Safety and First Aid
Personnel engaged in the installation, operation, maintenance, or servicing of electronic
equipment are exposed to the hazard of high voltage. It is imperative that all safety
regulations and precautions are consistently observed.
Knowledge of first aid
procedures is recommended. The following information is presented as a reference
only.
•
At all times, avoid placing any part of the body in series between ground and circuit
points, whether power is on or off.
•
Dangerous voltage may be present in equipment even though power is off. Do not
open the cabinet. Refer servicing to qualified service personnel.
•
It is the duty of all personnel to be prepared to give adequate emergency first aid
treatment and thereby prevent avoidable loss of life.
•
There are three principle degrees of burns, recognizable as follows:
• a first-degree burn reddens the skin.
• a second-degree burn blisters the skin.
• a third degree burn chars the flesh and frequently places the victim in a state of
shock accompanied by respiratory paralysis.
•
Respiratory paralysis can cause death by suffocation within seconds.
It is
imperative that the approved methods of artificial respiration are initiated
immediately and continue until the victim’s breathing is normal.
•
A muscular spasm of unconsciousness may render the victim unable to break free of
the electric power. If this is the case, turn the power off immediately.
DO NOT TOUCH THE VICTIM OR YOU MAY SHARE THE SAME
PREDICAMENT.
•
If the power cannot be turned off immediately, very carefully loop a dry rope, article
of clothing, length of strong cloth or a rolled-up newspaper around the victim and pull
the victim free of the power source. Carefully avoid touching the victim or clothing.
•
Once free of the power source, the victim must be placed in a reclining position and
covered with a blanket or newspapers to keep warm. At the first opportunity, enlist
help in summoning a doctor. If a doctor cannot be summoned, transport the victim
to the doctor or a hospital. Be sure the victim is kept well covered and warm while
awaiting professional treatment.

3.0 D ESCRIPTION AND SPECIFICATIONS
General Description
The high output modulator eliminates the need for preamplifiers prior to the
power amplifier system. The modulator processes baseband audio and video
information to provide an IF output consisting of a visual IF carrier at 45.75 MHz,
using amplitude modulation, and an aural IF carrier at 41.25 MHz, using
frequency modulation. An internal upconverter translates the modulator circuitry’s
IF carriers to VHF and UHF television frequencies. All operating controls are
located on the front panel, as described in a later section. An aural loop through
is provided to properly set transmitter power.

Video Conditioning Module
The TM-100 modulator includes a separate circuit board called the Video
Conditioning Module. The baseband video signal passes into the modulator,
through a group delay filter, and onto the video conditioning Module circuit board.
This module accomplishes two processes:
1. Sync Stretch. Allows the user to adjust the sync level to maintain the
proper level. Adjustment is made via potentionmeter VR2 and can be
made through the ventilation holes in the modulator lid without having to
remove the lid. Potentionmeter VR1 adjusts the video modulation level
and must be made by either removing the lid and adjusting VR1 or by the
Video Modulation adjust on the front panel of the modulator. The sync
stretch is powered by +5Vdc brought in to the connector and –5Vdc,
which is generated on board by U1.
2. Video Detect. Turns off the 24Vdc supply to the final amplifier in the TM100 in the event of missing video input. The power supply for the final
amplifier (+24Vdc) is routed through a relay on the circuit board. In the
event of a missing video signal, the relay contact is opened and the
+24Vdc is disconnected from the final amplifier.
The input and output impedance of the Video Conditioning Module is 75-ohms
and video connections are made via RCA connectors. The video Conditioning
Module can be bypassed, if necessary

4.0 INSTALLATION
This section contains installation recommendations, unpacking, inspection, and
installation instructions for the Technalogix TM-100 Modulator. Carefully read all
material in this section prior to installation. Also read and review operating
procedures later in this section.
Building Recommendations
The quality of the building is of great importance if you are to expect long life and
continued performance from the modulator. The building must be clean, dry,
temperature controlled and secure. The modulator takes up a single 1-U high
space on a 19” rack. Don’t forget to allow space in the building for any additional
racks to house test equipment, a workbench area, line regulating transformers,
ladders, equipment and parts storage, first aid kit, emergency generator if used,
as well as heating and cooling devices that may be unique to your installation. A
sloping roof will tend to develop leaks less rapidly. The building should be well
roofed with good material. The cooling load will be lowered with reflective or light
colored roofing material.
Heating and Cooling Requirements
The environment’s temperature will contribute greatly to the length of the
modulator’s life. Technalogix recommends that the building’s filtered air intake
must have capacity for all air-flow in the building plus an additional 20%. Keep
the intake below the roofline to avoid intake of solar heated air. Please ensure
that the intake and exhaust areas are on the same side of the building to avoid
pressure differentials during windy conditions. Also, do not position intake near
exhaust’s preheated air. If air conditioning is required to cool the shelter, discuss
the situation with a qualified HVAC technician. Under average conditions, 12,000
BTUs will cool approximately 500 square feet to a comfortable level.
Technalogix Ltd.
TM-100 Modulator
Electrical Service Recommendations
Technalogix recommends that a qualified, licensed local electrician be consulted
for the required electrical service. We suggest local electricians because:
• The personnel knows the local codes
• The personnel can be on site readily
• You are apt to get better overall support if you give what business you can
to local suppliers
Technalogix recommends that proper AC line conditioning and surge
suppression be provided on the primary AC input to the power amplifier. All
electrical service should be installed with your national electrical code in your
area, any applicable provincial or state codes, and good engineering practice.
Special consideration should be given to lightning protection of all systems in
view of the vulnerability of most transmitter sites to lightning. Lightning arrestors
are recommended in the service entrance. Straight and short grounds are
recommended. The electrical serviced must be well grounded. Do not connect
the unit to an open delta primary power supply, as voltage fluctuations could
harm the unit. Branch your circuits. Do not allow your lights, your workbench
plugs, and your transmitting or translating equipment off of one circuit breaker.
Each transmitter should have its own circuit breaker, so a failure in one does not
shut off the whole installation.
Antenna and Tower Recommendations
Your preliminary engineering workgroup should establish your antenna and tower
requirements, both for receiving and transmitting antennas. Construction of
sturdy, high quality antenna/tower systems will pay off in terms of coverage of
your service area, the overall quality and saleability of your radiated signal, and
reduced maintenance expenses. Technalogix provides complete turnkey antenna
systems if needed. Transmitting antennas can enhance or seriously impair the
transmitter output. It is assumed that one has been selected prior to system
installation, but the best-designed antenna system will function poorly if shortcuts
and compromises are used during installation. Follow the manufacturer’s
instructions exactly, along with any engineering data prepared for the site.
Technalogix Ltd.
10
TM-100 Modulator
The selection, routing, and length of coaxial cable is extremely important in the
installation. If there is a 3 dB line loss in the cable between your unit’s output and
the transmitting antenna, a 500 watt unit will only deliver 250 watts to the
antenna. Buy the best cable you can obtain, route it via the shortest way to the
antenna, and keep it straight. Do not form it into sharp bends on its way. Do not
use any more cable fittings for the installation than absolutely necessary. All
cautions here apply equally to all coaxial cables in the system - input and output.
The better known tower manufacturers offer complete technical and safety
documentation with their towers. Be sure that you have this information as it
regards wind loading, guying, etc. Be absolutely safe and certain about this
aspect as human lives may be at stake.
Shelter Security
The FCC requires that the transmitter be secure from entry or control by
unauthorized persons, and that any hazardous voltages or other dangers
(including most tower bases) be protected by locks or fences as necessary to
protect personnel and prevent unauthorized tampering or operation. Security of
the building further implies that it be secure from wildlife. Use sturdy construction
materials, including sheet metal if necessary. Holes around conduit, cable, and
other similar entry points should be stuffed with steel wool and caulked to prevent
entry of wildlife. Other features of security for your shelter may include its location
with respect to the prevailing wind conditions. A location leeward of some natural
topographical feature will prevent wind damage and snowdrifts. Check the soil
runoff conditions that may slow or hasten wind or water erosion and other
concerns that may be unique to your location.
Technalogix Ltd.
11
TM-100 Modulator
Unpacking and Inspection
Check the outside of the container. Carefully open the container and remove the
modulator. Retain all packing material that can be reassembled in the event that
the equipment must be returned to the factory.
Exercise care in handling equipment during inspection to prevent
damage due to rough or careless handling.
Visually inspect the enclosure of the modulator for damage that may have
occurred during shipment. Check for evidence of water damage, bent or warped
chassis, loose screws or nuts, or extraneous packing material in connectors.
Inspect all connectors for bent connector pins. If the equipment is damaged, a
claim should be filed with the carrier once the extent of the damage is assessed.
Technalogix cannot stress too strongly the importance of immediate careful
inspection of the equipment and subsequent immediate filing of the necessary
claims against the carrier if necessary. If possible, inspect the equipment in the
presence of the delivery person. If the equipment is damaged, the carrier is your
first area of recourse. If the equipment is damaged and must be returned to the
factory, phone for a return authorization. Claims for loss or damage may not be
withheld from any payment to Technalogix, nor may any payment due be
withheld pending the outcome thereof. Technalogix cannot guarantee the
carrier’s performance.

Important
Technalogix power supplies are designed so that under certain power line or
heat buildup conditions, the unit shuts off. An indicator would be no RF output,
but the POWER LED remains on. If this occurs, unplug the power cord and wait
two minutes before re-powering. Upon applying power, you should again have
RF output. If not, or should the unit return to shutdown mode, please contact
Technalogix for assistance. Technalogix highly recommends a 1.75 inch air
circulation space between any rack mounted equipment.
Transmitter Hookup
1. Connect modulated video from TM-100 RF OUT to the Technalogix power
amplifier.
2. Turn down RF level on TM-100 all the way.
3. Ensure that IF OUT is connected to IF IN on the TM-100 modulator using the
loop F to F cable supplied.
4. Connect the transmitting antenna cable to the RF output connector on the
power amplifier. It is recommended that a quality through line wattmeter be
installed in this same line.
5. Verify that all signal and RF cables are connected properly.
6. After following proper installation procedures outlined in the power amplifier
manual, plug the power amplifier’s power cords into an appropriate electrical
outlet.
Output power should be adjusted with a sync and blanking signal only with the aural
carrier removed. This is simply done by disconnecting one end of the audio carrier loop
found on the back panel of the TM-100.

6.0 P ROBLEM T ROUBLESHOOTING GUIDE
The guide below covers some typical symptoms, possible associated causes and
suggested actions to follow before returning the unit for repair. It is not meant to be allinclusive.
Symptom
Possible Cause
Suggested Action
No output
Weak output
Unit tuned to output channel different from desired
(this occurs particularly on the units which have
green LED on the front panel to indicate “T”
channels and channels above 99)
Ensure selected output channel is
desired channel
Input signal is too weak
Ensure input signal strength is 1V
peak to peak
IF loop cable on rear of unit loose/disconnected
Check IF loop cable is securely
attached
Unit not plugged in or not getting power
Check power cord and power
source, fuse
Output level above rated maximum (most often
occurs when changing from high-number channel to
low-number channel, especially to the “T” channels)
Measure RF output from rear
panel jack and adjust front panel
OUTPUT LEVEL control as
required
IF level too high (most often occurs when routing IF
through scrambler or other external device)
Measure normal IF output level
for applied CW/unmodulated
input carrier and ensure same
level is returned to unit after
external processing
Input signal too strong or no input signal at all
Measure video level and pad to
within specified input levels.
Bad/noisy video
Aural carrier interfering with video carrier
Measure Aural Carrier level
and/or adjust AURAL CARRIER
LEVEL control on front panel
Channels do not
change
Delay feature active
Hold channel change switch in
raised/lowered position for at
least three seconds
Excessive noise
Spurious signals
