Can different AudioRail products interoperate on the same cable?
Most definitely yes. The AudioRail mechanism recognizes the difference between different formats (SPDIF/AES3, ADAT optical, TDIF, MIDI, SMPTE, etc.) and transports them all on the same CAT5 cable. One does not interfere with the other. Each format simply takes its share of the available bandwidth of the cable. As different AudioRail family products are introduced, the intention is that they all interoperate with each other on the same wire.
