Rear Panel View
The ARC130S is a compact Broadcast-Quality
Aspect Ratio Converter with serial digital inputs
and outputs. It will aspect ratio convert in both
directions, e.g. 16:9 to 4:3 or 4:3 to 16:9, and
allows the picture area required for transmission to
be selected from the input picture.
There are twelve preset conversion ratios plus
ratios set up by the user. The user ratios can be
stored in twelve memories and are quickly
pushbutton selected when required for use.
The aspect ratio can also be remotely controlled
either via an RS-422 port, RollCall or from contact
closures via a General Purpose Interface (GPI).
The ARC130S is designed to fit in Continuity
Suites, Studio’s, Outside Broadcast Vans, etc.
It facilitates the production of master tapes for
broadcast using PAL+, D2MAC and digital
transmissions. It facilitates postproduction and
presentation of tapes mastered in 16:9 format
through the current 4:3 format transmission
system.
The ARC130S is a compact 1RU high unit for
location on the desktop or in a 19-in. rack. It will
operate in 525 and 625 line systems.
Vertical interval information is passed without
conversion.

POWER CONNECTIONS
Power Supply
Mains power is supplied to the unit via a filtered
IEC connector with integral fuse holder. The fuse
rating is 2.5 A (T).
The unit automatically senses the supply voltage in
the ranges 90V-132V and 176V-264V and sets
itself up accordingly. No voltage adjustment
procedure is required.
ENVIRONMENT
The unit is ruggedly constructed to meet the
normal environmental requirements. It is important
that there is a free flow of air at both sides of the
unit to dissipate the heat produced during
operation. Installations should be designed to allow
for this.
If the unit is to be rack mounted, first open the front
panel by lifting up the the two levers at right and left
of the panel, hinge the panel down and

pull it forward. The fixing “ears” behind the panel
will be revealed and the unit can be mounted in the
rack. Refit or close the front panel by pushing it
back into position (the levers will click into place).
The rear of the base includes additional fixing
holes on either side to allow a rear support to be
added.

ARC130S SECTION 3
Installation
ARC130S 060801 Version 1 Issue 1 3.3
Delay Output
Because the ARC130S contains a synchroniser,
the through delay depends upon the setting of
vertical genlock timing.
If the input and output video are co-timed, then the
delay through the ARC130S is four fields (80 ms
for 625 line systems and 66.7 ms for 525 line
systems). If the input and output video are not co-
timed then the range of delay through the ARC is
3.5 to 4.5 fields.
The delay pulse output from the ARC130S
accurately represents the delay through the unit.
The pulse is high for a period equal to the delay
through the ARC. It can be connected to a Snell
and Wilcox audio delay module to automatically set
a compensating audio delay.
If the ARC130S is put into Bypass mode or, field
pairing mode, then the nominal delay remains at
four fields. However because the unit acts as a
frame synchroniser in these modes, the delay
range of the unit is now increased to between 3
and 5 fields.

OPERATION FROM A KUDOS ACTIVE FRONT PANEL FITTED TO A SHOEBOX
OPERATIONAL OVERVIEW
The ARC130S has provision to be remotely
controlled via two different interfaces, either S&W
RollCall, or RS422.
Interface to the "RollCall" communications network
is via the single BNC connector. Connections
should be made by means of a `T' piece (Zo=75
Ohms) to a 75 Ohm cable system as shown below.
It should be noted that both extremities of the cable
system must be terminated in 75 Ohms and the
maximum number of units limited to 240 on one
single cable run.
The communications network is a specially
designed remote control network system and many
more units can be accommodated by using a
"Network Bridge". Remote control can come from
either a dedicated front panel or "shoe-box" or a
standard IBM compatible PC. Full protocol
documentation and more detailed information is
available on request from the supplier.
The RS 422 remote control interface is via the 9-
pin female `D' connector. Protocol information is
also available on request from the supplier.
For more detailed information about the operation
of the remote panel or PC software please consult
their relevant manuals. e.g. Shoebox operator’s
manual.
For specific information about the RollCall menu
system for the ARC130S see Section 4, Operation,
RollCall Menu System on page 4.34
BASIC ROLLCALL OPERATION
All the features from the menu system are
available remotely with the same options structure.
This maintains compatibility and facilitates easy
operation for users familiar with the unit.
The most common remote configuration is shown
below where many units are connected to the
network for remote control by one remote panel or
"shoe-box".
Typical Set-up
The network address for the ARC is set using the
switches SW3 and SW4 on the Output Interface
card. See fig 3.1 on page 3.8.
Parameter changes are reflected both locally and
remotely. For example, if the output is changed to
the colour bars test pattern by a remote unit then
any further access from the card edge to the
PATTERN TYPE option will indicate this change.
Similarly, if the card edge changes a parameter
then this will be reflected on the display panel of
the remote unit.

ARC130S SECTION 3
Installation
ARC130S 060801 Version 1 Issue 1 3.7
GPI Overview
The GPO provides contact closure tally outputs
that can be used to turn on lamps etc.
GPO 0 tracks GPI 0 so if the display memory that
GPI 0 recalls is active then GPO 0 will close.
Similarly, GPO 1 tracks GPI 1 etc.
This functions even if the GPI inputs have been
assigned different recall memories and if the
memory was recalled via a front panel button
rather than via the GPI.
So, if GPI 3 recalls AUTO, then whenever AUTO is
selected GPO 3 will be closed.
In GPI binary mode, the four LSB’s (GPO 0 to
GPO 3) GPI contacts indicate the binary GPI
memory in use. The four MSB’s (GPO 4 to GPO 7)
contacts are closed if a GPI binary memory is
being used; otherwise they are open.
If a non-binary GPI memory is being used all 8
contacts will be open.
GPI interface Delay
The GPI interface on the ARC130S has a delay
that matches the video processing delay through
the ARC.
This means that if a given input-video field is
desired to produce the first output-field built with a
new aspect ratio conversion; the GPI contacts that
recall that new aspect ratio conversion should be
closed during the field when that video field is
present at the ARC130S input.
Ideally, the contact should be closed a few lines
after the vertical sync group of the reference video,
and, should remain closed for at least one field
period.

ARC130S SECTION 3
Installation
ARC130S 060801 Version 1 Issue 1 3.8
Included with ARC130S software version A32 are 2 floppy disks containing software for up and down
loading ARC configurations to a PC.
ARC Configuration Loader Program
The downloading and uploading of ARC
configuration files is made possible by the
Windows program ‘ARC Configuration Loader’.
Data contained in existing ARC configuration files
(held on the PC) may be downloaded to the ARC
or, ARC hardware configurations may be uploaded
to the PC. The configuration files held on the PC
are in a simple ASCII text format. The
configuration files contain all parameters held in
the ARC. This includes all display memories of all
types that the user can program. This allows the
user to configure an ARC once and then, send that
same configuration to multiple units. Also, if the
ARC software is upgraded, the user can store the
ARC configuration before the upgrade and then
download it afterwards so that the configuration
does not have to be re-done.
The ARC Loader program uses the ARC RollCall
network BNC connection. Thus, the user must
have a means of connecting to the ARC RollCall
BNC before the program can be used. Therefore a
RollCall ‘Shoebox’ or a PC equipped with the high
speed RollCall network card must be available.
The ARC loader program is designed to work with
ARC software version A28 and onwards. Note that
software versions A24 and onwards allow the user
to upload the configuration data from the ARC to
the PC but, the download operation can fail. This
will allow users of software versions A24 to A27 to
capture their ARC configurations before upgrading
to A28.
ARC Configuration Loader Installation
The distribution of the ARC Configuration Loader
includes a setup.exe program file. This file is kept
on the floppy disk labelled DISK1. Running the
ARC Configuration Loader setup.exe, either by
mouse click from within Windows Explorer, or from
the Windows Start\Run menu, will commence the
setup sequence. SETUP SHOULD ONLY BE RUN
LOCALLY TO THE TARGET HOST MACHINE,
this may be achieved either by installing locally
from floppy disk or, by copying the installation files
to a local, temporary directory and running setup
from there. The ARC Configuration Loader
requires the RollCall server program RollOLE to be
pre-installed. The ARC Configuration Loader setup
program searches for a registered installation of
RollOLE prior to commencing its own installation
sequence. If the RollOLE executable is found and
validated then ARC Configuration Loader will
install. Conversely, if setup is unable to find or
validate RollOLE.exe it will inform the operator of
the requirement to install, or re-install, RollOLE and
then setup will exit. The installation of RollOLE
should then be carried out before re-attempting to
run the ARC Configuration Loader setup program.
A compatibility issue has arisen in that RollOLE
makes use of Windows Dynamic Link Library (.dll)
files, the current RollOLE is compatible with the
Library files required to run Internet Explorer (IE)
4.0 or later. Earlier versions of RollOLE will not run
correctly on systems that have installed on them
IE4.0, conversely, the current version of RollOLE
cannot run using the .dll files found on a system
using IE3.x or earlier. The setup program will
therefore detect the absence of IE, or if present the
version of IE, and may accordingly give the
operator the option to continue to load the ARC
Configuration Loader, or exit if a configuration not
suited to RollOLE is detected. This is only an issue
for systems running Win95, as Win98 and
WinNT4.0 implicitly use IE4.0 or later.

ARC Configuration Loader Operation
The ARC Configuration Loader program can be
run by double clicking on it from Explorer or via the
START menu. When the program is run the User
needs to set two parameters and then up and
downloading may begin.
1. Configuration File Name
This is the name of the file on the PC that the user
wishes to access. If an Upload is undertaken then
the data from the ARC will be stored in this file. If a
Download is undertaken then data from this file will
be sent to the ARC. A valid filename must be
chosen before an Upload or Download can be
undertaken. Note, the file extension must be .TXT.
The filename can be typed in or, the Browse button
may be used to navigate to the desired file.
2. ARC Address
This allows the user to select which ARC on the
RollCall network the program will connect to. The
user must select an ARC before an Upload or
Download can be undertaken. The find module
button should be clicked to navigate to the desired
unit.
3. Download
Clicking this button will send a configuration file
from the PC to the chosen ARC.
4. Upload
Clicking this button will send configuration data
from the ARC to the selected PC file.
Program Menu Selections
The following Menu selections are available to
operators of the ARC Configuration Loader:

panel by lifting up the levers at right and left of the
panel, hinge the panel down and pull it forward.
To provide a full range of functions with just 4
buttons and an 8-digit display, a menu system is
used.
During normal operation, the display slowly cycles
through the status of current operation (Home
Display). Typically these will be the line standard,
the aspect ratio, genlock status and pattern
generated if on.
The ENT (Enter) key interrupts the Home Display
and allows you to enter the menu structure. It is
also used to display a selected option. The and
keys enable you to scroll up and down through
the menu. The ESC (Escape) key returns you to
the previous menu level.
A “>“ at the right of an option on display indicates
that selecting the option (pressing ENT) will lead to
another menu level without changing a system
setting. If there is not a “>“ at the right, pressing
ENT will change the indicated system setting.
If the menu being displayed allows you to pick one
of a number of options, the currently selected
option is indicated by an “∗” (asterisk) at the left.

parameter to it’s preset value.
Pressing ENT and ESC simultaneously will return
you to the Home Display.
