Visual Status LEDs
PC2-CamLink hosts two visual status LEDs on its PCI bracket. They are labeled ACQ (acquisition)
and TRIG (external trigger).
The ACQ LED indicates the status of the acquisition based on the signals going through the Camera
Link™ MDR-26 connector. Possible LED states are outlined in table below.
ACQ LED State Acquisition State
OFF Fatal card error
Static Red Camera is not connected (no Pixel Clock detected)
Static Green Camera is connected
Blinking Green Slow (2 Hz) Activity on LineValid pin
Blinking Green Fast (15 Hz) Grabbing
The TRIG LED represents the status of the selected external trigger pin. This is based on the signals
going through the DB-15 connector. The TRIG LED is also used to indicate an error condition.
Possible LED states are explained in table below.
TRIG LED State Trigger State
OFF No trigger detected
Blinking Green Triggers at a slow rate detected (one blink per
trigger)
Static Green Triggers at a fast rate detected
Blinking or Static Red Error detected by PC2-CamLink driver
Note: A PC2-CamLink application must be running to select the external trigger source for the TRIG
LED to operate. For instance, if the current camera config file selects OPTO1 as the current external
trigger source, only pulses detected on the DB-15’s OPTO1 pin will light the TRIG LED.
