2.1.5Mounting the SMART-AG

The SMART-AG is a single-frequency GNSS receiver and antenna.

When installing the SMART-AG:

•Choose a location that has a clear view of the sky so that each satellite above the horizon can be tracked without obstruction. (Refer to the Multipath section in the GPS+ Reference Manual).

•Mount on a secure, stable structure capable of safe operation in the specific environment. Typical installation is the tractor cab roof, ideally on the steering point of the tractor.

2.1.6Connecting Data Communications Equipment

In order to communicate with the receiver, by sending commands and obtaining logs, a connection to some form of data communications equipment is required. The default configuration available is shown in Table 3, below, and its pin-out table is in Appendix A on Page 54.

2.2Additional Features and Information

This section contains information on the additional features of the SMART-AG, which may affect the overall design of your receiver system.

2.2.1MKI and PPS Strobes

An input (MKI) and ouput (PPS) strobe provide status and synchronization signals. PPS is a 3.3V CMOS output; MKI is an SV logic tolerant input.

Pin-out information can also be found on Page 54.

2.2.2Status Indicators

LED indicators on the SMART-AG provide the status of the receiver. They represent these categories:

•Position Status

•Position Type

•Power

Table 4, SMART-AG LED Status Indicators on Page 24 shows the meaning of the LED states in the expected sequence after power is applied.
