Technalogix Ltd. TM-100 Modulator

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.
