1. Confirm previous mode:( or )
2. Confirm any recent changes: PSU replacement, firmware change, mode change, equipment swap
Firmware Change and Control Radio Detach Test
1. Detach Swift Agent from Control Radio
2. Change mode of operation to
3. Verify whether this rectifies the issue
Diagnostics of CPU PCB Using Multimeter
1. Remove the cover on the back of the case, pull out the set of PCBs
2. Using a multimeter Diode Mode, check the USB connection lines to the Control Radio - Black probe on GND, Red probe on lines D+ D-. Infinite voltage should be shown
3. Using a multimeter Diode Mode, check the USB connection lines to the Control Radio - Red probe is on GND, Black on lines D+, D-. The multimeter should show the same (on D+ and D-) voltage decrease value, around 0.5-0.7V
4. If multimeter does not show reference values - CPU PCB is malfunction
