INTELLIGENT PRINTER SWITCH PLUS
2.1 Overview
The Intelligent Printer Switch plus (IPSP) is a high-performance buffered data
switch that provides fast turnaround for multiple PC users sharing one or two
printers. Operation is fully automatic when sharing a single printer. With two
printers, ADMENU PC software (included) or PC commands let you control
operation.
The IPSP can accept data simultaneously from all the attached computers,
buffering the overflow until your printer is ready for more. It accepts data files
from each computer on a first-come, first-served basis and recognizes each as
a single printable file. It won’t start printing another file until there’s been a
break in transmission that exceeds the timeout period. Only then will the
IPSP recognize input from the next computer.
The IPSP is available in a variety of models. Parallel models are compatible
with PCs, printers, and plotters that support IBM®PC and Centronics®parallel
interfaces. Serial models support the EIA RS-232 standard serial interface.
Table 2-1 provides a complete list of all the models. Unless otherwise noted,
the information in this manual is applicable to all the models.

3.1 Configuring Your Intelligent Printer Switch plus
Figure 3-1 below shows the rear panel of an eight-port Intelligent Printer
Switch plus (IPSP). On a six-port model, the top two connector slots on the left
would be empty. On all models, Port 1 is a dedicated printer-output port. Port
2 is a bidirectional input/output port. The remaining ports are all computer-
input ports.
Refer to Figure 3-1 as you read the configuration instructions.
Figure 3-1. Rear view of an Intelligent Printer Switch plus.
3.1.1 P ARALLEL M ODELS
Set the option switches on the underside of the IPSP to the settings required
by your system. (See Figure 3-2 on the next page.) The default settings are
suitable for most installations. Note that the option switches are read only
when the IPSP is first powered on.
Timeout
The IPSP switches between users on a timeout basis. If no data has been sent
from the current user for the timeout period, the IPSP will switch to the next
user. A timeout period of 16 seconds (the default setting) is suitable for most
systems.
Mode
If you are using fast PCs and printers with enhanced parallel ports, burst
mode may speed up your printing performance. For most systems normal
mode (the default setting) will give the best overall performance.

CHAPTER 3: Installation
Port 2 Direction
Port 2 can be used as an input from a computer or an output to a printer. In
automatic mode (the default setting), the port intelligently detects the type of
device that it is connected to and configures itself automatically. You can also
manually switch the port from input to output using the option switches.
When using data boosters or powered cables, you should set the direction
of the port manually, because automatic detection might not work. If you
experience any problems with Port 2, set the direction manually.

3.1.2 S ERIAL M ODELS
Set the option switches on the underside of the IPSP to those required by
your system. (See Figure 3-3.) The default settings are suitable for most
installations. Note that the option switches are read only when the IPSP
is first powered on. The IPSP can be set to use these types of flow control
(handshaking):
DTR/CTS (Hardware Handshake)—Uses hardware signal lines (Pins 5
and 20) to control the flow of data.
X-ON/X-OFF (Printer & Plotter Connections Only)—The flow of data is
controlled by the receiving device, which transmits X-OFF (stop data flow)
and X-ON (start data flow) characters to the IPSP. Use this setting only on
ports connected to printers and plotters.
X-ON/X-OFF (Computer Connections Only)—The flow of data is controlled
by the IPSP, which transmits X-ON (start data flow) and X-OFF (stop data
flow) characters to the computer. Use this setting only on ports connected
to computers.
NOTE
The X-ON/X-OFF setting for printer and plotter connections WILL NOT
WORK correctly for computer connections and vice versa. The X-ON and
X-OFF characters are not passed through the IPSP.
ETX/ACK—The flow of data is controlled by sending blocks of data and
waiting for an ACKnowledgement character to be received.
3.2 Selecting Ports for Your Equipment
If you’re sharing one printer, connect it to Port 1. You may use any of the
other ports to connect to computers. If you have two printers, connect the
most commonly used printer to Port 1 and the other to Port 2. By default,
all print data will automatically be routed to Port 1.
All ports have equal-priority access to the Intelligent Printer Switch plus, and
data output is handled on a first-come, first-served basis.
3.3 Connecting PCs and Printers
Turn off power to all computers and printers before connecting them to the
Intelligent Printer Switch plus.

17
CHAPTER 3: Installation
3.4 Powering On Attached Devices
You can switch on your equipment in any order; however, it is generally better to
switch on all your devices at the same time or switch on the Intelligent Printer
Switch plus last. When the IPSP is powered on, the Buffer and Activity LEDs will
flash for a few seconds while the unit performs a self-test.

INTELLIGENT PRINTER SWITCH PLUS
3.5 Enabling Your Computer Ports
3.5.1 F OR P ARALLEL M ODELS
Your PC’s parallel interfaces do not normally need to be configured.
However, for IBM PCs running DOS, PC timeouts may occur if the buffer on
the Intelligent Printer Switch plus becomes full. To prevent timeouts in case of
a full buffer, use the MODE command with the “P” parameter, like this:
>MODE LPT1:,,P
This forces your PC to retry sending the data to the IPSP instead of timing
out. Refer to your DOS manual for more information about the MODE
command.
3.5.2 F OR S ERIAL M ODELS
To enable your PC’s serial ports, set the required data rate and data format.
On IBM compatible PCs this can be done with the DOS MODE command.
You may also use the ADMODE software utility supplied with the IPSP (see
Chapter 6). The MODE command can be used together with the ADMODE
command.
The ADMODE settings will always override the MODE settings, and the
MODE command (with “P” option) can be used to prevent application
timeouts. The example shown below would set COM1 to 57,600 bps, no
parity, eight data bits, one stop bit, and no application timeout. (See
Chapter 6.)
>MODE COM1:9600,N,8,1,P
>ADMODE COM1:57600,N,8,1
On IBM PCs running DOS, you might also want to redirect all print data that
would have been sent to the parallel printer port (LPT1) to the serial port. To
do this, use the MODE command this way:
>MODE LPT1:=COM1:

19
CHAPTER 3: Installation
3.6 Using the Intelligent Printer Switch plus
Once all the preceding connections are made, your Intelligent Printer Switch plus
is ready for use. Each attached computer can commence printing as if directly
connected to a printer. By default all print data is routed to Port 1.
If you want to route data to a second printer attached to Port 2, you’ll need
to use the ADMENU software utility (see Chapter 4) or appropriate PC
commands (see Chapter 5). Once a computer has selected a new printer, all
print data from that computer will be routed to this printer until a different
printer is selected, or until the IPSP is switched off.
3.7 Front-Panel Indicators
Activity LED
Lights — When data is available or a timeout is pending. (If data has been
sent in on a port, the activity light will remain on until the port has timed
out.)
Dark — When no data is being transferred and no data is available.
Flashes — When data is being transferred.
Buffer-Status LEDs
These show the current state of the internal buffer’s memory capacity:
■
■—Buffer is more than 1⁄4full ■ —Buffer is more than 1⁄2full
■ ■ ■
■ ■ —Buffer is more than 3⁄4full ■ ■ —Buffer is completely full
If your buffer frequently fills to the 3⁄4level, you should consider ordering the
optional Memory Expansion to increase performance. The Intelligent Printer
Switch plus will continue to operate even if its buffer is full.

INTELLIGENT PRINTER SWITCH PLUS
4.1 Overview
The ADMENU printer-control software allows you to switch between printers
and to control printer functions. It’s located on the utility-software diskette
supplied with your Intelligent Printer Switch plus and is for use with IBM
compatible PCs. You can run the software as a memory-resident or
nonresident program in both DOS and Windows®environments. Installing
ADMENU as a memory-resident program allows you to “pop up” the menu
on your screen using a hotkey combination.
4.2 Installing the ADMENU Software
The ADMENU installation program (INSTALL) will automatically copy files
to your hard disk and install ADMENU as a memory-resident or nonresident
program as required. You can also install the software by adding the
ADMENU command line to your AUTOEXEC file (see Section 4.5).
The following commands refer to the floppy drive as drive “A”. If your floppy
drive has a letter designation other than “A,” substitute that letter for “A” in
these commands.
To install ADMENU:
• Insert the ADMENU disk in drive A and type:
A: <enter>
• Then (at the A: prompt) type:
INSTALL <enter>
• Follow the instructions given in the installation program.
• Reboot your PC.
