8 GETTING TO KNOW THE M208: Overview of the Hub Architecture
Printer Support
The M208 is compatible with PC’s, UNIX systems, Macintosh computers, minis, and
mainframes as long as at least one of the following is present:
TCP/IP
• an LPR client to interact with our Line Printer Daemon on the unit,
• an RSH client (i.e. rsh, remsh, rcmd) to interact with our RSH Daemon,
• the ability to print directly to a TCP port number on our unit; we have a TCP port
number mapped to each I/O port on the unit by default (i.e. com1 is 4000),
Other
• NetWare support,
• AppleTalk over EtherTalk support,
• NetBIOS over TCP/IP support,
For a listing of the printing standards supported, please see Standards Supported on
page 193.
Overview of the Hub Architecture
The M208 includes a fully managable eight port Ethernet hub. Hubs are stable net-
work devices that perform signal regeneration (including amplification, symmetry,
and retiming), packet forwarding, and routing. When a hub is presented with a data
signal, it automatically regenerates and transmits the data signal to all the other hub
ports without any modification to the signal.
The M208 has a total of nine Ethernet ports, eight 10Base-T (RJ45) and one AUI port.
Any port on the M208 can serve as the network connection for the unit.
Very little configuration is required for the hub as it becomes fully operational as soon
the the unit is powered up. To install the hub, simply attach it to the network and con-
nect other Data Terminal Devices (DTEs) to it.
For more information on hub installation and configuration please see USING THE
HUB on page 19.
