Component Operations

Transmitter

The transmitter unit is mounted in the van 

(guidelines should be referenced here)

 and

connected to the antenna. Place the antenna on top of the van or truck preferably in the
center of the roof of the vehicle. When transmitting, the unit will send a series of carrier
bursts at the factory set frequency (27.45, 27.47, 27.49 MHz) radiated at 5W through the
antenna. If the bursts ingress into the house, the Qualifier unit will measure the signal, then
display its relevance to the internal threshold (

See Qualifier component)

.

The transmitter is controlled by the Qualifier via the means of a Command Link, which is
activated when the “Q” is pressed after putting the Qualifier unit in 

Qualifier Mode.

 This

allows the Qualifier unit to command the transmitter when to send its carrier.

Elements of the transmitter device are:

Receiver User Identifier (RUID) Rotary Switch

The RUID Rotary switch has 0-F possible values. This allows a transmitter to transmit only
from Qualifier units that send this RUID in the command link transmission. This would
allow more than one transmitter and Qualifier units to service a neighborhood without
interference from one another.

Power Light (Green)

After powering the transmitter, this light will illuminate after the unit has finished internal
initialization and determined that no current fault modes are active. If a current fault is
active, this light will not illuminate.

TX Light (Yellow)

When the unit receives a command from a Qualifier unit to transmit, this light will activate
during the transmission to confirm the Command Link is functional and a signal has been
radiated.
