Description
The HD2300 is a high quality converter that
accepts high definition video and outputs standard
definition video. Is it designed specifically to
provide all the quality and the facilities that
broadcasters need in a compact 2RU enclosure.
Here is all the Snell & Wilcox technical pedigree
packaged to give exactly what broadcasters via
satellite, cable or over the air, need to use HD
originals, from tape, disk or directly from
contribution feeds, on air and looking good in an
SD format.
Operation is straightforward and fuss free leaving
the HD2300 to do all the work. Also there are
essential features that add to reliability, such as
dual redundant power supplies and RollCall
remote monitoring and control. Besides converting
the video, other aspects such as audio and closed
captions are all handled in line with broadcast
requirements.
The video converter itself makes use of the latest
Snell & Wilcox technology to deliver the highest
quality conversion for Broadcasters. The input
accepts any HD format on HD-SDI and the output
can be set to 525/60 or 625/50 digital video TV
broadcast standard of the same frame/field rate
and available as SDI. The advanced video
processing means that the output pictures have
excellent sharpness..

Installation
UNPACKING THE HD2300
The unit is packed in a single carton. The contents
of the carton are as follows:
1 HD2300 unit
1 Power cable
2 Spare a.c. power fuses 3.15 A (T)
1 HD2300 Installation and Operating Manual
1 Generic Power Supply Installation Manual
Unpack the carton carefully and check for any
shortages or shipping damage. Immediately report
any shortages or damage to Snell and Wilcox
Limited. (see front page section 0)
POWER CONNECTIONS
Power Supply
Mains power is supplied to the unit via two filtered
IEC connectors. The upper connector is for the
PSU installed in the upper position and the lower
connector is for the PSU in the lower position.
Caution! This unit is designed to function
with both power supplies operating.
TO REDUCE THE RISK OF ELECTRIC
SHOCK, PLUG EACH POWER SUPPLY INTO
SEPARATE BRANCH CIRCUITS EMPLOYING
SEPARATE SERVICE GROUNDS.
The mains power rating is 2.5A maximum from
100V to 250V.
Two Snell & Wilcox generic power supply modules
type SHDPSUA15 are fitted. The HD2300 does
not have a monitoring system; the operation of the
LED indicators on the front panel of the module
are described in the manual for the power supply.
The power supply ON/OFF switches are located
on the front of the power supplies inside the front
panel.
Supply Voltage
The power supplies are auto switching for input
voltages in the ranges of 100 V to 250 V nominal.
No voltage adjustment procedure is required.
CAUTION: THIS UNIT MUST NOT BE
OPERATED WITHOUT AN EARTH
CONNECTION.
CAUTION: THE FAN EXIT VENTILATION
HOLES AT THE SIDE AND REAR OF THE
UNIT MUST NOT BE OBSCURED.

Environment
Although ruggedly constructed to meet the normal
environmental requirements, it is important that
there is a free flow of air at the front, left-hand side
(looking from the front) and rear to dissipate the
heat produced during operation. Installations
should be designed to allow for this.
Remote Control
The unit may be controlled via the RollCall remote
control system from an active front panel or a PC
running the RollCall Control Panel software.
OPENING THE FRONT PANEL
Open the front panel by Turning the black knob at
the right-hand end a half-turn anti-clockwise and
then hinging the panel open to the left.
The rack mount fixing “ears” are revealed when
the panel is open.
Refit the front panel by hinging it back into position
and turning the black retaining knob.

INPUT CONNECTIONS
All the connectors are mounted on the rear panel
of the unit and are appropriately annotated.
HD Serial Digital Inputs
These are the two inputs (A and B) for HD SDI
input signals.
Genlock Reference Ref A and Ref B
External HD trisync or SD bi-sync analogue
reference signals may be connected to either
(REF A or REF B) of these two loop-through BNC
connectors.
AES Audio Input
Four external stereo channels can be input for
embedding in the HD output.
3:2 Flag
These connectors have no function on this unit.
Do not make connections to these items.

OUTPUT CONNECTIONS
SD SDI Output
Three BNC connectors provide identical SD SDI
outputs.
AES Audio Output
The four AES audio outputs are available from
these connectors.
HD/SD Output
These connectors have no function on this unit.
Do not make connections to these items.
Composite Output
These connectors have no function on this unit.
Do not make connections to these items.

COMMUNICATION CONNECTIONS
RollCall
The unit can be controlled via RollCall using the
BNC connector or the RS-422 9-way D-type
connector.
The RollCall BNC system should be connected
using 75 Ohm "T" pieces in a similar manner to an
"Ethernet" system. Both extremities of the system
must be terminated in 75 Ohms.
A unique address for each unit on the RollCall
system must be set by two Hex switches (SW1,
SW3) on the printed circuit board. The addresses
00 and FF are reserved and must not be used.
Hex Switches
Both of these switches are used to define the Unit
Address code for the equipment. They are only
read at power-up.
All positions on these switches may be used to set
the Unit Address code in Hex (0 to F).
Notes: In a RollCall™ segment, all units must
have different unit address codes. For more
information see RollCall™ section.
The coaxial link is bi-directional and therefore must
not be passed through signal switching networks.
Also, to allow hum and noise cancellation the
screen of the coaxial connection must not be
earthed.

GPI Overview
The GPI provides contact closure tally outputs that
can be used to turn on lamps etc.
The equivalent circuit of the GPI input is shown on
the next page.
Note. On a standard machine when delivered, GPI
inputs 0 to 5 select machine memories 1 to 6 and
GPI outputs 0 to 5 provide tally outputs indicating
which memory is selected.
The GPI port is polled approximately 2ms after the
vertical sync group of either the input or the output
video. This is determined by the Comms Locking
mode - see the Setup–Comms menu item in the
Operations Section of this manual for further
information.
Note. For interlaced output standards the polling
occurs at field rate and for progressive output
standards it occurs at frame rate.
