For flexible use with both the thin and thick cables, each port is equipped with a BNC and AUI connector. Switch-setting is not required to select a connector. The repeater auto-detects the active connector. The dual interfaces of each port allow reconfiguration of the connected segments. For any port, the thick cable can be removed and the thin cable connected, or vice versa, anytime without first turning off the repeater's power.
Users press the reset button instead to re-initialize the repeater.
