Chapter 2: Installation and Removal
Correcting a Failed Upgrading Procedure
Firmware upgrades may fail in the event of network interruptions,
power failures, or if too much data is uploaded to the NEO module.
Often, uploads of too much data can occur for one of the following
reasons:
• The boot file (typically vxWorks.lzs) was accidentally uploaded
during the fl0 procedure, instead of the boot procedure.
• Files were sent to the wrong NEO module.
• The particular hardware version of the module requires only some
(but not all) of the available fl0 files.
• The upgrade .zip file was mistakenly sent to the module.
All of these problems can be corrected by re-installing the firmware
while in a fail-safe mode, as described in the following pages. When
you are performing this procedure, check the appropriate readme file to
confirm which files are needed. Use care to ensure that you upload the
correct files to the intended module.
Setting the Module to Fail-Safe Loader Mode
Follow these steps to set a NEO module to the fail-safe loader mode:
1. Remove the affected module from the NEO frame.
2. Press the Nav switch down while simultaneously pressing both the
Escape and Enter buttons.
3. While still pressing the buttons and the navigation switch, reinsert
the module into the frame and hold for approximately three seconds
until the display on the module reads Offline-H (or Offline-L)
Upload Required.
Upgrading the Firmware in Fail-Safe Mode
Follow these steps to upgrade the firmware in the fail-safe mode:
Note
To successfully upgrade the
firmware, you must follow these
steps in the exact sequence
described.
1. Download the most recent appropriate upgrade package from the
Leitch Web site or from your CD-ROM, and then unzip the upgrade
package.

Operation Notes
When using the ADC-3981 module, observe the following operation
Caution
notes:
If you do not observe these
“Operation Notes”, you may
accidentally change your
parameter settings.
• If you change parameters within 16 seconds after the ADC-3981
banner first appears on the VFD, your changes will not be saved.
Parameter changes that you make after this 16-second delay will be
saved and restored if the module loses power and must be restarted.
• Although the effect of a parameter change may appear to be
immediate, the module requires 20 seconds to save the latest
change. If another change is made during these 20 seconds, the first
parameter change and the second parameter change will not be
saved until 20 seconds after the second parameter change. There is
no limit to the number of changes that can be made within 20
seconds of each other. However, none of these changes will be
saved until 20 seconds after the last parameter change.
• When the FctryRcl (factory recall) parameter is set to Ye s, the
module takes several seconds to reset all of the parameters. (See
the “Operator and All List Parameters” on page 23 or the “Tree
View Parameters” on page 39 to view the factory recall default
settings.) Setup parameters are not affected by the factory recall
mode.
• Changes in some parameters will cause additional changes in other
parameters, or lock them out entirely. See page 21 for more
information on these cross-functional parameter changes.

more information on Setup items, including descriptions and operation
notes.
26 ADC-3981 Installation and Operation Manual
Alarms
ADC-3981 modules provide a default list of four alarms. You can
disable any alarm by modifying the Alarms parameter in the Setup
section.
When you select Alarms, all of the active alarms are visible in the
display, below Config (Configurations). If no alarms are active, only
Config appears.
Alarm Synchronization
Alarm synchronization is available for this module if your NEO frame
contains a 3901RES-E resource module that supports the feature. When
active, alarm synchronization ensures that the alarm configuration
settings of card-edge controls and the CCS control software and control
panels are consistent.
Chapter 3: Operation
If the ADC-3981 module is set for local control, the alarm settings will
appear the same at both the card edge and via CCS, but the settings can
only be changed using the card-edge controls. If the module is set for
remote control, the alarm settings can be changed via both the card edge
and CCS control software and control panels.
Alarm configuration settings undergo DejaView (state recovery)
automatically. This means that when a module is hot-swapped, the
alarm configuration for the new module is updated to the settings of the
module that was previously in that slot. See “State Recovery Parameter
Availability” in this chapter for more information.
Identifying the Cause of an Alarm
To identify the reason for an alarm, select the active alarm, and then
press Enter. A scrolling message appears on the VFD describing the
cause of the fault.
