Section 2: Hardware Installation
Install the Serial Server
The Serial Server can be wall mounted, set on the desktop, or mounted using the optional DIN rail kit .
Before attempting to install the Serial Server, make sure you have installed and set up your serial device
as described in the documentation that came with the device. Write down the 12-digit MAC (Media
Access Code) address printed on the label located on the bottom of the Serial Server (for example:
004017023F96). You may need this number in order to configure the Serial Server.
Connect the Serial Server to your serial device using a standard PC-compatible 9-pin (DB-9) serial cable
for RS-232 type devices (refer to Appendix A for pinout descriptions).
Plug the Serial Server power supply adapter into a suitable AC receptacle, and then plug the power
supply cable into the Serial Server. The Serial Server will run through a sequence of power-up
diagnostics for a few seconds.
 If the Serial Server is operating properly, the LEDs will blink momentarily and then go out, the
yellow and green LEDs will illuminate if the wireless network is active, and the orange LED
will illuminate, indicating the device is receiving power.
 The unit powers up in the Normal mode, which provides for connection from the network to
device(s) connected to the serial port of the Serial Server.
 If the orange LED blinks continuously in a regular pattern, a problem exists. If this is the case,
try powering the unit OFF and then ON again. If the problem persists, refer to the
Troubleshooting section in this User’s Guide.
Connect the Serial Server to your network through a switch or hub using a category 5 (CAT5)
Ethernet cable. The Serial Server’s IP address must be configured before a network connection is
available. If your network offers DHCP (Dynamic Host Configuration Protocol), the Serial Server will
automatically search for a DCHP server upon power up and obtain an IP address. If your network
does not offer DHCP, a static (fixed) IP address must be assigned (see your system administrator for
assistance). In most cases, a fixed IP address is preferred because a DHCP server may not always
assign the same IP address to the Serial Server when the Serial Server is powered ON.
The Serial Server also supports the following protocols. See your system administrator for help.
 arp
 rarp
 BootP
NOTE
: The IP address must be within a valid range, unique to your network, and in the same subnet as
your PC.
NOTE
: For wireless Serial Servers, if a wired connection is established to the unit, the wireless link will be disabled.

Interface.
 the default password is ACCESS.
 can be accessed via TELNET or via a direct connection to the Serial Server’s serial port.
 type HELP for a list of console commands.
Configuring the Serial Server via an Ethernet Connection
For Microsoft Windows operating systems, the ExtendView Utility is the recommended method of configuring one or
more Serial Servers on your network. Once the Serial Server obtains an IP address (occurs automatically when the
unit is powered ON and connected to a DHCP network), the ExtendView Utility’s auto-discovery feature will search
for and locate all Serial Severs on the network and then display the IP address for each discovered Serial Server.
Using the ExtendView Utility to Configure the Serial Sever
(Windows operating systems):
1. Start the ExtendView Utility by clicking on Start,Programs, and then ExtendView.
2. When the Welcome screen appears, click on Next, choose any name for your View Name, select
Automatically create a view with default settings (or configure the view to your preferences), and
then click on Finish.
3. Right-click on the Serial Server that you want to configure from the displayed list, and then left-click
on Configuration. The default Serial Server name is SBxxxxxx (where xxxxxx is the last six digits of
the MAC address from the label located on the back of the Serial Server).
4. If you are using TCP/IP (recommended for Windows) and you do not have a DHCP server (see note
below), you will need to manually assign a valid IP Address (if you are not sure what IP address is
valid, ask your network administrator), and then click on OK.
5. Configure the 802.11b/g wireless settings (for wireless models only). To operate on an 802.11b/g
network, the Serial Server configuration must be set to the same configuration as your wireless
network to allow the Serial Server to communicate over your wireless network. All nodes of a
wireless network need to have the same settings to allow communication between the devices.
 wireless mode (ad-hoc or infrastructure)
 SSID channel
 data rate
 wireless security settings (WEP keys, 802.1x settings, etc.)
NOTE
: If you are using DHCP on your network, the Serial Server should have acquired valid IP settings at this point
and no further configuration is necessary. However, for most installations, a static IP address is preferred. If your
DHCP server does not allow the Serial Server to keep its assigned IP address permanently, then you must manually
assign an IP address. In this case, use a static IP address outside the range reserved for DHCP (see your DHCP
server documentation for details). To assign a static IP address, right-click on the Serial Server in the menu, and
then select Configuration. On the TCP/IP tab, under IP Address Resolution, select Set Permanent, and assign a valid
static IP address for your network. Click on
OK
to save the n
ew settings.

Using the Web Browser Interface to Configure the Serial
Server (Non-Windows systems):
To configure the Serial Server using non-Windows operating systems (e.g., Unix systems), a standard web browser
(e.g., Internet Explorer or Netscape Navigator) can be used to access the Serial Server’s embedded Web (HTTP)
server pages, which contain the Serial Server’s configuration options. No additional software is required.
1. Ensure your PC is connected and has access to your network.
2. Connect an available Ethernet cable from your network hub to the Serial Server. Ensure the Serial
Server is powered ON.
3. Connect the Serial Server to the desired serial device, and ensure that the device is powered on and
ready. If the Serial Server is connected to a serial device that cannot display or print ASCII
characters, then it is recommended that another serial device capable of displaying or printing ASCII
characters be temporarily connected to the Serial Server in order to view the IP address assigned by
the DHCP server to the Serial Server.
4. With the serial device and Serial Server switched on and ready, press the Test button on the Serial
Server to send the Serial Server’s configuration data to the connected serial device. The serial
device should display or print the current IP address assigned to the Serial Server by your network
DHCP service. If your network does not use DHCP, then the Serial Server will have the default IP
address of 192.0.0.192. In any case, your computer must use an IP address other than the one used
by the Serial Server in order to establish a connection between the two devices.
5. Configure the 802.11b/g wireless settings. To operate on an 802.11b/g network, you must set the
Serial Server’s wireless mode (ad-hoc or infrastructure), SSID channel, data rate, and security
settings (WEP keys, 802.1x settings, etc.) to the same configuration as the wireless network you want
the Serial Server to communicate on. All nodes of a wireless network need to have the same settings
in order to communicate with each other.
6. From the host computer, open a standard web browser (e.g., Internet Explorer, Netscape Navigator),
enter the IP address of the Serial Server into the address bar of the web browser, and then press
Enter. The Web Browser Utility screen will be displayed. Click on the Login menu selection, enter
the password (default is ACCESS), and then click on Submit. The main screen will be displayed,
allowing you to configure the settings of the Serial Server. The menu selections are displayed on the
left side of the screen, and the individual settings are located at the top of the screen.

Using the Internal Configuration Console to Configure the
Serial Server:
1. Ensure the serial server is connected via an Ethernet cable to the host computer.
2. From the Windows Start menu, click on Run, and then type the following command (where x.x.x.x. is
the IP address of the Serial Server). The system will use the default port 23.
telnet X.X.X.X
3. After a connection is established, press RETURN or ENTER to get the "#" prompt, enter the password ACCESS
(it will not ‘echo’ on your screen), and type anything in response to the Enter Username> prompt. When the
Local> prompt appears, you are ready to enter commands.
Configuring the Serial Server via a Serial Connection
The Serial Server’s command console can be accessed via a direct connection to the Serial Server’s serial port using
a COM port emulator and a null modem serial cable.
Using the Internal Configuration Console to Configure the
Serial Server:
1. Attach one end of a null modem serial cable to the DB9 serial port of the Serial Server, and the other
end of the cable to the COM port on your computer.
2. By default, this function is disabled on the WiComm. To enable this function, you must set the
“Console Mode String” parameter on the web I/O Port page to a non-blank string. The string can also
be set via Telnet with the SET POR S1 CONSTR <string>. For example, SET POR S1 CONSTR
+++ will make the string “+++” the cue to enter this mode..
3. Start a terminal emulation program (e.g., Windows Hyper Terminal), making sure you are connecting
with the relevant COM port.
4. Use the following settings for the connection:
 BITS PER SECOND: 115200
 DATA BITS: 8
 PARITY: NONE
 STOP BITS: 1
 FLOW CONTROL: NONE
If the settings for the serial port have been changed from the factory default, use the new values
instead of the values above.
5. Once connected, type the string configured in step 2 above. The Local> prompt will appear,
indicating that the system is ready to accept commands. For a list of commands, type help at the
command prompt.

NOTE
: Be sure to set your PC back to its original wireless settings after you finish configuring t
he wireless Serial
Server.
NOTE
: It is not necessary to change your computer’s settings if you are configuring the Serial Server’s settings via
an Ethernet connection.
First-Time Configuration of the Wireless Serial Server Using 802.11b/g
Although the Serial Server can be configured using a wireless connection, it is recommended that the Serial Server
be initially configured using a wired connection as described on the previous pages. The Serial Server’s wireless
network interface supports all modes of 802.11b/g from 1 to 54 Mbps. The wireless network is only active if the Serial
Server is not connected to a wired network. If a wired link is established to the Serial Server, the wireless link is
automatically disabled. To configure the wireless Serial Server for the first time from a computer via an 802.11b/g
wireless connection, you will need to temporarily change your computer’s settings to match the default settings of the
Serial Server as follows:
 Wireless Mode: Ad-Hoc (sometimes referred to as Peer-to-Peer)
 Channel: 11
 SSID (or wireless network name): serserv
You should now be able to configure your Serial Server using either the ExtendView Utility or the Web Browser
Interface as described in the previous sections.
In addition to the standard 802.11 WEP (Wired Equivalency Privacy), SystemBase provides additional wireless
security options (refer to the security section at the end of this manual for detailed information).

WiComm User’s Guide

Verifying the Serial Server’s Connection to a Serial Device
1. Verify that both the Serial Server and the connected serial device are powered on and ready, and that
a serial cable is properly connected between the Serial Server and serial device (i.e., transmit signal
output from the Serial Server going to the receive signal input on the serial device, ground leads
connected together, etc.).
2. Verify that the Serial Server’s port settings (i.e., baud rate, flow control, character bit size, parity, etc.)
exactly match the settings of the connected serial device’s port.
3. If the serial device connected to the Serial Server is able to display or print ASCII characters (such as
a terminal emulator or serial printer), then communication between the devices can be verified by
pressing the Test button on the Serial Server for about one second (but less than five seconds),
which will initiate the output of configuration data from the Serial Server to the connected serial device.
 If communication has been successfully established between the two devices, the serial device
should be able to display or print the Serial Server’s configuration data.
 If no data is displayed or printed, verify that both devices are powered ON, are properly
connected using a suitable serial cable, and are using compatible serial port parameters. The
two most common serial communication problems are due to the either the cabling and/or
mismatched serial port parameters.
NOTE
: Before attempting to use the Serial Server, you must verify the connection between the Serial Server and the
connected serial device. If this connection is not working, you will not be able to send and/or receive data from the
connected serial device.
NOTE
: If the Serial Server is connected to a serial device that cannot display or print ASCII characters, then it is
recommended that another serial device capable of displaying or printing ASCII characters be temporarily
connected to the Serial Server in order to verify the serial connection. After successful communication is verified
using the temporary serial device, reconnect the original serial device, making sure that the original serial device is
configured with serial port parameters that match the tested connection.

Changing the Serial Settings
In order to establish communication between the Serial Server and a serial device, the serial settings for both devices
must match. The serial settings can be changed using ExtendView (recommended), the web browser interface, or
the Serial Server’s internal configuration console (refer to the previous sections for the installation and use of these
utilities). Refer to page 1-5 for a list of factory default settings.
U SING THE E XTEND V IEW U TILITY TO C HANGE THE S ERIAL S ETTINGS :
1. Start the ExtendView Utility by clicking on Start,Programs, and then ExtendView.
2. From the main menu, click on Options, and then click on Configuration.
3. Click on the Output Port tab, and then click on the Serial Settings button.
4. After configuring the serial settings, click on OK to continue.
Changing the Baud Rate
In some cases it may be necessary to change the baud rate of the serial sever in order to match the baud rate of a
particular serial device where the baud rate is fixed. Baud is a measurement of transmission speed in asynchronous
communication and represents the number of bits that are actually being sent over the media, not the amount of data
that is actually moved from one device to the other. The Serial Server supports baud rates from 300 to 460800 bps.
To ensure communication between connected serial devices, all other serial port parameters (mode, character bits,
parity, etc.) must be identical for each serial device.

Section 4: Troubleshooting
Introduction
This section describes procedures for troubleshooting problems you may encounter with the Serial Server, and is
divided into the following sections:
 Installation Problems
 Intermittent Problems
 Protocol-Specific Problems
Troubleshooting Installation Problems
If you cannot access the connected serial device via the Serial Server, first check the network connection and cabling.
 Check the physical cabling to ensure all cables are plugged in (Ethernet and DB-9 serial cable).
 If the appropriate LEDs are not illuminated, then there is probably a bad 10baseT or 100baseTX
cable, or the hub port is bad. If possible, try a different cable and hub port, or try connecting a
different device to the cable.
 Verify that you using the correct values for both IP Address and Port Number. A common
mistake is to assume the TCP port number is the "device number" on the server.
 If you are using a hub, verify that the hub port is operating correctly by trying the Serial Server on
a different port.
Troubleshooting Network Configuration Problems
 If you are using TCP/IP, make sure that your computer and the Serial Server are on the same IP
segment or can reach each other with a PING command from the host. The IP address you
assign to the Serial Server must be on the same logical network as your host computers (e.g., if
your computer has an IP address of 192.189.207.3, the Serial Server should have an IP address
of 192.189.207.x, where x is an integer between 1 and 254), or you must properly configure your
router address to work with the Serial Server.
 If your Serial Server is set to Auto or DHCP for obtaining an IP Address, it is possible that the
Serial Server’s IP address can change. Either configure your DHCP server to give the Serial
Server a permanent lease, or configure the Serial Server to be on a STATIC IP address outside
the scope of the DHCP addresses.
 The problem may be the result of mismatched or duplicate IP addresses. Verify that the IP
address is correctly loaded into the Serial Server (via the displayed or printed configuration
information or through the remote console), and make sure that no other nodes on the network
have this address (duplicate addresses are the biggest cause of TCP/IP connectivity problems).
If the IP address is not correct, then check whether the loading procedure was properly executed.
 Also verify that the host computer and the Serial Server are either on the same subnet (for
example, if the Serial Server has a subnet mask of 255.255.255.0, the host must have the same
subnet mask) or that the router is properly configured to pass data between the two devices.
 If the wrong IP address is loaded, check your network for file servers that have DHCP, BOOTP,
or rarp enabled, and make sure that these file servers are not set up to load IP addresses into the
Serial Server.

WiComm User’s Guide
Page
17
Troubleshooting Windows Problems
 If you are having trouble accessing the connected serial device through Windows, ensure you
can ping the Serial Server using the DOS command PING ipaddress, where ipaddress is the IP
address of the Serial Server. If you cannot ping the Serial Server, you will not be able to access
the serial device.
 If you are running COM port emulation software and the software reports an error, verify that the
correct serial/IP COM port is being used when the application runs. Verify that your application’s
COM port settings have been changed to use the Serial/IP COM ports.
 Troubleshooting Wireless Configuration Problems
 Verify that your PC’s wireless adapter and/or access point is configured properly – note the
settings, paying special attention to the wireless mode, SSID or network name, WEP or security,
and IP address settings so you can configure your Serial Server to the same wireless settings.
 Make sure you have a good wireless signal from your PC and from the Serial Server, that the
Serial Server is within range (90 meters or 300 feet), and that it is away from metal objects and
other devices that generate radio signals (like Bluetooth devices, cordless phones, and
microwave ovens).
 Make sure your computer is set to infrastructure mode if you are connecting through an access
point, or ad-hoc (802.11) if you are connecting to the Serial Server without an access point. See
the documentation for your wireless adapter for details.
 If you want to use WEP encryption or password protection for your wireless network, and your
wireless adapter or access point normally uses a password or passphrase instead of WEP, it
should allow you to enter 0x followed by a 10-digit key (for 40-bit or 64-bit WEP) or 26-digit key
(for 128-bit WEP) in hexadecimal format (0-9 or A-F).
 If you are experiencing slow performance or are having intermittent problems connecting, try
changing the RF channel of your wireless network. The RF channel can be changed via the
ExtendView Utility or the web browser configuration utility for the Serial Server. See your
wireless adapter and/or access point documentation for more information. When changing the
RF channel, it is recommended that you select a channel that is at least three channels lower or
higher than any other wireless networks within range.
