B. Programming Error
If an error occurs during the programming step, the
consequences will depend on the type of update:
- SOFTWARE UPDATE: The Application Software is probably corrupted but the
Loader is intact and can be used to restore the DCD-24 (see 14.5).
- COMPLETE UPDATE: A Programming error during a 'complete' update is most
likely not recoverable via Ethernet and your DCD-24 will need to be returned to
the factory for a full restore of its flash memory.
IMPORTANT:
IF A PROGRAMMING ERROR OCCURED DURING A 'COMPLETE'
UPDATE AND THE UNIT IS STILL ON, TRY RUNNING THE PROGRAM-
MING SEQUENCE AGAIN AS DESCRIBED IN 14.2, WITHOUT CYCLING
POWER.
IF POWER IS TURNED OFF, THE UNIT WILL MOST LIKELY NEED TO BE
RETURNED TO THE FACTORY.
14.5 LOADER
The Loader is a fall-back web page that allows you to restore your DCD-24 in case
of programming failure. This page is located in a different area of the Flash Memo-
ry (see LOADER SOFTWARE on the Flash Memory map above, 14.2).
To enter the LOADER mode:
Hold down the [
] and [
] keys while powering up and until "DCD-24"
down
setup
appears on the display (you don't have to hold down the power key itself -- a single
hit is sufficient).
The unit will next display "Loader" instead of the usual software version number.
From Loader mode the IP addresses and DHCP mode can be adjusted in the usual
way. Then, simply point your browser to the IP address of your DCD-24.
The LOADER page is similar to the regular Upload page described above, without
active status updates.
To restore your unit, use the BROWSE button to locate the firmware file on your
hard disk (.upld) and click UPLOAD. The normal programming sequence described
in 14.3 will follow. Either "software" or "complete" files can be uploaded this way.

Through WC outputs 9-12, the DCD-24 can apply a multiplier or a divider to the
selected base frequency. Here is a list of the available rates. An 'X' indicates this
choice is not available.
