About EtherTalk Phase 1 and Phase 2

 

If you have installed EtherTalk Phase 1 and Phase 2, selecting 
Phase 1 may make Phase 2 network resources invisible and 
unavailable.  The reverse is true for Phase 2.  To see if this is 
the case, switch from one EtherTalk icon to the other. 

Phase 1 networks are limited to 254 nodes and one zone. In a 
Phase 2 network, up to 16 million nodes can be addressed on an 
Ethernet network.  Phase 2 networks support multiple zones 
sharing the same physical cable. A great majority of network 
installations now use only Phase 2.
