I fully agree with Alex. My previous mail was perhaps not clear on
this subject, but the main reason indeed to have different connectors
(no DB9) on the network side was/is to avoid wrong connections.
For me (again) it does not matter which connector (I know which side
of the soldering iron is hot ;-) ), as long as it isn't a DB9.
Come to think of the whole thing, there is another connector that
could be used. The audio equipment that Alex mentioned brought back
old memories (time flies). A microphone connector has three wires plus
a ground, perhaps this connector can be used.
I suggest we let Patrick 'Patsie' Lina make a choice from the now
available options:
(1) tulp
(2) DIN
(3) microphone connector (I don't know the 'technical' name)
Patrick 'Patsie' Lina, make your choice and mail us the connections!
