Adapters Array LED States – Normal Situations
The above drawings show the LEDs states of 3 daisy-chained adapters for 3 normal situations.
In the OK 1 situation, all adapters are ready to accept triggers but no triggers are sent by the
master.
In the OK 2 situation, the master adapter sends triggers and the ready signal of all adapters is
permanently high. The yellow/green toggling L2 and L4 LEDs indicate the trigger activity. The
steady green L1 and L3 LEDs indicate that all adapters are permanently ready to receive triggers.
In the OK 3 situation, the master adapter sends triggers and the ready signal of all adapters is
cycling. The yellow/green toggling L2 and L4 LEDs indicate the trigger activity. The yellow/green
toggling L1 and L3 LEDs indicate that all adapters are not ready to receive triggers for a
significant duration.
