network by means of 4-wire phone lines. With AS-248Ts con-

necting to PCs and AS-248Rs connecting to printers in a Bus, Star

or Tree topology, this advanced power-free network eliminates

multiple auto switches and tangled cables. Simple installation and

easy of use makes this network suitable for all user levels.

AS-248R, AS-248T and EA-100 feature 1200ft. of maximum

network length, 22k bytes/sec maximum data throughput and

simultaneous printing.

At least 24 PCs can share 8 Centronics printers with the AS-248

• Be connected to a running computer.

AS-248T and AS-248R gain power as follows:

• Be linked to a running AS-248 network by 4-wire telephone

line.

THE AS-248R BRIEF DESCRIPTION

• Be connected to a power adapter.

Both the AS-248T and AS-248R reset themselves if all power

sources are disconnected

FLASH/NET uses RJ-11 phone line for connection, all phone

lines must be wired as:

AS-248R is connected to printer’s Centronics input port for

FLASH/NET, up to 8 AS-248Rs can be connected to the network.

Function Overview

AS-248R receives data from FLASH/NET and sends it to the

connected printer.
