Connect the PC's network card to the hub/switch using a standard Ethernet cable, and connect the hub/switch, again using a standard Ethernet cable, to the Bus Terminal controller.

Direct connection between PC with Ethernet card and BX9000

Ethernet connection 3:
Direct Ethernet connection between PC and BC9020, BC9050 via cross-over cable

To connect the PC directly with the BC9020 or BC9050, you have to use an Ethernet cable with a cross-over cable.

Connection via hub or switch

Ethernet connection 4:
Ethernet connection between PC and BC9120 via hub or switch

Connect the PC's network card to the hub/switch using a standard Ethernet cable, and connect the hub/switch, again using a standard Ethernet cable, to the Bus Terminal controller.

Direct connection between PC with Ethernet card and BC9120

Ethernet connection 5:
Direct Ethernet connection between PC and BC9120
