XPress Ethernet BridgeUser’s Manual
Operational Summary
The XPress Ethernet Bridge allows the user to create a long-range, wireless Ethernet network
with up to 16 active (63 total) subscriber units per access point.
Conguring a wireless link with the XPress requires the establishment of six elements:
• Each radio must know whether it is to be an access point (AP) or subscriber unit (SU).
• Each radio must have an IP address that is unique among all others on the same
network.
• The AP must know how many SUs are expecting communication with it.
• The AP and any given SU must agree on which radio frequency channel they are using.
This can be manually set or allowed to change automatically.
• The SU must be assigned a unique subscriber ID to specify which time division slot it
will use when communicating with the AP.
• The AP and any given SU must share a common 128-bit encryption key.
The access point (AP) automatically scans for the best of the 12 available radio frequency
channels, encrypts Ethernet data received from the network, and transmits it wirelessly to the
correct subscriber unit (SU). The AP is constantly monitoring the radio link and can automati-
cally change the channel if performance is degraded due to interference. If two AP units are
very close to one another, they may interfere if operating on adjacent frequency channels.
Place them at least 10 feet apart or manually select non-adjacent channels for their opera-
tion. Also, the SU should be placed at least 10 feet from the AP to avoid overloading the radio’s
receiver.
Any 10/100 BaseT Ethernet client device (ECD) can be connected to an XPress subscriber unit.
Each SU encrypts Ethernet trafc received from the attached ECD and transmits the data
wirelessly to its AP. Each SU can be plugged directly into an ECD without adding drivers or
loading software. Essentially, once the AP/SU pair is congured and running it behaves like a
continuous Ethernet cable.
XEB09-CISA(-W):
• One XEB RF Modem (“-W” = International variant)
• One 2.1 dBi Weatherproof Dipole Antenna
• One 12 VDC Power Supply
• One Power over Ethernet Injector
XEB09-CIPA(-W):
• Two each of the items above
(Ethernet cables are not included.)

Setup
1. Digital conguration is done by means of the XPress built-in browser interface. It should be
powered on and connected at least temporarily to a network containing a computer that can
run a conventional web browser.
2. Download the Digi IP Discovery Utility from our website and extract
changer_DIGI.exe from the zip archive, placing it on your desktop or in a convenient folder.
http://www.digi.com/products/wireless/xpress.jsp#docs
Note that this utility only runs on MS Windows, not linux or MAC. If you must use a non-
Windows computer for conguration, make sure your subnet mask allows your computer to
see 192.168.17.17. Connect to that default IP address with your web browser, continuing the
setup procedure with step 6.
3. Run the IP Discovery Utility, changer_DIGI.exe and you should see a window similar to this:
The XPress should appear in the list at the default IP address of 192.168.17.17. If it does not,
click “Search” to regenerate the list. If it still does not appear, you have a connection issue
and need to re-examine the cabling or you may have a rewall issue on your computer.
4. Double click the list item that refers to the XPress being congured. You should see a second
window that is similar to the picture on the next page:
1. Consult IT - each XPress radio comes default with a static IP address of 192.168.17.17. We
recommend connecting each radio to a stand-alone computer disconnected from any shared
network, and consulting with your IT dept before connecting them to any shared network.
2. Connect hardware - attach antenna to the XPress radio; attach Ethernet cable (straight or
cross-over) between the XPress radio and the “DATA + PWR” jack on the POE injector; attach
power supply to the POE injector; attach another Ethernet cable (straight or cross-over) be-
tween your Ethernet device and the “DATA” jack on the POE injector.
3. Congure radios* - use either the Digital Setup method (see below), or use the old DIP
switch method (see page 3 of the 90000888_B.pdf manual at http://www.digi.com/products/
wireless/xpress.jsp#docs).
* Note: XEB09-CIPA(-W) radios come pre-congured as a paired set. No conguration is re-
quired.

7. The admin page has sections similar to the login page showing radio statistics and device
information plus it adds several new sections. The Device Settings section allows setting the
network information and choosing an RF frequency channel. The default is to allow the radio
to choose its own frequency based on minimizing interference. If you set a xed channel,
make sure the AP and all SUs use the same one. References to DIPs on this and the next web
page refer to switches inside the radio that are used in the legacy method of conguration and
may be ignored when using the browser method.
5. Make note of the chosen IP address and password, then click “Go to Device Web Page.”
This will cause your default web browser to launch with the device IP address in the browser
address bar. Or you may launch the browser on your own and enter the web page address
manually: http://[the IP address you just set].
6. The browser page that loads rst shows the current device information and QoS statistics
and provides a login at the upper right. Log in using the password you just specied (or “pass-
word” if you kept the default). If the login succeeds, you will see an admin page similar to
this:
The information on the left is the current status of
the radio, while the boxes on the right allow you
to change it. It is important that the IP address of
the XPress is in the same subnet as your computer.
For example, if the subnet mask is 255.255.255.0
(a class C network), the rst three number groups
of the IP address must match. Choose your desired
parameters and click “Apply.”

8. On the Advanced Admin page, set the parameters as follows:
• Choose Device Type: Access Point or Subscriber Unit.
• For Subscriber Units, assign unique ID numbers in numeric order from 1 to 63.
• For an Access Point, enter the number of Subscriber Units that will be communicating
with it.
• Click the box labeled “Enable User Specied Keys.”
• Choose an 8-digit hex (0-9 and A-F) Network Name that will be common among the AP
and its SUs and enter it. The hyphen is required.
• Choose a 32-digit hex encryption key and enter it. Again, the hyphens are required.
This key must match between the AP and the SU so make a note of it as well.
After entering the parameters, click the “Apply” button to save them to the radio.
If you scroll down in the Admin browser page, you will come to three more sections:
• A graphical spectrum analyzer display that may help you to select radio channels that
avoid interference
• A section to be used if an update to the XPress rmware is required. Note that there
are two possible rmware loads for this unit, one for compatibility with older XPress
Ethernet Bridge Multipoint radios (XEB09-Bxxx), and an international version that limits
the frequency band to 915-928 MHz (Channels 7 through 12). Latest rmware is found
online at ftp://ftp1.digi.com/support/rmware/update/xpress/. To change rmware,
download the desired .bin and .webbin les, and click Upload Firmware to install
the les one at a time. Please note that we recommend contacting Technical support
before changing rmware.
• An Advanced Links section with a dire warning about advanced users only.
Despite the warning, you will need to click the “Advanced Admin” button in order to set the
device type, ID and encryption key. You should then see a page similar to this:

FCC Certication
The XPress Ethernet Bridge complies with Part 15 of the FCC rules and regulations. Compliance
with labeling requirements, FCC notices and antenna regulations is required.
IMPORTANT: The XPress Ethernet Bridge has been certied by the FCC for use with other
products without any further certication (as per FCC section 2.1091). Changes or modica-
tions not expressly approved by Digi International could void the user’s authority to operate
the equipment.
IMPORTANT: The XPress Ethernet Bridge has been certied for xed base station and mo-
bile applications. If modules will be used for portable applications, the device must undergo
SAR testing.
ANTENNAS: The XPress Ethernet Bridge is approved for use with the following weath-
erproof antennas: A09-HTM-675 (2.1 dBi dipole RPTNC male), A09-Y10TM-P10I (10 dBi Yagi
RPTNC male), A09-Y15TM-P10I (15 dBi Yagi RPTNC male), A09-Y8NF (8.1 dBi Yagi N female),
A09-Y11NF (11.1 dBi Yagi N female), A09-Y15NF (15.1 dBi Yagi N female).
9. When all of the radios are keyed and operating, connect them to your network and Ethernet
devices as desired and cycle the radio’s power to begin normal operation. Now, browser mam-
agement of the SUs can be performed over the wireless network. Note: avoid plugging actively
linked radios into the same switch because this will corrupt its routing table and may cause
network problems just as if you had plugged a CAT5 cable directly between two ports of a
switch.
