Hi, my theater used to have older version of Congo Jr, now recently we bought Congo Jr with the new Cobalt soft. We also bought Net3 rfr transmitter, but kept old receiver. Old receiver works perfectly with old transmitter and new Congo Jr Cobalt, but i can't connect new transmitter to old receiver. It just shows Search Base. Is it even possible to connect new Net3 transmitter to older receiver (i yes, then what should i do? updete firmware? how?) or should i buy new receiver?
