Chapter 1: Introduction
The IEPS-1000 Device Server family provides communication between peripheral
devices and computers connected to a network. When a device server is connected to your
LAN and to one or more peripherals, it manages peripheral traffic over the network, routing
it to the correct device.
As system administrator, you will have responsibility for setting up and configuring the
device server to meet your usage requirements. The device server has been designed to
make your job easy. If you are using the serial port(s) from Systech's NativeCOM, you need
only set the IP address and related parameters. This can be done with DHCP/BOOTP or
with the NativeCOM utilities. The remaining configuration will be on the host or hosts that
are accessing the device server. The hardware is simple to install, and a browser interface
ensures that management is just as simple. In addition to configuration tools, the
communications server provides tools for monitoring and managing your port activity and
for diagnosing and troubleshooting system problems.

Chapter 2: Configuration
Device Server Configuration
Before configuring the device server, you must assign it an IP address as described below.
After it has an IP address, the device server is configured primarily through the web
browser interface. If you are using NativeCOM to access the serial ports, no other
configuration is necessary beyond setting the IP address and potentially the network mask
and gateway.
Setting the IP Address
The factory default configuration for the device server has no IP address. To use the device
server you must assign it an IP address. There are several ways to do this.
DHCP/BOOTP
If the device server does not have an IP address, or if it obtained a temporary one via the
temporary method described below, it will attempt to get one from a DHCP/BOOTP server
on the local network. If an IP address is obtained from a DHCP server, the device server will
also ask the DHCP server for a subnet mask, a default gateway, and a DNS name and server.
NativeCOM
You can also configure your device server’s IP address using NativeCOM. NativeCOM is a
Windows software package provided free of charge by Systech. The NativeCOM
Networked COM ports software makes remote serial communication ports (e.g. EIA-
232/485/422 ports on the device server) available to Windows programs as local COM
ports. Applications from a PC running Microsoft Windows 95, Windows 98, Windows NT,
Windows 2000 or Windows XP can access and use the remote serial ports. For further
information on configuring and using Networked COM ports and assigning an IP address to
your device server, see the NativeCOM manual. The NativeCOM software and manual are
available on the CD you received with your device server and from the Systech web site
(www.systech.com).
You can use the NativeCOM Configuration Utility, NativeCOM Port Server Utility, or
NCCTool to assign an IP address to your device server. Once you have done this,
DHCP/BOOTP is disabled. The NativeCOM Configuration Utility and the Port Server

Page 6
Utility always use the default subnet mask for the given IP address class. If you are
subnetting your network, the NCCTool allows you to override the default subnet mask.
Assigning a Temporary IP Address via the Network
If your device server has booted without an IP address, you can assign it a temporary IP
address using another TCP/IP system on your network. All TCP/IP systems include a
standard utility called “ARP” that can be used to assign this IP address to the device server.
The ARP command allows you to manually associate your device server’s hardware
Ethernet address (the “MAC address”) with an IP address on your network. On most Unix
and Windows systems this command looks like this:
arp-s<IP><Ethernetaddress>
<IP> is the IP address you want to assign to the device server and <Ethernet address> is the
unique Ethernet hardware address that is printed on the bottom of the device server (e.g.
“00:80:44:xx:xx:xx”). Note that under Windows, this address should be specified as “00-80-
44-xx-xx-xx” (dashes in between instead of ":" as on the label).
After you have established this ARP mapping, use ping, telnet, or a web browser to contact
the temporary IP address. The device server will see the network packets destined for its
hardware address and temporarily adopt the destination IP address from the packets. The
device server will always use the default netmask for the IP address’s class (see IP Netmask
for more information).
WARNINGS:
1. This method only temporarilyassigns an IP address. The device server will lose this
IP address when it reboots. After you have set the temporary address, you should
use a web browser to access the
2. page and permanently set the IP address.
3. This method only works if the device server does not already have an IP address.
Once the device server obtains an IP address from any other source, this method will
no longer work. To re-enable this method, you must clear out the device server’s IP
address and reboot it.
After you have permanently set the IP address on the device server, it is a good idea to
remove the permanent ARP entry that you previously added to your system. To do this,
execute the following command:
arp-d<IP>
Removing the ARP entry will not affect your ability to communicate with the device in any
way.

How to Use the Serial Ports
The device server serial port(s) can be used in several different ways:
•As Windows COM ports via NativeCOM
•As network printer ports via LPR/LPD
•They can initiate TCP/IP network connections to remote hosts (outgoing
connections) optionally using SSL security
•They can accept TCP/IP network connections from remote hosts (incoming
connections)
•They can simulate a dial-up modem connection over TCP/IP (via Modem
Emulation) also optionally using SSL security
The following sections describe each of these configurations in more detail.
If you will only be accessing the serial ports via NativeCOM, no further configuration is
necessary on the device server (unless you need to change the serial port electrical
interfaces). Otherwise, you will need to configure the desired service and set up the proper
serial parameters for your device (the device server serial ports default to 9600 baud, 8 data
bits, no parity, 1 stop bit, and no flow control).
For more information on configuring the serial settings, see the section entitled Serial
Settings.
Configuring NativeCOM Ports for Windows
The device server is pre-configured to work with NativeCOM. To use NativeCOM, select
the device server from the configuration utility and create a COM port as described in the
NativeCOM manual. NativeCOM controls the serial port settings from the host.
NOTE: NativeCOM overrides all the serial parameters set via the web browser, with the
exception of the “Require DCD” and “Electrical Interface” settings. NativeCOM requires
that the “Require DCD” setting be set to “no”, which is the default setting. If you change
this parameter, be sure to reset it for use with NativeCOM.
For more information on configuring NativeCOM ports, please see the NativeCOM
documentation.
Configuring Printers (via LPR/LPD)
All Windows and Unix systems support network-based printing via the LPD (or LPR)
protocol. Although you can also use NativeCOM or Systech RTN to indirectly set up a
network printer, it is usually preferable to use the LPD protocol because it is a simpler and
more efficient way to print. It is also easier to share a printer among multiple hosts when
using the LPD protocol.

Page 8
When configuring an LPD printer, you must provide two pieces of information to the host:
the IP address of the device server and the name of the LPD print queue. The name of the
print queue for serial port 1 should usually be port1 (or portN for serial port N). If you are
printing simple text and want to enable extra character formatting for carriage-returns and
new-lines, use fport1(or fportNfor port N).
Before configuring your host system to use LPD, be sure to configure the correct serial
parameters on the device server (see the section on Serial Settings). All ports are
automatically accessible via LPR on port 515.
To configure a printer under Windows, follow the instructions for adding an “LPR port” in
the Windows Add Printer documentation. Although this process varies depending on
which version of Windows you have, in general you must:
1. Make sure that you have installed LPR/LPD printer support
2. Select Add Printer
3. Choose to add a Local Printer
4. Create a new LPR Port
5. Specify the IP address of the device server
6. Specify the name of the print queue on the device server
To configure a printer under Unix, follow the instructions for your Unix host.
Configuring Outgoing Network Connections
The device server can be configured to initiate TCP connections to remote hosts. This
configuration can be configured for both telnet- and raw-mode protocols (with or without
SSL security). It is generally used when the device server must initiate the network
connection to the remote host.
This option can provide telnet logins for terminals attached to the device server, or it can
establish raw data paths for other serial devices. To configure a port for outgoing TCP
network connections:
1. Configure the correct serial parameters on the serial port (see Serial Settings)
2. Configure the desired TCP session parameters (see Port Services)
Configuring Incoming Network Connections via Telnet Server
The device server is pre-configured to accept incoming TCP connections from Systech RTN
for Unix or other TCP socket-based applications. Each Systech serial port accepts incoming
TCP connections on two TCP ports: an 8000-series port (for raw data), and a 9000-series port
(for telnet data).
The 8000-series port (8001 for port 1, or 800N for port N) is a raw data path that passes all
data back and forth between the network and the serial device without further processing. It
