36     SPSx80 Smart GPS Antenna User Guide

The internal radio of the SPS GPS receiver is delivered with the transmit (Tx) radio 
frequencies preprogrammed into the receiver. To add receive (Rx) radio frequencies to 
450 MHz radios, use the WinFlash utility (see Appendix C, Adding Internal Radio 
Frequencies). Radio frequences cannot be added to the 900 MHz radios.

Once the radio frequencies are configured, use the controller or receiver to select 
channel frequencies during base station or rover setup operations.

Instead of the internal radio, you can use a cellular modem or an external radio as your 
data communications link. 

To connect a cellular modem to an SPSx80 Smart GPS antenna, you need the following:

SPSx80 Smart GPS antenna.

One of the following:

–

TSC2 controller with CompactFlash card cellular modem, for example, a 
Audiovox modem card

–

Cellular modem or a cellular phone that can transmit data

Serial (cellphone to DB9) cable (supplied with the cellular modem or phone).

Port 2 of the SPSx80 supports full RS-232 protocol, and should function properly 
with most cellular phone cables. Some cellular units may require custom 
cabling.

Alternatively, the receiver also supports a cable-free Bluetooth connection with 
Bluetooth-enabled cell phones. 

For more information on using a cellular modem as a data link, refer to the SCS900 Site 
Controller Software Getting Started Guide and SCS900 Site Controller Software Office 
Guide.
