190-00228-08 GPS 16x Technical Specifications Rev. CPage 722.1 GPS 16x PINOUTGPS 16x WIRING AND PINOUTSThe GPS 16xLVS and GPS 16xHVS sensors utilize an 8-pin RJ-45 plug. The following is a functional descriptionof each wire in the cable assembly.RJ-45Pin#WireColorSignalName Description1 Red POWER GPS 16xLVS: Regulated +3.3 to +6 Vdc. Typical operating current is 80 mA.An internal 6.67 Vdc transient zener diode and a positive temperature coefficientresistor protect from transients and over-voltages. With voltages greater than 6.8Vdc the zener will draw several amps of current through the resistor, causing it toheat rapidly and eventually power the unit off, unless an external fuse blows first.When proper supply voltages are returned, the resistor will cool and allow theGPS 16xLVS to operate.GPS 16xHVS: Vin can be an unregulated 8.0 Vdc to 40 Vdc, optimized for 12Vdc. Typical operating power is 780 mW. This voltage drives a switchingregulator with a nominal 5.0 Vdc output, which powers an internal linearregulator, producing the system Vcc.2 Black GROUND Power and Signal Ground3 Yellow REMOTEPOWERON/OFFExternal Power Control Input. Active (ON) if less than 0.3 Vdc. Inactive (OFF) ifopen-circuit. Pulling this pin to ground enables the unit; leaving the pin open-circuited powers the internal regulators off and drops the supply current to lessthan 1 mA. This input is intended to be driven by an open-collector output.4 Blue PORT 1DATA INFirst Serial Asynchronous Input. RS-232 compatible with maximum inputvoltage range -25 < Vdc < 25. This input may also be directly connected tostandard 3 to 5 Vdc CMOS logic. The low signal voltage requirement is <0.6 V,and the high signal voltage requirement is >2.4 Vdc. Input impedance is between3.0 and 7.0 kΩ. This input may be used to receive serial initialization/configuration data as specified in section 4.1 Received NMES 0183 Sentences.5 White PORT 1DATAOUTFirst Serial Asynchronous Output. This RS-232 compatible output normallyprovides serial data which is formatted per NMEA 0183, Version 3.0. The NMEA0183 baud rate is switchable in the range of 4800 to 38400 baud. The defaultbaud rate is 4800.6 Gray PPS One-Pulse-Per-Second Output. Typical voltage rise and fall times are 300 ns.Impedance is 150 Ω. Open circuit output voltage is low = 0 Vdc and high = Vinin the GPS 16xLVS, and low = 0 Vdc and high = 5.0 Vdc in the GPS 16xHVSand GPS 17HVS. The default format is a 100 ms wide active-high pulse at a 1 Hzrate; the pulse width is configurable in 20 ms increments. Rising edge issynchronized to the start of each GPS second. This output provides between 800mVp-p to 1.7 Vp-p for GPS 16xLVS and 1.4 Vp-p for the GPS 16xHVS and17HVS into a 50 Ω load. The pulse time measured at the 50% voltage point willbe about 50 ns earlier with a 50 Ω load than with no load.7 Green PORT 2DATA INSecond Serial Asynchronous Input, electrically identical to PORT 1 DATA IN.This input may be used to receive serial differential GPS data formatted perRTCM SC-104 Recommended Standards For Differential Navstar GPS Service,Version 2.2 (see section 4.5 Received RTCM Data for details).8 Violet PORT 2DATAOUTSecond Serial Asynchronous Output, electrically identical to PORT 1 DATAOUT. Reserved for future use.Table 1: GPS 16x Wire Pinout
