Description
Normal operation for the transmitter is to receive, process and transmit via RF frequencies, data from various types of attached
ground sensors. The transmitter frequency is selectable via synthesizer control circuits providing a selection of up to 1920 RF
channels, depending on frequency range, to choose from:
Low Band Mid Band High Band
Channel 001 = 138.025 MHz Channel 001 = 154.005 MHz Channel 001 = 162.00625 MHz
Channel 600 = 153.000 MHz Channel 1600 = 162.000 MHz Channel 1920 = 174.000 MHz
Design Features:
 ID Code Selection 001-999
 Internal power ON – normal operation – antenna up
 Internal power OFF – non operating – battery cap up
 Internal power ON – align (sensor set) – battery cap down
 Transmit ID Code Alarms
 Transmit State-Of-Health-Messages
 Directional information (L>R, R>L)
 Sensor fault (when both are on at the same time)
 Tamper
 Test
 Low Battery
 Three switches for programming operation functions
 A Tri colored LED used to confirm programming process functions
 A sealed battery compartment
 An RS-232 data port for interfacing with a computer
 Potted and sealed electronic components
 Injection molded plastic housing
 Metal battery cap clamps with heat welded screw inserts
 Frequency matched antenna
During normal operation the transmitter may be triggered by an external sensor through its sensor connection. A message will
then be transmitted on a selected channel. A message may also be initiated with the push button on the top unit. The unit may
be put in the align mode by placing it with the battery cap down. Power is turned off by placing the unit with the battery cap
up. Power will remain on for five minutes after it is initially applied.
