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:

1 2 ... 10 11 12 13 14 15 16 17
