Power Up
Power Up
The on-board LED indicators are illustrated in Figure 5 on page 12 . Upon
power-up, the green PWR LED should light and the yellow CONF LED
should illuminate for the duration of module initialization.
Operation Indicator LEDs
With a valid input signal connected, the green on-board PWR LED and the
SIG LED (visible from the rear) should be on. A red FAULT LED indicates
an error situation and, when noted with the other indicator LEDs, can indi-
cate a specific problem area.
Table 1 describes signal output and LED indi-
cations for the various combinations.
Table 2 provides the possible input and output conditions that result from
different input signals and conditions.
