Base System Does Not Transmit Data

The transmit LED on the front panel of the base radio will blink red each time a packet
of data is transmitted. The GPS receiver by default is set to send data to the radio
once every second. This data will be transmitted by the radio immediately. There-

c. If you find the cable properly connected, check the power level of the
power source. If low, charge the battery or replace it with a charged one
and connect it to the radio.
If using a spread-spectrum radio, power is supplied to the radio by the
GPS receiver via the RS232 connection.
d. Check to ensure that the cable connecting the radio to the receiver is
connected properly. It is recommended that the radio be connected to
the port labeled 'B' on the Z-Xtreme.
e. If the cable is properly connected, check that the receiver is turned on.
The receiver must be turned on to supply power to the radio.
