FIGURE 1. GPS16-HVS GPS Receiver
1. Overview
The GPS16-HVS is a complete GPS receiver manufactured by Garmin
International, Inc. The GPS16-HVS has been configured by Campbell
Scientific (Canada) Corp. (CSI) to work with CSI dataloggers.
The CR1000, CR3000, CR800, and CR850 dataloggers use serial input
instructions and string handling functions to read, parse and store GPS data.
The CR10X, CR23X, and other dataloggers that support P15 or the SDM-SIO4
four channel serial interface can be used with the GPS16-HVS. The CR510
and CR200-series do not support serial data input. See Appendix A for
information regarding the CR10X, CR23X, CR5000, CR9000(X) and SDM-
SIO4 applications.
The GPS16-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 GPS16-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 GPS16-HVS do not support differential GPS correction. The cable
can be modified by the user if differential correction is required.
2. Wiring
Wiring for the GPS16-HVS can be done with or without the RJ45 connector.
When shipped from Campbell Scientific, the GPS16-HVS has an RJ45
connector attached to the cable end. The GPS16-HVS can be purchased with
an RJ45 adapter with flying leads, an RJ45 to DB9 RS-232 adapter, and the
C1737 mount. Table 2-1 is the wiring description for the RJ45 adapter with
flying leads. To use Table 2-2, the RJ45 connector must be cut off the cable.
