Hi all,
I'm still having fun restoring the two '70s acoustic couplers. They have both an RS-232 interface (DB-25F) and a 5-pin DIN (not a common type, no center pin, all pins spaced evenly on 360 degrees).
I'm guessing it's for 20mA current loop, all 5 pins have a wire connected.
I've so far reverse engineered the DB-25F pinout and looks like a standard DCE with not many signals (TX,RX,CTS,DSR,DCD,GND).
Is there a standard for these 5-pins DIN connectors that anybody is aware of?
Thanks in advance
