10base2-Thin Ethernet

10BASE-2 - Thin Ethernet got its name because the coaxial cable it runs
on is thinner than the cable used for Thick Ethernet. 10 is for 10 Mbps
operation, Base is for baseband operation and 2 is for a maximum of 200
meters (actually, 187 meters) of cable segment length. The Network
Interface Card (NIC) performs the functions of a transceiver so that no
external transceiver is needed for workstations.

10 BASE 2 PARAMETERS AND WIRING RULES

Maximum length per segment is 185 meters or 607 feet.
Maximum of 30 stations per segment are allowed.
Maximum of 1024 stations may be attached to a 10Base2 network.
Bus topology.
NIC's come with built-in transceivers so connections are made directly to NIC via T-connector.
Typically, devices are daisy chained using T-connectors so there must be 2 cables connected to each workstation; 1 going IN; 1 coming OUT.
T-connectors must be plugged directly into NIC. There can not be any cable between T-connector and NIC.
A minimum of 0.5 meter or 1.6 feet is allowed between T-connectors.
BNC transceivers and transceiver cables must be used on NIC's that do not have built-in transceivers.
Maximum transceiver cable length is 50 meters or 165 feet.
External Transceivers must be placed at least 0.5 meters or 1.6 feet apart.
Both ends of the cable segment must be terminated with a 50 ohm terminator.
One end of the cable must be grounded. The other end must remain ungrounded.
Terminator must be attached to open jack of T-connector at both ends of the segment. Do not attach terminator directly to cable without T-connector.
Repeaters may be used to extend the signal.
Maximum of 2 repeaters may be used between devices.
