Digi XEB09-BCS manual Creating the Network, LED Display

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.

•The other radios will function as SUs and do not require any DIP settings.

2.Connect an Ethernet Cable from the AP to each SU to transfer the network keys.

•For the Industrial/Outdoor XEB, the key exchange will occur through an Ethernet cable attached to the supplied POE injector. Key exchange will not work through a switch or hub.

Once the key sharing is complete, the AP and SU change their LED displays in confirmation of the successful programming:

The SU blinks one of the GREEN LINK QUALITY LEDS.

The AP illuminates the LED labeled RF RX, and the AP remains in “key exchange mode.”

You can add additional SUs to the network or reprogram an SU to join a different network. Likewise, an SU can be changed into an AP and an AP into an SU. If DIP 1 is accidentally toggled, it can be turned back, and the radio still retains all the network associations it had in its previous mode (assuming that the radio had not yet successfully key exchanged with a new network). You can reset an AP by programming it as an SU and then turning it back into an AP again.

SUs that have not yet received a network key boot up in “key exchange mode” and wait to receive a key. SUs that have received a network key will boot-up for 5 seconds in “key exchange mode” and will look to see if a new AP is present. If a new AP is present, then the SU exchanges keys with the AP; otherwise, the SU begins normal operation after the 5 seconds.

APs that have not yet issued network keys boot up in “key exchange mode” until they have issued network keys to at least 1 SU. Once the AP has issued keys, it will only boot-up for 5 seconds in “key exchange mode.” If an SU is present during the 5 seconds, then the AP will issue new keys to the SU and will then remain in “key exchange mode” waiting for more SUs to be attached. Once all new SUs have been attached, the AP must be power cycled. The AP will boot-up and after 5 seconds of “key exchange mode,” it will enter normal operation.
