ConnectPort X2 is unable to find digimesh network

I set up a digimesh Network with 3 Xbee modules (XBee S2C) and it works fine.

Now I installed a ConnectPort X2 (DM2.4, Eth, Intl) Gateway and configurated the same PAN - ID as the existing digiemesh Network. However, the Gateway does not find any of the XBee devices. Also I wanted to configurate the ConnectPort as the coordinator, but this was not possible (this Setting is not allowed).

The Encryption is disabled, the Cycle Sleep Periode (SP) is set at 20 x 10 ms.

Anyway, where could be the Problem.

thanks a lot,


What are the full part numbers of the XBee modules in question and what firmware version is installed on each?
