Troubleshooting the IEEE 1394 Interface
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.
Upsampler or Transport displays “
Inactive
”
•
This can happen momentarily during locking. If it does not change to
Active
, open the Transport or Upsampler’s menu and ensure the
Transmit
page is set to
Active
.
The Unit keeps displaying
“No Comms”
•
This will appear briefly while the 1394 system is checking for connections.
•
If
the
No Comms
message does not clear, ensure that all units in the 1394
chain are switched on and securely connected by 1394 cables.
The Unit keeps displaying
“Search..”
•
This will appear briefly after the 1394 system has established
communications.
•
If
the
Search
message does not clear, ensure that you have not connected
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.
The DAC displays
“Verdi Wordclock Missing”
•
With the DAC in slave mode, check there is an undamaged BNC cable
connecting
Verdi
’s
WClk Out
to the DAC’s
WClk In
.
•
Ensure the cable is D.C. coupled. A.C. coupled cables are not suitable for
use with Wordclock or SDIF.
The DAC displays
“Missing Wordclock between Clk Out & Verdi Clk In”
•
With the DAC in master mode, check there is an undamaged BNC cable
connecting the DAC’s
WClk Out
to
Verdi
’s
WClk In
.
•
Ensure the cable is D.C. coupled. A.C. coupled cables are not suitable for
use with Wordclock or SDIF.
The DAC displays
“Please check source slaved to DAC Wordclock Out”
•
With the DAC in master mode, check there is an undamaged BNC cable
connecting the DAC’s
WClk Out
to the source’s
WClk In
.
•
Ensure the cable is D.C. coupled. A.C. coupled cables are not suitable for
use with Wordclock or SDIF.
The DAC displays
“Wrong Wordclock @ Verdi Clk In”
•
Verdi
/
La Scala
has detected a clock frequency other than 44.1kHz on it’s
WClk In
connector. Ensure the clock source is set to 44.1kHz.
•
With the DAC in master mode, check there is an undamaged BNC cable
connecting
Verdi
/
La Scala
’s
WClk Out
to the DAC’s
WClk In
.
•
Ensure the cable is D.C. coupled. A.C. coupled cables are not suitable for
use with Wordclock or SDIF.
