Pro-Bel Ltd
1 Introduction
The TX 410 Digital Master Control Switcher is designed to perform everything from basic transitions
to full multi-channel operation with a choice of either manual or automated operation.
The emphasis is on ease of use, with all commonly used functions available from a single button
press, and less frequently used functions accessible via soft keys associated with the integral
display. By making use of coloured buttons, button groups are differentiated by colour according to
their function. In addition, the LCD touchscreen provides the audio metering facility while doubling
up to provide access to system set-up and configuration screens, enabling on line changes to be
made without the need for an external PC or terminal.
The TX 410 provides every feature you need from a master control switcher. All the transition types
that you would expect to find in a master control switcher plus a choice of ten wipe patterns are
provided by the TX 410, as standard.
Up to two downstream linear keyers can be provided, enabling captions and logos to be inserted
into the programme video, with each keyer able to be independently cut or mixed to air, or preset to
follow the next transition. In addition, comprehensive control of a DVE to provide squeeze effects is
available as an option.
The four audio over inputs provided with the system have independent level control, and may be cut
or faded to air. Like the downstream keyers, the over facility can also be preset to follow the next
transition.
Enhanced audio facilities offer up to four AES levels for either balanced or unbalanced operation,
plus embedded or analogue options without the need for external converters. The panel also
provides the ability to modify audio level, phase and channel routing for each source.
Extensive routing options permit seamless integration with either the dedicated TX Series internal
routing system, or a larger station router via Pro-Bel’s Aurora control system. The internal router
supplied with standalone systems provides up to eight additional outputs which can be controlled
from standard router panels and used as monitoring or bypass outputs.
The “open system architecture” provided by the TX Series ensures that it can easily be integrated
with any automation system however, when used in conjunction with Pro-Bel’s own Compass and
Sextant automation packages the TX 410 has the ability to change the on-air schedule from the
panel, inserting events or modifying transition types by simply selecting them. Independent manual
intervention buttons provide direct operation of key automation functions.
Fully redundant power supplies in both the control panel and associated frames, and the ability to
‘hot swap’ any system module provide the on air reliability and ease of maintenance demanded in
the master control environment.
The integral LCD display with touchscreen and extra assignable panel buttons give the flexibility to
easily incorporate new features and operations within the system.
The display also provides ‘at a glance’ monitoring of audio levels and single keystroke access to
less commonly used operational functions. System set-up and configuration screens permit on line
changes to be made without the need for external equipment.
Comprehensive machine control facilities are provided as standard. The three machine control
ports can either be connected to dedicated machines, or assigned to operate with routed machines
via an RS422 router.
Notable characteristics of the TX 410 are:

Shipping brackets and transit screws
The control panel
A single transit screw is located beneath the front edge of the control panel. This should be removed
before proceeding further with the installation.
An additional securing screw to prevent the panel lid being opened during shipping, and after the
removal of the transit screws, is located beneath the red <PRE ROLL & TAKE> button. To access
this screw, lift off the button, and release the screw. Once released, the <PRE ROLL & TAKE>
button can be replaced.
WARNING: If the <PRE ROLL & TAKE> button is removed while the panel is active,
replacing the button may cause the next event to be taken.
For added security, and safety, during normal operation, the lid can be secured with this screw to
prevent unauthorised access to the PSU and control module contained within the panel.
The frames
For shipping purposes, modules in the control and router frames are secured in place with brackets
mounted by two screws on the sides of the power supply slots. These should be removed prior to
installing the frame.

Pro-Bel Ltd
Installing the equipment frames
The main and vision mixer frames should be installed in standard 19” wide equipment racks with
sufficient depth to accommodate cable bundles at the rear. Ensure that the cable bundle weight is
properly supported within the equipment rack to avoid undue stress on the connectors.
For safety reasons, all equipment racks should be securely fastened to the floor or wall to eliminate
the possibility of tipping.
After ensuring that all packing materials have been removed from the frames, align them so that the
screw holes match up with those in the rack and secure each frame with four rack screws and
washers.
As cooling is forced, using integral fan assemblies, care must be taken to ensure that the vents on
the sides (router and control frames) or rear (vision mixer frame) of the frame are not obstructed.
The following diagrams show the airflow through the frames.
The drawings show the frames with doors removed to aid identification. For correct cooling, the
doors must be fitted and closed.

Issue 2
Pro-Bel Ltd
TX 410 technical manual
Fitting and removing the frame doors
To prevent damage during transit, the frames are packed and shipped without having the doors
fitted. The doors are packed separately, and once the frames are installed, the horizontally hinged
doors can easily be fitted to the frames as detailed below.
For correct fitting of the door, hold the door at approximately 30° from the front of the frame ensuring
that it is centrally located above the hinge. The door can then be placed on the hinge and closed.
To remove the door from the frame, open it to approximately 30° and lift upwards. The design of the
hinge assembly prevents the door from being removed if it is at a greater angle.
For correct cooling, the doors must be fitted and closed except when access to the modules is
required.
Removing the frame door
Installing system modules
Note: It is not necessary to remove power from the frames when inserting or removing system
modules as they have been designed so that they can be inserted or removed from the frame,
while powered.
Inserting modules
In both frame types, the modules slide along guide rails in the frame and plug into connectors
attached to the motherboard, or rear connector assembly:
·
Ensure that the module is located in the correct position
·
Slide the card along the guide rail of the required slot, gently pushing it fully home until it
marries up with the connector
·
Connect ribbon cables, where applicable, by pushing them home until the catches locate
For modules equipped with a reset switch, it is recommended that the card is reset after inserting it
into a powered frame.
HU-TX 410T

TX 410 technical manual
Pro-Bel Ltd
Removing modules
For removal purposes it is advisable to remove the ribbon cables, where applicable, from the card
edge prior to removal.
·
Release the ribbon cables by pushing the catches up on either end of the connector as shown
in the following diagram
·
Lift up the card ejector on the module and gently pull the card out

Fitting rear connector panels
The rackframes are supplied with rear connector panels and, where necessary, blanking plates. In
cases where a frame is being upgraded, to add more audio levels for example, it may be necessary
to fit new rear panels. To fit panels, or to later change the position of a module, the procedure is as
follows:
·
Locate the correct position on the frame and remove any blanking plates or existing rear
connector panels
·
Before fitting a new rear panel ensure that the connectors mate on a one-to-one basis and that
there is no offset either vertically or horizontally. Misalignment could result in damage to the
connectors on the motherboard (Note that only minimal force is required for this operation)
·
Once fitted, secure the rear connector panel to the frame using the supplied fixings.
WARNING: Where screws are present, they form an essential chassis connection for
EMC compliance and must not be omitted

TX 410 technical manual
Installing the control panel
The TX 410 panel has been designed to either sit on the desktop or be flush mounted. The incline
on the panel ensures that all areas of the panel are visible when free standing, while the added
incline of the panels’ display ‘pod’ enhances the visibility of the LCD touchscreen.
Note: When installing the control panel, ensure that there is enough clearance to open the top fully
and that the rear of the panel can be accessed for cable connections.
Flush mounting the control panel
The base of the control panel fits into the cut-out (455mm x 345mm) from above. The panel has
three mounting flanges and can be secured by up to ten screws - four on each side flange and two
along the front.

The connectors Spare 1 and 2, provide access to the two groups of pushbuttons in the top left
corner of the panel, if they are wired out to the rear panel as detailed in section 5. These buttons
can be used to control any equipment requiring a closing contact, such as a bypass router.
However in systems where the Automation (MIP) function is used, or if the panel is to provide
control of more than one system, these buttons are used for that purpose and are therefore not
available externally.
Connecting the Automation port to the MIP (manual intervention panel) port on a Compass or
Sextant automation controller provides the operator with direct access to key automation controls,
permitting the ‘on air’ schedule to be effected without the need to access an automation edit
terminal.

Audio mixer
External audio mixer frames are only required if the audio mixer modules cannot be housed within
the main frame. This should only be necessary when systems with multiple levels of audio are being
built. Frames can house up to 4 audio mixer modules and are fitted with external mixer rear panels
as shown below. Audio control is connected via the rear ‘CONTROL’ connector and should be
linked to all levels fitted in this frame. The ribbon cable, running across the front of the audio mixer
modules, is also required to be connected to all of the fitted audio mixer modules.

3.2 Video signals
As the TX 410 can be supplied for operation with either an ‘internal’ (local), or ‘external’ router, all
signal interconnections between the router and the video and audio mixers require external cabling
as shown in the diagram below. The following sections detail these connections.
Note:
Items that appear in the diagram as shaded blocks are either optional, or are only required for
certain system configurations.
The number of DSKs required, for the system depends upon the system configuration.
The third PGM output is routed via the BNC labelled ‘KEY PVW’.
24
Issue 2
Pro-Bel Ltd
TX 410 technical manual
Vision mixer rear panel
3.2.1
Routed inputs (PGM/ PST)
For systems using an internal or local router connected directly to the TX Series controller, it is
possible to define which outputs are used for these functions via the control panel configuration
screens. In systems controlling an external router, via an external system controller, the routers’
system controller is used to determine the source and destination associations that are used.
Dedicated router destinations feed the PGM and PST inputs of the TX Series vision mixer frame
while two additional destinations, under the control of the TX 410 panel, provide the AUX1 and 2
outputs for video monitoring. These auxiliary (AUX) outputs do not feed the vision mixer, and can
therefore be connected directly to picture monitors.
3.2.2
Downstream keyers (DSKs)
On the rear of the frame the inputs for each of the DSKs are labelled ‘FILL’ and ‘KEY’ and the
outputs labelled ‘PVW’ and ‘O/P’. While the frame can house up to four keyers, the TX 410 only
provides control for a maximum of 2 keyers.
The keyer PVW (preview) outputs should be connected to a video monitor, either directly or via a
router, for monitoring purposes when Clip and Gain levels for each keyer are adjusted, without the
keyer being on air.
In addition, a copy of the keyer output enables feeds from different points within the signal path to be
used for transmission, or monitoring purposes.
3.2.3
Clean feed
A clean feed may be taken as an output for viewing, or distributing, the PGM video without the
DSKs or DVE squeeze. The TX 410 provides two clean feed outputs.
The signal is in serial digital video format to SMPTE 259M, and is also fed internally to DSK1, or the
DVE if it has been positioned upstream of DSK1.
3.2.4
PGM output
Three copies of the final PGM output are available on the rear panel. These are taken from the last
point in the programme chain within the mixer, and depend on the system configuration as defined
by the mixer configuration card. Full details for configuration of the video mixer can be found in
section 6.2. The BNC providing the third PGM output is labelled ‘KEY PVW’.

Pro-Bel Ltd
Connecting the DVE
The following diagram shows the rear panel of the Magic DaVE, DVE.
The signal connectors used when integrating with the TX 410 are as shown below:
As the DVE has an inherent one frame delay, it is necessary to have an equivalent frame of delay
from a frame synchroniser in the alternate path when the DVE is not active. When the DVE is not in
circuit, the PGM output is routed through the frame synchroniser path. When the DVE is taken to
air, the active picture to the PGM output is taken from the DVE path. All ancillary data is taken from
the delay path, unaltered. The vision mixer has provision for either an external, or an internal, frame
synchroniser.
It is recommended that the second DVE output is taken directly to a monitor, or that it appears as a
source on the router which is only accessible from the AUX bus (input 21 to 24) enabling it to be
selected and the DVE sequences previewed before use.
Note:
1. The audio mixer card (5025) is fitted with the ability to set an equivalent audio delay to
compensate for the DVE delay. This is set by jumper PL12 being in position 1 (see section 6.1).
2. If an internal, ICON, Frame Synchroniser module is fitted within the vision mixer frame the
external frame synchroniser module is not required. (see section 6.2.3 for setup of 3403 ICON
module).

Pro-Bel Ltd
TX 410 technical manual
3.3 Audio signals
As with the video signals, it is necessary to feed, for each audio level, the PGM and PST inputs of
the audio mixer from two router outputs. For systems using embedded audio, these router
destinations are taken from the video router. A further router output, for the AUX bus should be
connected into the mixer enabling the Aux bus to be monitored not only by the control panel
metering, but also from the audio monitor outputs.
The TX 410 accepts up to four audio over sources, which can be configured to be fed either from a
single router output, permitting selection of four router sources, or from four dedicated audio over
inputs on the rear of the mixer.
The audio connections shown above are common across all signal formats, however the use of
on–board converters and dedicated backplanes permit the system to be adapted for AES (balanced
and unbalanced), embedded or analogue operation. Details for audio mixer configuration of these
audio formats are covered in section 6.1.
Because the TX Series electronics are compatible with both the TX 410 and TX 420 panels,
references to Aux 2 and Mon 2 have been left in the following sections detailing the signal
interconnections for different audio formats, even though the TX 410 does not provide control for
them.
Multi level audio
Where more than one audio mixer is required within a system, for example; in a multi-level audio
system, the audio mixers must be housed within the same frame as they share audio signals via a
card edge ribbon cable. This allows channel swapping across all of the audio levels within the
system. Additionally, the system only requires one multidrop control connection from the main frame
for mixer control.
Because signals are passed between audio mixers via the card edge ribbon cable, the monitoring
output from the first audio level provides audio monitoring for all levels. Selection of which audio
level to monitor is made by a soft button on the Audio Setup screen. Further details can be found in
the operators guide in the ‘Using the audio monitoring’ section, while further information covering
installation of multilevel audio systems can be found in section 8 of this manual.

Balanced AES
The main frame and external audio mixer rear panel for balanced AES operation can also be used
for systems with embedded or analogue audio.
There are two operating modes available to the mixer, mode 0 and 1, which determine how the
mixer channels are fed. Before connecting any audio inputs to the mixer, it is important to check
which mode the mixer has been set, or is required, to operate in. For more information about setting
the mixer mode, see section 6.1.
For systems where all inputs are AES, either operating mode can be used, however if the system
requires analogue audio over inputs, mode 0 should be used.

Pro-Bel Ltd
Embedded audio (balanced AES over)
Systems supplied for use with embedded audio and balanced AES overs use the same frame/ rear
connectors as those used for balanced AES operation, shown in section 3.3.1.
Audio inputs
The audio mixer module is fitted with five AES extractor submodules for the PGM, PST, AUX 1,
AUX 2 and Off Air return (TX) inputs, fed from the rear panel BNCs labelled A to E.
Four outputs from the video router, independent of those supplying the vision mixer, should be
assigned for the PGM, PST and two AUX busses, ensuring that video/ audio breakaway operation
is available within the system.
In multi level audio systems, it is necessary to feed these router outputs to every audio mixer. As
most routers provide only one or two outputs per bus, distribution amplifiers are used to buffer the
feeds from the PGM, PST and Aux busses to the respective inputs on each audio mixer.
The mixer should be set to operate in ‘mode 1’, and the router outputs connected to the audio mixer
inputs as detailed in the following table.

Audio overs
The over inputs, when operating in an embedded system, can be wired in two ways;
1) As balanced AES inputs. This is the most common implementation, feeding the audio mixer
inputs 13, 1, 2 and 3, via the 50 way ‘D’ type input connector, as shown in the previous sub
section for the balanced audio system (mode 1), or
2) As an embedded source from the router. To operate in this way, an output from the router
should feed the fifth embedded input BNC (E) replacing the Off Air input and the extractor
submodule used for Off Air (position 8) should be moved to position 7, the Over input on the
mixer (see section 6.1). The system must then be configured to control a router destination for
the over inputs, with sources 21 to 24 used as over inputs 1 to 4 respectively. If the Off Air input
is still required it can feed audio mixer input 15, as balanced AES, via the 50 way ‘D’ type input
connector.
32
Issue 2
Pro-Bel Ltd
TX 410 technical manual
Outputs
The audio mixer provides a balanced AES PGM output which can then be connected, using a pin to
pin cable, to an embedder module housed within the vision mixer frame. The dedicated slot is wired
to accept up to four audio channels which can in turn be embedded into the Main PGM video
output.
As an earlier embedder module (4422) supplied with the TX 410 was a two channel device, the
frame design took this into account by allowing the inputs to be wired, as shown below, into the
ports marked 1 (1) and 3 (2). The numbers in parenthesis represent the input channel numbers for
a two channel device.

Unbalanced AES
The main frame and external audio mixer rear panel for unbalanced AES operation can also be
used for systems requiring embedded audio with unbalanced over inputs.
Before wiring the audio inputs to the mixer, it is important to check which operating mode the mixer
has been set to, or is required to operate with. Mode 0 or 1 can be used with unbalanced AES
configurations; however it is recommended that ‘Mode 0’ is used for these configurations as it
provides greater flexibility and ease of connection. For more information about setting the mixer
mode, see section 6.1.

Audio Over inputs
Mixer Mode 0
Overs 1 to 4 should be connected to inputs A to D as detailed in the Audio inputs table above.
Mixer Mode 1
In order to have access to all four audio over inputs, they can be wired in two ways;
1) As four unbalanced AES inputs to inputs E, 2, 3 and 4.
2) As a routed source. To operate in this way, an output from the router is used to feed the input,
marked E, in place of the Off Air signal. The unbalanced to balanced submodule in position 8
should be moved to position 7 and the system configured to control a router destination for the
overs. Sources 21 to 24 on the router are then used as over inputs 1 to 4 respectively.
The Off Air input can, however, still be used in either of the following ways;
i) As a balanced AES source to input 15 – This option requires no additional submodules, or
ii) As an analogue source to inputs 15 (left) and 16 (right) – providing an ADC submodule is
fitted in submodule position 7 on the audio mixer.
Reference input
When using the Unbalanced reference input, it is necessary to link pins 2 to 4 and 6 to 7 on the
Balanced AES Reference mating connector and plug it onto the AES reference input connector.
This ensures that the reference input is correctly terminated.

Audio overs
In order to have access to all four audio over inputs, they can be wired in two ways;
1)As four unbalanced AES inputs to inputs E, 2, 3 and 4.
2) As a routed source. To operate in this way, an output from the router is used to feed the
input, marked E, in place of the Off Air signal. The unbalanced to balanced submodule in
position 8 should be moved to position 7 and the system configured to control a router
destination for the overs. Sources 21 to 24 on the router are then used as over inputs 1 to 4
respectively.

The Off Air input can, however, still be used in either of the following ways;
i) As a balanced AES source to input 15 – This option requires no additional submodules, or
ii) As an analogue source to inputs 15 (left) and 16 (right) – providing an ADC submodule is
fitted in submodule position 7 on the audio mixer.
Reference input
When using the Unbalanced reference input, it is necessary to link pins 2 to 4 and 6 to 7 on the
Balanced AES Reference mating connector and plug it onto the AES reference input connector.
This ensures that the reference input is correctly terminated.

Outputs
The audio mixer provides unbalanced AES outputs for PGM, PST, MON 1 and MON 2.
A dedicated slot housing an embedder module in the vision mixer frame is wired to accept up to
four audio channels which can in turn be embedded into the Main PGM video output.
As an earlier embedder module (4422) supplied with the TX 410 was a two channel device, the
frame design took this into account, allowing the first two audio levels to be connected into the
BNCs labelled 1 and 3. The corresponding 9 way connectors are labelled 1 (1) and 3 (2), where the
numbers in parenthesis represent the input channel numbers for a two channel device. This can be
seen in the picture below.

TX 410 technical manual
Analogue audio
The analogue TX 410 system is uses the same rear connector assembly as balanced audio
systems. Before wiring the audio inputs to the mixer, it is important to check which operating mode
the mixer has been set to, or is required to operate with.
Systems using an analogue audio router to provide the PGM, PST and AUX inputs should be set to
‘mode 1’, as this allows ADC submodules to be fitted to the audio mixer for these inputs. For more
information about setting the mixer mode, see section 6.1

4.3 Stop watch and timer modes
The timer modes shown on the display are configurable. For details of how to configure them
please refer to section 5.5. The subsequently available modes are either stop watch (TOD) or timer
mode.
Each timer mode has a dedicated set of control pushbuttons, available on the timer home page,
these are shown below.
4.3.1
Stop watch mode (TOD)
In stop watch mode the time of day display (HH:MM:SS) is provided in 24 hour format, as illustrated.
This time is derived by the station TC input. If no input is present, the clock will free run.
The stop watch is locked to the station TC input. Due to this feature a count started half way through
a second will count that half second as a second to keep in step with the station TC.
When stop watch mode is selected, the current count is displayed along with three push button
controls for the stop watch, as illustrated. The stop watch can count up or down (from a preset
value) and can be reset. The count down preset value is selected using the left hand shaft encoder
to set the minute (MMM) value and the right hand shaft encoder to set the second (SS) value.
The stop watch once started counts continually until terminal count, and is not affected by display
pages being changed.
·
A toggle push button provides <COUNT> indication. On system startup the stop watch is
shown as stopped, after which it always displays the current operational state as set by the
operator. The button is highlighted when running. When the stop watch reaches terminal count
(999:59 or 000:00) the count state is changed from start to stop. The timer can also be started
and stopped from the audio monitoring home page by pressing the timer indicator MMM:SS
50
Issue 2
Pro-Bel Ltd
TX 410 technical manual
·
A toggle push button provides <UP> and <DOWN> indication. On system startup the stop
watch is shown as <UP>, after which it always displays the current operational state as set by
the operator. When the stop watch reaches terminal count (999:59 or 000:00) the count
direction indication remains unchanged.
·
A push button provides stop watch <RESET>. If selected while counting up the count is reset
to zero and the count continues. If selected while counting down, the preset count down time is
reloaded and the count continues.
4.3.2
Timer mode
If timer mode has been configured, the display can be switched between segment and remaining
mode. In either mode, the TOD display is replaced with a display showing the time the last transition
was made. This is updated after every PST/PGM transition.
The timer is locked to the station TC input. Due to this feature a count started by a transition half
way through a second will count that half second as a second to keep in step with the station TC.
4.3.3
Segment timer
In segment mode the timer value is displayed along with four push button controls. The segment
timer counts independently of the stop watch and remaining count and it is always active, even if
timer mode is never selected.
After each transition the timer automatically starts, counting up each second, and can only be
stopped either manually or when the terminal count of 999:59 is reached.
The <SEG HOLD> push button overrides the auto start by preventing the count from being zeroed
at the start of each transition.
The <RESET> push button resets the count to zero. If the count is running when this is pressed, it
will reset to zero then continue counting.
4.3.4
Remainder timer
In remainder mode the timer value is displayed along with three push button controls, and counts
independently from the stop watch. The segment count is always active, automatically starting after
each transition, counting from the preset value, or zero if none has been specified. and can be
manually started and stopped once counting.
Once active the timer counts down each second and only can only be stopped manually or when
the terminal count of -999:59 is reached.
The time preset is set using the left hand shaft encoder to set the minute (MMM) value, and the
right hand shaft encoder is to set the second (SS) value.
The <ENTER>push button only appears if the remaining count has been stopped and a positive
remaining time is visible on the display. Selecting this push button calculates the duration of the
programme remaining from the last transition by performing the calculation shown. The push button
is then removed from the display and the duration is displayed as the remaining count which is
automatically started (the <COUNT> push button automatically toggles from stop to start).
Duration = currently remaining count - (time of day - time of transition).

5.3 Transition rates
To access this page from the system configuration page, press the <TRANS RATES> button.
This page allows the system transition rates to be modified, and set, and also enables flip-flop
operation of the PGM bus to be activated
The <HOME> button returns the display to the system configuration page.
5.3.1
Changing the transition rates
The transition rate setup page allows the three transition rates for the system to be adjusted and
set. These three rates, <SLOW>, <MED> and <FAST> determine the rate a PST/PGM transition
occurs at, and are recalled by selecting a transition rate button from the bottom left hand corner of
the control panel.
Each of the three current settings is shown on the left of the screen, as the number of frames over
which the transition will occur, in the relevant button.
The default settings are:
·
fast = 12 frames
·
medium = 25 frames
·
slow = 50 frames
To adjust each rate, select the required rate button. The currently selected button is shown with
inverse text. The selected transition, and current rate, is shown below the rate bar in the centre of
the screen
The rate is adjusted by using either shaft encoder below the rate bar. Turning the shaft encoder
clockwise increases the number of frames, while turning it anti-clockwise decreases the value.
56
Issue 2
Pro-Bel Ltd
TX 410 technical manual
The bar, numeric value beneath it and the rate button all reflect the changes being made, however
these new settings will not take effect until they have been saved. To save the new settings, press
the <Save> button in the top right corner of the screen. This saves the new settings.
5.3.2
Configuring ‘flip-flop’ for transitions
The <Flip Flop> button on the right hand side of the transition rates page can be toggled to enable
(button highlighted) or disable (button not highlighted) flip-flop operation.
Flip-flop mode, when activated, swaps the PST and PGM sources at the end of a PGM bus
transition.
Note: When using the TX 410 with Pro-Bel automation systems, it is important to ensure that Flip
Flop mode is NOT active as the action of selecting sources on the PST bus inserts manual events
into the schedule.

5.4 Configuring fade to black options
In addition to the ability to define the fade rate for the fade to black/ silence, when using the ICON
vision mixer, the fade to black function can be changed to be fade to colour. Pressing the <FTB>
button on the system configuration page opens the fade to black page.
5.4.1
Fade to black rate
Either shaft encoder below the display adjusts the fade rate, which is displayed in frames. The
possible range of values is between 0 and 99 frames, where 0 = cut.
Changes being made to the fade to black rate are displayed on the bar, and the numeric value
beneath it. These changes are automatically saved as they are modified.
With the ICON vision mixer, the fade to black function can be positioned either before or after any of
the keyers in the video path, see chapter 5.7.3.
It should be noted that, when the TX 410 is used with the S&W mixer, the <FTB Color> button is
not displayed, and an additional button <FTB Posn> is displayed allowing the fade to Black function
to be positioned either before or after DSK 2.

Router configuration
Selecting the <ROUTE CONFG> button provides access to the Router Configuration screen,
where the router control options offered by the TX 410 can be set.
Three control modes are available; 'local', 'external – sys 3' and 'external - auto'. The currently
selected mode is shown using inverse text on the button. Once the router type has been
configured, pressing the <HOME> button returns the display to the Source setup page.
‘<LOCAL>’ control mode, in this case, refers to any router under direct control of the
TX Series controller using Pro-Bel general switcher protocol (SW-P-02). The router can either
be a dedicated TX Series router housed in the TX Series controller, or a separate framed
router such as Freeway connected via the Ext Rtr port on the TX Series controller.
'<EXT SYS 3>' and '<EXT AUTO>' should be selected for systems where the TX Series
controller uses an external controller, such as Aurora, for router control and to assign sources
to the system.
The Aurora <EXT SYS 3>/ Automation <EXT AUTO> interface
For external router control via an Aurora controller to operate, the router configuration page must be
set for either '<EXT SYS 3>' or '<EXT AUTO>'. In addition, the physical link between the Aurora
and TX Series controller is via a single RS-422 link between the TX 410 controller, Ext Rtr port, and
a panel port on the controller.
The TX 410 emulates 2 Multi-drop panels on this port, at the first and second positions. The panel
type used is ‘Master Control’ and each panel should be configured with a different suite number
(refer to the control system documentation for further details). The first panel is used to control the
Video crosspoints (PGM, PST and AUX 1), while the second panel is used for Audio crosspoints
(PGM, PST, AUX 1 and Over). Note that if dedicated overs are used the last destination, over, is not
required. This interface then operates in one of two modes as follows.
64
Issue 2
Pro-Bel Ltd
TX 410 technical manual
Mode 1 - <EXT SYS 3>
In this mode all assignments to channels are made separately using a channel assignment panel
connected to one of the panel ports on the Aurora controller. This panel should be configured to use
video and audio panels with the same suite numbers as the ‘pres panel’. Any assignment to
channels made from this panel will then be reflected on the TX 410.
Mode 2 - <EXT AUTO>
In this mode the assignments to the channels are set as described for the Ext Sys 3 mode, via a
channel assignment panel, however they are not fixed. The TX 410 will assign a source to a
channel, if the source requested on the automation port is not currently assigned to the panel.
When a command to set a channel, on a bus is received from the automation port, the channel
number is assumed to be equal to the association number on Aurora. This source association
number is assigned to a channel. The video and audio suites are expected to have the same panel
assigned and will always have the same source association assigned for both video and audio.
When a source is requested via the automation port, the TX 410 will check the source association
against those sent by the system controller and if found, the matching channel will be used. If it is
not found, then the highest unused channel will be assigned that source association. The maximum
number of channels that can be automatically assigned is 8 (channels 5 to 12). These sources are
assigned from the right hand side of the mixer bus.

Local Route
The <LOCAL ROUTE> button is only visible on systems set to operate with a ‘Local’ router.
From this screen, the communication link between the controller and ‘local’ router can be
specified. This can be set using the <RS232> or <RS422> buttons. Systems using a router
housed within the control frame should be set to <RS422>.
The third button on the screen allows the local router type to be defined. The button toggles
between the two options, <TM24> and <HD16>, enabling the switcher to operate with either a
24 or 16 input router. This feature permits the system to be configured as an SD system,
using a 24 input router, <TM24>, or an HDTV system using a 16 input router, <HD16>.
By defining a router type, sources are ‘mapped’ according to the router size, to the correct
buttons on the panel. The 24 input router uses inputs 1-12 for the prime sources and 21-24 as
the additional four Aux bus sources, while with a 16 input router, no mapping is required.

VTR sources
The <VTR SRCS> button opens the VTR control sources editor page.
This page enables RS 422 router inputs (VTR control sources) to be associated with PGM/ PST
bus sources.
The Machine Control port should be cabled to the router as follows;
TX/RX1 - Controls the machine on the PST bus, TX/RX2 - The Aux1/2 machine and TX/RX3 provide the RS422 router control to its remote control port.
In the diagram above, VTR1 is connected to source (input) 15 of the RS-422 router while the output
is connected to the TX Series controller. The screenshot at the beginning of this section shows
VTR 1 (source 15) is associated with the PGM/ PST bus source which is labelled 'VTR1'. When
VTR 1 is selected on the PST bus, source 15 on the RS 422 router will be connected to the TX
Series controller.
To edit the VTR control source for an input, select the required source by touching the screen. The
source is then bound by a rectangle, and changed using the shaft encoders below the display. The
VTR control source is displayed next to the input name, where '- -' indicates no VTR source and
numbers in the range 1 to 64 indicate the RS 422 router source number. The same RS-422 source
can be used with more than one mixer source.

VTR Destinations
On pressing the <VTR DEST> button the operator is taken to the VTR control destination editor
page.
This page enables RS-422 router destinations to be assigned, as controllable destinations, for the
Preset and Aux busses. When a VTR is to be controlled, the VTR control source number is routed
to the required destination on the RS-422 router making the duplex link from which the VTR can be
controlled. The controlled destination depends on which router bus is in use.
The VTR control destination is displayed on a single line with '- -' indicating no VTR control
destination or a number in the range 1 to 64 indicating the RS-422 router destination number.
The left hand shaft encoder controls the Preset destination, while the right hand shaft encoder is
used to configure the destination for the Aux bus. Once a destination number has been modified, an
<UPDATE> button appears above the <HOME> button. Pressing <UPDATE> accepts any
changes that have been made.
If only one destination is set, or if the same router destination is assigned to both the preset and Aux
destinations, a warning ‘Invalid destinations’ is displayed on the screen. When in this state,
pressing <UPDATE> will have no effect.
The <HOME> button returns the display to the source setup page.

Router Destinations
Pressing the <ROUTE DEST> button opens the Local router destinations top page. From here,
the Video and Audio router destinations of the local router can be selected and assigned to the TX
System.
The video and audio pages allow the local router destinations to be assigned to the PGM, PST,
AUX, Over (audio) and PGM follow busses, see section 5.6.9. For systems where a system
controller provides the interface between the TX system and router, changing these settings will
have no effect on system operation, except audio over, where ‘- -‘ indicates the use of dedicated
audio over inputs, and ‘NN’ specifies the destination number for routed audio over inputs.
The local router destination is displayed next to the bus name as a number in the range 1 to 64 or a
'--' indicating there is no destination assigned to the bus.
To edit the destination number for one of the controlled busses, touch the required bus on the
screen to select it. The selected bus is then bound by a rectangle and the destination number
displayed alongside the bus name can be changed by using either of the shaft encoders below the
display.
The range of values selected/ displayed may 'jump' or miss destination numbers as the system
does not allow the same destination to be specified more than once. The destinations specified
must include any offsets required to ‘stack’ the commands down a single RS-422 port, enabling
separate video and audio destination numbers to be selected.

PGM follow
The TX Series provides a programme follow facility, for use with systems using Local/ Internal
routing, allowing up to two, video/ audio, router outputs to ‘follow’ the main PGM bus.
These additional busses, PGM 1 and 2 provide cuts only transitions and can be used as a ‘shadow’
output for the PGM bus. These can be fed into an emergency/ bypass switcher, or be used to
provide ‘clean’ outputs for recording, or other as regional feeds. For these to operate correctly, each
bus should be assigned a destination number to control (see section 5.6.8) and source associations
to select.
Source associations can be set for each ‘follow’ bus, with independent control over video and audio
(providing all audio levels in multi-level systems are married) outputs, enabling PGM breakaways to
be achieved.

Follow source associations for each of the twelve PGM bus sources can be defined as a source
between 1 and 64, up to the maximum size of the local router. The ‘follow’ source number is
entered and displayed next to the PGM bus source name. If, however, there is no follow source for
a specific PGM bus source, it is indicated as '- -'. When this source is selected during normal
operation, the follow bus will remain on the last selected source.
As an example in the diagram above, for PGM 1 Video bus, sources VTR1 to VTR3 have PGM 1
follow associations. If source 'VTR1' is routed on the programme bus then source '14' will be routed
to the programme follow destination. If source '- -' (no source) is selected as the follow source for a
PGM bus source (e.g. 'SVR1'), then when 'SVR1' is routed on the programme bus, whatever was
routed on the associated follow destination previously will remain unchanged.
To edit a source association, select the required source by pressing it on the touch screen. The

5.7 Video path setup
By selecting <VIDEO SETUP> from the System Configuration page, the video path setup screens
provide the ability to define which DSKs are present in the system, their operating mode, adding
DVEs into the system. In addition, when using the ICON vision mixer, the order/ position in which
the DSKs, DVE and FTB functions appear in the programme path can be set.
5.7.1
Configuring the DSKs
A downstream keyer (DSK) enables images such as captions and logos to be displayed on top of
the programme. The TX 410 can be configured to control up to two DSK cards in the vision mixer
frame. These cards, type 3423, are interchangeable providing the correct line and fraction settings
are made. The settings for these cards are detailed in chapter 6.2.1.
The operating mode of the downstream keyers is set via the video setup screen. This page is
accessed from the system configuration page by pressing the
<VIDEO SETUP> button.
DSK operating mode
Selecting <VIDEO SETUP> returns the screen to the Video Setup page, where the <MODE> key
for each keyer toggles its operational mode between caption <CAPTN> and effects <FX>. The
current status is shown on the screen under the heading ‘Mode’, alongside the keyer. If the keyer
has been removed, the mode is set to N/A, indicating that it is not available.
In caption mode, the background signal is attenuated by the key in the caption area, and then the fill
is added over the entire picture. The fill signal must be presented against a totally black background
in order to avoid output in unwanted areas of the picture.
In effects mode the keyer produces a mix of the foreground and background inputs. With no key or
with black as key, then output is 100% background and the foreground input is off.

Selecting the follow mode
The follow mode allows each keyer to be set to follow a PST/PGM video transition, a DVE move or
both. The <FOLLW> buttons associated with each DSK are used to select the mode for each DSK.
·
<FOLLOW PGM> sets the DSK to follow PST/PGM video transitions only.
·
<FOLLOW DVE> sets the DSK to follow DVE moves only.
·
<FOLLOW BOTH> sets the DSK to follow either the next PST/PGM video transition or DVE
move.
As with the Keyer mode, the current status is shown on the screen under the heading ‘Follow’,
alongside the relevant keyer.
Adding and removing keyers from the system
The default, and maximum, number of keyers available with the TX 410 is two. To add, or remove
keyers, press the <VIDEO ORDER> button to access the Video path setup screen. The diagram
shows which keyers are currently configured within the system.
Pressing the <DSK 1 IN/OUT> and <DSK 2 IN/OUT> buttons in the bottom left hand corner of
the screen, to toggle between DSK In and DSK Out, the system can be ‘told’ how many keyers are
fitted in the vision mixer frame. When the keyers appear in the diagram, they are configured into the
system, and pressing the <DSK X OUT> button removes the keyer from the system. The button
label then changes to be <DSK X IN>. Note that removing DSK 1 from a system where two
keyers have been configured in circuit effectively removes both keyers.
It is important to set the number of keyers available to the system before defining the
operating mode for each keyer. These commands will only affect video order if the rotary
switch on the 3428 module in the mixer frame has been set for dynamic control, see section
6.2.2.
Once the DSKs have been configured into the system, pressing the <HOME> button returns the

contributing to the PGM output will have its gain reduced as the result of an audio over being taken
to air.
If the Preset fader position is set to <POST>, the PST bus fader is positioned after the audio over
fader. When configured in this way, the PST bus, when contributing to the main output, for example
during a mix transition will be at full level.
5.8.2
Audio Over follow
The over follow mode acts in the same manner as the DSK follow, except it follows an audio
transition, DVE move or both.
Pressing the Over Follow, <OVR FLW>, button cycles the over follow selection through the three

On pressing the <SYS VERSN> standard button the operator is taken to the installed system
software version information page. This displays the version information for the display control
system, main control system and the audio mixer.
The top line indicates the overall release of the installed software. The version information is the
highest release number and its associated sub-release number from all the EPROMs for which
version information is available. The release is taken as a beta release if any of the EPROMs within
the system are indicated as a beta release.
Each EPROM displayed has the form SPxxx/yyz, where xxx is the EPROM number, yy is the
EPROM version number and z is a beta release indicating character. The beta release character is
an ASCII character starting from 'A', with a space indicating a formal release of that EPROM.
Each version number has the form Vxx.yy, where xx is the release version number of the EPROM
and yy is the release sub-version number of the EPROM. If the EPROM is displayed as
SPXXX/XX, VXX.XX then there is no version information available.

6 Hardware configuration
This section has been provided as a guide to the settings required on each of the boards contained
within the system. The Pro-Bel module number, where applicable, is listed in brackets for ease of
identification. These numbers can be found on the card ejectors.
To access the Pro-Bel cards, open the frame doors as shown in section 2. To open the DVE frame,
remove the four screws from the front corners and pull the door forward to remove.
The switch/jumper and LED numbers indicated in the table are silk-screened onto the boards
themselves beside the relevant part.
6.1 Audio Mixer (5025)
The 5025 is a sixteen input, six output digital audio mixer. The basic module provides operation for
balanced AES inputs and outputs; however it has been designed to accept up to six input
submodules, permitting it to be configured for operation with embedded, analogue or unbalanced
AES audio inputs. An additional slot for a digital to analogue converter on the Programme output
further enhances the flexibility of the mixer.
The board layout is as shown below:
The DAC position can only be occupied by
a 5635 DAC, providing an analogue
version of the Programme output.
Positions 3 to 8 can be populated with
extractor modules, unbalanced to
balanced AES converters; ADC’s or
Sample rate converters. Each of these
submodules converts their respective input
into a balanced AES signal so that it can
be processed by the mixer.
The sub module types are as follows:
AES extractor (5026)
Analogue to Digital converter (5634) and
Unbalanced to Balanced AES converter
(5027)
Sample Rate Converters (5636)
At the rear of the module there are five sub miniature BNCs (1 to 5) that connect to BNCs A to E on
the rear panel respectively. These are used in to bring signals from the BNCs, using miniature coax
cables, to the extractor and unbalanced/ balanced converter submodules. Typically, they would be
wired as shown below; however the submodule indicated in position 8, may be repositioned as
described below to accommodate Over 1.

6.2 Vision mixer configuration
The basic vision mixer consists of two card types, the 3423 Keyer/ Mixer and the 3428 configuration
(config) card. Additional modules such as the 3403 frame synchroniser and 4422/ 4425 embedder
modules can be added to the system where necessary.
The 3423 provides the mixing and keying functions within the system, while the 3428 ensures the
correct routing of the programme signal between these video processing modules.
Embedded audio systems are supplied with an embedder module, type 4422 or 4425 dependent
on the system age (Note: These cards are not interchangeable), while the DVE option can also be
supplied with a frame synchroniser, type 3403, to compensate for the DVE insertion (framestore)
delay. These optional modules are covered in their technical manuals.
The simplified block diagram below shows the system architecture and signal path.

To ensure that the video inputs to each card fall within its timing window (if the signal sources are all
from exactly timed outputs), the keyer cards need to have their line/fraction delays set as follows
using switches on the front of the cards, if they are in local mode (Actual switch column), or by using
COSMOS (using actual offsets as described), if they are in remote mode. If the signal sources are
not from exactly timed sources, the cards must be timed according to the instructions in the timing
adjustments section.

Timing adjustments
The 3423 Keyer/Mixer is provided with an on board timing generator to enable the unit to be easily
integrated into a variety of system designs as flexibly as possible. Timing adjustment may be
performed from the card edge in local mode using the manual line and fraction delay controls
Each input has a variable one line delay,
and normal keying and mixing can occur
providing all three inputs are within a total
timing spread of one TV line.
The card generates its own internal
reference which may be locked to an
external analogue reference, when
selected.
The internal reference may be advanced
or retarded by -5 to +4 7/8 lines to allow
the inputs to fall within the timing window.
This allows the unit to be used with a
reference that is between 4 7/8 lines
earlier and 5 lines later than the required
output timing.
The internal reference may be timed
manually by using the line and fraction controls or automatically by pressing the Auto Time button.
When all three inputs are within their timing windows, each Range LED will illuminate green. The
Range LED will not illuminate for any input that is out of range. Orange illumination on the auto time
LED indicates that the auto-timing function is seeking the best timing.
Note: Corresponding controls are provided by COSMOS when in remote mode.

Pro-Bel Ltd
TX 410 technical manual
Line and Fraction adjustment
For the three video inputs to be synchronised for keying and mixing, they must each lie inside their
one line timing window. This is shown in the following diagram.
The auto-phasing timing window may be thought of as a variable one line delay through which each
SDI input passes. Once all the inputs are centred within their window the amount of delay is
automatically adjusted for each input to give constant output timing. This will hold true despite
changes in input timing, providing those changes remain within the correction window range. Larger
changes in input timing can only be accommodated by re-adjusting the internal reference timing to
bring all the inputs back inside the timing windows. This is achieved by pressing auto-time or by
adjusting SW 7 and SW 6 until all the Range LEDs illuminate green.
It is not recommended to use Auto time in the TX frame due to the system operation. It is normally
best to set the timing as early as possible and NOT in the middle.
Note: The delay through a single card is ⅛ of a line therefore it is advisable to set the mixer
card to the earliest possible timing to allow the 4th Keyer card, where used, ½ line flexibility for
the Key and Fill inputs.
The early settings accommodate an input earlier than the reference and should not be taken
to imply that the unit can advance the input.

Differently timed inputs can be accommodated providing timing variations are less than one line.
Proceed as follows to work with a number of differently timed inputs:
Start at the earliest reference delay setting with SW 6 at 5 and SW 7 at zero - all range LEDs should
be off
Increase SW 6 until all range LEDs are green
Go back one position on SW 6
Increase SW 7 until all range LEDs again go green - if necessary increase SW 6 by one position
and set SW 7 to zero
Note this setting in lines and fractions - it represents the earliest valid setting
Increase SW 7 until one range LED turns off, then go back one position on SW 7 - if a range LED
does not turn off, increase the setting of SW 6 by one position, set SW 7 to zero and continue as
before
Note this setting in lines and fractions - it represents the latest valid setting
Choose a reference delay as required between the earliest and latest reference delay settings noted
above.
Once the mixer card has been timed, the setting for each of the keyer cards, Keyer 1 to 4 should be
increased by 1/8 of a line relative to the previous card.

The 3428 can operate in either of two modes, independent or serial control. With the 3428 module
set for ‘local’ (DVE switch set in positions 0 to 5), the mixer will ignore settings made from the
system control panel configuration screen, and will read the mixer configuration from the piano type,
and rotary, switches located at the card edge. Conversely, with the module in ‘remote’ mode (DVE
switch set in positions 6 to 9) any settings made from the control panel will be used to determine the
system operating mode.
On reset, the module will initially revert to the switch settings until a command is received from
the TX Series controller.

This set-up means that the card is set for 625 operation, in remote mode, no audio embedder
present and pinswap is off.
If however in this configuration the mixer does not talk with the TX controller, try changing SW3-4
(labelled as PVW_BUS) this will invert the Tx & Rx pins.
Note: While Fade to Black can be positioned after any DSK, this is a control function only as each
DSK has its own fade to black function. No video switching is required for this function.
DVE positioning in the programme path
The vision mixer architecture has been designed to enable the DVE to be positioned anywhere in
the PGM video path. The DVE position is determined by the card edge rotary switch on the 3428
mixer configuration module, for either fixed or dynamic positioning via the video setup screen.

7 TX Series routing
7.1 Internal routing modules
The TX Series routing modules, available in Serial Digital Video and AES Digital Audio, each provide
a 24x12 routing switcher level. This section of the manual covers the installation, configuration and
operational alignment of these routing cards.
Within a system equipped for single level audio, the video and audio router modules are housed in
the main TX control frame. For systems with more than one audio level, these router cards are
housed in remote 3RU frames and connect to the TX controller via an RS485 control connection to
the remote router port (RTR). In both of these configurations, the routers are controlled as a local
router.
Remote router frames house up to four router modules and can be ‘stacked’ to work together,
permitting systems with video and up to four audio levels to be constructed in two frames.
Each TX routing system requires a control module, containing the router configuration data, which is
housed on one of the router modules. As the TX system does not use all of the twelve available
outputs on the router (four in discrete audio systems and eight in embedded systems), a control
panel port fitted to the TX control system (or device port on remote frames) permit these additional
destinations to be controlled using standard Pro-Bel control panels.
For the TX router to operate correctly, the controller must contain a valid database, and each
module should have its level address switch set correctly. The following paragraphs detail the level
switch settings, and how to connect the router configuration editor to the system.

Setting the level switch
A TX Series master control routing switcher can comprise of up to five levels, video and four audio,
accommodating the multi-level audio processing supported by the TX Series master control
switchers.
Note: As audio breakaway between router sources, on multi-level systems, is carried out
within the audio mixer it is necessary for the TX controller to switch all audio levels
together, i.e. married. In this case, the address for every audio level should be set the same.
The Level address switch can be found on the front card edge and should be set, depending on
level type, as follows:

Serial digital video router (3678)
The TX Series serial digital video router is fitted with 24 equalising inputs and 12 reclocking outputs.
The adaptive cable equaliser on each input provides automatic equalisation for different lengths of
cable, while the output reclocking circuitry guarantees exemplary signal quality ensuring fully
transparent operation for ancillary data and embedded audio.
The digital video router card does not require customer alignment therefore has no user-serviceable
adjustments beyond the card edge level assign switches
7.1.3
AES digital audio router (5178)
The TX Series AES digital audio router is fitted with 24 reframing inputs and 12 regenerating
outputs. In order to promote flexible integration within any digital audio environment, modules may
be ordered for operation as balanced (110W) or unbalanced (75W).
Twelve miniature LEDs appear along the front edge of the AES router card. These LEDs are
intended for output-status monitoring and may be used to determine whether audio signal (or audio
modulation) is present on each output of the card.
There are twenty-four sets of jumper selectable pins at the rear of the module for setting the module
operating impedance. These will be factory set and are dependant upon the chosen system
configuration of either Balanced or Unbalanced audio. The following diagram shows the jumper
positioning and details the three available jumper positions.

TX 410 technical manual
LED indications
Two of the three LEDs located on the card edge indicate that power, ± 5V, is arriving on the board.
The third LED is labelled ‘HELLO’. This is useful in determining whether the control module is
communicating with a particular board and, specifically, to tell you if the LEVEL switch is set
correctly.
When the control system sends a command, for example in response to a button push, the
appropriate part of the router responds, depending on how the board configuration switches are set.
When a board receives a command on which it should act, the ‘HELLO’ LED ‘flashes’. Meaning,
‘Hello, I’ve just received a command that’s relevant to my programmed place in the system.’
7.1.5
Router control module
Central to the operation of the TX router is the control card. The card, type 2440, is a sub-module
fitted to one of the router cards within the system and is used to provide control to the router and
hold configuration data. This router level is known as the master level and is typically the Video level,
although it will work if fitted to one of the audio cards. Two default databases are supplied on disk
with the editor package, one for 525 systems and the other for 625. The relevant database will
already have been loaded into the controller before being shipped from the factory.
The TX Series router control module has two control ports available externally:
·
ROUTER CONFIG (RS232 Router Configuration port) *
·
PANEL BUS/ RS485 General Remote port.
A third, RS485, control port is wired internally to the TX Series controller for router control and
should be set for General Switcher Protocol within the database. For systems where the router is
housed in an external frame, this port is available on the remote frame and should be connected
using a ‘pin to pin’ control cable to the Remote Router port on the TX Series control frame.
The Router Configuration port permits the internal router database to be re-configured, if necessary,
while the General Remote port can be configured to support one of the following protocols:
Multi-drop Communications Protocol (SW-P-06)
·
The Multi-drop protocol, is a proprietary Pro-Bel protocol used to interface with Pro-Bel router
control panels. A single port using this protocol will support a mixture of up to sixteen Pro-Bel
control panels or undermonitor displays.
HU-TX 410T

TX 410 technical manual
Pro-Bel Ltd
General Switcher Protocol (SW-P-02) (Factory Default setting)
This protocol provides a robust, asynchronous method of controlling routing switchers. It is the
preferred method of controlling Pro-Bel routers from a system controller.
The normal electrical parameters of the interface are:
·
RS485
·
8 bit data
·
1 stop bit
·
EVEN parity
·
38.4K baud
General Remote Control Protocol (SW-P-08)
This protocol has been developed to provide a common method of interfacing Pro-Bel control
systems to a variety of standard and custom applications. It is the standard protocol for
interfacing a controller to a remote device.
* The Router Configuration port (RS232) does not support multi-drop or General Switcher
Communications protocol.

A description of the function of each of the switches is given below:
Sw2_1 Master/Slave select is used, in dual control situations, to assign Master/Slave status to the
2440 control cards. One card would be set to MASTER and the other to SLAVE so that on reset or
power up the Master 2440 powers up first and, hence, always becomes the active controller.
Sw2_2 mP clock select is used to select between 10 MHz and 20MHz mP clock frequency.
Sw2_3 System Run Mode determines which mode of operation the system powers up in (i.e.
NORMAL or TEST). NORMAL is the standard mode of operation. TEST selects a special test
mode intended for use by Pro-Bel personnel only.
Sw2_4 RS232 port select determines the function of the RS232 port. EDITOR configures the
RS232 port to be an editor port. REMOTE configures the port to be a General Remote port. For
systems using the Windows editor, this switch should always be set for REMOTE operation.
Sw2_5 Default trigger select is used to select between 625 or 525 reference to be assigned to each
source for the fixed databases. When using the editable database, the controller ignores this switch
setting.
Sw2_6 Reconfigure selects between AUTOMATIC reconfigure of cards in the system on power-up
or reset and MANUAL reconfigure where a reconfigure only occurs if manually invoked via the
terminal editor. For systems using the Windows editor, this switch must be set to AUTO.
HU-TX 410T
117
TX 410 technical manual
Pro-Bel Ltd
Sw2_7 Database Type selects whether to use the fixed, non-editable database or the editable one.
For systems using the Windows editor, this should always be set to editable database
Sw2_8 Control mode is used in conjunction with sw2_7 to select which fixed database to use.
GENERAL database configures both RS485 Remote ports to support SW-P-02 General Switcher
protocol. The PANELS option configures both RS485 Remote ports for SW-P-06 Multi-drop
Comms protocol. For the TX Series routers, using the editable database, the controller ignores this
switch setting.
Diagnostic LEDS
The 8 diagnostic LEDS fitted on the card edge provide status information for the controller as
detailed below:

The card supplies additional diagnostic information by using certain combinations of these LED’s.
4 on & 8 flashing indicates a read/ write error with the onboard RAM
4 on & 7 flashing indicates that the database is either invalid or corrupted.
For a system with an invalid or corrupt database, it is necessary to load a valid system database into
the controller. It is recommended that the system remains powered for at least 72 hours before the
module housing the controller is removed. This will ensure that the battery used to power the
battery-backed memory has been allowed to fully charge.

Router control card database editor
The TX series router control card is shared with the Freeway routing system and therefore utilises
the same database editor package. The editor with associated programs requires about 3.2 Mbytes
of hard drive space and has been designed to run on the Microsoft Windows 95 and NT4operating
systems. It can also run on Windows 2000, Me or XP operating systems. Each saved database
typically requires 1.3 Mbytes.
7.1.9
Installing the Editor
The Pro-Bel routers editor is supplied either on a CD ROM or as an e-mail attachment.
To install from CD;
Insert the CD ROM into the PC's CD drive and either:
Click 'Start', then select Run from the start menu, then type D:Setup and click OK, or
Run Explorer, view the contents of the CD ROM and select Setup.exe and follow the instructions on
screen.
An HTML help file is provided with the editor package.
To use the editor 'On-Line', the PC must have an RS 232 port capable of operating at 38.4 Kbaud
and should be connected to the ROUTER CONFIG port on the rear of the frame, using a 9 way pin
to pin cable.
Router config port
(RS 232)
Two default databases are supplied with the editor package, one for 525 systems and the
other for 625. The relevant database will already be loaded into the controller, as the
configured database, before being shipped from the factory. This database can be modified
either on or off line, using the editor, before being saved onto the PC’s hard disk.

7.1.10 Resetting the router control card
There are two RESET switches available to perform a hard reset of the controller. One is located on
the edge of the 2440 sub-module, while the other is on the front edge of the host card. Pressing
either has the same effect.
Initiating a hard reset is similar to powering down and powering up the control frame. The controller
re-boots and follows the usual power-up sequence. It should be noted that any router control panels
connected to the system will shut down, and then be restored after initialisation is complete. If no
changes have been made to the database then no crosspoints will be changed.
It is advisable to perform a reset after database parameters have been changed as certain
operations only take effect after a reset, e.g. changing level type, panel type, source overrides, and
controllable destinations. Note however that crosspoint settings may be affected if changes to the
level type have been made prior to the system reset.

8 Multi level audio
In systems requiring multi-level audio, then an audio mixer (5025), and where necessary a router
level is required for each audio level in the system. Systems using embedded audio are the
exception to this as they only require a single video router level; however independent outputs for
video and audio from the router are still required in order to permit video/ audio breakaway. Where
the audio is required to be fed to multiple audio levels, a distribution amplifier should be used to split
the signal and supply it to each mixer.
When configuring these systems, it is important to remember that the audio mixers must all be in
the same frame as they share a common control and signal bus, permitting channel swapping and
monitoring to take place. The same is also true for the internal (local) router modules as the frames
they are housed in must be interconnected by a control bus. Therefore as soon as a TX 410 system
has two or more audio levels the routing modules are removed from the main frame and are
housed in an independent frame.
Note: In multi-level systems, all of the audio mixer modules must be interconnected across the front
of the modules using a mixer card interconnect ribbon cable. In order for the panel to receive PPM
audio data from each audio mixer, the CONTROL port on all mixers should be connected, in
parallel, using a pin to pin cable back to the EXT AES MIXER port on the TX Controller. In these
systems, each audio mixer must have a unique address so that the TX Series controller can enable
the correct mixer to transmit the PPM data.

9 Saving system configurations
9.1 Configuration save/recall software
This software can be used to back up TX Series system configurations to a floppy disk or hard
drive, and is supplied with the TX System.
Before attempting to run the save/ recall programme, it is first necessary to load the programme
onto a PC, and then connect the PC to either, the TX PANEL ports (RS422) or the main system
controller card edge (front) RS 232 port
NOTE: Before attempting any TX Series system software upgrades, it is recommended that the
current system configuration be saved. This will enable the system settings to be restored if
necessary.
Configuring the hardware
The system controller can operate with the remote configuration save/ recall software by using
either:
·
The 2645 card edge port (RS232),
·
The TX PANEL ports (RS422)
When using the TX PANEL port, system configurations can be saved and recalled without the need
to remove any system modules.
To use the 2645 card edge RS232 port
·
Remove the 2645 from the main frame
·
Locate the jumper marked PL14 and set it to the TEST position
·
Connect the PC RS 232 port to the card edge 9 way D type connector using a pin to pin cable.
·
See Using the Software section below to use the program.
·
When finished using the save/ recall programme, remove the 2645, return jumper PL14 to the
NORMAL position and replace the card.

13 EMC compliance information
General
Pro-Bel equipment has been tested against the European standards EN50081-1 and -2 and
American National Standard UL1419. In all cases, the results depended on the use of the correct
cables, connectors and their correct assembly. Precautions applicable to each common signal type
are specified below. Installation provisions must be followed in order that compliance is maintained
in service. Normal practice as regards pushing cards fully home and ensuring that connectors are
well seated is essential to good EMC performance.
Digital audio connections
Cable should be of good 110W design with a foil shield. This shield must make contact all round at
the entry to the mating connector body. Pro-Bel equipment with AES3 interfaces is fitted with 'D'
type connectors and the shield is grounded to the chassis at the point of entry. The 'D' type shield
should be of the tinned type fitted with screw-locks and with dimples on the male part. Where a
number of channels use the same connector, an overall shield is preferred in addition to individual
shields and this must also be firmly grounded at both ends.
Serial digital video inputs and outputs
Cable should be good quality 75W design with double braided screens. Pro-Bel equipment with
Digital Video ('SDI' or SMPTE 259M) interfaces is fitted with BNC type connectors where the shield
is grounded to chassis at the point of entry. BNC plugs must be of the best quality as this type is
prone to EMC leakage if contact is not good all round the shell.
It is possible to improve the emissions caused by this leakage by using cables with ferrite collars.
This prevents leakage affecting adjacent cables in the installation space.
Analogue audio (including time-code)
This causes the least problem as the signal spectrum is benign and the circuit designs generally
reject most unwanted signals. Some interference could occur if the equipment contains
processors, etc.; so all screens are grounded at the point of entry. Good quality cables with foil
shields should be used with the shield carried through from end to end, and connected to the
chassis earth at the point of entry using a very short tail.
Equipment with control ports
Cable should be of good quality with a foil shield. This shield must make contact all round at the
entry to the mating connector body at both ends of the cable. Pro-Bel equipment with control
interfaces are fitted with 'D' type connectors and the shield is grounded to chassis at the point of
entry. The 'D' type shield should be of the tinned type fitted with screw-locks and with dimples on
the male part. Ribbon cables are NOT suitable under any circumstances outside of the equipment
frames.

gives ½ line delay from switch setting and each additional keyer card adds a further 1/8 line, when timed to ref.
but can be set ½ line earlier so output is only 1/8 line delayed from input.
