Why
the testing for automatic loopback (PIN 140/141)
function on Scorpio1400 and Xstream1300 is not working?
Please check the DB25 - M34 cable connector.
There are two different kinds of DB25-V35female cables
although they look very similar. The correct connector
must have the pin L and pin N wired on the DB25-M34 cable
connector. (2004/02/20)
