Table 4: SMART-AG LED Status Indicators

Flashing means that the LED is turning on and off at a 1 HZ rate - 0.5 seconds on and 0.5 seconds off.

Debugging:

If the power is on but the yellow LED doesn’t flash within one minute, then no satellites are tracking. There may be excessive blockage or the unit may be defective. Make sure the unit has an unobstructed view of the sky. Try power cycling the unit.

If the yellow LED is flashing but doesn’t progress to solid yellow within one minute, then insufficient satellites are tracking or the signal quality is poor and ephemeris data can’t be received. Normally, four satellites are sufficient for a valid position as long as they are widely distributed in the sky. If it is stuck on solid yellow, there may be excessive blockage or the unit may be defective. Make sure the unit has an unobstructed view of the sky. Try power cycling the unit.

If the yellow LED is on, but the green doesn’t turn on within five minutes than no SBAS or DGPS positions are available. If you are using SBAS, make sure SBAS is available in your area and that the unit is configured to enable SBAS positions (SBASCONTROL ENABLE). For DGPS, make sure the unit is configured with the correct serial port parameters and to accept the DGPS protocol your area is using and that your data modem is connected and working.

2.2.3CAN Setup

See Section 3.1, Communications with the Receiver starting on Page 26 to begin collecting data.

Collected data can be transmitted to a host computer over a serial port using a program such as CDU. Refer to its on-line Help for details. See also the SMART-AG commands and logs, detailed in this manual.
