Voice Erase (Audio Only)
The Voice Erase mode of operation allows the erasure of audio
information only without affecting the data.
The states of the control inputs to initiate this mode are as
follows:
STOP CVR RECORDING
- Don’t Care
PUSH TO TEST
- High
VOICE ERASE A
- Connect to VOICE ERASE C
for >2 seconds, via suitable

Flight Data Characteristics
Data Inputs
The DAFR acquires FDR data from multiple input sources.
These collectively comprise;
ARINC 429 input channels
Three ARINC 429 input channels are provided, designated
channels 1, 2 and 3. FDR parameter data is acquired from the
three inputs from label data identified in the configuration file.
Each input channel is configurable for both low and high speed.
Potentiometer Input channels
Four potentiometer inputs are supported, each consisting 3
signals, an excitation output, signal return and 0V return. Data
is sampled in accordance with the frequency, resolution, and
accuracy as required by ED112.
Excitation voltage:
3.3VDC ±0.5V
Maximum source current:
50mA
