Status LEDs on Matrox Rapixo CXP
Matrox Rapixo CXP has LEDs to display the status of the CoaXPress connections
and the board.
CoaXPress LEDs
Matrox Rapixo CXP has one CoaXPress LED per video input (HD-BNC)
connector. Each LED indicates the connection status between the device (camera)
plugged into the LED’s associated connector and the Host (frame grabber). Each
LED also indicates whether the device is sending data, and whether Matrox Rapixo
CXP is transmitting power to the device.
LED color and state Description
Off Matrox Rapixo CXP is not receiving power.
Orange, solid Matrox Rapixo CXP is booting. The PoCXP-device sensing circuitry has not been enabled yet.
Red, slow pulse Matrox Rapixo CXP driver has started, but nothing is connected.
Alternating green/orange, fast flash Matrox Rapixo CXP has detected a PoCXP-compliant connection.
Orange, fast flash Matrox Rapixo CXP has detected a non-PoCXP compliant connection. PoCXP is disabled.
Alternating red/green, slow flash The device is incompatible; PoCXP is enabled.
Alternating red/orange, slow flash The device is incompatible. PoCXP is disabled.
Red, solid Overcurrent was detected in the PoCXP circuitry, possibly because of a failure in the connected device or
damage to the cable. Matrox Rapixo CXP stopped sending power to the device to avoid damaging the
device or the board.
Green, solid The device is compatible and Matrox Rapixo CXP has established a connection with the device (on the
specified cable). Note that this requires an MdigAlloc() call. No data is being transferred.
Orange, slow pulse Matrox Rapixo CXP is waiting for a grab trigger. Note that this state only occurs in triggered grab mode.
Green, fast flash Matrox Rapixo CXP is receiving data from the connected device.
Red, 500 ms pulse An error occurred during data transfer.
Red, fast flash A CoaXPress system error occurred on the Matrox Rapixo CXP board. This type of error can prevent
Matrox Rapixo CXP from receiving data. For example, an error will occur if the internal auxiliary 12 V
power connector is not connected to a power source.
