SPSx80 Smart GPS Antenna User Guide 21
Features and Functions 2
Port 2 is a DB-9 male connector that allows for full 9-pin RS-232 communications.
Port 2 does not support power in or out. For more information on default port settings,
see Default receiver settings, page 66. For more information on connector pinouts, see
Communication specifications, page 72.
The TNC port connector is for connecting a radio antenna to the receiver internal
radio. A whip “rubber duck” antenna is supplied with the system for units with internal
UHF or 900 MHz radios. This connector is not used if you are using an external radio
receiver. For longer range operation (to provide higher gain and to raise the antenna
higher above the ground), you can use a cable to connect an external radio antenna to
the TNC port. For more information on connecting the SPSx80 Smart GPS antenna, see
the Chapter 5, Setting up the Receiver.
