GPS 15 Technical Specifications (P/N 190-00266-00) Rev. BPage 72 GPS 15 WIRE DESCRIPTIONS AND WIRING DIAGRAMSThe GPS 15-F uses a six-contact flex circuit LIF (low insertion force) connector. The GPS 15-W uses a six-pin JST connector (mating wire harness included). (See Section 1.5.1.3 for details.)2.1 GPS 15 WIRE DESCRIPTIONSGPS15Pin #Signal Name Description1 BACKUP POWER This input provides external power to maintain the battery-backedSRAM and real-time clock. This enables the user to provide backuppower if needed for longer than the on-board rechargeable batterywill provide (roughly 21 days). Input voltage must be between +2.8and +3.4 Vdc.2 GROUND Power and Signal Ground3 POWER Regulated +3.3 Vdc input. Peak operating current is 75mA. Nominaloperating current is 66mA.4 PORT 1 DATA OUT Asynchronous Serial Output.CMOS compatible output designed to interface directly with a hostmicroprocessor. Provides serial data which is formatted per “NMEA0183, Version 2.20”. The baud rate is set during production to 4800,but other rates are available.5 PORT 1 DATA IN First Asynchronous Serial Input.CMOS compatible input designed to interface directly with a hostmicroprocessor. Input voltage range of 0 < V < 3.3.6 RF BIAS This input allows the user to externally apply an RF bias to the activeantenna. By default, the unit will use an internal voltage to power theactive antenna. If an external voltage greater than the internal voltageof the center pin of the antenna (between 4.0 V and 8.0 V) isdetected at this input, the GPS 15 will automatically changes to theexternal voltage. The antenna must not draw more than 60mA.Table 2: GPS 15 Wire Descriptions
