MODULE OVERVIEW
The 7405 module is a high definition test signal generator that provides four identical HD
serial outputs and two identical black outputs, all synchronous to one another. In remote
mode, vertical and horizontal timing of the six outputs can be adjusted relative to the
reference signal. A wide range of HD test patterns are user-selectable, in addition to
dedicated black outputs. There are independent enables in the remote control menus for
each test signal component so that Y, Cr, and Cb can be controlled separately.
The module can genlock to either a composite video (525/NTSC or 625/PAL) or a HD Trilevel sync signal. The sync reference can be selected to come from the Avenue frame
master reference or the external reference BNC on the rear of the module.
As shown in the block diagram below, the selected reference enters a sync detector circuit
where information is extracted to determine the format and create the correct synchonizing pulses for the timing generator. The timing generator is used by the test signal
generator to synchonize the black and pattern generators. The serializers convert the
parallel data stream to a serial differential pair which then passes to the output drivers.
The output drivers feed four identical copies of the selected test signal to BNCs on the
rear of the module. Two identical copies of the black signal are also available.
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.
The on-board CPU can monitor and report module ID information (slot location, software
version and board revision), and power status to the optional frame System Control
module. This information can be accessed by the user or set to register an alarm if desired
using the remote control options available. The CPU also communicates with the remote
control system.

APPLICATIONS
Test Signal and Black Distribution
As shown in the application below, the 7405 module can provide stable HD test signals to
facility HD routers and HD production switchers. An Avenue 5400 Dual Sync Generator
can provide the Tri-level or SD composite sync reference for the 7405 and then be looped
to the HD production switcher and other destinations if required.

INSTALLATION
Plug the 7405 module into any one of the slots in the 1 RU or 3 RU frame. 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 module below for cabling instructions. Note that unless stated otherwise, the 1 RU cabling explanations are identical to
those given in the 3 RU diagram.

signal to the Ref In BNC.
(This input is required
when the module is used
in Local mode.)
Connect the four copies of the
HD test signal on BNCs TSG
OUT 1 – 4 to high definition
destinations.
Connect the two copies of the
Black test signal output on
BNCs Black Out 1-2 to high
definition destinations.
Loop the reference signal
input to other destinations
from the Loop Out BNC.

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 desired control mode.
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 7405 Parameter Table on the following page summarizes and compares
the various configuration parameters that can be set remotely or locally and the
default/factory settings.
If you are not using a 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 7405 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.
