LED's on the Detector EDC Boards

An LED is located on the rear panel of the EDC board (see Figure 5.7 on page 5-9). The LED of
the EDC board configured as DET0 (detector 1) should be flashing green at 0.5 Hz indicating that
the EDC board is up running. The LED on the EDC board configured as DET1 (detector 2) should
be flashing red at the same rate. At power up or reset, the LED will be constantly red.
A flashing red light indicates that an error was detected during power up.
