TRANSMITTER OPERATION
A. HOW TO SETUP THE TRANSMITTER
1. LOCATON
The Transmitter is designed to be mounted against a flat surface for
support and stability. The Transmitter is not weatherproof and should be
mounted in an environmental enclosure if used outdoors or in a harsh
environment.
2. POWER
The MiniLink is powered by a 6-14.5 VDC power supply connected to
the Power In connector on the rear of the case of the directional
transmitter or the 4 pin plug of the omni-directional transmitter. The
transmitter incorporates internal reverse voltage protection.
3. CHANNEL SELECT
Channel selection is accomplished by programming of the 4-position
dipswitch located at the rear panel of the directional transmitter and on
the front of the omni-directional transmitter. Switch and frequency
settings are listed on the label below the switch access.
4. AUDIO SELECT
Audio mode selection is enabled by programming the 2-position
dipswitch located at the rear panel of the directional transmitter and on
the front of the omni-directional transmitter. Switch settings are listed on
the label adjacent to the switch access.
The Audio In connector can be used for either line or microphone input
levels. If an electret microphone is used, the second switch position can
be selected to supply +5 V to the electret element. The +5V microphone
supply should be disabled for dynamic microphone or line input uses.
5. ORDER OF SETUP AND OPERATION
• Select Frequency and Audio mode. (Factory set to channel 10)
• Connect Power, Video and Audio inputs to transmitter.
• Position transmitter for desired polarity using rear label arrow as a
reference, transmitter and receiver polarity must match one another.
B. MAINTENANCE
Your MicroTek Electronics product is an example of superior design and
craftsmanship. Use the system only within the environmental
specifications indicated. High temperatures can shorten the life of
electronic devices and melt plastic parts. Excessive mechanical shock can
damage the case, connectors or internal circuit board.
