Appendix A: Troubleshooting
Testing Antenna Voltage
The S-Lite antenna is an “active” antenna that requires power to operate. Power is
supplied to the antenna via the coaxial cable connecting it to the S-Lite console.
Testing the antenna voltage can ensure the S-Lite receiver is supplying power to the
antenna and can verify the antenna cable is not damaged.
To test antenna voltage:
1. Turn off the S-Lite console and then disconnect the antenna cable from the
S-Lite antenna.
2. Turn on the S-Lite console.
3. Using a voltmeter set to VDC, measure the voltage output across the
antenna cable. It should measure +5 VDC between the center conductor and
exterior connector shell.\
• If the measurement is +5 VDC across the antenna cable, then neither the
cable nor the receiver is damaged (antenna voltage test complete).
• If the measurement is not +5 VDC across the antenna cable, go to
step 4.
4. Turn off the S-Lite console and then disconnect the antenna cable from the
S-Lite console.
5. Turn on the S-Lite console.
6. Using a voltmeter set to VDC, measure the voltage output across the
antenna output on the console. It should measure +5 VDC between the
center conductor and exterior housing.
• If the measurement is +5 VDC at the console connector, but not at the
end of the antenna cable, the cable is damaged. Replace the antenna
cable and return to step 1.
• If the measurement is not +5 VDC from the S-Lite console, contact
Outback Customer Service to return the console for servicing.
Checking the DGPS Position by Verifying the
BER
You can check the bit error rate (BER) via the BER value on the Diagnostics menu.
BER is a check of correction signal reception quality and is based on a scale of 0 to
500. BER < 20 is ideal. If BER > 20 verify the antenna has a clear view of the sky to
properly find and track correction satellites. When using SBAS for the correction type,
S-Lite tracks one or two correction satellites. Each satellite has a different BER and the
BER value on the Diagnostics menu represents the values separated by a hyphen.
For example, a value of 8-500 means the S-Lite has a very good
signal on one satellite (BER=8) and is not receiving corrections
from the other satellite (BER=500, the lowest reception value).
Only one satellite must have a low BER value (less than 20) to
provide differential corrections.
