AUI Port
The AUI port on the Model SW502 switch allows the 10 Mbps port to be connected to an external
transceiver for network extension. Inter-repeater fiber transceivers for 10 BASE-F or FOIRL are
examples of external transceivers. For AUI connector pin assignments, refer to Appendix B,
“Connector Pin Assignments.” For cabling specifications, refer to Appendix C, “Cabling
Specifications.”
BNC Port
The BNC connector, similar to the AUI and RJ-45 ports on the Model SW502 switch, provides
10 Mbps access for end-node or daisy-chain connections. For additional information about the BNC
connector, the BNC T-connector, and the 50
Ω
BNC terminator that are used to connect other devices
through this port, refer to Appendix B, “Connector Pin Assignments,” and Chapter 3, “Installation.”
For cabling specifications, refer to Appendix C, “Cabling Specifications.”
Half/Full Duplex Switches
The communication mode can be set to either half-duplex or full-duplex operation. One Half/Full
duplex switch is assigned to each port on the Model SW502 and Model SW507 switches.
