incorporates an external power supply connection, one coaxial
connector, a Link Status LED and a Power LED. (The Centronics
connector on the front of the Print Server plugs directly into a standard
parallel printer port.)
• Software upgrades performed by network via FLASH EPROM.
2.2 Description
The Patton Model 2126 PeNetTM Print Server supports multi-
protocol printing in both Novell and TCP/IP LANs, and is fully compliant
to the ANSI/IEEE 802.2 and 802.3 Standards. Able to recognize up to
250 servers, the Model 2126 can simultaneously logon to ten of them. If
the network moves and changes frequently, the Model 2126 can also
be configured to continuously scan and log on to new servers.

In case of power loss, the Model 2126 can restore connection to
servers that are downed. It also supports all the Novell printing and
print server features. The PeNetTM supports print speeds greater than
60,000 bytes per second. Configuration is accomplished using a Novell
compatible utility. (For TCP/IP environments, configuration is
accomplished via Telnet sessions.) FLASH EPROM allows upgrades to
be done efficiently through the network.

Follow the steps below to connect the Print Server to the printer and
network (the order is not critical):
STOP! If you are connecting the Print Server to a TCP/IP
network that is not Novell based, go immediately to Section 5.0
TCP/IP Operation. If you are connecting the Print Server to a
Novell network, or to a Novell network running TCP/IP, continue
on to Sections 3.4 and 4.0.
1. Connect the required network cable (10Base2) to the modular
connector on the Print Server (The Link Staus LED will not glow
until power has been applied to the Print Server.)
3.3 Installing UCONNECT on a Workstation
2. Plug the power supply adapter into the jack on the rear of the Print
Server and then into a (surge protected) AC wall outlet.
UCONNECT is the configuration utility that is supplied with the
Print Server. UCONNECT allows the Print Server to be installed on a
Novell network, and will run on any Novell compatible workstation.
(Note: Both Novell and TCP/IP parameters can be configured using
UCONNECT. However, you cannot run a TCP/IP session in
UCONNECT. See Section 5.0 for more information.)
Note:
Some printers are able to supply 5 V DC (TTL Spec.) on
pin 18 of the Centronics connector. If your printer is one
of these, you may not need the AC power adapter.
When sufficient power is applied to the Print Server (external or
interface power), the Power LED will glow and the Print Server will
boot up. The Link Status LED should also glow, since you have
presumably accomplished Step 1 already.
UCONNECT is supplied on a PC-DOS diskette. For your
convenience, we recommend that you copy the utility (file name
UCONNECT.EXE) to your workstation hard drive. The transaction
might look something like this:
3. Immediately after performing steps 1 & 2, connect the Print Server
directly to the parallel port of the printer and turn the printer ON (if it
is not already ON)
MD C:\UCONNECT
(insert diskette into drive A)
COPY A:\*.* C:\UCONNECT
Approximately 15 - 30 seconds after booting up, the Print Server will
spool a status page to the Centronics port. If you have connected
the Print Server to the printer and turned the printer ON within that
time frame, the status page should print. The status page shows
the unit’s current operating parameters and proves that a good
printer connection exists.
Once the utility program has been copied to the hard drive, type
UCONNECT at the DOS prompt and press [ENTER] to execute the
utility.
What if a status page does not print after 15 - 30 seconds?
a) If you did not connect to (and turn ON) the printer right away, it is
possible that the Print Server spooled a status page before the
printer could respond. Disconnect and reconnect power to the Print
Server. This will reboot the print server and spool another status
page.
(Continued)
b) Is your printer set up for Postscript? If so, this will interfere with
the default set-up of the Print Server. The status page may be
garbled or may not print at all. See Section 4.8 on General
Troubleshooting.
c) If your printer has a large buffer, the printing of the status page
may depend on the timeout setting within your printer. It may take a
few minutes for a large print buffer to timeout and print.

3.4 Using PCONSOLE
PCONSOLE is a Novell supplied utility for setting up Print Queues
and Print Servers. Before it is possible to print using the Print Server
unit, it will be necessary to use PCONSOLE to inform Novell of the
presence of a new Print Server and to create/attach print queues to this
Print Server. You will require Supervisor privileges to create a new
Print Server and Queue.

Password screen. Key in the password “PATTON” and press [ENTER]
to move to the Available Configuration Options screen.
Each of the options on the General Configuration Parameters screen
can be edited using the arrow and [esc] keys to scroll and select.
1) The Configuration Password may be altered to suit your needs.
9) The Available Configuration Options screen lets you select several
pathways of configuration depending upon the operating system your
network is using. Section 4.3 will give you an overview of the
configuration options so that you can custom-tailor the Print Server to
your own requirements.
2) The Upgrade Password may be altered, but we recommend that
you leave this password unchanged.
3) You must change the Postscript Printer field to YES if your
printer uses Postscript. Otherwise, the printer will not output
correctly.
4) The Power up Status Page field may be changed to NO if you do
not want a status page to appear upon power up of the Print Server.

4.2.2 Novell Configuration
2) Once you have selected a print server to configure, you will receive
the Advanced Novell Configuration screen, where you can point the
print server to particular file servers and print queues.
The second option on the Available Configuration Options screen
lets you enter information to configure the Print Server to work in a
standard Novell environment. Any of these fields may be edited.
Warning! Contact your Novell Administrator if you are unfamiliar
with Novell setup procedures.
4.2.4 TCP/IP Configuration
The fourth option on the Available Configuration Options screen lets
you configure the Print Server to work in a Novell network running
TCP/IP. Remember: You cannot run a Unix session using
UCONNECT. See Section 5.0 for TCP/IP operation.
4.2.3 Advanced Novell Configuration
The third option on the Available Configuration Options screen is
“Advanced Novell”. This is UCONNECT’s alternative to the
PCONSOLE print queue utility. Advanced Novell lets you point a
particular print server to specific file servers and print queues. This is
done in two steps:
4.2.5 Personal Netware Configuration
1) When you select the Advanced Novell option, you will be prompted to
supply a print server to configure. Use the arrow and [esc] keys to
scroll and select the print server you wish to configure. Then press
[ENTER].

4.2.6 Reset to Factory Defaults
2) After you have sent your configuration changes to the print server
and have seen a timeout at the bottom of your screen, you will then see
the Reboot screen. Selecting “Yes” on the Reboot screen immediately
reboots the print server and takes you to the DOS prompt. The
configuration changes you have entered will now be in effect. Selecting
“No” on the Reboot screen takes you immediately to the UCONNECT
Main Menu. Your configuration changes will then not take effect until
the next time the Print Server is rebooted.
The sixth option on the Available Configuration Options screen
resets the Print Server to all Factory Defaults. If you select “Yes” on the
Reset Available Configuration Options screen, UCONNECT will reset
the Print Server and return you to the . If you select “no” on the Reset
screen, UCONNECT will return you immediately to the Available
Configuration Options screen.

No
Warning! If you select “Yes” you will lose all changes you have
made in the configuration process.
Warning! Do NOT remove power while the timeout message is
displayed! Only after the timeout message disappears is it safe to
remove power from the Print Server.
4.2.7 Exit
4.3 Testing within Novell using UCONNECT
The seventh option on the Available Configuration Options screen
exits to the Main Menu. However, you will exit directly to the Main
Menu only if you have made no changes to the configuration of the unit.
If you have made changes, you will be sent into the following sequence:
The UCONNECT utility may be used to test the Print Server in a
Novell environment. To access the Available Test Options screen,
perform the operation described in Section 4.2, choosing Test from the
Main Menu instead of Configure. When the screen appears, pressing
[ENTER] will cause the Print Server to print a status page, thereby
testing the setup. Choosing “Exit” will take you back to the DOS
prompt.
1) If you select Exit and you have made configuration changes, you will
next see the Send Changes screen. If you select “No” on this screen,
you will go immediately to the UCONNECT Main Menu and your
changes will not be saved. If you select “Yes”, you will receive a
timeout at the bottom of your screen while UCONNECT sends your
configuration changes to the Print Server. (Note: the changes you
entered will not take effect until the Print Server is rebooted.)

4.4 Printing within Novell
It will be of great benefit to users who are not familiar with the Novell
printing environment to obtain the Novell flip-guide entitled “Novell
Quick Access Guide” before continuing with this section. Read the
chapter entitled “PRINTING” to gain a clearer understanding of the
Novell printing system. More information is available from Novell’s
Concepts and Print Server manuals.
The PeNetTM Print Server interface fully supports all common Novell
print commands including CAPTURE, NPRINT and PCONSOLE.
4.6 Troubleshooting within Novell
This section describes the options available for diagnosing possible
problems that may occur with the PeNetTM Print Server unit.
e.g. NPRINT testfile.doc PS=PESERV Queue=TEST
The Novell set up utility, UCONNECT can be used to force print a
Status Page to the connected printer. Select Force Status Page from
the main menus within UCONNECT.
This command prints a document called ‘testfile.doc’ to the print
queue called TEST which is serviced by a Print Server called PESERV.
General
4.5 Upgrading within Novell
No Power LED
The PeNetTM Print Server is equipped with 128k Bytes of FLASH
EPROM which is used to store the operating code and also the units
configuration data. If it is necessary to upgrade the units operating
system (for example if support for new protocols is added) this may be
easily achieved by transmitting the new operating system to the unit
over the network. Once transmission is complete, this new code will be
permanently stored in the units FLASH memory.
1) Check that external power supply adapter is correct type and is
functioning correctly.
2) Ensure DC connector to the Print Server is seated correctly.
3) If you are relying only upon interface power on pin 18 of the
Centronics interface, be sure the output is 5 V DC (TTL Spec.).
Upgrading under Novell is achieved by selecting the UPGRADE
option from the UCONNECT main menu. Ensure that the units new
operating system (supplied on a single 3.5 inch diskette containing a
single file called IMAGEnnn.BIN ) has been copied to the same
directory that contains UCONNECT.EXE.
Status Page Not Printed
1) The status page prints only within 30 seconds of power-up or when
forced by software (see Test Section 4.3)
Enter the NIC and Network address of the unit to be upgraded and
then enter the UPGRADE PASSWORD when prompted (rather than the
CONFIGURATION PASSWORD with does not permit FLASH

General Configuration Section 4.2.1)
upgrades). Once communication to the unit in question has been
achieved, a window will appear on the screen displaying the progress of
the file transfer from UCONNECT to the Print Server (see following
page). Once this window disappears, the FLASH upgrade is complete.
3) The Postscript printer option may be set incorrectly for your printer
(see General Configuration Section 4.2.1)
4) Your printer may have a large internal buffer, in which case the
status page may have spooled to your printer but is waiting for a
timeout or command in order to print. (Check your Printer manual.)

5.0 TCP/IP OPERATION
Novell Specific
This section tells how to use the Print Server with a TCP/IP
network. Functions described include locating the Print Server on the
network, configuration, initialization, testing, printing, and FLASH
EPROM upgrading.
UCONNECT Can’t Communicate with Print Server
1) Check the correct Network Number and NIC Address have been
entered
5.1 Locating the Print Server on the TCP/IP Network
2) Ensure PeNetTM Print Server is functioning correctly (check the
power LED and status page production)
When used in the TCP/IP environment, the Print Server has one
assigned Internet Address and one printer port.
5.1.1 Assigning the Internet Address
Status Page Shows No Novell Server or Queue Details
If it is not possible to use the UCONNECT utility to configure the
units Internet Address, then the following method should be followed:
1) If Server shows, but no Queue details, then no Print Queues have
been assigned (See PCONSOLE Section 3.4 or consult your Novell
Administrator)
1. Create an entry in the ARP table using the Unix command :
arp -S [ether] IPaddress NICaddress where...
IPaddress is the required Internet Address
2) See section on “PeNetTM Print Server Unable To Login” (below)
Print Server Is Unable To LOGIN To Novell Servers
NICaddress is the units NIC address
1) Check that ‘Allow Unencrypted Passwords’ has been set to ON
2. Use PING to send this new IP address to the NIC address of the
Print Server:
2) Ensure that the units Name and Password are as allocated in
PCONSOLE
PING xx.xx.xx.xx where xx.xx.xx.xx is the IP address above
3) Check that there is a connection available for PeNetTM Print Server
(use Monitor on the Server Console)
NOTE: This method will only work if the units Internet Address is
currently set to 0.0.0.0 and PING will only affect the unit with
the NIC address entered in the ARP table.
4) If Selective Login is enabled, ensure correct File Server name(s)
have been entered
Some versions of Unix will require the ‘ether’ command to be
entered as shown
5) Check that Novell Mode is not disabled
(continued)
21
22
5.1.2 Using PING to Verify Network Communications
5.2.1 Telnet Configuration Commands
PING is the standard method used on TCP/IP networks to verify that
communication is possible to and from a given Internet address
(NOTE: not all TPC/IP networks have the PING utility. Its use with the
Print Server is optional). The Print Server will correctly respond to
PING requests and hence a typical method of quickly establishing if
communications are possible with the Print Server would be:
The following commands may be entered from the command
prompt:
GENERAL
NOVELL
Displays the current General parameters
Displays the current Novell parameters
Hint: Deleting the Novell login name will turn off Novell server
search and speed up TCP/IP operations. This step is highly
recommended.
PING xx.xx.xx.xx where xx.xx.xx.xx. is the unit’s Internet address
PING will then report to the operator if communication was
achieved. If problems exist communicating with the Print Server,
carefully check that the Internet Address allocated to the unit is a valid
address for the network in question. Consult the network supervisor if
problems persist with PING.
TCPIP
Displays the current TCP/IP parameters
PERSONAL
Displays the current Personal Novell
parameters
HELP

5.2 Configuration within TCP/IP
SET [parameter] = [value] Sets parameter to given value
Once the unit’s Internet Address has been set correctly and PING
has proven that network communications are possible to the unit, now is
the time to use Telnet to further configure the unit if required. Here is a
typical transaction used to connect to the Print Server via Telnet:
EXIT
Exits from Telnet

For example, to set the Power Up Status Page option to NO, the
following would be required:
Setup the Print Server as for normal TCP/IP operation regarding
Internet Address etc. and then use SMIT to add a host with the PeNetTM
Print Server’s Host Name. Add a remote queue and specify
Destination Host (as above) and Queue, on Remote Printer=Pport1 (or
other PeNetTM Print Server port). Set the Remote Device To Add to the
Printer Name for this printer.
SET PU = NO
Technical Note: The Print Server unit responds to Telnet Data
in accordance with RFC 854 on the standard Telnet Port, 23
(decimal).
To print, use the following command: LPR -P printer name file.txt
5.3.3 Printing Using FTP
5.3 Printing within TCP/IP
It is also possible to print files to the Print Server using FTP (File
Transfer Protocol). Typically this would be achieved by instigating an
FTP session, as the sequence of commands below shows:
There are two main methods of printing documents to the Print
Server using the TCP/IP protocol:
•
•
PRR
FTP
Berkeley remote LPR (LPD daemon)
File Transfer Protocol
ftp hostname where hostname is the Print Server to connect to
put filename
quit
NOTE: Printing from ‘LP’ or ‘LPR’ on Unix V systems, is only
possible if an application program is available to re-route
print data to the LPR socket.
5.3.4 Printing From SCO UNIX
SCO Unix no longer supports remote LPR so the FTP method of
printing will need to be used. A script file can be created to automate
this process as shown below:
5.3.1 Printing using LPR
The typical command line for sending a print via remote LPR to the
PeNetTM Print Server would be:
TMPFILE=/tmp/ftpprint.$$
printer=laserprt $(0)
LP -d printdef file.txt where printdef is the printer name
defined in a printcap file, with
/usr/spool/lp/model/standard “$@”>$TMPFILE
ftp -n $printer <<END
binary
:rm=Host Name and :rp=Port Name
put $TMPFILE
quit
rm $TMPFILE
exit
The LPQ and LPSTAT commands are supported by Print Server by
returning “No Entries”
5.3.2 Printing From IBM AIX
The script intercepts the print command and redirects the output to
a temporary file. FTP then sends this file to the host before deleting it
and exiting from the script file.
Printing from AIX using LPR is possible. The necessary setup is
performed with a utility called SMIT.
Technical Note: The Print Server unit supports the LPR protocol
as defined in RFC 1179 and FTP as defined in RFC 959. The unit
responds to LPR data sent to socket 515 and FTP data sent to
socket 20.

5.4 Upgrading withinTCP/IP
5.5 Troubleshooting within TCP/IP
To use the FTP based method of FLASH upgrade, it is firstly necessary
to establish an FTP connection to the Print Server in the same way as
that used when printing to the unit via FTP. Typically this will be
achieved as follows:
The following hints should help you if trouble arises when using the
Print Server. If you experience additional problems, contact Patton
Technical Support M-F, 8:30 - 5:00 PM EST at (301) 975-1007.
General
FTP xx.xx.xx.xx where
xx.xx.xx.xx is the unit’s Internet Address
No Power LED
Once connection is achieved in this way, the Print Server will
respond with a prompt requesting the USER NAME to be supplied.
When printing to the unit, this field may be ignored but when preparing
to perform a FLASH upgrade, it is the response to this field that
indicates an upgrade is being performed. To continue with the upgrade
procedure, the user must enter:
1) Check that external power supply adapter is correct type and is
functioning correctly.
2) Ensure DC connector to the Print Server is seated correctly.
3) If you are relying only upon interface power on pin 18 of the
Centronics interface, be sure the output is 5 V DC (TTL Spec.).

followed by carriage return. It is now necessary to transmit the new
operating system to the Print Server. The units new operating system
will be supplied on a single 3.5 inch diskette which will contain a single
file called IMAGEnnn.BIN (where nnn is the version number of the
upgrade). This file is typically transmitted to the Print Server using the
PUT command as shown below:
Status Page Not Printed
1) The status page prints only within 30 seconds of power-up or when
forced by software (see Section 5.2.1)
2) The power-on status page option may be disabled (see Section
5.2.1)
PUT IMAGE.BIN
Assuming that the file transfer was completed correctly, the Print Server
will respond to the end of transfer with the message:
3) The Postscript printer option may be set incorrectly for your printer
(see Section 5.2.1)
FILE TRANSFER COMPLETE - Upgrade continues when FTP is quit
4) Your printer may have a large internal buffer, in which case the
status page may have spooled to your printer but is waiting for a
timeout or command in order to print. (Check your Printer manual.)
Quitting FTP will now cause the FLASH upgrade to occur, and after a
few seconds, the unit will reboot and begin operating using the newly
downloaded operating system.
TCP/IP Specific
Print Server Will Not Respond To PING
1) Ensure the units Internet Address has been correctly set
Check the hosts ARP table is correct
