Dear Islam Fouad Elkholy,

A-Link ports of NetBotz devices are absolutely equal and identical. Therefore, all three connection methods are correct and can be applied:

Term->ALnk|NetBotz|ALnk<---->ALnk|TH1|ALnk<---->ALnk|TH2|ALnk<-Term

Term->ALnk|TH2|ALnk<---->ALnk|NetBotz|ALnk<---->ALnk|TH1|ALnk<-Term

Term->ALnk|TH2|ALnk<---->ALnk|TH1|ALnk<---->ALnk|NetBotz|ALnk<-Term

The basic rule of the A-Link bus, as for similar serial data buses, is the use of terminators (wave impedance balancers of the communication line) at both ends of the communication line.

With respect.
