Introduction
The Com-Server models 58631, 58641, 58633, 58031, 58034,
58231, 58431, 58432 58331 and 58334 represent a uniform
platform for linking serial interfaces such as RS232, RS422/485
to TCP/IP networks.
In addition to all the standard applications implemented in
the Com-Servers, this reference manual also describes
methods of integrating Com-Servers into your own
applications.

The list contains an overview of the most important settings.
For many applications, such as the W&T COM Port Redirector,
no additional configurations need to be made besides
assigning the network base parameters. Detailed information on
the respective parameters can be found in later sections of this
manual.

2 Assigning the IP address
The Com-Server is factory set to IP address 0.0.0.0. Before you can make
the entry in the Com-Server, you need to specify an IP address that is valid
for your network. You system administrator will provide you with this. If
you have only a small network with no routing, use the IP address of your
PC and simply change the last digit. The IP address must be unique within
the network!

14
W&T Assigning the IP address
2.1 Configuring network parameters with WuTility
The Windows tool WuTility version 3.0 and higher allows not
only inventorying of Com-Server and Web-IO installations, but
also convenient assignment of the following network-side basic
parameters:
•IP address
•Subnet mask
•Gateway address
•Activating/deactivating BOOTP/DHCP
•Activating/deactivating Web-Based-Management
Assigning requires that the PC and Com-Server be in the same
subnet. In firmware revision 1.45 the function is independent
of the current address settings in the Com-Server, i.e. even
changes to parameters not matching the network are easily
made. Any system password which has been set must however
in this case be known.
Downloading and installing WuTility
The most current version can always be found at our Web site
under the following address:
http://www.wut.de
From there use the menu tree on the left side to navigate:
Products & Downloads rCom-Servers rSoftware Tools
After unzipping the ZIP file, begin installation by double-
clicking on the file setup_us.exe. WuTility is started from
Start rPrograms rW&T Software Toolkit rWuTility
Starting the assignment dialog
First be sure that both the Com-Server and the computer you
are using are connected to the same network and are in the
same subnet. When started, WuTility automatically searches the

15
W&T Assigning the IP address
Subject to error and alteration
local network for connected W&T network devices and creates
an inventory list. This search process can be repeated manually
as often as desired by clicking on the Scan button:
Within the inventory list you can identify the desired Com-Ser-
ver based on its MAC address. For initial installations its IP
address is 0.0.0.0.
Select the Com-Server and click on the IP address button:
Enter the desired values for IP address, subnet mask and
gateway address in the corresponding fields and then click on
the Next button.

16
W&T Assigning the IP address
In the following window you can activate the BOOTP client and
the Web-Based-Management of the Com-Server.
1To prevent unintended address assignments or changes,
we recommend deactivating the DHCP, BOOTP and RARP
protocols if they are not expressly used in the respective
network environment. Com-Servers with incorrectly assigned IP
addresses can be easily found after the fact using the scan
function of the WuTility management tool and reconfigured.
Clicking on the Next button assigns the network parameters to
the Com-Server. All columns in the WuTility device list are filled
with information.
This concludes the network-side startup of the Com-Server, and
for many applications – such as use together with the COM Port
Redirector – no further settings are necessary. Special modes
or serial parameters can be set using the telnet configuration
menu or, if Web-Based-Management was used, with the help of
the Internet browser. To do this, click on either the Telnet or
Browser button:
Telnet: Browser:

1Changing network parameters is protected by the
system password. To prevent improper access, we
recommend assigning a system password for any Com-Servers
in use.
Additional information can be found in the section
Configuration Accesses for the Com-Server.

18
W&T Assigning the IP address
2.2 Assigning the IP using the ARP command
1This method can only be used if the Com-Server
does not already have an IP address, i.e. the entry is
0.0.0.0. To change an IP address, use one of the other
methods described in this section or use the configuration
menu over Telnet.
Required is a computer which is located in the same network
segment as the Com-Server and which has TCP/IP protocol
installed. Read off the Ethernet address of the Com-Server
from the sticker on the side of the housing:
58xxx [Model]
EN=00c03d004a05
OK xxxxxx
Ethernet address
Insert a static entry into the ARP table of the computer using
the following command line:
arp -s [IP address] [MAC address]
e.g. under Windows:
arp -s 172.16.231.10 00-C0-3D-00-12-FF
e.g. under SCO UNIX:
arp -s 172.16.231.10 00:C0:3D:00:12:FF
Next use the following command line under Start rRun to
start a Telnet session on the configuration port of the Com-
Server with the desired IP address:
telnet 172.16.232.10 1111 [ Return ]
1The IP addresses must be without leading zeros in
all Windows environments. Otherwise the entry is
incorrectly interpreted by the system and an incorrect IP
address is assigned to the Com-Server.
i
The IP address must
be unique within the
network.
i
Older Windows systems
only accept a static
entry if there is a
dynamic one already
present. Here you
should first ping
another network
station.

19
W&T Assigning the IP address
Subject to error and alteration
The Com-Server takes the IP address of the first network packet
sent to it as its own and saves it in non-volatile memory. The
Telnet connection will be established and the configuration
menu is displayed in the Telnet window. All further settings are
made here (see Basic configuration of the Com-Server).

20
W&T Assigning the IP address
2.3 Serial assigning of IP, subnet mask and gateway
After a Com-Server reset a time window of around 1-2
seconds is available, during which you can assign a new IP
address, subnet mask and gateway address by entering at
least 3 „x“.
1In contrast to the ARP method described above, this
serial method functions regardless of whether the
Com-Server already has an IP address or not. The procedure
can be repeated as often as desired. Therefore use this
method if you don‘t know the IP address or have forgotten it.
Appendix D contains the detailed procedure under Windows
using HyperTerminal.
First connect the serial port A of the Com-Server to a
computer. For a standard PC or laptop, you will need a
crossed RS232 cable (=Null modem cable, see RS232
interface).
The serial transmission parameters of the terminal program
you use should be set to 9600 baud, no parity, 8 bits, 1 stop
bit, no handshake. Reset the Com-Server by interrupting the
power. When the green status LED lights up, enter the letter
„x“ at least three times on the terminal, until the Com-Server
returns the prompt IPno.+<Enter>.
Use the usual format (xxx.xxx.xxx.xxx) to enter the IP
address, and end the entry by pressing <Enter>. If the entry
was accepted, the acknowledgement is the assigned IP
address. Otherwise you will get a FAIL message followed by
the last current IP address.
All other settings such as gateway address, subnet mask etc.
are done through the Telnet configuration menu (see Basic
configuration of the Com-Server).
