Appendix B - Interface
This appendix provides information on interfacing the various aspects of
your Seres smart antenna.
The main purpose of the Seres is to provide differentially corrected
position and related information to a data logging or navigation device in the
standard NMEA format. In addition to the Seres operating as a positioning
sensor, you may also have a use for the correction data received by the
internal SBAS demodulator.
The following sections detail how to interface your Seres depending on
your application.
GPS NMEA Output
When operating the Seres as a differential positioning tool, the data output
from either Seres communication port is NMEA data that provides a
variety of information, such as position, speed, satellites tracked, and more.
This is the normal data output and mode of operating the Seres.
To establish communications between the Seres and your data logging or
navigation device in this mode of operation, you must:
•
Connect Pin-2 - transmit (TX) of either Seres port to the receive pin (RX) of
the data logging or navigation device.
•
Connect Pin-3 - receive (RX) of either Seres port to transmit pin (TX) of the
other device if it is able to configure the Seres system. Otherwise, this
connection is optional.
•
Connect Pin-5 - signal ground of either Seres port to the signal return or of
the external device.
This configuration is also used for the output of RTCM data and binary
messages from either serial port.
