Communicating between BL2600s

Hi Everybody,

I need to have 5 BL2600s on one network. One BL2600 is the Central controller which must communicate with all other 4 BL2600s. Is it possible to use SPI to do this. (One is master and all others 4 are slaves). I think the BL2600 uses SPI in Rabbitnet. is it correct? if so is this still possible to use SPI to do this job?

Does anybody think that it is possible to do this job using I2C? If you have any ideas please share with me

Thank You
