One note is that on later RackInjectors, rebooting the rackinjector not only won't reboot attached devices, it also won't reboot the GPS receiver. This is to permit reboots of the control interface without affecting connected device at all. This includes *most* firmware upgrades.
So for the later boards, you'll need to reset it on the GPS status page. On Tue, Dec 31, 2019 at 6:29 PM Andreas Wiatowski <[email protected]> wrote: > Thanks Forrest, let us know what you find.
