Product Overview
The DeviceMaster FreeWire is a high-performance, standalone device designed to
connect a wide range of serial devices (i.e., security devices, telecommunications
equipment, modems, data display devices, industrial instrumentation, etc.) to an
Ethernet network. The DeviceMaster FreeWire supports RS-232 serial interfaces
at a variety of baud rates (data transmission speeds), automatically senses both
100baseTX Fast Ethernet and 10baseT Ethernet network connections, and the
wireless capability allows connections to 802.11g wireless networks as well.
DeviceMaster FreeWire Requirements
To use the wireless DeviceMaster FreeWire, you need an 802.11g compatible
wireless network consisting of either of the following:
• An 802.11b/g wireless-enabled PC connected directly to the DeviceMaster
FreeWire (Ad-Hoc or Peer-to-Peer mode).
• An 802.11b/g wireless access point that allows wireless and wired Ethernetenabled PCs to connect to the serial server.
To configure the wireless DeviceMaster FreeWire, you will need the following
information from your wireless network administrator:
• Wireless mode used (Infrastructure or Ad-Hoc)
• The SSID (service set identifier) for your wireless network.
• The Radio Frequency Channel of the wireless network.
• If you are using TCP/IP (recommended for Windows networks) and are not
connected to a DHCP (Dynamic Host Configuration Protocol) server (for
obtaining an IP Address automatically), you will need a unique IP Address for
the DeviceMaster FreeWire (for example: 192.168.1.14). If the DeviceMaster
FreeWire is not on the same IP subnet as the PCs you are using, you will also
need a subnet mask and a router (default gateway) address.
• Wireless Security Settings (WEP keys, 802.1x settings, etc.)

• If the DeviceMaster FreeWire is operating properly, the LEDs will blink
momentarily and then go out, the yellow (10) and green (100) LEDs will
illuminate if the network is active, and the orange (Power) 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 the device connected to the serial port of the
DeviceMaster FreeWire.
•If the Power 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 Troubleshooting
See LED Indicators
3. Connect the DeviceMaster FreeWire to your network through a switch or hub
using a category 5 (CAT5) Ethernet cable. The DeviceMaster FreeWire IP
address must be configured before a network connection is available.
• The DeviceMaster FreeWire is configured with a static (fixed) IP address of
192.168.250.250 (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 DeviceMaster FreeWire when the
DeviceMaster FreeWire is powered on.
• If you want to use DHCP, you must configure the DeviceMaster FreeWire
for DHCP during the network configuration process.
Note: If a wired connection is established to the unit, the wireless link will be
disabled. The IP address must be within a valid range, unique to your
network, and in the same subnet as your PC.

Operating in
Bridged Network
Mode
The DeviceMaster FreeWire is capable of operating in a Bridged Networking
Mode. Under normal operations the DeviceMaster FreeWire is able to
communicate through the Ethernet or wireless interface but not both at the same
time. Using Bridging Network Mode, a single device attached to the Ethernet port
can communicate with a wireless network or device.
Configuration Placing the DeviceMaster FreeWire in Bridging Network Mode can only be done
through the Command Console. Once placed in Bridging Network Mode, telnet
and the web interface can only be accessed via the wireless interface. Since
networking settings change after enabling Bridging Network Mode, this
subsection explains how to enable this feature through the serial port, which is not
dependent on the network setup.
1. To access the Command Console, use the appropriate procedure:
• Telnet Connection

Limitations of Bridging Network Mode
Limitations of
Bridging Network
Mode
Behavior in Ad-Hoc Mode
Behavior in Infrastructure Mode
Bridging Network Mode on the DeviceMaster FreeWire is designed so that it
enables a single Ethernet device to become a wireless device. The DeviceMaster
FreeWire is unable to act as a typical wireless access point, which allows multiple
attached Ethernet devices to communicate with the wireless interface.
The DeviceMaster FreeWire works in a one-to-one mode. For example if you
connect a network enabled printer to the DeviceMaster FreeWire then wireless
devices can communicate with the printer.
If you attached the DeviceMaster FreeWire to a managed switch then a wireless
device is able to communicate with and manage the switch. Wirelessly connected
devices are not able to communicate with any device attached to the switch. If you
attached the DeviceMaster FreeWire to an unmanaged switch, you can
communicate with the first detected Ethernet device connected to that switch.
None of the other devices attached to the Ethernet switch are visible to the
DeviceMaster FreeWire’s wireless interface.
Thus the DeviceMaster FreeWire Bridging Network Mode can only be used to
attach one Ethernet device to a wireless network or device.
Ad-hoc mode allows a wireless device to connect to the DeviceMaster FreeWire as
though it were an access point. Use this mode when you want to directly connect
the attached Ethernet device to a computer via the wireless interface.
For example, if you want to connect a network enabled printer directly to a
computer via the wireless interface you would use ad-hoc mode.
Infrastructure mode allows the DeviceMaster FreeWire to connect to a wireless
access point. Use this mode when you want to connect an attached Ethernet device
to a wireless network. This mode differs from ad-hoc mode in that it allows
multiple devices to communicate with the attached Ethernet device via the
wireless interface.
For example, if you want to attach an Ethernet printer to your wireless network so
it can be accessed by multiple computers you would use infrastructure mode.

Verifying the Installation
There are several ways to verify that the serial port is functioning. This section
discusses how to test a serial device able to display ASCII characters.
Refer to the DeviceMaster FreeWire Software and Documentation CD for
procedures of how to use Test Terminal and the loopback plug to verify that the
serial port is functioning.
Use the following procedure to verify that the DeviceMaster FreeWire and the
serial device are working correctly.
1. Verify that both the DeviceMaster FreeWire and the connected serial device
are powered on and ready, and that a serial cable is properly connected
between the DeviceMaster FreeWire and serial device (i.e., transmit signal
output from the DeviceMaster FreeWire going to the receive signal input on
the serial device, ground leads connected together, etc.).
Note: Before attempting to use the DeviceMaster FreeWire, you must verify the
connection between the DeviceMaster FreeWire 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.
2. Verify that the DeviceMaster FreeWire port settings (i.e., baud rate, flow
control, character bit size, parity, etc.) exactly match the settings of the
connected serial device port.
3. If the serial device connected to the DeviceMaster FreeWire 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 Reset
button on the DeviceMaster FreeWire for about one second (but less than five
seconds), which initiates the output of configuration data from the
DeviceMaster FreeWire 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
DeviceMaster FreeWire’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: If the DeviceMaster FreeWire 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 DeviceMaster FreeWire 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.

Troubleshooting Installation Problems
If you cannot access the connected serial device via the DeviceMaster FreeWire,
first check the network connection and cabling.
• Check the physical cabling to ensure all cables are plugged in (Ethernet and
DB9 serial cable).
• If the appropriate LEDs (LED Indicators
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 DeviceMaster FreeWire on a different port.

Troubleshooting Network Configuration Problems
The following information may help you diagnose network configuration problems.
• If you are using TCP/IP, make sure that your PC and the DeviceMaster
FreeWire 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 DeviceMaster
FreeWire must be on the same logical network as your host PCs (e.g., if your
PC has an IP address of 192.189.207.3, the DeviceMaster FreeWire 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 DeviceMaster
FreeWire.
• If your DeviceMaster FreeWire is set to Auto or DHCP for obtaining an IP
address, it is possible that the DeviceMaster FreeWire IP address can change.
Either configure your DHCP server to give the DeviceMaster FreeWire a
permanent lease, or configure the DeviceMaster FreeWire to be on a STATIC
IP address outside the scope of the DHCP addresses.
DeviceMaster FreeWire Installation and User Guide: 2000412 Rev. D Troubleshooting - 47
Troubleshooting Windows Problems
• Check to see if you have mismatched or duplicate IP addresses. Verify that the
IP address is correctly loaded into the DeviceMaster FreeWire (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.
• Verify that the host PC and the DeviceMaster FreeWire are either on the same
subnet (for example, if the DeviceMaster FreeWire 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 DeviceMaster FreeWire.
Troubleshooting Windows Problems
• If you are having trouble accessing the connected serial device through
Windows, ensure you can ping the DeviceMaster FreeWire using the DOS
command PING ipaddress, where ipaddress is the IP address of the
DeviceMaster FreeWire. If you cannot ping the DeviceMaster FreeWire, you
will not be able to access the serial device.
• If the DeviceMaster FreeWire COM port redirector 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 DeviceMaster FreeWire to the same wireless settings.
• Make sure you have a good wireless signal from your PC and from the
DeviceMaster FreeWire, that the DeviceMaster FreeWire 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 PC is set to infrastructure mode if you are connecting through
an access point, or ad-hoc (802.11) if you are connecting to the DeviceMaster
FreeWire 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 10digit 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 Using the Web Browser Interface
DeviceMaster FreeWire. 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.
