INTRODUCTION
The HD3500 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 backhaul
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 and OPERATION
The HD3500 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.
Figure 1. Front and Back of HD-3500-FTX
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 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 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 HD3500 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

Instruction Manual, HD-3500 Series FEATURES and OPERATION 3
REV G, March 17, 2017
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.
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 different 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 +4dBuFS

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.

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.
Figure 4. Front and Back of HD-3500-FRX
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 buffered 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.

REV G, March 17, 2017
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.
Table 4. 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
effectively 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 different
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 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 amaximum
audio 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.

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.
