Introduction

1 - Introduction
The Lantronix multi-port Fast Ethernet Print Servers (EPS2-100 and EPS4-100) are multiprotocol
print servers that provide shared network access to printers for a variety of network protocols and
operating systems. The EPS2-100 and EPS4-100 support the AppleTalk (EtherTalk), LAN
Manager, Local Area Transport (LAT), IPX (NetWare), and TCP/IP protocols. Both servers queue
multiple pending jobs and service those jobs in the order that they are received from the hosts.
NOTE: In this manual, both the EPS2-100 and the EPS4-100 servers will be
referred to as the EPS or as the Server unless a distinction needs to be
made between the models.

Installation

Connect at least one printer to the EPS using an available serial or parallel port.

If desired, connect a terminal to port 1 (the console port) to receive diagnostic and initial
configuration messages.

Connect the EPS to the 10/100BASE-T network.

NOTE: The default serial port settings are 9600 baud, 8 bit characters, and no parity.
4.

Attach one end of the power cable to the EPS; plug the other end into an electrical outlet.
Power will come on automatically.

Allow 45 seconds for the unit to fully boot. The OK LED should be lit to show the unit is
functioning properly.
If you have connected a 10BASE-T cable to the Server, the Link LED should be solid
green. If you have connected a 100BASE-T cable, The Link and 100MBit LEDs should
both be solid green. If not, check your network connection.

Print a Test page by pressing the Test/Reset button.

NOTE: If the Power LED does not light or the Test page does not print, refer to
Appendix I, Troubleshooting.

Install EZWebCon on your 32-bit Windows PC to configure your Server. The EZWebCon
software is located on the CD-ROM. See EZWebCon Configuration on page 3-2 for more
information.
2-5

Getting Started

3 - Getting Started
It is important to consider the following points before logging into and configuring the EPS:

The EPS IP address must be configured before any TCP/IP functionality is available.
(See Setting the IP Address on page 4-2.)

There are two important passwords on the EPS: the privileged password and the login
password.

Changing any server, service, or port setting requires privileged user status. The default privileged password is system.
The login password is required for remote console logins.
The default login password is access.
NOTE: If you would like to change either the privileged or login password,
either use EZWebCon or refer to the Print Server Reference Manual
located on the CD-ROM.

3-1

Getting Started

3.1 EZWebCon Configuration
The EZWebCon configuration software is the recommended way to configure the EPS.
EZWebCon is a graphical user interface that guides first time users through the initial
configuration process and allows experienced users to update and change any configurable
parameters. There are two important things to note about EZWebCon:

Your Server must have an IP address before EZWebCon can log into it for configuration purposes. See Setting the IP Address on page 4-2 for instructions.

EZWebCon requires a Java Virtual Machine (JVM) on the client. Lantronix provides
JVM installers for Solaris and 32-bit Windows users, as well as source code and
instructions for compiling it for use on other systems.

The EZWebCon software is located on the distribution CD-ROM. All instructions for installing
EZWebCon are provided in the README file. For assistance once EZWebCon is running, refer to
the EZWebCon on-line help.
NOTE: EZWebCon is also available from the Lantronix FTP and BBS servers.
See Appendix D for more information about logging into the FTP and
BBS servers.

3-2

Getting Started

3.2 Incoming Logins
Incoming logins made via EZWebCon can be used to configure the server. Incoming LAT and
TCP/IP logins can also be used.
Incoming Telnet is enabled by default to allow TCP/IP connections. To change this setting, use
the Define Server Incoming command described in the Command Reference chapter of the Print
Server Reference Manual located on CD-ROM.
Incoming logins do not prompt for a login password; therefore, you may wish to disable them. If
it is undesirable to disable incoming logins, the Server can be configured to prompt for a
password with the Define Server Incoming Password Enabled command.

3.3 Services
With few exceptions, a service must be created before print queues can be configured on the EPS.
A service is a resource accessible to network hosts. A Lantronix service is also known as a remote
printer name or remote queue name on many operating systems.
The EPS offers a default service on each port. The service names are EPS_xxxxxx_yy where
xxxxxx represents the last six numbers of the unit’s Ethernet address and yy is the port name, for
example EPS_xxxxxx_S1 (serial port) or EPS_xxxxxx_P1 (parallel port).
NOTE: The default service names are based on the server name; therefore the
server name must be no more than 13 characters.

3-3

Getting Started

The default services on the serial ports have the TCP/IP, NetWare, LAN Manager, and AppleTalk
protocols enabled. Parallel port services have TCP/IP, NetWare, and LAN Manager enabled. LAT
is disabled by default on all services provided by the Server because many network managers
object to the frequent LAT service announcements. AppleTalk is disabled on parallel port services
because AppleTalk requires Bitronics mode, which is disabled by default.
If you need to modify a default service, use EZWebCon or see the Server Configuration chapter of
the Print Server Reference Manual located on the CD-ROM.

3-4

TCP/IP Configuration

4 - TCP/IP Configuration
The EZWebCon configuration software is the easiest way to configure the EPS. The following
sections cover IP address configuration and print configuration methods for TCP/IP hosts.
NOTE: The Server needs an IP address before you can use EZWebCon. See
page 4-2 for instructions.
The EPS provides two major methods of printing via TCP/IP: Berkeley remote LPR and RTEL
host software.
Neither Windows for Workgroups nor Windows 95 support LPR directly; however, there are third
party solutions available. For more information about recommended peer-to-peer printing
solutions, see the Lantronix Windows 95 FAQ on the CD-ROM or the Lantronix web site.

4-1

TCP/IP Configuration

4.1 Setting the IP Address
The EPS IP address must be configured before any TCP/IP functionality is available.
To set the IP address, use one of the following methods: EZWebCon; a directed Ping packet; a
DHCP, BOOTP, or RARP reply; or commands entered at the command line (Local>) interface.

4.1.1 Using EZWebCon
The EPS must have an IP address before you can log into it using EZWebCon. To assign the IP
address from EZWebCon:

4-2

Start EZWebCon. Instructions for installing, running, and using EZWebCon can be found
on the distribution CD-ROM.

Click on the Lantronix logo menu in the bottom left corner of the EZWebCon window,
then select Assign IP Address to Server.

Fill in the following information:
A.

The last three bytes of the EPS’s hardware address. The hardware address is printed
on the bottom of the Server.

The desired IP address.

The subnet, if you wish to use a subnet other than the default.

TCP/IP Configuration

The IP address of the TFTP server you wish to use, if desired.

Click OK.

Cycle power on the server. EZWebCon will let you know whether the configuration was
successful.

4.1.2 Using a Directed Ping Packet
The ARP/ping method is available under UNIX, Windows 95, and Windows NT. If the EPS has
no IP address, it will set its address from the first directed IP packet it receives.
NOTE: The ARP/ping method only works during the first two minutes of EPS
operation. After two minutes, an alternate method must be used or the
EPS must be rebooted.
On a UNIX host, create an entry in the host’s ARP table and substitute the intended IP address
and the hardware address of the server, then ping the server. This process typically requires
superuser privileges.
# arp -s 192.0.1.228 00:80:a3:xx:xx:xx
% ping 192.0.1.228

4-3

TCP/IP Configuration

In order for the ARP command to work on Windows, the ARP table on the PC must have at least
one IP address defined other than its own. If the ARP table is empty, the command will return an
error message. Type ARP -A at the DOS command prompt to verify that there is at least one entry
in the ARP table.
If there is no other entry beside the local machine, ping another IP machine on your network to
build the ARP table. This has to be a host other than the machine that you're working on. Once
there is at least one entry in the ARP table, use the following commands to ARP the IP address to
the EPS and make the EPS acknowledge the IP assignment.
C:\ ARP -S 192.0.1.228 00-80-A3-XX-XXXX
C:\ PING 192.0.1.228
NOTE: There should be replies from the IP address if the ARP command
worked.
When the EPS receives the ping packet, it will notice that its IP address is not set and will send out
broadcasts to see if another node is using the specified address. If no duplicate is found, the server
will use the IP address and will respond to the ping packet.
The EPS will not save the learned IP address permanently; this procedure is intended as a
temporary measure to enable EZWebCon to communicate with the server, or allow an
4-4

TCP/IP Configuration

administrator to Telnet into the EPS. Once logged in, the administrator can enter the Change
IPaddress command to make the address permanent.
% telnet 192.0.1.228
Trying 192.0.1.228
Lantronix Version n.n/n (yymmdd)
Type Help at the ‘Local_>’ prompt for assistance.
Enter Username> gopher
Local> SET PRIVILEGED
Password> system (not echoed)
Local>> DEFINE IPADDRESS 192.0.1.228

Any host wishing to access the EPS will have to be told the EPS’s IP address. This is typically
configured in the unix file /etc/hosts or via a nameserver. Refer to the host’s documentation for
additional information.

4-5

TCP/IP Configuration

4.1.3 Using a DHCP, BOOTP, or RARP Reply
At boot time a host-based DHCP, BOOTP, or RARP server can respond to an EPS request for an
available IP address. For information about configuring the DHCP, BOOTP, or RARP server, see
your host documentation.

4.1.4 Using the Command Line Interface
1.

Connect to the serial port (Port 1) using a terminal emulation program. The serial settings
should be 9600 baud, 8 bits, 1 stop bit, no parity.

Become the privileged user and enter the new IP address.
Local> SET PRIVILEGED
Password> system (not echoed)
Local>> DEFINE SERVER IPADDRESS 192.0.1.201

TCP/IP Configuration

4.2 Notes About LPR
There are four important things to note about the LPR printing method:
1.

Because of the way the LPR protocol is typically implemented on the host, the processing
options and banner page are sent after the job data itself. The EPS will print a banner
page at the end of a job, and cannot support most of the LPR options. If it is necessary
to have the banner page at the beginning of the printout, install and use the RTEL software. If banners are not needed, they can be disabled.

The EPS cannot print multiple copies of the print job when using the -#n lpr option.

If two print queues on the host refer to two services on the same EPS, they must use separate spooling directories.

No special purpose input or output filters can be used when printing via LPR. If this functionality is necessary, use the named pipe interface program in the RTEL print queue configuration software.

4-7

TCP/IP Configuration

4.3 LPR on Windows NT 4.x
NOTE: This installation assumes that TCP/IP, Simple TCP/IP, and Microsoft
TCP/IP printing have been installed on the Windows NT host.

4-8

In the Control Panel, double-click the Printers icon.

Double-click the Add Printer icon.

In the window that appears, choose My computer and click Next.

4.4 LPR on UNIX Hosts
The Berkeley remote printing system is supported on many machines, and is simple to configure.
This section describes how to configure LPR print queues on generic UNIX hosts such as SUN
hosts. There are slight variations in LPR configuration for AIX, HP, and SCO hosts, as will be
explained in the following sections.
1.

Install a print queue on your host by adding the EPS name and IP address to the
/etc/hosts file:
192.0.1.88

EPS_xxxxxx

Add the host print queue to the /etc/printcap file:
eps_prt|Printer on LAB EPS:\
:rm=EPS_xxxxxx:\
:rp=EPS_xxxxxx_TEXT:\
:sd=/usr/spool/lpd/eps_prt:

The punctuation shown is required, and no extra spaces should be added.
4 - 15

TCP/IP Configuration

This will create a host queue named eps_prt. The rm parameter is the name of the EPS in
the host's address file, the rp parameter is the name of the service as it exists on the EPS,
and the sd parameter specifies the name of a directory used to hold temporary spooling files.
3.

Create a world-writable spooling directory using the mkdir command.
# mkdir /usr/spool/lpd/eps_prt
# chmod 777 /usr/spool/lpd/eps_prt

If desired, use the mx option to allow unlimited size files to be printed and the sh option to
prevent header pages from being generated. See the host's documentation or man pages for
more information on the format of the printcap file and how to create the spool directory.

Print to the queue using normal lpr commands:
% lpr -Peps_prt /etc/hosts

4.4.1 LPR on AIX Hosts
LPR has only been tested on AIX versions 3.2 and higher. The System Management Interface
Tool (SMIT) allows you to enable LPD printing and create print queues.

4 - 16

TCP/IP Configuration

To create a print queue:
1.

At the host prompt type smit.

Choose Print Spooling.

Choose Manage Print Server and Start the Print Server Subsystem (lpd
daemon).

In the Start the Print Server Subsystem dialog box, type both in the first field.
The message The lpd subsystem has been started will appear. Click Done.

To add a print queue:
1.

From the main window choose Print Spooling.

Choose Manage Print Server and Manage Print Queues.

Choose Add a print queue.

From the dialog box that appears choose remote.

From the next dialog box choose Remote Printing.

The Add a Standard Remote Print Queue dialog box will appear. Enter the
following information.
-

The name of the print queue,
4 - 17

TCP/IP Configuration

The name of the EPS unit,

The name of the EPS service,

The type of print spooler on the remote server, and

A description of the printer on the remote server.

A dialog box will appear with the message Added print queue eps_prt.
NOTE: If you are unable to use SMIT, see the Print Server Reference Manual
for UNIX commands for setting up print queues.
7.

Print to the queue using normal lp syntax.
% lp -deps_prt filename

4 - 18

TCP/IP Configuration

4.4.2 LPR on HP Hosts
The System Administration Manager (SAM) allows you to create print queues.
NOTE: If you are unable to use SAM, the Print Server Reference Manual
located on the CD-ROM described UNIX commands that can be used
to set up print queues.
To create a print queue:
1.

At the HP prompt type sam.

From the main application window choose Printers and Plotters.

Choose Printers/Plotters from the Printers and Plotters window.

In the pull-down menu select Remote Printer/Plotter from the Actions menu.

The Add Remote Printer window will appear. SAM will prompt you for:
-

The printer name (the name of the print queue),

The remote system name (the EPS name),

The remote printer name (the EPS service),

The remote cancel model, and

The remote status model.

4 - 19

TCP/IP Configuration

4.4.3 LPR on SCO UNIX Hosts
LPR is supported in SCO V3.2 release 4 with TCP/IP Version 1.2 and greater.
To configure a print queue using LPR:
1.

Issue the mkdev rlp command. This will install the Berkeley remote printing files and executable programs.

NOTE: The mkdev rlp command should only be issued once, or serious problems
will occur. If this happens, contact SCO technical support.
You can print to this queue using normal lp syntax once the remote printer is set up.
To create a remote printer:
1.

Issue the rlpconf command.

Answer the questions that follow. See the figure on the next page for more
information.

Make sure your hostname appears in EPS_PRT’s /etc/hosts.equivor or /etc/
hosts:lpd file.
Make sure backupprinter appears in /etc/printcap (in BSD format).
Make sure backupprinter has a spool directory on EPS_PRT.
Putting the printer in printer description file and creating spool directory... done
Updating LP information... done

The printer name is your EPS service name. The remote host name is the name of your EPS
as it is listed in your hosts file.
4 - 21

TCP/IP Configuration

During initial configuration, the queue name must be the same as the remote printer name.
However, you may change the queue name later by manually editing the printcap file.

4.5 RTEL Functionality
If the LPR method of printing is not adequate for an application (for example, if you need banners
before jobs, or more flexibility), configure the Lantronix-supplied RTEL software on the host.
After installing the software configuring the connections to the EPS, you can use normal UNIX
print commands and queue utilities such as lpc and lpstat.
NOTE: RTEL binaries are provided for many systems. Source code is also
provided for use on non-supported systems.
To print to the EPS using special formatting or using third-party software packages, you may
have to create print pipes on the host. The RTEL software provides this functionality by
providing a UNIX named-pipe interface.
To recreate the RTEL source files:
1.

Copy the file RTEL_SRC.TAR from the distribution CD-ROM to the UNIX host. Ensure
that a binary copy is performed.

Untar the archive.

4 - 22

TCP/IP Configuration

See the README files in the created directories that describe the contents of the RTEL
distribution and man pages that describe the actual software functionality.

From within the LPC administrative utility, enter these
commands to clear and reset the host queue:
abort queue_name
clear queue_name
enable queue_name
start queue_name.

4 - 23

NetWare Configuration

5 - NetWare Configuration
The EZWebCon configuration software is the easiest way to configure the EPS. The following
sections cover print configuration methods for NetWare hosts.
NOTE: The Server needs an IP address before you can use EZWebCon. See
the Setting the IP Address section on page 4-2 for instructions.
This chapter explains creating NDS print queues with NetWare Administrator and with the
PCONSOLE Quick Setup option. To create NDS print queues, you must be running NetWare
version 4.x with NDS capabilities.
If you are running NetWare versions 2.x, 3.x, or version 4.x with bindery emulation, you may
configure bindery print queues using QINST (bindery only) or PCONSOLE. For more
information, see the NetWare chapter of the Print Server Reference Manual, located on CD-ROM.

5-1

NetWare Configuration

5.1 Obtaining an NDS License
If you wish to create NDS print queues, you must read and complete an NDS registration form via
one of the following methods:

Using a forms-capable Internet browser, navigate to the Lantronix World Wide Web
site (located at URL http://www.lantronix.com) and find the NDS Registration link.

Send email to nds-info@lantronix.com. You will receive a blank registration form
that can be completed and returned to Lantronix.

If you don’t have Internet access, contact a Lantronix Technical Support representative for assistance. Contact information is provided in Appendix A -.

5.3 Creating NDS Print Queues Using PCONSOLE
1.

Type PCONSOLE at the X: prompt to start the utility.
For example, if your file server is mapped to the F: drive, you would use the F: prompt.

From the main menu choose Quick Set-Up.

PCONSOLE will prompt you for information with which to configure the print queue.
The print server name is the name of your EPS (EPS_xxxxxx). The new printer name is the
service name (for example, EPS_xxxxxx_Text). The new print queue can be any name. The
print queue volume is the name of the file server from which the printer receives print
requests. The remaining fields can be left in their default settings.

NOTE: In the above text, xxxxxx represents the last 6 digits of your EPS’s
hardware address. The hardware address is printed on the unit’s
label.

Explanation

The print server has successfully
attached to the queue

Type NETSTAT at the Local> prompt. This will display
information about fileservers, printers, and queues that the
print server has found. If a queue is in JobPoll, the print server
has successfully attached to the queue.

The DSTree, DSContext, and
DSLicense

Type Show Protocol NetWare NDS. This command shows
the tree and the context that you have configured, a failure
code, and an NDS error code for each server.
DSTree is the directory service tree on which the print server is
located. DSContext is the context where the print server is
located; it must match the context on the file server (The
DSContext must be of the following form: ou=fruit.o=exotic).
DSLicensed should be yes.

Printer and queue changes have
propagated through the NDS tree

It may take a few minutes for the changes to propagate. If the
print server doesn’t attach, reboot the server.

LAT Configuration

6 - LAT Configuration
The EZWebCon configuration software is the easiest way to configure the EPS. The following
sections cover print configuration methods for LAT hosts.
NOTE: The Server needs an IP address before you can use EZWebCon. See
the Setting the IP Address section on page 4-2 for instructions.
NOTE: To use LAT you must obtain a LAT license from your dealer or Lantronix
and use the Set/Define Protocol LAT License command on your EPS.
LAT print queues can be created by printing to a port or printing to a service. Printing directly to a
port requires no EPS configuration.
NOTE: Printing directly to a port is the easiest method for printing to the
EPS. If you would like instructions for printing to a service, see the
Print Server Reference Manual on the CD-ROM.

6-1

LAT Configuration

6.1 Printing Directly to a Port
1.

Create a LAT application port that references the Server port.
$ RUN SYS$SYSTEM:LATCP
LATCP> CREATE PORT LTAnnn/APPLICATION
LATCP> SET PORT LTAnnn/NODE=EPS_xxxxxx/PORT=Port_n
LATCP> EXIT

Create and start a print queue that uses the LAT application port.
$ INITIALIZE/QUEUE/START/ON=LTAnnn:/PROCESSOR=LATSYM
/RETAIN=ERROR queue_name

Add the commands to the SYS$MANAGER:LAT$STARTUP.COM file so the required
LAT devices will be recreated after each host reboot.

NOTE: LAT terminal device characteristics may have to be changed to correctly
print certain files. See your VMS documentation for more information.

6-2

LAT Configuration

Print to the queue.
$ PRINT/QUEUE=queue_name filename.txt

6.1.1 LAT Host Troubleshooting
By default, the LAT error message codes on the host are not translated into text error messages. If
a LAT job fails and appears in the queue with an eight-digit hex result code, the code can be
translated by issuing the following commands:
$ SHOW QUEUE/FULL/ALL queue_name
(note the error code nnnnnnnn)
$ SET MESSAGE SYS$MESSAGE:NETWRKMSG.EXE
$ EXIT %Xnnnnnnnn

AppleTalk Configuration

7 - AppleTalk Configuration
The EZWebCon configuration software is the easiest way to configure the EPS. The following
sections cover print configuration methods for AppleTalk hosts.
NOTE: The Server needs an IP address before you can use EZWebCon. See
the Setting the IP Address section on page 4-2 for instructions.
NOTE: Macintoshes that do not support EtherTalk will need either an Ethernet card or a LocalTalk-to-EtherTalk router to use the EPS.

7.1 Bitronics
The EPS advertises its printer as a LaserWriter. Therefore, printing from a Macintosh is only
possible with a PostScript printer and bi-directional communication between the EPS and that
printer.
NOTE: MacOS 8.1 can also print via LPD. See the Print Server Reference Manual
located on CD-ROM for configuration instructions.
The EPS supports the Bitronics interface, an extension to the standard Centronics interface.
Printers that support Bitronics allow bi-directional communication via the parallel port. To enable
Bitronics on an EPS parallel port, use the Define Port n Bitronics Enabled command.
7-1

AppleTalk Configuration

7.2 Macintosh Services
Before attempting to print from a Macintosh, ensure that AppleTalk and PostScript are both
enabled on at least one service. Once the service is configured, it will appear in the Chooser in the
same zone as the EPS. Select the service in the Chooser and complete the appropriate setup
options. Then close the Chooser window and print a test page of text to the Macintosh service.

7.3 AppleTalk Zones
If there is a router on the network, the EPS will appear in the default zone specified by the router.
To change the default zone use the Define Protocol AppleTalk Zone command.
If the EPS is attached to a network without an AppleTalk router, all AppleTalk devices (including
the EPS) will appear in the default zone in the Chooser.
NOTE: If no router is present on the network, the EPS will not accept AppleTalk
print jobs for 60 seconds after booting.

LAN Manager/DLC Configuration

8 - LAN Manager/DLC Configuration
The EZWebCon configuration software is the easiest way to configure the EPS. This chapter
explains DLC configuration for Windows NT 4.x hosts. Windows 95 does not support DLC
printing (see Chapter 4, TCP/IP Configuration, for more information).
NOTE: The Server needs an IP address before you can use EZWebCon. See
the Setting the IP Address section on page 4-2 for instructions.
NOTE: Printing using an LPD client is the preferred method for sending print
jobs to the EPS. To print using the TCP/IP protocol see the Using the
Command Line Interface section on page 4-8.

8.1 DLC Configuration
8.1.1 Server Configuration
To use the DLC protocol, you must have one service with the DLC characteristic enabled. Use the
Define Service servicename DLC Enabled command. The DLC characteristic may be associated
with only one service on a given EPS.

8.1.2 Host Configuration
To send print jobs from a Windows NT host to the EPS, add the EPS as a Windows NT printer.
8-1

LAN Manager/DLC Configuration

Double-click the Printers icon in the Control Panel.

Double-click the Add Printer icon.

In the window that appears select My Computer and click Next.

Explanation

Physical connection

To test a non-PostScript printer use the Test Port 1 Count 100
command. This command will send 100 lines of test data out
the parallel port.

Service characteristics

Use the Show Service Local Characteristics command from
the Server’s Local> prompt to see if the desired service is
available and to verify that the appropriate protocols are
enabled on the service.

The IP address

The IP address must be unique on the network. Many problems will occur when there are duplicate IP addresses on the
network.

Queue Status and Port counters

Use the Monitor Queue command to ensure queue entries
appear in the job list. If an entry does not appear, refer to the
appropriate host section in this Appendix.
Use the Monitor Port n Counters command to verify that the
counter is incrementing with each job. If it is not, verify the
connection between the Server and the printer.

Troubleshooting

I.3 BOOTP Troubleshooting
If the BOOTP request is failing and you have configured your host to respond to the request,
check these areas:

Table I-3: BOOTP Troubleshooting
Area to Check

Explanation

BOOTP is in your system’s
/etc/services file

BOOTP must be an uncommented line in the /etc/services file.

The Server is in the loadhost’s
/etc/hosts file

The Server must be in this file for the host to answer a BOOTP or
TFTP request.

The download file is in the correct
directory and is world-readable

The download file must be in the correct directory and world-readable. Specify the complete pathname for the download file in the
BOOTP configuration file or, a add a default pathname to the
download filename.

The Server and host are in the same

I-5

Troubleshooting

I.6 PostScript Problems
PostScript printers will silently abort jobs if they detect an error.

Table I-6: PostScript Troubleshooting
Area to Check

Explanation

The Server is communicating
with the printer

To test a PostScript printer use the Test Port 1 PostScript Count 2.
This command will send 2 pages of PostScript data out the parallel
port. Watch the indicators on the printer to verify that the Server is
communicating with the printer.
If the printer is capable of bidirectional communication, use the Test
Service EPS_xxxxxx_PS PostScript Count 5 command. This will
transfer data both to and from the printer. Autoselection must be disabled and the printer must be configured as a PostScript printer for this
test to succeed.

The printer is configured to use
8-bit characters

If special characters or bitmaps are not printing correctly, the printer
may be incorrectly configured to use 7-bit characters.

Service Characteristics

Issue the Show Service Characteristics command. If the service rating is zero, the parallel port is in use. Verify that the PostScript characteristic and appropriate protocols have been enabled on the service.

I-6

Troubleshooting

Table I-6: PostScript Troubleshooting, cont.
Area to Check

Explanation

Port Counters

If PostScript jobs appear to print but nothing comes out of the printer,
verify the amount of data sent from the host. Issue the appropriate print
command from the host system. After the job has completed, use the
Show Port 1 Counters command.
The bytes output value should be approximately 171 bytes greater than
the size of the file on the host system. These numbers are only approximate, but will show that data is flowing to the printer.

I.6.1 Bitmap Graphics
If files that contain embedded bitmap graphics print incorrectly, it is because the bitmaps are
being sent as actual binary data and binary data cannot be printed via serial or parallel interfaces.
Most major application packages have provisions to print using either binary postscript (for
printers connected to the network via LocalTalk) or hex postscript (for printers connected to the
network via a serial port or parallel port). If your application does not have this provision, ask the
application vendor for an upgrade version or patch that will add the hex postscript function.

I-7

Pinouts

J - Pinouts
J.1 Parallel Information
Lantronix uses standard Centronics parallel connectors.
For optimum performance of your Server, Lantronix recommends the use of high quality parallel
cables. Choose one of the following:

A Lantronix parallel port cable, part number #500-011 (6 feet).

Any other brand of IEEE Std 1284-1994 compliant cable. Compliant
cables can easily be identified by the permanent label IEEE Std 1284-1994
compliant on the cable itself.

NOTE: Non-compliant cables have the same type of connectors but different
electrical characteristics.

J.2 Serial Information
Lantronix servers are RS-423 compliant, and are thus limited by the equipment at the remote end
of the serial line. If the Server is connected to an RS-232 device, it is subject to RS-232 limits:
15m (50 ft.) in length at 9600 baud, and to 2m (6 ft.) at 115.2K baud, although they will generally
work at longer lengths.

Pinouts

Figure J-1: Pinout of RJ45 Serial Ports

J.2.1 RJ45 to DB25
If you are connecting an RJ45 port to a DTE device (such as a terminal) that has a DB25
connector, you will need to use an RJ45-DTE DB25 adapter. To connect an RJ45 port to a DB25
connector on a DCE device, you will need an RJ45-DCE DB25 adapter. The pinout information
for both connections is shown in Figure J-2.

J-2

Pinouts

Figure J-2: Pinouts of RJ45-DB25 Connections

The arrows in Figure J-2 represent the direction of the signal. The pinouts assume that the 8conductor cable connecting the Server and the adapter block is a swapped cable. Both the transmit
and receive ground signals on the Server connector are wired to the signal ground on a DB25
adapter.

J-3

Pinouts

A crimper block can be used to connect both transmit and receive grounds from the RJ45 cable to
the single signal ground on the DB25. The connector internally splices the two wires together and
provides one wire into the DB25 connector as shown below:

Figure J-3: Wire Splicer
Sealed at this end
RJ45 Tx Return
RJ45 Rx Return

DB9 Signal Ground

To splice the wires, cut off the end of the wire that does NOT extend through the connector and
insert both wires into the connector. Make sure that the wire that does not extend through the
connector is in as far as possible to ensure a solid connection. Make sure that the wire that does
extend through the connector extends far enough on the other side to be inserted in to the DB25
connector. Carefully squeeze the connector using a pair of pliers to make sure it is fully latched.

K.4 Reloading Software
The Server stores software in Flash ROM to control the initialization process, operation, and
command processing. The contents of Flash ROM can be updated by downloading a new version
of the operational software via NetWare, TCP/IP, or MOP. Regardless of which protocol is used to
update Flash ROM, the following points are important:

The Flash ROM software is contained in a file called EPS.SYS. The name
should not be changed.

The download file should be world-readable on the host.

There is a sixteen character length limit for the path name.

There is a twelve character limit for the filename.
K-5

Updating Software

Define commands must be used because Set configurations are cleared
when the Server boots. Use the List Server Boot command to check settings before rebooting.

NOTE: It is very important to check the Server settings before using the Initialize
Reload command to ensure that you are reloading the correct software file.

K.4.1 Reloading Sequence
If DHCP, BOOTP, or RARP is enabled on the Server, the Server will request assistance from a
DHCP, BOOTP, or RARP server before starting the download attempts. The Server will then try
TFTP, NetWare, and MOP booting, in that order, provided that it has enough information to try
each download method.
Downloading and rewriting the Flash ROM will take approximately two minutes from the time
the Initialize command is issued. If the download file cannot be found or accessed, the Server can
be rebooted with the code still in Flash ROM. As noted in Chapter 2, the OK/ACT LED will blink
quickly while the Server is booting (and reloading code) and then slowly when it returns to normal
operation.
NOTE: If you experience problems reloading Flash ROM, refer to Troubleshooting
Flash ROM Updates on page K-10.

K-6

Updating Software

K.4.2 NetWare
The EPS.SYS file should be placed in the login directory on the NetWare file server. The Server
cannot actually log into the file server (since it knows no username/password); it can only access
files in the login directory itself. On the Server, specify the file server name, filename, and path.
Local> SET PRIVILEGED
Password> SYSTEM (not echoed)
Local>> DEFINE SERVER NETWARE LOADHOST
fileserver
Local>> DEFINE SERVER SOFTWARE SYS:\LOGIN\
EPS.SYS
Local>> INITIALIZE RELOAD

K.4.3 TCP/IP
Before the Server downloads the new software, it will send DHCP, BOOTP, and/or RARP queries
(BOOTP and RARP queries are enabled by default). Next, the Server will attempt to download
the EPS.SYS file using TFTP (Trivial File Transfer Protocol).
If a host provides DHCP, BOOTP, or RARP support, it can be used to set the Server's IP address
(all) and loadhost information (BOOTP and RARP only). Add the Server's name, IP address,

K-7

Updating Software

hardware address, and download path and filename to the appropriate host file (usually /etc/
bootptab).
Some BOOTP and TFTP implementations require a specific directory for the EPS.SYS file; in
this case the path should not be specified in the bootptab file and the file must be placed in that
directory. See your host’s documentation for instructions on how to configure the EPS.SYS file in
the directory.
If BOOTP cannot be used to configure the Server's IP parameters, configure them by hand using
the following commands listed below.
Local> SET PRIVILEGED
Password> SYSTEM (not echoed)
Local>> DEFINE SERVER IPADDRESS nnn.nnn.nnn.nnn
Local>> DEFINE SERVER SOFTWARE "/tftpboot/
EPS.SYS"
Local>> DEFINE SERVER LOADHOST nnn.nnn.nnn.nnn
Local>> LIST SERVER BOOT
Local>> INITIALIZE RELOAD
NOTE: For instructions on how to log into the Server and enter these commands,
refer to Chapter 6, TCP/IP Configuration.

K-8

Updating Software

The path and filename are case-sensitive and must be enclosed by quotation marks. When
attempting to boot across an IP router, you must configure the router to proxy-ARP for the Server,
or use the bootgateway feature. For more information, see Set/Define Bootgateway in the
Commands chapter of the Print Server Reference Manual on CD-ROM.

K.4.4 MOP
Copy the EPS.SYS file to the MOM$LOAD directory. The EPS.SYS filename is the only
parameter that the Server needs to reload via MOP. Make sure the service characteristic is enabled
on the host's Ethernet circuit, and then reload the server using the Initialize Reload command.
NOTE: If an error message is displayed indicating an invalid record size on the
VAX console, the EPS.SYS file was not transferred in binary mode.

K-9

Updating Software

K.5 Troubleshooting Flash ROM Updates
Many of the problems that occur when updating the Flash ROM can be solved by completing the
following steps:

Table K-1: Flash ROM Troubleshooting
Protocol

Area to Check

NetWare

Ensure the file is in the login directory. Since the Server cannot actually
log into the file server, it has very limited access to the server directories.

TFTP

Check the file and directory permissions.
Ensure the loadhost name and address are specified correctly and that their
case matches that of the filenames on the host system.
Ensure the file and pathnames are enclosed in quotes to preserve case.
Ensure that TFTP is enabled on the host; several major UNIX vendors ship
their systems with TFTP disabled by default.
