Overview

The XPress Ethernet Bridge (XEB) replaces costly wiring with a solution that can enable industrial

Ethernet PLCs, electronic (LED) signs, remote Wi-Fi APs, Pan/Tilt/Zoom security cameras, VoIP

phones, Internet kiosks and more. With a range of up to 15 miles (line-of-sight with a high gain

antenna) and the ability to transmit through as many as 10 standard walls, the XEB uses the added

range and capabilities of the 900 MHz band to communicate where Wi-Fi and other wireless data

products fall short.

• 1 XEB RF Modem: XEB09-BCS = Commercial (Indoor), XEB09-BIS = Industrial (Outdoor)

Accessories Kit also includes:

• 1 Half-wave, 2.5 dBi dipole antenna

• 1 6VDC/110VAC power adapter (Commercial only)

• 1 12VDC/110VAC power adapter (Industrial only)

• 1 Power over Ethernet injector (Industrial only)

• 1 XEB Multipoint manual

How It Works

The XEB radios allow you to create a long range, wireless Ethernet network for up to 16 Subscriber

Units (SU) per Access Point (AP). The AP automatically scans for the best of the 12 available radio

channels. Then it encrypts Ethernet data received from the network and transmits it wirelessly to the

correct SU. The AP is constantly

monitoring the network performance and automatically

changes channels if the performance is hindered because

of interference.

Select any of the 12 radio channels by toggling DIP switch settings. (See DIP Settings for additional

information.) It is possible to operate up to 12 APs in the same area with each AP on a different

channel. To avoid interference, space the APs at least 10 feet apart. Typically, the AP is attached to

the wired network via an Ethernet Cable. The Auto MDI/MDIX feature on each XEB will work with

either a straight through or crossover network cable.

Note: The AP does not have a MAC/IP address.

Any 10BaseT Ethernet Client Device (ECD) can be connected to an XEB SU. Each SU encrypts Ethernet

traffic received from the attached ECD and transmits the data wirelessly to its AP. You can plug each

SU directly into an ECD without need for any drivers or loading software on the ECD. Crossover cables

are never needed.

You can only attach one ECD to each SU. The DIP switches on the SU should be in the default OFF

setting. To avoid overloading the radio’s receiver, place the SU at least 10 feet from the AP. 100-foot

spacing is recommended if using high-gain antennas.

Note: The SU does not have its own MAC/IP address.

XEB radios use electronic network keys that allow you to group radios together to form a network. Network keys are shared between radios by connecting an Ethernet Cable between the RJ45 ports while the radios are in “key exchange mode” (radios that are in “key exchange mode” display the 6 LINK QUALITY LEDs blinking sequentially back and forth). Creating the Network To share the keys and to create the network, follow these steps: 1. Select which radio will be the AP by setting DIP switch 1 ON. • 2.

To Re-key a Subscriber Unit to a New Access Point Use the following procedure to re-key an SU to an AP: 1. Select the radio that will operate as the AP and set DIP switch 1 ON to enable Access Point operation. 2. Plug in the new AP. 3. Connect an Ethernet cable from the AP to the SU (key exchange will not work through a switch or hub – crossover cables are not required). 4. Plug in the SU. 5. Repeat steps 3 and 4 until all SUs are successfully programmed. 6.

Advanced Operation Contact Digi Support if your application requires: • Over 16 SUs per AP for roaming/mobility applications • Multiple APs that use the same network key for roaming/mobility • Low packet loss rates when using broadcast or multicast Ethernet packets. Note: If possible, fixed IP addresses are recommended on your network. This is because broadcast and multicast packets (e.g., DHCP, UDP) are sent once and may experience losses at extended range. Unicast packets (e.g.
