Great Scott Gadgets - Throwing Star LAN Tap Kit

The Throwing Star LAN Tap is a passive Ethernet tap, requiring no power for operation. There are active methods of tapping Ethernet connections (e.g., a mirror port on a switch), but none can beat passive taps for portability. To the target network, the Throwing Star LAN Tap looks just like a section of cable, but the wires in the cable extend to the monitoring ports in addition to connecting one target port to the other. The monitoring ports (J3 and J4) are receive-only; they connect to the receive data lines on the monitoring station but do not connect to the station’s transmit lines. This makes it impossible for the monitoring station to accidentally transmit data packets onto the target network. The Throwing Star LAN Tap is designed to monitor 10BASET and 100BASETX networks. It is not possible for an unpowered tap to perform monitoring of 1000BASET (Gigabit Ethernet) networks, so the Throwing Star LAN Tap intentionally degrades the quality of 1000BASET target networks, forcing them
