Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide (PN S000478C)
For Hardware Versions Earlier than 2.1
Set Secondary Antenna Diagnostic Limits
Set Primary Antenna Diagnostic Limits
Set Secondary Antenna Diagnostic Limits
This example shows how to calculate and specify antenna diagnostic low and high limit values for
hardware versions earlier than 2.1. The AT+ADC command is used to read the value of the
antenna voltage divider so that the limits can be determined. Please note that this is an example
only. Your antenna characteristics may be different.
Command
Attach active GPS antenna. Enable power to the antenna.
AT+WANT=1<cr>
AT+ADC=7<cr>
Request the secondary antenna ADC voltage.
Assume a +/- 5% variance in antenna ADC reading.
Powered low limit = 200 – (.05 * 200) = 190
Powered high limit = 200 + (.05 * 200) = 210
AT+WANTLIM=1,2,0,255,190,210<cr>
Set secondary antenna diagnostic limits.
AT+WANTS<cr>
Check antenna diagnostic status.
Command
AT+WANTADC=0
Note: Enable primary antenna internal ADC as the source
Attach primary antenna.
AT+ADC=6<cr>
Request the primary antenna ADC voltage.
Assume a +/- 5% variance in antenna ADC reading.
Low limit = 130 – (.05 * 130) = 123
Open limit = 130 + (.05 * 130) = 137
AT+WANTLIM=1,1,123,137<cr>
Set primary antenna diagnostic limits.
AT+WANTS<cr>
Check antenna diagnostic status.
Attach active GPS antenna. Enable power to the antenna.
AT+WANT=1<cr>
AT+ADC=7<cr>
Request the secondary antenna ADC voltage.
Assume a +/- 5% variance in antenna ADC reading.
Powered low limit = 200 – (.05 * 200) = 190
Powered high limit = 200 + (.05 * 200) = 210
AT+WANT=2<cr>
Enable non-powered testing of the antenna.
