A DB-9F connector is used at the PC, when wiring for an Eclipse HX-PiCo serial
connection. The 3.5mm jack socket is labeled RS-232 on the front of an Eclipse HX-
PiCo. Ensure that:
• The data connections of Pin 2 to jack plug tip and Pin 3 to jack plug ring are
followed.
• Pin 5 (DB-9F) goes through to the jack plug screen.
The cable will then be ready to use.
