Connecting Hubs Using 10BASE-2 (Coaxial)

Figure 3 Correct Hub Connections Using 10BASE-2 (Coaxial)

When using 10BASE-2 (Coaxial) cable, it is important that both ends of the segment are properly terminated with 50 Ohm terminators (end pieces).

Only use 50 Ohm 10BASE-2 (Coaxial) cables and use a ‘Y’ piece for each hub. You can use ‘T’ pieces but ‘Y’ pieces provide optimum clearance of the other ports.

Connect a 10BASE-2 ‘Y’ piece to each of your hubs. Daisy-chain each ‘Y’ piece with 10BASE-2 (Coaxial) cable to form a single segment (as shown in Figure 3). Remember to terminate the two free ends of the segment by fitting terminators (end pieces).

To disconnect a 10BASE-2 (Coaxial) cable, twist each connector counter-clockwise to unlock it, and remove it.
