This section covers difficulties that may be encountered using a dCS Verdi
SACD Transport (v1.20 or later), a dCS Verdi La Scala Upsampling SACD
Transport or a dCS Purcell Upsampler to drive a dCS Elgar Plus DAC (v4.20 or
later) or Delius DAC (v2.20 or later) with DSD data over an IEEE 1394 interface.

This can happen momentarily during locking. If it does not change to
Active, open the Transport or Upsampler's menu and ensure the
page is set to Active.
"No Comms"

chain are switched on and securely connected by 1394 cables.
"Search.."

This will appear briefly after the 1394 system has established
communications.

both 1394 connectors from one unit to both 1394 connectors on another unit
or set up a loop. This prevents the 1394 bus settling.
•
Check that the 1394 cables are correctly fitted.
•
With the DAC in slave mode, check there is an undamaged BNC cable
connecting Verdi's
•
Ensure the cable is D.C. coupled. A.C. coupled cables are not suitable for
use with Wordclock or SDIF.
•
With the DAC in master mode, check there is an undamaged BNC cable

•
Verdi / La Scala has detected a clock frequency other than 44.1kHz on it's
connector. Ensure the clock source is set to 44.1kHz.
