INTRODUCTION
The HD-3500 Series of stand-alone SMPTE 3G video High
Definition Serial Digital Interface (HD-SDI) with audio and data
transport systems extends the range limits of electrical interfaces,
and combines audio and data along with the HD-SDI signal in a
single optical fiber link. The system will transport digital signals
from 5 Mbps up to 2.970 Gbps, analog audio, AES digital audio,
serial data, intercom, tally, and General Purpose I/O (GPIO)
signals.
Applications include transmission links for high definition or
digital television, studio to transmitter; studio-to-studio, robotic
studio cameras, studio to CATV head-end and back-haul feeds
from special events. The transmitter and receiver units are
available in portable or stand-alone and modular configurations
ideal for both field and studio applications.
FEATURES & OPERATION
The HD-3500 supports all popular standards for digital video
transport such as SMPTE 259M-C, SMPTE 292M, and SMPTE
424, working at 270 Mbps, 1.495 Gbps, and 2.970 Gbps
respectively. In addition, the HD-SDI interface also will transport
signals compatible with DVB/ASI, and SMPTE 297M interfaces at
the defined rates. The units include a digital reclocked DA and
repeater for the SMPTE SDI standards mentioned above. For
other standards and rates, the signal is automatically or manually
passed thru without reclocking. For the SDI/HD-SDI input, the
units include automatic cable equalization based on the data rate
detected.
Separate from the SMPTE video transport, the HD-3500 also
transports 4 analog audio channels with maximum configurable
levels of 4dBu, 10dBu, 16dBu, or 28 dBu; 2 digital AES pairs
up to 96Khz that cross convert with the 4 analog channels;
and a bidirectional stereo channel for intercom applications
with maximum level of 4dBu. The system also supports 4 GPIO
bidirectional channels with open collector inputs capability and
relay contact for the outputs; 1 bidirectional tally IO with open
collector input and contact relay output; and 3 bidirectional serial
data channels compatible with RS232 or RS422 transport up to
3Mbps.
To accomplish SMPTE video with bidirectional audio and data
transport, 3 wavelengths are multiplexed over a single fiber
using a CWDM module, a 1310nm optic used for SMPTE video,
and 1490nm and 1550nm optics are used for the bidirectional
audio and data transport. The SMPTE video input and output use
standard BNC connectors while the audio and data use a DB44
connector with either a special breakout cable assembly or a
diving board. See appendix A for pin-out information.
A Gigabit Ethernet and Sync Transport option is available, HD-
3500-GE-TX and HD-3500-GE-RX, which adds a copper to fiber
Ethernet media converter to each unit and a reference sync
transport from the Rx unit to the Tx unit. Rates of 10/100/1000
Mbps are supported for Ethernet and supported sync formats are
NTSC, PAL, and HD Tri-Level.
TRANSMITTER, HD-3500-FTX
The transmitter module front and back is shown in figure 1. In the
back and from left to right it includes a DB44 connector for all
audio and data IO; two serial digital video SMPTE 75 Ohm input
BNC connectors, one for input and one for reclocked SDI / HD-
SDI output loop; a single fiber output ST or SC connector; and a
DC Jack power connector. In the front of the module we see 3
SMPTE SDI lock LEDs for 270 Mbps, 1.485 Gbps and 2.970 Gbps
rates; SMPTE SDI CD (Carrier Detect) LED; 2 audio status LED that
indicate channel 1 and 2 level, peak, or AES presence; 6 data
activity LEDs to indicate TX and RX activity in the 3 data channels;
a tally on indicator LED; a link status LED; and a power LED.
SMPTE video transport
The HD-3500-TX receives SMPTE video or other properly
encoded data signals from 5Mbps to 3Gbps. The SMPTE video
signal is connected to the 75 ohms BNC input connector in
the back. Signals with rates from 19 Mbps to 3Gbps are then
equalized. Equalization The HD-3500-TX receives SMPTE
video or other properly encoded data signals from 5Mbps
to 3Gbps. The SMPTE video signal is connected to the 75
ohms BNC input connector in the back. Signals with rates
from 19 Mbps to 3Gbps are then equalized. Equalization is
used to help open the digital video eye pattern that may
have been closed or deteriorated due to long coaxial cable
runs. After equalization, the signal is reclocked and sent to
Figure 1. Front and Back of HD-3500-FTX
1INTRODUCTION Instruction Manual, HD-3500 Series

the fiber transport and to a 75-ohm loop output, which is the second BNC connector in the back. The front rate LEDs indicate that a valid
SMPTE rate is locked by the re-clocker PLL. The Carrier Detect (CD) LED indicates that a signal has been applied to the input. Carrier
Detect is sensitive to digital carriers from 19Mbps to 3Gbps.
Non-SMPTE transport via the SMPTE interface
The HD-3500 will operate normally by default with SMPTE video signals at the rates indicated earlier; however, other signals may need
special settings. The SMPTE video input has a feature that automatically mutes signals as noise or other signals under 19Mbps. If you
need to transport these signals, the auto mute feature can be disabled changing the jumper J10 from the 1-2 to the 2-3 position, see
figure 2 with default setting. Non-SMPTE standard signals should automatically put the reclocker into bypass mode; however, in some
instances, if the signal has components close to the SMPTE frequencies, there may be glitches on the operation. To void this, there is
another jumper, J5 that when inserted will force the reclocker into bypass mode. The default setting for J5 is open as shown below.

Instruction Manual, HD-3500 Series FEATURES & OPERATION 2

Audio Transport
This unit can transport two balanced stereo pairs (4 monos), or two AES channels of high quality audio. The unit automatically detects
if AES audio is present in each channel to be selected, otherwise the corresponding analog stereo pair is selected. The AES channels
can be set for 110 ohms balanced input mode or 75 Ohms singled ended input (see table 1). The analog stereo pairs can be set for
dierent full scale (FS) levels using a dip switch, 600 ohms input mode, or +6dB compensation (see tables 2 and 3). The audio LEDs
indicate three possible statuses: constant blinking green indicates AES signal is present, green indicates analog level is present with a
level from -8dBFS to -1dBFS, and red indicates clipping. Even if a tiny clip is detected, the red LED is held for a fraction of a second. In
addition to these main audio channels, there is a bidirectional stereo channel for intercom applications. This channel has unbalanced
inputs, and a maximum audio range of +4dBuFSv
Data and GPIO Transport
This link includes three bi-directional asynchronous data channels that can transport signals up to 3 Mbps. These channels can be set
with RS232 or RS422 levels by setting a switch, see table 1. In addition, there are four GPIO bidirectional channels and, a Tally with a
front indicator. The General Purpose Input interface can be controlled with a short to ground (open collector), 3.3V, or 5V TTL levels.
The General Purpose Output is an internal relay contact to ground that can safely switch up to 48V and up to 2A signal.

3 FEATURES & OPERATION Instruction Manual, HD-3500 Series

Gigabit Ethernet and Sync Option
Reference Transport
The Gigabit Ethernet & Sync option, HD-3500-GE-TX, will output
a reference genlock signal supplied by the HD-3500-GE-RX
unit. Only the sync portion of the reference signal is transported
across the fiber link, all video and color information is stripped
from the signal. Supported formats include SD Black Burst (NTSC,
PAL) and HD Tri-Level.
Ethernet Transport
The Gigabit Ethernet & Sync option, HD-3500-GE-TX, includes
a copper to fiber Ethernet media converter. Data rates of
10/100/1000 Mbps are supported.
RECEIVER, HD-3500-FRX
The receiver module front and back is shown in figure 3. In the
back and from left to right it includes: a DB44 connector for all
audio and data IO, two SMPTE serial digital video 75 Ohm output
BNC connectors for two reclocked SDI / HD-SDI outputs, a single
fiber output ST or SC connector, and a DC Jack power connector.
In the front of the module we see three SMPTE lock LEDs for 270
Mbps, 1.485 Gbps, or 2.970 Gbps rates; Fiber Signal Detector
LED. Also included are 2 audio status LED that indicate channel
1 and 2 level and peak; 6 data activity LEDs to indicate TX and
RX activity in the 3 data channels; a tally on indicator LED; a link
status LED; and a power LED.
SMPTE transport
The HD-3500-RX receives the SMPTE video or other high-speed
signals multiplexed along with audio and data from the fiber
connector. These signals are optically de-multiplexed, and then
sent to a reclocker to clean high frequency jitter created by
return loss and fiber interfaces. The signals are then buered
and sent to the two 75-Ohm outputs with BNC connectors in the
rear of the unit. Like in the TX side, the re-clocking capabilities
work automatically when SMPTE rates are detected. The front
rate LEDs indicate that a valid SMPTE video rate is locked by the
re-clocker PLL. The Signal Detector (SD) LED indicates that a light
signal has been applied to the optical interface and status. If the
LED lights red, it means that the signal is heavily attenuated;
typically less than -21dBm, there is nothing active connected
on the fiber port, or the fiber is broken. A yellow light means
the optical power is attenuated, typically less than -17dBm, but
the link is still is operative probably due to a long run of fiber or
attenuation in the path.
Non-SMPTE transport via the SMPTE interface
This unit should work normally by default with SMPTE video
signals at the rates indicated previously; however, other signals
may need special settings. The reclocker will mute the output
when noise or a not supported SMPTE rate is detected. This
feature can be disabled when using other rates by setting SW4
on the PCB. Non-SMPTE standard signals should automatically
put the reclocker in bypass mode; however, in some instances,
if the signal has components close to the SMPTE frequencies,
there may be glitches on the operation. To avoid this, there is
another setting for SW4 to force the reclocker into bypass mode.
See table 4 for SW4 settings.
Audio Transport
This link transports two balanced stereo pairs, or two AES
channels of high quality audio. In the RX side, for each stereo
pair, and whatever signal either analog or digital was selected
at the TX side, is sent simultaneously to the analog and digital
AES ports. This feature eectively can convert an analog signal
in the TX side to digital in the RX side, or the reverse case. The
AES channels can be set for 110 ohms balanced output mode or
75 Ohms singled ended output (see table 5). On the other hand,
the analog stereo pairs can be set for dierent Full Scale (FS)
levels using a dip switch (see table 6). The audio LEDs in the RX
side indicate two possible statuses: green indicates analog level
is present with a level from -8dBFS to -1dBFS, and red indicates
clipping. Even if a tiny clip is detected, the red LED isheld for a
fraction of a second. In addition to these main audio channels,
there is a bidirectionalstereo channel for intercom applications.
This channel has unbalanced inputs, and a maximumaudio range
of +4dBuFS.

Data and GPIO Transport
As introduced earlier, this link includes three bi-directional asynchronous data channels. These channels can be set with RS232 or
RS422 levels by setting a switch, see table 7 for the selections in the RX side. These selections are independent from those in the TX
side of the link allowing translation between RS-232 and RS-422 devices if needed. As in the TX side, we have the same four GPIO
bidirectional channels and, a Tally with a front indicator in the RX side. Read the TX section of this manual for more information on GPIO.

Gigabit Ethernet and Sync Option
Reference Transport
The Gigabit Ethernet & Sync option, HD-3500-GE-RX, will send a
reference genlock signal to the HD-3500-GE-TX unit. Two BNC’s
are provided, one for the input and the other as a loop-thru
output. The reference signal must be terminated with a 75 ohm
terminator, either on the loop output BNC or at the end of the
loop if multiple units are being daisy chained together.
Only the sync portion of the reference signal is transported
across the fiber link, all video and color information is stripped
from the signal. Supported formats include SD Black Burst (NTSC,
PAL) and HD Tri-Level.
Ethernet Transport
The Gigabit Ethernet & Sync option, HD-3500-GE-RX, includes
a copper to fiber Ethernet media converter. Data rates of
10/100/1000 Mbps are supported.
Changing the Data Format (Mezzanine board only exists when
ordered without Gig Ethernet and Sync Option)
To change the settings on the SW1 - SW4 main board follow the
steps below and refer to Table 4 - Table 7 for dierent operation
settings;
1. Open Topside cover by carefully removing all 6 screws and
placing all aside for re-assembly after formatting Data settings.
2. Place unit onto flat surface facing away from you so that
all of the inputs on backside are facing towards you. Remove
panel on your lefthand side to fully expose both the Top and Main
board inside as shown below.
3. SW1 - SW4 is located on the Main/Bottom as shown below.
4. Position the HD-3500 opened box so that it is facing to your
left with all rear ports facing to your right. Set the SW1 (Position 1)
to the OFF position (towards you is ON and away from you is OFF).
SW1 should be positioned to OFF like below once completed.
5. Once the SW1 switch has been set to “OFF” you can replace
the side panel and screw top securely into place with all 6 screws.
POWER REQUIREMENTS
The HD-3500 Series operates from 110 or 220 VAC with the
included wall-mount 12V power supply or other source in a
range from 9 to 24 VDC and at least 25W of power. It uses a
coaxial type connector (sleeve ground) on the rear panel labeled
POWER. If desired, the units can be powered from a battery pack
or automotive battery instead of the wall unit.
INSTALLATION
The installation and start up of the HD-3500 Series does not have
special requirements. No special sequence must be followed to
connect and start up the unit. RG59 or other 75 Ohms Coax cable
must be used for the SDI inputs and outputs, and single mode
fiber with the proper connectors must be used for the fiber link.
Multimode fiber cannot be used reliably with the HD-3500. The
HD-3500 Series come standard as stand-alone units. An optional
rack-mounting kit is available to mount up to 3 units in a 1 Rack-
unit or 1 ¾” by 19” rack space. The part number is –RMT.
