MODULE OVERVIEW
The 5120 Dual Serial DA is a two-channel digital video distribution amplifier with four
outputs per channel. The 5125 is also a two-channel digital video distribution amplifier
that provides reclocking of the serial data stream, improving jitter performance. The two
output channels on each module provide distribution of a serial digital input signal to four
outputs with automatic input equalization.
Up to 300 meters of cable can be equalized locally on each module. Maximum cable length
can also be set and other module status parameters monitored remotely using the optional
Avenue Touch Screen Control Panel and the Avenue PC Control Application.
As shown in the block diagram below, each input signal passes through a serial equalizer
circuit. The signal strength of the equalized output is monitored by the module processor
for cable equalization and EQ warning information available to the user via the front
panel control indicator or through the optional Avenue control interfaces. The video in the
5125 passes through reclocking circuitry. The serial outputs are buffered then AC coupled
to the BNCs on the rear of the frame providing eight serial outputs for distribution.
Power is derived from the ± 12 volt frame power. It is regulated to the required +5 volts
for the module by on-board regulator. The module is fused with a resettable fuse device. If
the fuse opens due to an overcurrent condition, the module will lose power. After pulling
the module, the fuse will reset automatically requiring no replacement fuse.
Module ID information (slot location, software version and board revision) can be
monitored by the optional frame System Control module and read using the optional
interfaces available.

APPLICATIONS
The 5120 and 5125 Dual Serial DA modules can be utilized in distribution applications
where a modest number of DAs are required. The two channel capability can save rack
space and cost.
5120 Dual Serial DA
The 5120 Dual Serial Distribution Amplifier is a two-channel non-processing DA with
cable equalization and signal detection. In the example below, the serial digital PGM and
PVW outputs of a digital switcher are distributed throughout a facility from the 5120 DA.
One PGM and PVW output is fed to a 5250 DAC for viewing the outputs on analog
monitors.
5125 Reclocking Dual Serial DA
The 5125 Reclocking Dual Serial Distribution Amplifier can be used in similar distribution applications where reclocking is required to reduce jitter from long cable runs or
unstable video sources.

INSTALLATION
Plug the 5120 or 5125 module into any one of the slots in the tray and install the plastic
overlay provided onto the corresponding group of rear BNC connectors associated with the
module location. Note that the plastic overlay has an optional adhesive backing for
securing it to the frame. Use of the adhesive backing is only necessary if you would like
the location to be permanent and is not recommended if you need to change module
locations. This module may be hot-swapped (inserted or removed) without powering down
or disturbing performance of the other modules in the system.
CABLING
Refer to the 3 RU and 1 RU backplane diagrams of the modules below for cabling instructions. Note that both modules have identical rear connectors. Unless stated otherwise, the
1 RU cabling explanations are identical to those given in the 3 RU diagram.
Connect one of the serial
digital signals to be distributed
to the Serial In A BNC.
The CONTROL 15-pin
D-connector is not used
in this application.
Connect serial digital output
destinations to the outputs at
BNCs Out 1 A - Out 4 A.
Connect one of the serial
digital signals to be distributed
to the Serial In B BNC.
Connect serial digital output
destinations to the outputs at
BNCs Out 1 B - Out 4 B.

MODULE CONFIGURATION AND CONTROL
The configuration parameters for each Avenue module must be selected after installation.
This can be done remotely using one of the Avenue remote control options or locally using
the module front panel controls. Each module has a REMOTE/LOCAL switch on the
front edge of the circuit board which must first be set to the control mode you will be
using.
The configuration parameter choices for the module will differ between Remote and
Local modes. In Remote mode, the choices are made through software and allow more
selections. The 5120/5125 Parameter Table below summarizes and compares the
various configuration parameters that can be set remotely or locally and the
default/factory settings.
If you are not using an remote control option, the module parameters must be configured
from the front panel switches. Parameters that have no front panel control will be set to a
default value. The Local switches are illustrated in the Front Panel Controls and
Indicators section following the 5120/5125 Parameter Table.
Avenue module parameters can be configured and controlled remotely from one or both of
the remote control options, the Avenue Touch Screen or the Avenue PC Application. Once
the module parameters have been set remotely, the information is stored on the module
CPU. This allows the module be moved to a different cell in the frame at your discretion
without losing the stored information. Remote configuration will override whatever the
switch settings are on the front edge of the module.
For setting the parameters remotely using the Avenue PC option, refer to the Avenue PC
Remote Configuration section of this document.
For setting the parameters remotely using the Avenue Touch Screen option, refer to the
Avenue Touch Screen Remote Configuration section of this data pack following
Avenue PC.

TROUBLESHOOTING
As a troubleshooting aid, the signal equalization and presence, power and CPU status can
be easily monitored from the front panel of this module using the indicators explained in
the previous section.
If using the Remote mode, the following status items can be monitored using the Avenue
Touch Screen Control Panel or PC Application:
• Equalization (cable length)
• Power status
• Slot ID, Software Version and Board Revision
Refer to the overall troubleshooting tips given below for the 5120/5125 module:
No status lights are lit on front panel:
• Check that frame power is present (green LED{s} on frame power supplies).
• Check that module is firmly seated in frame. Try removing it and plugging
it in again.
Can’t control module:
• Check status of CPU Run green LED. Should be blinking slowly and in
unison with other modules if System module is present. If not, try removing
it and plugging it in again.
• System module may not be working properly if installed.
No signal out of module:
• Check status of EQ OK green LED. Should be lit. If not, check the input
signal for presence and quality.
• Check cabling to input of module.
• Check remote cable equalization by switching the module to Local using
the front panel switch and see if the EQ OK LED comes on.
