EN-1611 is a hub that complies with IEEE 802.3 Ethernet standards. This hub features 16 modular RJ-45 UTP ports for UTP wiring, one RJ-45 uplink port for hub cascading, one DTE Attachment Unit Interface (AUI) port for Thick Ethernet cabling, and one BNC port for Thin Ethernet cabling. With these features, all different Ethernet cabling systems can be connected together with a wide range of configurations.

Each UTP port is equipped with a TP Link/Rx LED to indicate the network connection status (Steady - TP port is connected to an active node and receiving a valid Link Integrity plus. Flashing - data are passing through this TP port.) The power LED indicates whether is 'ON' or 'OFF'. These LEDs offer a great aid in diagnosing line troubles and indicate when data is being received or transmitted.
