Introduction
1.1 About 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 units 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.

RS-232/RS-422
Functionally, the difference between RS-232 and RS-422
versions is the absence of support for hardware flow control
lines (RTS and CTS) and modem control lines (DSR, DTR and
DCD) in the RS-422 version. The performance and support
for 115.2k baud are unaffected by the different serial ports.
RS-422 uses differential signalling and is capable of handling
longer distance due to superior noise immunity when
installed with suitable cabling.
Software
description
The IOLAN+ comes with the Perle 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.

10
IOLAN + - User and Administration Guide
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.
2.1 Connecting
to your
Network
IOLAN+ and IOLAN+ connect to your Ethernet
network via one of the three auto sensing ports: 10BASE-T
(twisted pair), 10BASE2 (thin) or AUI. IOLAN+ 102/104 has
10BASE-T only. For IOLAN+ and IOLAN+ , the default
is 10BASE2.
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.
2.2 Switching on
IOLAN+
The IOLAN+ power supply accepts input voltages in the
range 110 to 240V AC, allowing it to be used world-wide.
The IOLAN+ 102/104 has an external power supply unit.
After you connect your LAN interface, you can power up the
unit. The green power indicator at the side (or front for rack
and 102/104 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.

14
IOLAN + - User and Administration Guide
The green Ethernet indicators show the active connections. It
remains lit and blinks 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+ in 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. Third party BOOTP packages are available for
Windows
®
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/98 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+.
