As long as power is provided to the 9602-LP, the GPS receiver will store ephemeris data in its memory
before powering down (sleep between reports). The ephemeris data are valid up to two hours and can be
used in future startup to improve time-to-first-fix. Unlike the 9601-DGS-LP, the 9602-LP does not need an
extra back-up battery to retain ephemeris data.
4.0 MULTI-INTERFACE CONNECTOR
The multi-interface connector on model 9602-LP is a standard male 15-pin miniature D-Sub type (DB-
15). The connector comprises of four interfaces with the pin assignments shown in Table 1. These interfaces
include:
External DC power input
3-wire RS232 serial data interface
TTL/CMOS I/Os
Reserved RS232 serial data interface
