Preface
About This Manual
This manual describes the features of a specific module of the Gecko 8900
Signal Processing System. As part of this module family, it is subject to
Safety and Regulatory Compliance described in the Gecko 8900 Series
frame and power supply documentation (see the 8900TX/8900TF/8900TFN
Frames Instruction Manual ).

8920MUX Video/Audio
Multiplexer
Introduction
The 8920MUX is a single format Serial Digital (SD) Video/AES3 multi-
plexer that inserts AES/EBU audio into the ancillary data space of
SD 270 Mbit component 525 or 625 digital video. An audio group contains
up to two AES/EBU audio streams. Each audio group in the SD input
signal (up to four groups total) is packaged with a unique identification
(ID). The 8920MUX uses this ID to insert, replace, or delete any one of the
existing groups. The module can also delete all ancillary data contained in
the SD input signal.
The 8920MUX:
•Is a hot-swappable module (can be removed and replaced in the frame
with power on),
• Stores settings in non-volatile memory (if the power to the module is
cycled, the module will maintain its settings),
•Multiplexes up to two AES/EBU audio digital streams,
•Requires 48 kHz AES/EBU streams synchronous or asynchronous
(minimum grade 2 compliant AES audio within ± 50 ppm of the 48 kHz
sample rate) with input SD video,
•Supports Grass Valley Modular Remote Configuration and Monitoring
web browser and Newton Control Panel (with 8900NET module
running software version 3.2.0 or later),
• Supports EDH (error detection and handling) error reporting system
for the video and audio signal,
•Can delete incoming audio groups,
•Can select one of four audio groups to replace or delete, and
•Provides a status display of incoming and inserted/replaced audio
groups.

Software Requirements
Software Requirements
Operation of 8920MUX modules with version 4.2.0 software or later require
an 8900NET module running version 3.2.0 or later software. To upgrade
your 8900NET module, go to the Grass Valley web site or contact Customer
Service. See Contacting Grass Valley on page 2 for contact information.
Installation
Installation of the 8920MUX module is a process of:
1.
Setting on-board jumpers to determine audio input type (110
Ω
balanced or 75
Ω unbalanced) and remote control lockout,
2.
Placing the module in the proper frame slot, and
3.
Cabling and terminating signal ports.
The 8920MUX module can be plugged in and removed from an 8900 Series
frame with power on. When power is applied to the module, LED indica-
tors reflect the initialization process (see Power Up on page 12).
Setting On-Board Jumpers
Jumpers on the 8920MUX module must be set for remote or local control
and for the audio input type with the following on-board jumpers shown
in Figure 1 on page 9:
• Jumper JP10 sets control mode for Local only or Remote and Local.
When a jumper is placed across pins 2 and 3 of jumper block JP10,
module output mode settings are adjustable from the Local on-board
switches only. To have both Local and Remote access, set the jumper
across pins 1 and 2.
• Jumpers JP1, JP5, JP7, and JP8 select either 75
Ω unbalanced or 110 Ω
balanced AES/EBU inputs. All four jumpers must be set for the correct
input type.

Frame Capacity
The 8920MUX module can be installed in all 8900 Series frames but with
varying maximum quantities determined by frame cooling capacity.
Table 1 provides the power capacity, cooling capacity, and maximum
module count for each frame type.
Note Module capacity figures assume no other modules are in the frame.
Module Placement in the 8900 Frame
There are ten slot locations in the frame to accommodate either analog or
digital modules. These are the left ten locations. Refer to Figure 2.
The two slots on the right are allocated for the power supplies. For addi-
tional information concerning the Power Supply module, refer to the 8900
Frame manual.
The third slot from the right is allocated for the Frame Monitor, or 8900NET
Network Interface module. These modules provide health monitoring and
control options.

Installation
Figure 2. 8900 Series Frame
8900 modules are interchangeable within the module slots. There are 10
BNC connectors in each slot’s I/O group. The functional assignment of
each connector in a group is determined by the module that is placed in
that slot. The maximum number of modules an 8900 frame can accept is
ten. Figure 3 illustrates the rear connector plate for an 8900 Series frame.
Figure 3. 8900 Series Frame Rear Connector
To install a module in the frame:
1.
Insert the module, connector end first, with the component side of the
module facing to the right and the ejector tab to the top.
2.
Verify that the module connector seats properly against the backplane.
3.
Press the ejector tab in to seat the module in place.
