Ron and all,

Since you have not used the KPA100 mounted externally Ron, you likely did
not know - when the KPA100 is used externally to the K2, the cable to the
computer must come off the KIO2  (TXD and RXD are sent from the K2
microprocessor and those signals are not included in the KIO2 to KPA100
connection) - the KIO2 to KPA100 connection uses only 4 signals - AUXBUS,
12CTRL, VRFDET, and 8R.

In other words, the computer side of the 'Y' cable must connect to the K2
enclosure in all cases.

73,
Don W3FPR
