Introduction
1.1About this
Guide
This guide describes the features and applications of the
IOLAN+ terminal/communications server from the level of
novice user to more experienced system installer. It includes
information about the IOLAN+ table top unit as well as the
IOLAN+ rack mount unit (form factor is the only
difference between the two).
As an experienced user, you may save yourself some set-up time
by following the instructions in the IOLAN+ Quick Start Guide
included with your package. Consult other sections in this
guide as required. Release notes are also available with this unit
(enclosed, or available from our web sites).
Note:IOLAN+ supports Windows
®
systems including
Windows NT
®
, Windows
®
95/98 and Windows
®
3.x. When
compared to Unix, there are several key features not included
with Windows
®
systems such as TFTP, dial-out socket
connections, etc. However, we have provided a briefing on
these in the applicable sections. In many cases, we will point
you to our FTP sites for the latest tips and software for IOLAN+
and Windows
®
systems.

Introduction
Software
description
The IOLAN+ comes with the Chase CD. This CD contains
the latest ‘released’ firmware and the redirector software for
Unix systems called
ioland . The firmware is a backup copy
and generally not used. The
ioland software is used for
setting up printers and dial-out modems on Unix.
The IOLAN+ uses TFTP for downloading new firmware.
tftpd is included with Unix systems such as SCO, AIX and
HP-UX but disabled by default. Consult your Unix manual
on this subject. On Windows
®
, tftpd is not provided at this
time (see our
FTP site for a shareware tftpd program).
Note: Beta copies of the ‘next’ firmware release are usually
available on web sites (consult README files before
downloading).
Regarding
ioland , for printers/modems on Unix systems, the
source code
ioland.c is provided. There are also several
binaries of
ioland ready to run for various Unix systems (i.e.
SCO, AIX, HP-UX, Solaris, etc.). The source code can be
compiled on any Unix system (consult your Unix manual
on this subject).
Note: The most recent versions of these binaries should be
available on web sites.

Installing your IOLAN+
IOLAN+ Installation 2
Below is a step-by-step guide on how to configure IOLAN+.
You can also reference the
IOLAN+ Quick Start Guide .
First connect IOLAN+ to a network then begin configuring
the unit for your application. Additional information on
configuring modems and printers follows.
2.1Connecting
to your
Network
You connect to the network via one of three Ethernet media:
10BASE-T (twisted pair), 10BASE2 (thin) or the AUI
connector. The connectors on IOLAN+ are auto sensing.
10BASE-T
(twisted pair)
Attach the RJ connector from a hub directly to IOLAN+
twisted pair port.
10BASE2
(Thin Ethernet)
Attach a BNC T connector directly to IOLAN+. If your
IOLAN+ is the termination point for the cable you need to
add a terminator. Always ensure that each segment of the
thin Ethernet cable is at least 0.5m in length. The maximum
length for a thin Ethernet cable is 185 metres.
AUI port
The AUI connector allows an external transceiver to be
connected. This allows a number of different interfaces to
connect including 10BASE5 (or thick) and fibre optic transceivers.
2.2Switching on
IOLAN+
The IOLAN+ power supply accepts input voltages in the
range 110 to 250V AC, allowing it to be used world-wide.
After you connect your LAN interface, you can power up the
unit. The green power indicator at the side (or front for rack
units) should be lit. If the unit fails to power up with the
green power indicator lit, disconnect the unit and contact
your dealer for help.

12
IOLAN + - User and Administration Guide
The green indicators next to each Ethernet connector (or front for
rack units) indicate which connector is active (default is
10BASE2). It remains lit and will blink when LAN traffic is active.
Note: To change your Ethernet media, you will need to
reboot the unit to activate the connector.
You are now ready to begin communicating with your
IOLAN+. You can connect to IOLAN+ different ways: via a
terminal or PC on port 1, or using ARP or BOOTP. Using
ARP is the preferred method for both Windows
®
and Unix,
however a terminal or PC attached to port 1 is often used.
BOOTP setup is for Unix users only and is included in the
Tips section (2.6). Choose the appropriate method for your
application.
2.3 Communicating
via ARP
IOLAN+ supports the ‘Address Resolution Protocol’ (ARP). It
allows you to temporarily connect to your IOLAN+ to assign
a permanent IP address. If you prefer to use a terminal or PC
attached to IOLAN+, skip to the next section.
From a local Unix host, type the following:
arp -s a.b.c.d aa:bb:cc:dd:ee:ff
(where a.b.c.d is the IP address you want for IOLAN+, and
aa:bb:cc:dd:ee:ff is the Ethernet address of IOLAN+, found
on the bottom of the unit itself)
On a Windows NT
®
system, the arp command is slightly
different (using dashes instead of colons):
arp -s a.b.c.d aa-bb-cc-dd-ee-ff
Whether you use Unix or Windows
®
to run arp, you are now
ready to telnet to IOLAN+.

13
Installing your IOLAN+
Here is the sequence to use:
arp -s 205.17.209.8 00:80:D4:00:33:4e
telnet 205.17.209.8
password>
local>
At the password prompt, just hit since this is not set yet.
The IP address still needs to be configured on the unit (ARP
has only allowed you to connect to the unit so far).
Note: If there are any errors, recheck both the IP and
Ethernet addresses you keyed in (this is the most common
error here). See
Troubleshooting & Maintenance
(Appendix B)
for more information on problems.
You can now skip the next section and go straight to
section
2.5,
The Menu System.
2.4 Communicating
via a
Terminal or
PC
You can connect to IOLAN+ using a terminal or PC (with a
terminal emulation package such as Hyperterm).
Connect a terminal or your PC to port 1. The IOLAN+ serial
ports are DTE type RS-232 ports. When connecting a terminal/
PC directly (without modems), the RS-232 signals need to be
crossed over (‘null modem’ cable). See the
Cabling Guide
(Appendix C) for pinout information.
For a terminal/PC to communicate with a server, set it to the
following: 9.6 kbps, eight data bits, one stop bit, software
flow control, no parity.
After powering up IOLAN+, you are prompted to enter a
‘Local login:>‘. You can just hit any character and at this
point (the character is required).

14
IOLAN + - User and Administration Guide
The next prompt displayed is local> , which is the Command
Line Interface (CLI) prompt.
Note: If there are any problems, check the cable you are
using (this is the most common error). Port 1 is configured to
provide error messages should any problems occur.
See
Troubleshooting & Maintenance (Appendix B) for more
information on problems.
You can now move to
The Menu System.
2.5 The Menu
System
You should now be at the Command Line Interface (CLI) of
the IOLAN+ as designated by the
local> prompt. If you
would like to continue in CLI mode refer to
Appendix A , but
we recommend the menu system.
Set the terminal emulation type and begin using the menus.
The following are the terminal options:
ansi, dumb, vt100, wyse50, wyse60, tvi925,
ibm3151, vt320, falco50, hp700
The default setting is ‘dumb’. To set the menu interface to
your emulation simply type
set term with your option.
Example:
local> set term ansi
To switch from the command line interface to the menu
interface, at the
local> prompt enter:
set menu
The Connections Menu should now be displayed.
This menu displays the current state of the four possible
connections. There are no active connections.
