Equipment Required: IBM compatible laptop PC loaded with INSITE 6.5.1 (or later) and INSITE CENSE. INSITE CENSE is available on all INSITE installation CD-ROMs. Applicable RS232 Communication Lead:

3162850 – 9-pin serial to 9-pin serial lead (QSV81/91G <04.02) 3885817 – 9-pin serial to 3-pin RS232 lead (QSV81/91G (>04.02) &

QSK60G)

For QSV81/91G Gensets (from build >04.02 – pre-synergy models) the RS232 communication network is terminated to a terminal strip located in the Engine Interface (DC) Box (see wiring diagram bulletin 4021370). It is necessary to assemble a connection socket using Deutsch Connector Receptacle p/n 3824020 and female connector wires p/n 3822920 (see wiring diagram and picture below).

All parts required to assemble the above RS232 connector are available from the Cummins Wiring Harness Repair kits, such as 3824904.
