hi thomas, just use two unshielded twisted pairs of telephone patch wire for short distances. if you have longer distances (10 .. 100m), you should use network cables.
regards, andreas >i need a cable to connect 2 bs-11 in daisy chain mode. the web page said >120 ohm symmetric, no type or link where to buy it. must that be exactly >this spec (120 ohm), or can i take any shielded cable with 2 wires?
