LED Indicators
The RZ5D has 16 LED indicators for the analog and digital I/O located directly below the
display screen and DSP status LEDs.
Digital I/O
These LEDs indicate the state of the 8 bit-addressable I/O of byte C.
Analog Input - ADC LED Indicators
The ADC LED indicators are labeled and located at the top right of the RZ6
front panel. The LEDs indicate the level of the signals on ADC channels A
and B. This provides a useful indicator for adjusting the gain and to detect
and prevent clipping. The following table describes the LED indicators'
operation.
