OVERVIEW
The eight-port active hubs, AN-808S and AN-808T, are low profile connecting device for
ARCNET network. AN-808S is designed for ARCNET network using RG-62 coaxial cable while
AN-808T is for network using twisted pair wire. With the ability of conditioning,
boosting, and relaying network signals, these hubs are used to attain maximum allowable
connection distance and to offer flexibility in the physical connection scheme.
AN-808S and AN-808T have eight ports for the connection to other ARCNET network components,
such as network adapters, active hubs, passive hubs, and repeaters. Nine LEDs in the front
panel indicate the power and eight ports' working status, thus providing a significant
aid for network diagnostic. The power LED lights when power is ON. A port LED is on
either data is being transmitted over the network or the token is being passed from
node to node. LED is OFF when the port detects no signals. No signal is detected by the
port when the cable is not connected, the cable is broken, or ARCNET adapter is not
installed on the workstation. LED blinks when the network is under reconfiguration, i.e.
a workstation joins or exists the network

AN-808S This active hub is a low
profile, 8-port hub designed to connect to multiple workstations and
additional hubs on a coax network using point-to-point star topology. It also
connects multiple ARCNET nodes on a single bus cable to the network. No
termination is required on open ends of the hub.
