2.1.5 Mounting 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.
2.1.6 Connecting 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.
