segment without disrupting network

communication. A green power LED on each unit indicates whether

DC power is present. Megablocks are available in four and eight drop

versions. Multiple Megablocks are easily wired to one another to allow

larger segments to be constructed.
