VHF Transmitter Option Descriptions

Opt. MS6 Mortality-Motion Sensor. Provides "active or alive" or "inactive or dead" pulse period depending on activity state of the study animal. A motion-sensitive switch is incorporated in the unit to detect animal movements. The microprocessor continuously monitors the motion switch to determine when motion occurs. Once per second, the microprocessor increments an "activity counter" if motion was detected during the preceding one-second time period. This "activity counter" keeps a running total of the number of times motion was detected over a user-programmable mortality evaluation time (128 sec to 6 days). The active pulse period is maintained as long as the number of switch closures in the mortality evaluation time is greater than the mortality threshold. If the number of switch closures falls below the established threshold, the unit produces the inactive period. A separate resurrection threshold allows the unit to return to the active pulse period. If the number of activity counts during the evaluation interval exceeds the resurrection threshold, the unit will immediately assume the active pulse period. Notes:
The microprocessor updates the "inactive" pulse period at intervals of 1/16th of the evaluation interval. This means that the actual time between cessation of motion and initiation of the "inactive/dead" pulse period could be up to 6.25% longer than the evaluation period.

Opt. MS9 Tip Switch Sensor. Transmits one of two different pulse rates depending on orientation of transmitter. Usually designed to switch pulse rates as it passes through an angle of 0° (parallel to horizontal). Other switching angles may be selected with some configurations (factory set within 10°).** Typical uses include monitoring "head "up" and "head down" positions. Note:
The MK9 transmitter integrates the time spent "head up" vs "head down" with ~0.5sec time constant. If the transmitter position changes rapidly with respect to the integration time constant, the resulting pulse period will be between the "head up" and "head down" pulse period, providing an indication of the average amount of time the transmitter spent in the two positions.

Opt. MDC MK9 Duty Cycles. Transmitters can be programmed for up to eight sequential time periods or "seasons", generally used to extend transmitter life. During each season, the transmitter may be "enabled" or "disabled". Timing is controlled by a Real-Time-Clock, allowing seasons to start and end on any desired calendar date and time, regardless of when the transmitter is initialized. Once the transmitter enters the last programmed "season", it continues to operate under the last season's parameters for the duration of the transmitter's lifetime.
Within each season, the transmitter may be programmed with an on/off "duty cycle" to further extend transmitter lifetime. Each on/off cycle can be defined in one hour increments from 1 hour to 255 hours (about 10.6 days).

Service Commitment

Since 1970, Telonics has built a reputation based on product quality, product support, service, and customer satisfaction. Telonics strives to produce the highest quality products, and to support those products accordingly.

Because of extreme conditions and the unpredictable nature associated with most telemetry applications, problems occasionally arise. Most problems can be resolved quickly. In all cases, we hope to be able to work in partnership with users to resolve problems to the user's satisfaction and to uphold our demonstrated commitment to excellence. If problems should arise, all products must be returned to our factory for failure analysis.
