Connecting to Hubs
The following table lists the types and the maximum number of hub
connections depending on the configuration switch setting:
Configuration Types of hubs Connections
10M mode 10BASE-T hubs up to 8
100M mode 100BASE-TX Class II hub one
100M mode Dual-speed Class II hub one
AUTO mode 10BASE-T hubs up to 8
AUTO mode 100BASE-TX Class II hub one
AUTO mode Dual-speed Class II hub one
The cables used and maximum distance allowed for a hub connection are:
Hub Port connected Cable used Distance
10BASE-T hub port Cat. 3,4,5 100 meters
100BASE-TX hub port Cat. 5 5 meters
Auto-sensing hub port Cat. 5 5 meters
Connecting to 10M Ethernet Hubs
KF-8D can support up to eight 10M Ethernet hub connections.
The Ethernet connection rules should be followed as follows:
1. Between any two end-nodes in a collision domain, there may be
up to five cable segments and four intermediate repeaters (hubs
or other repeaters).
2. If a path between two end-nodes contains five cable segments,
no more than three populated segment can exist in the path.
The following figure illustrates a connection example:
