PLATE AS 4831439 - Caterpillar

Problem Isolation
Ensure that power is removed from your base radio.
Cycle the power to the rover radio and observe the lights on the bottom of the radio. If the orange (power) and green (data) LED indicators illuminate immediately when power is applied to the radio, the radio is probably configured as a base radio and not as a rover radio. If the orange LED indicator illuminates first followed by the green LED indicator (typically 10 to 30 seconds to synchronize) the radio is probably configured as a rover radio.
Verify that the radio is configured as a rover. Cycle the power to the radio, note whether the radio synchronizes or not. If the radio does synchronize (to a base radio other than your base station radio), consider changing the network settings for all on-site radios.Intermittent Machine Radio Synchronization
Machine radio synchronization to the network is intermittent.Probable Causes
Near the outer limit of reception range of the base radio.
External jamming or interference.
Someone else is transmitting on the same network setting.
Move the base station closer to the work area.Problem Isolation
Move the machine closer to the base radio or add a radio repeater in order to add coverage. Use the following sources of information in order to verify the coverage area of the radio: AccuGrade System and AccuGrade Office.
Jamming can occur if the rover radio is in close proximity to a powerful transmitter such as another radio, or a cell phone tower.Machine Radio On Network But Not Receiving Corrections
The machine radio is synchronized to the network but the machine radio does not receive any corrections and the machine GPS remains in autonomous mode.Probable Causes
The base radio is powered and the network settings between the base radio and the machine radio are correct but any or all of the following conditions may exist:
The base GPS receiver is not plugged into the radio.
There is a port setting mismatch between the base radio and the base GPS receiver.
There is a configuration problem with the base GPS receiver and it is sending correction information out the wrong port.
The radio port settings are incorrect in the AccuGrade System.
Multiple message codes are being broadcast from the base (that is, CMR+ and RTCM). The message codes are being interleaved.Problem Isolation
Verify that the base GPS receiver and the base radio are connected securely.
Verify that the base station radio and the base GPS receiver have the identical port settings.
At the base station: under "Base Config.", confirm that only one message code is being sent to the TC series or CR series radio. For example, "RTCM Out/Off".Machine Radio Does Not Receive Corrections
The machine radio does not receive corrections.Probable Causes
The base radio and the machine radio are on a different frequency.
Wireless Data Rate (WDR) mismatch between the base radio and the machine radio.
No power to the base radio.
A transmitter failure has occurred at the base radio.
Out of the range of the base radio.
External jamming or interference.
Radio type mismatch between the base radio and rover radio.
Baud rate mismatch between the GPS receiver and either the base radio
