16 on-air channels. Opus meets multi-channel digital integration challenges for both high-definition and
standard-definition formats.

Integrated Content Environments offer the greatest opportunity for productivity and performance gains when
employing content management and control applications that place content, operations or remote locations under
common software controls.

A major workflow enhancement is Leitch’s Ingest Control Manager

™

, which places control of up to 16 server

channels with associated proc amps (DPS-575), eight VTRs and eight separate routers under one control station.

Upgrading AS-3981-AD Firmware

Firmware upgrading is a routine procedure that you must perform to
install newer versions of software on the AS-3981-AD module. 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 17.

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.

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 Yes , 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 25 and “Tree View
Parameters” on page 47 indicate parameter default settings that are

restored when FctryRcl is set to Ye s .

• Changes in some parameters will cause additional changes in other
parameters, or lock them out entirely. See page 23 for more
information on these cross-functional parameter changes.

notes.

30 AS-3981-AD Installation and Operation Manual

Alarms

AS-3981-AD 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 AS-3981-AD 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.

Each AS-3981-AD module has 12 card-edge LEDs and four module
indicators.

The module generates visible alarm signals to alert users of failures or
impending failures. You will find these alarm signals in the following
locations:

• As red or yellow LEDs on the front module card-edge

• As red or yellow LEDs on the 3901AIC Alarm Interconnect
Module or the 3901RES-E Resource Module (visible via light pipes
through the frame’s front panel)

• As part of a list of activated alarms in the Setup menu

• In external systems connected to the alarm contact closures at the
back of the NEO frames

• On a PC screen where you use Pilot or another GUI-based control
application

Tree View Navigation

The Tree View is one of the three navigation modes available on the
AS-3981-AD module. Unlike the other navigation modes, the
Tree View is a multi-level list of parameters, arranged in the following
main groups:

• “Input” on page 47

• “Other” on page 47

• “Output” on page 47

• “Processing” on page 48

• “Setup” on page 48

(See page 30 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 46) and the Tree View Parameter list.

AS-3981-AD Installation and Operation Manual 45

Appendix A: Tree View Navigation

Navigating the Tree View

To navigate and then view or change a parameter from the Tree View,
follow these steps:

1. Open the front panel of the NEO frame.

2. Press any card-edge control to turn on the VFD display.

Note

If you do not wish to make
changes to your settings, return
to the previously selected item
in the list, and then press

Escape to move up a level. See
SelPar Adj Mode in the Setup

section at the end of the Tree
View to enable or disable this
delayed adjust mode feature.

The message AS-3981-AD will appear as the banner on the
card-edge display.

3. Press the Enter button.

The first two items in the Level One list will appear.

4. Click Nav- (down) on the Nav-/Nav+ switch to view more items in
the Level One list.

5. Select the desired item in the Level One list, and then press Enter.

This leads you to the Level Two list.

Note

After several seconds of
inactivity, a scrolling message
will appear, describing the
purpose of the currently selected
parameter.

6. Repeat steps 3 and 4 to view more items in Levels Two, Three, and
Four.

7. If the parameter is selectable, slide the bar to the desired parameter
using the Nav+/Nav-switch.

OR

Select the desired item in the Level Four list, and then press Enter.

Once the Level Four parameter is set or viewed, you can leave the
parameter in its current state, or return to the banner. To return to the
AS-3981-AD banner, repeatedly press the Escape button.

Close the front panel again after you have completed the procedure to
prevent the frame from overheating.
