Preface

8 8937/8937D — Instruction Manual

8937 and 8937D SDI/ASI Reclocking EQ SNMP DAs

Introduction

The 8937 module is a 1 x 8 looping input, auto-reclocking, auto-cable equal­izing DA with SNMP monitoring capability. The module is suited for
medium to long distance signal distribution.

The 8937D (dual) module provides two separate SDI distribution ampli­fiers on a single card. It also has auto-reclocking, auto-cable equalizing with
SNMP monitoring capability for both video channels. The module is ideal
for environments where compact and high density capability is required
such as mobile trucks.

The 8937 and 8937D feature:

• Jumper selectable Bypass/270Mb/Reclock mode with auto bypass,

• Auto detection and front panel indication of all SMPTE 259M signal
data rates,

• Auto, Manual, or Bypass mode for input bit rate standard selection,

• Auto cable equalization for up to 300 meters of cable for SDI SMPTE
signals up to 270 Mb/s and 200 meters for 360 Mb/s,

• Suitable for SMPTE 259M, DVB-ASI, SDI 270 Mb/s and other 800 mV
data ranging from 50 Mb/s to 360 Mb/s with maximum P/N of 19/1,

• Signal presence indication with module specific SNMP trap generation,
and

• Remote health monitoring interface.

This manual covers installation, configuration, and operation for both the
8937 and 8937D modules.

Installation

Installation

Gecko 8900 Frame

The 8937 and 8937D modules can be installed in either an 8900 Gecko or
GeckoFlex frame. An 8900V-R rear module is required for use in the
GeckoFlex frame.

Installation of an 8937 module in an 8900 Gecko frame is a process of:

1. Placing the module in the proper frame slot,

2. Setting jumper settings if using local configuration controls (see Local

On-Board Configuration on page 22), and

3. Cabling signal ports.

The 8937 module can be plugged in and removed from an 8900 Series Video
frame with power on. When power is applied to the module, LED indica­tors reflect the initialization process (see Power Up on page 17).

Frame Capacity

The 8937 and 8937D modules can be installed in all Gecko 8900 Series Video
but with varying maximum quantities determined by frame cooling
capacity.
maximum module count for each frame type.

The third slot from the right is allocated for either a Frame Monitor Module
or a 8900NET (Net Card) Network Interface Module. For additional infor
mation concerning the controller module options, refer to the 8900NET (Net

Card) Network Interface Module Instruction Manual.

Figure 1. 8900 Series Video Frame Slots

-

8900 module slots are interchangeable within the frame. There are 10 BNCs
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 a Gecko 8900 video frame can accept is ten.

Figure 2 illustrates the rear connector plate for a Gecko 8900 video frame.

Figure 2. Gecko 8900 Series Video 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.

8937/8937D — Instruction Manual 11

3. Press in the ejector tab to seat the module.

Installation

GeckoFlex Frame

Installation of the 8937 and 8937D module in a GeckoFlex frame is a process
of:

1. Installing the 8900V-R rear module into the rear of the frame,

2. Setting local jumper settings if configuring the module with on-board

controls,

3. Placing the 8937 module in the corresponding front frame slot, and

4. Cabling and terminating signal ports.

Module Installation Precautions

Please read and follow the precautions listed below before installing the
front and rear modules:

• 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).

• 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 (751­version frames only). For 650- version frames without the tool, use a
2 mm (5/64”) hex screwdriver. Please do not use an electric screw­driver.

• 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 rear retainer screw torque specification under

Mechanical in Tab le 7 on pa ge 41.

12 8937/8937D — Instruction Manual

Rear Module Installation

Use needlenose pliers
to pull out blank after
removing retainers.

To install a rear module into the frame, follow these steps:

Note Please read Module Installation Precautions on page 12 before installing the

rear module.

1. Each 8900V-R rear module or blank rear adapter cover is held in place

by two retainer clips as shown in Figure 3. Loosen (but do not remove
completely) the two screws holding each retainer clip to the frame with
a 2 mm (5/64”) hex screwdriver. Pull up on the retainer to remove it,
leaving the screws in place.

CAUTION Be careful to leave the screws in place as they can be easily lost or fall into

equipment below the frame creating a shorting hazard.

2. Remove the blank rear adapter cover by inserting needlenose pliers

into the slots in the top and bottom of the blank and pulling it off.

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.

Installation

3. Insert the rear module into the empty slot.

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

module and push down to seat the retainer.

5. Tighten the screws for each retainer clip just until they are snug. Do not

force or torque the screws too tightly. The retainer screw torque
specification is 4-5 inch-lb/0.45-0.6Nm.

Installation

Front Module Installation

After installing the rear module, install the front module as follows:

Note If configuring the module using local on-board jumpers, set the jumpers

according to the instructions in Local On-Board Configuration on page 22
before installing the front module.

1. Remove the front cover of the frame.

2. Locate the corresponding front slot.

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 4).

4. Carefully slide the module into the rear connector.

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

6. Reinstall the front cover of the frame during normal operation.

Installation

Refer to Figure 5 for cabling the 8937 module. Cabling to and from the
module is done at the back of the Gecko 8900 video frame or on the corre­sponding 89000V-R rear module of the GeckoFlex frame as described
below.

Loop-Through Input

One serial digital component input is provided at differential loop-through
BNCs J9 and J10. If the unused input is not looped to another device, it
should be terminated in 75 ohm.

Outputs

There are eight outputs for the 8937 module at BNCs J1 through J8. Output
destination equipment should have an input impedance of 75 ohm unless
it has loop-through inputs, in which case the loop-through inputs must be
terminated into 75 ohm. All outputs are in phase with the input signal.
