Card LEDs
7.1.1
Connector LEDs
The bi-color LEDs behave according to definition in section 5.4 of the CoaXPress standard. Color-coded indication
along with exact timing for each indicator are shown in the following tables:
LED state
Indication
Solid green
Camera is connected, no data being transferred
Fast flash green
Camera is connected, data is being transferred
Fast flash alternate green / orange
Connection detection in progress, PoCXP active
Slow flash alternate green / orange Connection test packets being sent
Solid orange
System is not initialized
Slow pulse orange
Camera connected. Waiting for trigger event
Fast flash orange
Connection detection in progress, PoCXP not in use
Slow pulse red
No camera is connected
Solid red
PoCXP over-current

7.1.2
Board Status LEDs
LED Description
0
Alive led. Blinks when the board receives clock from PCIe
1
PCIe L0 state. When lit, indicates that the PCIe interface is powered up at active state.
2
Maximum supported PCIe gen indicator. When lit indicates that PCIe is working as Gen3 (2.4 for the Predator II
CoaXPress) When not lit the boards works either as PCIe Gen1 or Gen2 (or just PCIe Gen1 for the Predator II
CoaXPress).
3
Lane's indicator. When lit, indicates that all PCIe lanes are up. If not lit, one or four lanes are up (only one for the
Predator II CoaXPress).
