multi Funnel Fio xbee network osx

Hello,

does someone knows how to receive data from 2 differents funnel io(both using firmata) into max (maxuino or serial) using only one xbee usb explorer receiver?

I am actually on snow leopard 10.6.7

I have 2 funnel fio, both use a xbee module serie 1 and firmata as end devices.

then i got a xbee plugged into a usb xbee explorer as a coordinator/receiver.

end of the chain is max/msp with maxuino.

for the xbee config

3 modules got the Pan ID 1234

funnel xbee 1 got ID 0001

funnel xbee 2 got ID 0002

The coordinator Pan ID is 1234 there is no My ID for coordinator

and the funnel are 0 and 1 on pan ID 1234.

if i run the boards separately its working perfect.

when i got the both running, the first one connected is working with maxuino, the second one send me that message on the max windows

[arduino]_WARNING_INCOMPATIBLE_FIRMWARE_VERSION: 2

Arduino/Firmata_version: 2 2

Does Someone can help me to deal with that??

thank you

Freeka
