Internal radio setup for rover operations
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.
Cellular modem and external radio
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.
