STATUS
One of the four power-supply lights
Is lit to indicate that the associated
power supply is operating properly.
The ACTIVE lights
correspond to the card’s
16 ports. When lit, an
active light indicates that
RS422 data is being
received.
The VOX lights corresponds to
the card’s 16 ports. When lit, a
VOX light indicates the audio
level on that port’s connected
audio device has exceeded a
threshold. The threshold audio
level is set for that port’s
connected audio device in EHX.
The frame data light flashes
steadily (1: 1 0.5 Hz)
when
information has successfully
passed between the CPU
card and the MVX-A16 card. The status light is lit red when the
MVX-A16 card fails to communicate
with the CPU card.
