1 About the HDT-1000S2

The HDT-1000S2 Compact HD/SD Digital Video Transmitter is designed for short-range,
portable and fixed transmission applications and transmits remote video to a central receive
location. The HDT-1000S2 is designed to transmit up to two NTSC (or PAL) standard definition
(SD) video signals or one high-definition (HD) video signal (up to 1080i) plus two audio signals
and an RS-232 data channel. Common uses include law enforcement surveillance and video
collection.

The HDR-1000 can transmit DVB-T COFDM digital transmissions consisting of either standard
definition (SD) (NTSC or PAL) or high-definition (HD) video formats. The transmitter uses the
H.264 MPEG video compression format for high-quality imagery.

Accessories You can order an RF cable, omni antenna, and encryption license.

2 Band and Frequency of Operation

The HDT-1000S2 covers the following range:

• HDT-1000S2 S2 band 2.41—2.45 GHz (unlicensed)*

* Unlicensed operation under FCC Part 15 in S Band is factory limited to 2.414 - 2.458 GHz

This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation

3 Unpacking the HDT-1000S2

Before you install your new equipment, carefully unpack your new equipment to avoid
accidental damage.

• Locate all parts and accessories and verify that they are listed on the packing list. DO
NOT discard the container or packing material until you have inspected the equipment
and are sure there is no shipping damage. The container and packing must be available
in case you need to file a damage claim with the shipping carrier.

• Inspect the equipment for damage and that it is clean and dry.

• Inspect the cables, connectors, switches, and displays to ensure that they are not
broken, damaged, or loose.

If you discover damage after unpacking the system, report the damage as follows:

• Immediately file a claim with the shipping carrier.

• Forward a copy of the damage report to Vislink Customer Service.

Contact Vislink Customer Service to determine the disposition of the equipment.

You can connect the following cables to the HDT-1000S2.

Audio Input Audio is input to the HDT-1000S2 through the 21-pin front panel connector.

Branched cable assemblies are available for either microphone or line level
input to the HDT-1000 transmitter.

RS-232 Control You can control the HDT-1000S2 using an RS-232 command set. A branched

cable assembly is available to connect the 21-pin front panel connector to a
DB-9M connector.

Auxiliary Data You can transmit the auxiliary RS-232 data through the HDT-1000. A branched

cable assembly is available to connect the 21-pin front panel connector to a
DB-9M connector.

Video Input Video is input to the HDT-1000S2 through the front panel BNC connector. The

HDT-1000S2 accepts an NTSC or PAL analog composite signal, as well as an
ASI, or HD-SDI digital video signal. You select between analog or digital video
input using the web server software.

4 Applying Power

Power consumption for the HDT-1000S2 is 10W nominal. The following table shows the pin-out
supply voltages for the Lemo (FGGOB304CLAD52) DC INPUT connector. Vislink supplies a DC
power cable assembly with each HDT-1000S2.

the equipment.

The following guidelines for safe operation are derived from OET bulletin 65, August 1997, as
recommended by the Federal Communications Commission (FCC).

WARNING

Moderate levels of RF power are present in the unit. Exposure to RF or
microwave power can cause burns and may be harmful to health.
Remove power from the unit before disconnecting any RF cables and
before inspecting damaged cables and/or antennas. Avoid standing in
front of high gain antennas (such as a dish antenna) and never look into
the open end of a waveguide or cable where RF power may be present.

The HDT-1000S2 is a mobile transmitter. This unit, operated without an antenna, will not create
RF energy exceeding 1.0 mW/cm2, the FCC limit for exposure. Once connected to an antenna,

the potential for harmful exposure will be greatly enhanced.

In this situation, a certain distance from the radiator is to be maintained. Calculations need to be
performed to understand what that safe margin for exposure is. This is known as the Maximum
Permissible Exposure (MPE) limit.

Note

Hazardous RF radiation limits and recommended distances may vary by
country. Ensure that all applicable state and federal regulations are observed
when using this transmitter.

Calculations provided are for common antennas often utilized in the ENG environment. The
following formula used is that suggested by OET 65.

Calculating MPE

EIRP = P * (10 ^ (G / 10)) = (antilog of G/10) * P

P = RF power delivered to the antenna in mW
G = Power gain of the antenna in the direction of interest relative to an isotropic radiator
R = distance to the center of radiation of the antenna in centimeters
S = MPE in mW/cm² (milliwatts per square centimeters)

Conversions

dBi to numeric gain = Antilog (dBi/10)
Feet to centimeters = Feet * 30.48
Centimeters to Feet = cm * .0328
4 π = 12.57

User Input

RF power delivered to the antenna = Watts
Antenna gain (referenced to isotropic antenna) = dBi
Distance from the center of radiation = Feet

Calculation steps:

1. [P] RF power input. Watts to milliwatts = Watts * 1000

2. [G] Antenna gain dBi. Numeric gain = Antilog (dBi/10)

3. [EIRP] Multiply P * G

4. [R] Centimeters to feet = Centimeters * .0328

5. Square R

6. Multiply R² * 4π

7. [S] Divide (R² * 4π) into EIRP

S = Power Density in milliwatts per square centimeters.

Note

At frequencies above 1500 MHz, S must not be greater than 1.
