Signal Inputs
Analog: 2 channels balanced via screw-terminal or D-type connector

Signal Outputs
Analog: 4 (5) per input channel balanced via screw-terminal (or D-type connector)
Note: Configurable for 1 input to 8 (10) output operation

Indicators
Power up or CPU fault:
Good = Off /
Fault = Red

CPU running but input 1 not detected (both inputs or primary input when in single channel mode):
Input detected = Off /
Not Detected = Yellow

CPU running but input 2 not detected (both inputs or primary input when in single channel mode):
Input detected = Off /
Not detected = Yellow

Normal operation with input detected (either input or primary input when in single channel mode):
Input not detected = Off /
Input detected = Green

Controls
