Planning a Network Installation
Ground only one of the two terminators. If your termina-
tor doesn’t have a grounding strap, attach a length of
wire to it. Then attach the other end of the wire to the
center screw on an electrical outlet cover plate.
The coaxial cable BNC connector must attach directly to
a T-connector that attaches directly to the device.
Figure 1-4 shows an example. (Drop cables do NOT
meet IEEE specifications.)

The maximum number of devices per segment is 30
(repeaters count as one device).
The minimum distance between devices is 0.5 meters
(1.6 feet).
The maximum segment length from hub to transceiver,
including the thin coaxial cable, is 185 meters (607
feet).
Use approved building wiring standards or consult a pro-
fessional.
If the cable in your building does not meet the criteria specified above, or if
workstations are needed where no cable exists, you need to install new
cable. The above list is a brief overview, but this cable should conform to the
IEEE 802.3 Type 10BASE-2 specification.
Decide Where to Put the BNC Hub/6
You need to place the BNC Hub/6 in a location so that the distance of wire
between the BNC Hub/6 and any potential workstation is no greater than
185 meters (607 feet).
