ATEN AS-248T, AS-248R User Manual

Code consists of a <HEADER>, a <CODE> and a <TAILER>:

Where,

<HEADER> is &+&C ie, ASCII Codes

26H 2BH 26H 43H

<CODE> is an ASCII code.

<TAILER> is recognized by one of the following 4

combinations:

<CR>

<LF>

And <CR> is ASCII 0DH

<LF> is ASCII 0AH

* Above defaults are set by AS-248T when reset.

* ’P1-P8 Auto’ means AS-248T would automatically send

files to the ready printer of the lowest number available.

For example, send following data to AS-248T:

&+&C2 <CR><LF>, select “P2".

&+&C<<CR><LF>, select 5 sec Timeout.

& +&C: <CR><LF>, select FormFeed disabled.

THE EA-100 BRIEF DESCRIPTION

EA-100 is an optional system accessory for AS-248T users. It

provides an easily accessible switch for printer selection that

eliminates the use of software.

Function Overview

EA-100’s functions include auto/manual printer selection,

FormFeed enable/disable and Timeout selections.

Connection

Ear-Phone Plug : to AS-248T’s rear ear-phone jack.

Power Consumption: 0.5mA (max)

DIP Switches and the Dial

DIP switch can be changed anytime and the functions are:

There are 9 positions for the rotating Dial on the EA-100. Set the

Dial to ’1’...’8’ selecting printer number 1...8. Set the Dial to ’A’

selecting all printers in Automatic mode.

The Dial is used to select the printer number, and is effective after

Timeout and before sending a file to AS-248T while the PC is

sending files to AS-248T, the Dial is ineffective.

THE FLASH/NET AND AS SERIES UNITS

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

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

• Be connected to a running computer.

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

line.

• 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:

THE AS-248R BRIEF DESCRIPTION

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.

Connector

Power Jack : +9V DC, 200mA (option)

Phone Jack : FLASH/NET bus connector

C-36 Connector (male): to Centronics printer

Power Consumption : 2mA (max)

DIP SW Setting

DIP Switches on AS-248Rs must be selected before connecting

AS-248Rs to printers. One and only one of the AS-248Rs must

be set to ’P1’ for the network to function and no two AS-248Rs

can be set to the same DIP switch number (see table below).

x: Can be set to either on or off.

Connect to FLASH/NET

1. Turn off all printers and computers.

2. Set up AS-248Rs’ DIP Switches.

3. Connect AS-248Ts to computer’s, Centronics ports .

4. Connect AS-248Rs to Centronics printers.

5. Link all AS-248Ts and AS-248Rs by 4-wire telephone lines.

6. Connect optional EA-100s to AS-248Ts’ rear earphone jack.

7. Turn on computers and printers.

Special Notices

• Once DIP switches on the AS-248R are changed, AS-248R

must be isolated from all connections in order to update the

change.

• Do not re-wire phone lines while printer is printing.

• Do not turn printer on or off while printer is printing.

• While printing a file, changing the Dial on EA-100 h

effect.

• If more than 50% of the printers and PCs are off, or th

e to

phone lines are longer than 500ft, or the envirom

electrically noisy, please add a power adapter to ’P1’ o

r m

adapters to AS-248Rs.

THE AS-248T BRIEF DESCRIPTION

This product is connected to PC’s LPT port for FLASH/N

least 24 AS-248Ts can be placed on the network.

Function Overview

AS-248T gets data from EX/NET controller th

FLASH/NET’s AS-248R for further process.

Connection

Phone Jack : FLASH/NET bus connector

Earphone Jack (Rear) : EA-100 connector

DB-25 Connector (male): To PC’s Centronics O/P port

Power Consumption : 2mA (max)

Connect to FLASH/NET

1. Before plugging the AS-248T to the FLASH/NET, ma

none of the AS-248T device is sending data to FLASH

2. Plug AS-248T to PC’s Centronics O/P port.

3. Connect AS-248T to FLASH/NET via phone wire.

4. Optional EA-100 can be plugged to AS-248T at any tim
