Preface

8 8925DMB-B and -U — Instruction Manual

8925DMB-B and -U HD/SD Digital Audio De-Embedder

Introduction

The 8925DMB module is available in two versions: the 8925DMB-B with
balanced audio outputs using the 8900BVF-R rear module and the
8925DMB-U with unbalanced audio outputs 8900UVF-R rear module. The
8925DMB-B and 8925DMB-U modules perform the action to de-embed
(demultiplex) up to four AES audio streams out of a HD/SD SDI signal.

The two models 8925DMB-B and 8925DMB-U must be installed in a
GeckoFlex frame (8900FFN). Configuration of the 8925 module requires the
presence of an 8900NET module with software version 4.3.0 or later
installed in the GeckoFlex frame as there are no local on-board controls for
configuration.

Module Features

The 8925DMB-B and 8925DMB-U module features include:

• One multi-format HD/SD video input and three HD/SD video outputs

• One reclocked loop through video output,

• Up to four audio outputs balanced (with 8900BVF-R rear module) or

• A fiber optic submodule option can be installed to provide optical

• Remote control and monitoring support including web pages, Newton

Module Placement in the GeckoFlex Frame

The front and the rear modules are delivered together as a set. Two choices

are available: one for balanced audio outputs with the 8900BVF-R rear

module and one for unbalanced audio outputs with the 8900UVF-R rear

module.

The 8925DMB front module can be plugged in and removed from a

GeckoFlex frame with power on, without disrupting operation on adjacent

running modules. When power is applied to the module, LED indicators

reflect the initialization process (see

There are ten rear and front slot locations in the 2 RU frame to accommodate

either audio or video modules (

plugged into any one of the available GeckoFlex frame slots. The 8925DMB

requires a single rear slot.

Power Up on page 19).

Note Use anti-static precautions when handling the module. As the module can be

changed when the GeckoFlex is powered on, before removing the cover,
please put an anti-static bracelet tied to a metal part of the frame.

Module Installation Precautions

Please read and follow the precautions listed below before installing the
front and rear modules and any fiber optic option submodule (8925DMB
models only):

• Use standard anti-static procedures during installation. As modules
can be installed or removed when the GeckoFlex frame is powered up,
before removing the cover, please use an anti-static bracelet tied to a
metal part of the frame.

• Install the rear module first, then the front module, then the optical sub­module option if used on the 8925DMB.

• When installing or removing a rear module, loosen or tighten the
screws holding the retainer clips to the frame manually with the
retainer clip tool provided inside the front cover of the frame or use a
2 mm (5/64”) hex screwdriver. Please do not use an electric screw­driver.

Note On newer 751- version GeckoFlex frames, a Rear Retainer Clip removal tool

and 2 extra retainer clips and screws for installing them are provided on the
inside of the frame cover.

Installation

• Make every effort to leave the screws holding the retainer clips in place
(do not remove them completely). They are very small and can easily
drop into other equipment causing a shorting hazard. (Two turns of the
screw should be enough to loosen the screws, 3 turns or more will
remove it.)

• When installing a rear module, tighten the screws on the retainer clips
just until snug. Do not apply more force than is necessary to seat the
rear module. Refer to the

page 48.

• If using a fiber optic submodule on the 8925DMB fiber ready module,
handle it carefully, use anti-static precautions, and read the Fiber Optic

Cleaning Requirement on page 15 before cabling.

Mechanical specifications given in Tab le 5 on

8925DMB-B and -U — Instruction Manual 11

Installation

Rear Module Installation

1. To remove a blank rear adapter cover (or a rear module already

present), manually loosen the two screws holding each retainer clip on
the rear adapter cover or rear module to the frame with the retainer clip
tool provided inside the front cover of the frame (751- model frames
only) or a 2 mm (5/64”) hex screwdriver.

Note To remove a rear module already installed, follow the same steps. It is helpful

to first remove the front module so the rear can be pulled out more easily.

1. After loosening the retainer clip screws, pull up on each retainer and

completely remove it, leaving the screws in place.

2. Remove the blank rear adapter cover by inserting the retainer clip tool

or needlenose pliers into the slots in the blank cover and pulling it off
(Figure 2).

3. Insert the rear module into the empty slot, guiding it carefully into

place.

4. Replace each retainer clip over the two screws on both sides of the

module and push down to seat the retainer clip.

5. Tighten the two screws on each retainer clip just until they come into

contract with the retainer clip then tighten about a 1/4 turn more
(maximum torque is 4-5 inch-lb/0.45-0.6Nm). Do not force or torque
the screws too tightly. The clips should not bend or be bowed.

Note All unused rear slots in a GeckoFlex frame should have a blank rear adapter

cover installed.

Installing Front Module

After installing the rear module and configuring the front module using
local controls if required, install the front module as follows:

1. Remove the front cover of the frame.

2. Locate the front slot corresponding to the rear module you have already

installed.

3. Insert the front module so that the plastic card guides on the module

top and bottom edges go over the upper and lower raised rail guides on
the right of the top and bottom of the slot (Figure 3).

4. Carefully slide the module into the rear connector, making sure the

fiber optic connector on the 8925DMB module fits into the rear module
properly.

5. Lock the front module ejector tab into the locking pin.

6. Replace the frame front cover during operation to maintain optimum

cooling conditions.

Installation

Fiber Optic Cleaning Requirement

Before making any fiber optic cable mating connections, including installa­tion, and after every de-mating cycle, use an industry standard fiber optic
cleaning kit, including oil-free compressed air, to clean the fiber connectors
and the connectorized fiber end faces. This helps ensure optimum perfor
mance of the fiber optic interface. Industry standard fiber optic cleaning
kits can be purchased on the web and in electronics stores.

To install the fiber optic submodule:

1. Slide the fiber optic submodule into the cage connector connected to the

front module at the rear of the frame (label on right).

2. When installed properly, the front end of the submodule will line up

with the rear module BNCs. Do not try to force it in further.

3. Cable the fiber optic connectors according to the instructions given in

Cabling on page 17 depending on the type of submodule used.

To extract the fiber optic submodule follow the steps below:

1. Remove the fiber cable first.

2. Unlock the module by flipping the handle to the left.

3. Remove the fiber optic submodule by using its handle.

Cabling

Cabling

Cabling to the 8925DMB-B or 8925DMB-U module is done on the
8900BVF-R rear module (balanced audio inputs) or the 8900UVF-R rear
module (unbalanced audio inputs).

The I/O Config web page shows the inputs and the outputs assigned to the
different connectors of the rear modules. Cabling of the rear module
depends on what fiber optic submodule option is installed as below:

• 8925DMB-B and 8925DMB-U without fiber optic submodule option
(electrical only),

• 8925DMB-B and 8925DMB-U with SFP-13103G-M1DRX (Dual Receiver
Fiber Optic)

• 8925DMB-B and 8925DMB-U with SFP-13103G-M1DTX (Dual Trans­mitter Fiber Optic), and

• 8925DMB-B and 8925DMB-U with SFP-13103G-M1TRX (Transceiver
Fiber Optic).

The 8925DMB-B and the 8925DMB-U will accept any of the video stan­dards listed in the input specifications in Tab le 5 on page 48.

Ta bl e 2 below gives the inputs and the possible video output connections

for the 8925DMB rear modules. The cabling is illustrated in Figure 5 on

page 18 for the 8900VBF-R rear module and Figure 6 on page 18 for the

8900UVF-R rear module.
