JumboSpot LED status

JumboSpot LED on daughterboard
LED status on my Jumbo spot, rev1.6 04/2018.
LED Label Color Action Description
D1 COS Yellow On while PTT on Carrier on Sense (Squelsh)
D2 PWR Green Steady Power is on
D3 SVC Red Slow Flashes Slowly After RESET button activated or power cycled flashes with a period of
about two seconds for about a minute while connecting to the host.
JumboSpot will not accept PPT transmissions in this phase.
D3 SVC Red Flashes Quickly Indicated in service (connected) to Host.
(Continues to flash during "Apply Changes" which restarts software services)
D4 PTT Red On while receiving packets
D5 D* Green DStar
D6 DMR Yellow Steady for 20 seconds On PTT yellow on for 20 seconds. I guess it means I am transmitting on DMR.
I assume the 20 secs is the time I should have the reflector locked to my ID.
How does it know this or is it just a counter? It stays on long after the
red transmit and the green receive led has expired on my transceiver.
D7 YSF Blue Yaseu System Fusion
D8 P25 Red
D9 NXDN Blue
