Input/Output channel monitoring
Each channel has the following LED indicators:
Clip
Indicates clipping in the analogue domain for each input or output channel. The LED will
illuminate at +18.5dB.
Signal
The Signal LED will illuminate for each input or output channel when the signal reaches
or exceeds the signal threshold of -20dB.
Input channels have a third indicator:
48V
(Input channels only) Illuminates to in48V phantom power has been activated
for the relevant input channel. Phantom power cannot be applied to the “In” and “Out”
telephone channels, and therefore indication of phantom power is not necessary for these
channels. Instead, they have “OH” (short for “off hook”) LEDs which illuminate when the
phone is off hook.
Other indicators
COM (Communications)
The COM LED turns green to indicate a normal linked condition. The COM LED blinks
green if data is being transferred on the Ethernet or RS232 port. The LED turns yellow if a
link is established but no IP address has been established.
STAT (Status)
The STAT LED turns green when a valid design file is loaded and running. The STAT
LED turns yellow when the design is paused. The STAT LED turns red when the design is
stopped.
ERR (Error)
The ERR LED is normally off. It turns red in the case of a critical or fatal error.
PWR (Power)
The PWR LED turns blue when the device is powered on. It blinks during locate
operations (both when pressing the locate button on the rear of the device and also when
locating the device from within the software).
