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
Page 13
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.

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.

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 distribu
tion without degrading the signal.
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.

8937 in
Figure 7. The front LED indicators for the 8937D module has an
additional row of identical LEDs labeled for DA 1 and DA 2 as shown in
Figure 8. Upon power-up, the green PWR LED should light and the yellow
CONF LED should illuminate for a few seconds for the duration of module
initialization.
Note When a module is first plugged into a frame, the 8900NET module (if present)
may report a momentary fault. This will clear once the module has booted up.

Remote Configuration and Monitoring
8937/8937D configuration and monitoring can be performed using a web
browser GUI interface or a networked Newton Control Panel when the
8900NET (Net Card) Network Interface module is present in the video
frame (Gecko 8900TFN-V frame). Each of these interfaces are described
below.
Note For remote access, make sure the jumper block on the module is set for both
Local and Remote access (Figure 9 on page 22 and Figure 10 on page 23).
8900NET Module Information
Refer to the 8900NET (Net Card) Network Interface Module Instruction Manual
for information on the 8900NET Network Interface module and setting up
and operating the Gecko 8900 frame network.
Note The 8900NET module in the frame must be running software version 4.2.0 or
higher for proper remote control panel operation. Upgrade software and
instructions for the 8900NET can be downloaded from the Grass Valley ftp
site at ftp://ftp.thomsongrassvalley.com/modular/8900net.
Newton Control Panel Configuration
A Newton Control Panel (hard or soft version) can be interfaced to the
Gecko 8900 Series frame over the local network. Refer to the documentation
that accompanies the Newton Modular Control System for installation,
configuration, and operation information.
Control panel access offers the following considerations for module configuration and monitoring:
• Ability to separate system level tasks from operation ones, minimizing
the potential for on-air mistakes.
• Ability to group modular products—regardless of their physical locations—into logical groups (channels) that you can easily manipulate
with user-configured knobs.
• Update software for applicable modules and assign frame and panel IP
addresses with the NetConfig Networking application.
• Recommended for real-time control of module configuration parameters, providing the fastest response time.
Note Not all module functions are available with the control panel, such as factory
default recalls. The available control panel controls for the module are listed
in Table 4 on page 21.

Configuration
An example of the Newton Configurator is shown in Figure 11.
Figure 11. Newton Configurator Example
Web Browser Interface
The web browser interface provides a graphical representation of module
configuration and monitoring.
Use of the web interface offers the following considerations:
• Provides complete access to all module status and configuration func-
tions, including naming of inputs and outputs, factory parameter and
name default recalls, E-MEM functions, slot configuration, and SNMP
monitoring controls.
• Web access will require some normal network time delays for pro-
cessing of information.
• Configuration parameter changes may require pressing
Enter, upload processing time, and a manual screen refresh to become
effective.
• Web interface recommended for setting up module signal and slot
names, E-MEMs, and reporting status for SNMP and monitoring.
Refer to the Frame Status page shown in Figure 12 on page 26. The 8900
modules can be addressed by clicking either on a specific module icon in
the frame status display or on a module name or slot number in the link list
on the left.

Slot Memory
When the Restore upon Install checkbox on any media module Slot Config
web page has been selected, the current configuration from that module is
saved in slot memory on the 8900NET module. This allows the current
module to be removed and when another module of the same part number,
and software version is installed, the configuration saved to the 8900NET
module will be downloaded to the installed module. The
checkbox must be selected before the current module with the saved configuration is removed.
Note Make sure all modules of the same model type are running the same software
version and have the same part number silk-screened on the printed circuit
board. Downloading a configuration to a module with a different software
version or part number can produce unexpected results.
If a different type of module is installed in this slot, a warning message will
state that the original module type has been replaced with another module
type. In this case, a

Status Monitoring
There are a number of ways to monitor frame and module status. These
methods are summarized here. For more detailed information, refer to the
8900NET (Net Card) Network Interface Module Instruction Manual and the
8900 Gecko or 8900 GeckoFlex Frame Instruction Manuals.
All modular product documentation is available on-line in PDF format at
this link:
http://www.thomsongrassvalley.com/docs/modular
The main status monitoring methods include the following:
• External frame alarm output on the rear of the 8900 frame with
reporting from the Module Health Bus and other frame status alarm
reports,
• LEDs on the Frame, 8900NET module, and individual frame media
modules,
• Web browser status reporting for each frame component, and
• SNMP traps, captured by Thomson Grass Valley’s NetCentral or
another SNMP Manager Application.
Note SNMP trap information is only available when an SNMP Agent has been
installed and configured.

Page 39
External Frame Alarm
An external Frame Alarm output is available on pins 8 and 9 of the RS-232
connector on the rear of the frame. The Frame Alarm outputs a voltage
level indicating there is an alarm condition on the Module Health Bus or
one of the other frame components reported to the Frame Monitor module
in a Gecko 8900TF or GeckoFlex 8900FF frame or the 8900NET module in
an 8900TFN and GeckoFlex 8900FFN frame.
• The Module Health bus is a separate line on the frame motherboard
that provides a means for older or less capable modules (such as DAs
with no microprocessor) that cannot communicate over the Frame
(serial) bus to report warning and alarm conditions to the external
Frame Alarm. All media modules in the frame report a voltage level to
this line when a warning condition occurs on the module. The specific
warning or module location is not reported, only an indication that an
warning condition has occurred.
• Frame alarm reporting from other frame components can be enabled
and disabled using DIP switches on the Frame Monitor and 8900NET
module. For frames with an 8900NET module, the Frame Alarm
Reporting web page allows configuration of the alarms and warnings
that are reported to this external Frame Health Alarm.
Status Monitoring
LED Reporting
LEDs on the front of media modules, the Frame Monitor or 8900NET modules, and the front covers of the 8900TF/TFN and GeckoFlex FF/FFN
frames indicate status of the frame and the installed power supplies, fans
in the front covers, and module status. (The 8900TX-V/A and GeckoFlex
8900FX frames have no LED indicators on the front cover.)
• LED reporting from the modules in the frame to the 8900NET module
is configurable using the 8900NET LED Reporting web page.
• The Status LEDs for this module are described in Operation Indicator
LEDs on page 18. LEDs for the 8900NET module are described in the
8900NET (Net Card) Network Interface Instruction Manual.

Status Monitoring
Web Browser Interface
SNMP Reporting
The 8900NET module controls a web browser GUI that indicates frame and
module status on the following web pages:
• Frame Status web page – reports overall frame and module status in
colored graphical and text formats. Refer to Figure 12 on page 26 for an
example.
•Module Status web page (Figure 14 on page 29) – shows specific input
and reference signal configuration error status to the module along
with module status and information (part number, serial number, hardware version, software/firmware/boot versions, and Asset number (as
assigned on the Slot Config web page).
• A Status LED icon on each web page reflects the module status on the
module Status web page where warnings and faults are displayed and
is a link to the module Status web page.
The Gecko 8900 Series system uses the Simple Network Monitoring Protocol (SNMP) internet standard for reporting status information to remote
monitoring stations. When SNMP Agent software is installed on the
8900NET module, enabled status reports are sent to an SNMP Manager
such as the Grass Valley’s NetCentral application.
Status reporting for the frame is enabled or disabled with the configuration
DIP switches on the 8900NET module. Most module status reporting items
can be enabled or disabled on individual configuration web pages.

Service
The 8937 and 8937D modules make extensive use of surface-mount technology and programmed parts to achieve compact size and adherence to
demanding technical specifications. Circuit modules should not be ser
-
viced in the field unless directed otherwise by Customer Service.
If your module is not operating correctly, proceed as follows:
• Check frame and module power and signal present LEDs.
• Verify power at the voltage testpoints (see Figure 21) and check fuse if
no voltage is detected.
• Check for presence and quality of input signals.
• Verify that source equipment is operating correctly.
• Check cable connections.
Refer to Figure 7 on page 17 for the location of the PWR LED and Tab le 2
on page 18 for proper LED indications.
If the module is still not operating correctly, replace it with a known good
spare and return the faulty module to a designated Grass Valley repair
depot. Call your Grass Valley representative for depot location.
Refer to the Contacting Grass Valley on page 4 at the front of this document
for the Grass Valley Customer Service Information number.

Functional Description
Input and Output Processing
The input section(s) receive SD (standard definition) video from the rear
input BNCs and send it to signal equalizing and reclocking circuits. The
input section can also bypass reclocking circuits to the output amplifiers.
The output amplifiers drive eight equal-phase outputs on the rear back
plane for the 8937 and one set of four outputs and one set of three outputs
for the 8937D.
Note All outputs are in phase with the input signal.
Microprocessor and Input Selector
The primary purpose of the microprocessor is to provide remote control
and monitoring capability for the module. It receives signal present, signal
lock, and speed detection signals from the equalizer and reclocker circuits.
Using this information, local jumper settings, and remote control com
mands, the microprocessor selects the internal signal path and gives feedback through the LEDs and remote control bus.
Functional Description
-
-
User-enabled video presence detection generates individual SNMP traps
for each channel that can be sent to an SNMP manager via the microprocessor
