Utility Connector (J16)
10 functions appear on the 16-pin connector at J16:
! Auxiliary power connections
! Power indicator LED
! PC speaker
! Push-button reset switch
! Standard PC keyboard interface
! External back-up battery for the real-time clock
Table 2–42 shows the pinout and signal definitions of the Utility Connector. Since there are
connections for diverse features on this single connector, a discrete-wire connector should typically
be selected rather than a ribbon cable connector, although this is not a requirement. Table 2–43
shows manufacturer’s part numbers for both types of mating connectors.
