What's the 'pin out' for the Diagnostic port? (3.55 mm 'stereo' plug)

We'd like to log pressure from our PCG-750 gauge which has a 3.55 mm serial connection. Found nearly everything else needed in the "RS232C Serial Interface for Pirani Capacitance Diaphragm..." (Manual No. TQRa78e1), but cannot find the corresponding 'pin out' anywhere. Any help would be appreciated.
