Upgrading AVM-3901-B, -C, -B4, and -C4
Firmware
Firmware upgrading is a routine procedure that you must perform to
install newer versions of software on the AVM-3901-B, -C, -B4, and
-C4 modules. Pilot, Co-Pilot, or Navigator software applications are
required for this procedure. You can use either the Discovery or the
drag-and-drop method. When performing the upgrading 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.
If for some reason the upgrade fails, the module may not respond to
controls and will appear to be non-functional. In that event, follow the
procedures described in “Correcting a Failed Upgrading Procedure” on
page 19.

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.

When using the AVM-3901-B, -C, -B4, and -C4 module, observe the
Note
If you do not observe these
“Operational Notes,” you may
accidentally change your
parameter settings.
following operational notes:
• If you change parameters within 16 seconds after the
AVM-3901-B, -C, -B4, or -C4 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 you set the FctryRcl (factory recall) parameter to Ye s , the
module takes several seconds to reset all of the parameters. (Setup
parameters are not affected by this factory recall mode.) The lists of
“Operator and All List Parameters” on page 32 and “Tree View
Parameters” on page 57 indicate parameter default settings that are
restored when FctryRcl is set to Ye s .

AES4 Sum AVM-3901-B4 and -C4
However, if you select Non-PCM for one of the AESxFormat
parameters, its summation (AESxSum) is not a valid selection. For
example, if you set AES2Format to Non-PCM, AES2Sum is not a valid
selection. The handling of this selection is described on page 27.
Chapter 3: Operation
PCM Processing
In PCM processing, if you select AES1 Sum, AES2 Sum, AES3 Sum,
or AES4 Sum as the source, the result is the sum of the two parts of the
AES channel, divided by two. (AES3 Sum and AES4 Sum are available
only on the AVM-3901-B4 and -C4 modules.)
For example:
AES1 Sum = (AES1a + AES1b) ÷ 2
Thus, a stereo pair is averaged out, creating a mono signal.
See Figure 3-1 for an illustration of this process.

more information on Setup items, including descriptions and operation
notes.
AVM-3901-B, -C, -B4, and -C4 Installation and Operation Manual 39
Chapter 3: Operation
Alarms
AVM-3901-B, -C, -B4, and -C4 modules provide a default list of eleven
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.
If the AVM-3901-B, -C, -B4, and -C4 modules are 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.

Enabling or Disabling an Alarm Parameter
To enable or disable an alarm parameter, follow these steps:
1. Select Alarms, then select Config, and then press Enter.
2. Select one of the alarm parameters, and then press Enter.
3. Press Enabled or Disabled.
4. Press Enter to activate the selection.
Restoring Default Settings
To restore the alarms to their default settings, follow these steps:
1. Select Alarms, select Config, and then press Enter.
2. Scroll down the list of alarms, and then select Reset.
3. Press Enter to activate the selection.
Chapter 3: Operation
The following table lists the default alarms for the AVM-3901-B, -C,

State Recovery Parameter Availability
The parameter settings for this module are automatically saved onto the
3901RES-E resource module installed in your NEO frame every five
minutes. If a module should fail and be replaced with a cold spare, the
state parameters can be automatically recovered. For more information
on this feature, see the NEO FR-3901, FR-3903, and FR-3923

Tree-View Navigation
The Tree View is one of the three navigation modes available on the
AVM-3901-B, -C, -B4, and -C4 modules. Unlike the other navigation
modes, the Tree View is a multi-level list of parameters, arranged in the
following main groups:
• “Input” on page 57
• “Other” on page 58
• “Output” on page 58
• “Processing” on page 59
• “Setup” on page 59
(See page 39 for more information on the Setup parameters which
govern the operation of the card-edge controls.)
This appendix consists of instructions for navigating the lists (see
page 56) and the Tree View Parameter list.

Overview
Appendix B
Audio Embedding
The audio embedder component in AVM-3901-B, -C, -B4, and -C4
modules is composed of several smaller subcomponent blocks:
• One ancillary data stripper (ADS)
• Four audio embedding subcomponents
The ancillary data stripper (ADS) allows the user to remove all audio
groups presently in the input SDI stream, prior to embedding. The
audio-embedding subcomponents each have the ability to operate on
only one audio group, either appending or overwriting a predetermined
group onto the SDI stream.
AVM-3901-B, -C, -B4, and -C4 Installation and Operation Manual 61
Appendix B: Audio Embedding
Embedding Errors
During the embedding operation, errors may arise for the following
reasons:
• An attempt is made to append a group when it is already present.
• An attempt is made to overwrite a group when it is not present.
• An attempt is made to overwrite a group composed of 20-bit audio
samples with a group composed of 24-bit audio samples.
• There is an overflow condition in the ancillary data space.
• There is an overflow or underflow of the internal buffer.
Preventing Embedding Errors
To avoid embedding errors, follow these guidelines:
• Set the embedding mode to Auto. If the group is present, it will be
overwritten; if it is not present, it will be appended. The overwrite
and append errors are actually warnings that the desired operation is
not being performed.
• Don’t overwrite embedded groups of 20-bit audio samples with
groups of 24-bit audio samples. The required extended data packet
information appended to that group may overwrite a pre-existing
audio group. For 24-bit audio embedding, use the ADS Clean
feature provided.
Use the ADS Clean feature to avoid ADS overflow situations.
