XPress™ Ethernet Bridge Multipoint: User 
Guide 
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 c

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

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. Power cycle all radios for t

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., HTTP
