8937 and 8937D 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. 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/reclock mode with auto bypass,

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

•Auto format detection (525/625),

•Auto cable equalization for up to 300 meters of cable with front panel
EQ warning,

• Suitable for SMPTE 310M, SMPTE 259M, DVB-ASI, SDI 270 Mb/s and
other 800 mV data ranging from 4 Mb/s to 360 Mb/s,

• Signal presence indication with selectable SNMP trap generation, and

•Remote health monitoring interface.

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

Installation of a module is a process of:

The module can be plugged in and removed from a Gecko 8900 video
frame with power on. When power is applied to the module, LED indica­tors reflect the initialization process (see

The 8937 and 8937D module can be installed in all Gecko 8900 video 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.

Module Placement in the Gecko 8900 Frame

There are ten cell locations in the video frame to accommodate modules.
These are the left ten locations. Refer to Figure 1.

The two cells on the right are allocated for the power supplies. For addi­tional information concerning the Power Supply module, refer to the 8900
Power Supply manual.

The third cell from the right is allocated for the Frame Monitor or 8900NET
Network Interface module. These modules provide health monitoring and
control options.

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.

To install a module in the frame:

Insert the module, connector end first, with the component side of the
module facing to the right and the ejector tab to the top.

Verify that the module connector seats properly against the backplane.

Press in the ejector tab to seat the module.

Installation

Module On-board Jumper Settings

8937 Module

Two on-board jumpers must be set on the 8937 module to determine
module formatting before installing it in the frame. Refer to Figure 3 for
jumper locations on the module circuit board.

•DA 1 Bypass – set jumper J6 for AUTO (pins 1-2) to enable auto

• Local/Remote – set jumper J7 to LOCAL (pins 1-2) to lock out remote

reclocking (for signal data rates of 143, 177, 270, and 360 Mb/s) or
BYPASS (pins 2-3) to bypass reclocking (for signals with data rates of
4 Mb/s to 360 Mb/s). This setting can be overridden by remote con­trols.

8937D Module

Three on-board jumpers must be set on the 8937D module to determine
module formatting before installing it in the frame. Refer to Figure 4 for
jumper locations on the module circuit board.

•DA 1 BYPASS/AUTO – for DA 1, set jumper J6 for AUTO (pins 1-2) to
enable auto reclocking (for signal data rates of 143, 177, 270, and
360 Mb/s) or BYPASS (pins 2-3) to bypass reclocking (for signals with
data rates of 4 Mb/s to 360 Mb/s). This setting can be overridden by
remote controls.

•DA 2 BYPASS/AUTO – for DA 2, set jumper J5 for AUTO (pins 1-2) to
enable auto reclocking (for signal data rates of 143, 177, 270, and
360 Mb/s) or BYPASS (pins 2-3) to bypass reclocking (for signals with
data rates of 4 Mb/s to 360 Mb/s). This setting can be overridden by
remote controls.

• Local/Remote – set jumper J7 to LOCAL (pins 1-2) to lock out remote
control or LOCAL & REMOTE (pins 2-3) for access to remote control.
This setting cannot be overridden by remote controls.

Looping Capabilities

The reclocked output signal from one 8937 or 8937D module may be looped
to up to ten reclocked 8937 or 8937D modules in series for further distribu­tion without degrading the signal.

8270_06

The output signal from modules operating in Bypass mode (not reclocked
to one of the standard rates) will begin to degrade by the third module in
the series. This looping is not recommended.

Installation

Cabling

8937 Module

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 as described
below.

Note

At the back of every manual are two sets of printed overlay cards that can be
placed over the rear connector BNCs to identify the specific connector func­tions.

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

Ω

.

Outputs

There are eight outputs for the 8937 module at BNCs J1 through J8. Output
destination equipment should have an input impedance of 75
