SPSx80 Smart GPS Antenna User Guide     

Features and Functions     

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.

The receiver has only one button, the Power button, represented in this manual by

The three LEDs on the front panel of the receiver indicate various operating 
conditions. Generally, a lit or slowly flashing LED indicates normal operation, a LED 
that is flashing quickly indicates a condition that may require attention, and an unlit 
LED indicates that no operation is occurring. The following table defines each possible 
LED state:
