GPS16X-HVS GPS Receiver

1. Overview

FIGURE 1-1. The GPS16X-HVS terminates in pigtails for direct

connection to our dataloggers

The GPS16X-HVS is a complete GPS receiver manufactured by Garmin

International, Inc. Campbell Scientific configures the GPS16X-HVS to work

with our dataloggers and modifies its cable so that the cable terminates in

pigtails. The pigtails connect directly to the control ports of our dataloggers.

The GPS16X-HVS includes the GPS receiver and antenna in the same housing

with one cable for the power supply and communications. The GPS antenna

must have a clear view of the sky. Generally the GPS antenna will not work

indoors.

The GPS16X-HVS is a 12-channel GPS receiver that supports FAA Wide Area

Augmentation System (WAAS) or RTCM differential GPS. Also supported is

the 1 Pulse Per Second (PPS) timing signal. The cable connections provided

with the GPS16X-HVS do not support differential GPS correction. The cable

can be modified by the user if differential correction is required.

Our CR800, CR850, CR1000, and CR3000 dataloggers typically use the

CRBasic GPS() instruction to read the GPS16X-HVS. To use the PPS

functionality, some dataloggers need an updated clock chip. The clock chip is

factory replaced (requires an RMA). Dataloggers with the following serial

numbers need an updated chip:

Datalogger Serial Number

CR1000M < 20409

CR800, CR850 < 7920

CR3000 < 3168

3. Wiring

The GPS16X-HVS connects directly to a CR800, CR850, CR1000, or CR3000

datalogger (see TABLE 3-1). Refer to Appendix B.1 if connecting the receiver

to a CR23X. Our CR5000 and CR9000X connect to the receiver via the

SC110 and an SDM-SIO4 (see Appendix C).

If the GPS16X-HVS is to be connected to a computer to change the default

settings, an A200 or SC110 cable is needed (see Appendix A).
