2CONTROL section A green ETHERNET LED
illuminates to show the communication status
between unit and PC, as follows:
• Illuminated = traffic detected.
• Extinguished = no traffic detected.
3AES50 AUDIO section (DN9650 only)
Three sets of LEDs provide status information
for the three AES50 audio connectors. The
green OK and red ERROR LEDs per set show
the following:
• Pulsating green with red extinguished =
synchronised and with audio activity.
• Green extinguished with red illuminated =
loss of synchronisation and no audio
activity.
4ASYNCHRONOUS SAMPLE RATE
CONVERTER section (DN9650 only) This
section shows the status of the configured
clock source, which can be AES50 output,
ASRC or network output. Each source has a
yellow ENABLED LED, which illuminates to
show that the source is enabled. The DN9650
also has the facility to stop the output clock if
the input clock fails. This condition is indicated
by the illumination of the red STOPPED LED.
For the LED status, see Table 1 “DN9650 ASRC
LED status” on page 13.
