Operational lives for TVIT models are calculated using Telonics Product Programmer (TPP), with assumptions of 60 beats per minute and operation 24-hours per day at 30°C.

Key Features

  • Retention "wings" serve to prevent expulsion until parturition.
  • Units include MS6 mortality-motion sensor option to signal parturition and mark the site.
  • These models typically use Telonics MK-12 electronics, but can use the MK-11 electronics. Both versions are microprocessor controlled and can be programmed using Telonics Product Programmer (TPP). The MK-11 has synthesized frequencies programmed through TPP; the MK-12 is crystal controlled. The MK-12 is most frequently used in smaller configurations because it provides longer life (particularly at temperatures of ~0°C or below).
  • Transmission power levels are selectable to accommodate either greater range or greater life.
  • Customized transmission duty cycling (on/off periods) is available, including seasonal cycles which can vary throughout the life of the transmitter.
  • All timing is controlled by a Real-Time-Clock, which allows seasons to start and end on any desired calendar date and time, and sensor data to be accurately time stamped.
  • Other sensor options are available, including the MA activity option, MS4 temperature option, and MS5 temperature-triggered mortality option (sensor descriptions are provided below).
  • Data Logging Option 350 is available to store mortality, activity, and/or temperature data in transmitter memory for download if the transmitter can be recovered.

Data Logging Option (Option 350)

The Data Logging Option for MK-11 and MK-12 transmitters (Option 350) allows sensor data from the MS6 mortality-motion sensor, MA activity sensor, and/or the MS4 temperature sensor to be stored in transmitter memory and made available for download if the transmitter is able to be retrieved at the end of a study. Additional information regarding how these sensors work is provided in the Sensor Options section below. This option requires use of Telonics Data Converter to download the stored data.

For the MS6 motion-mortality sensor, the data logging records each date and time the sensor switches from active/alive to inactive/mortality or back. Assuming that no other sensor measurements are being stored, the data log can accommodate about 0.5 million transitions. Note that smaller units may not have sufficient battery capacity to fill the memory. The most recent 9-16 such transitions are recorded even without this option, but this option stores all such transitions.

For the MA activity sensor, the data logging option stores accelerometer data at user-defined intervals. These intervals may be the same throughout the anticipated life of the transmitter or they may change "seasonally". The activity data recorded is the number of active seconds (or other defined classification interval) during a defined collection interval. For example the number of active seconds in a one hour collection interval would be saved as a number between 0-3600. Assuming that no other sensor measurements are being stored, the data log can accommodate about 2.0 million measurements based on 30sec, 1 minute, or 5 minute intervals or about 1.3 million based on longer intervals. The activity collection schedule for data logging is independent of any activity schedule selected to control pulse rate.

For the MS4 temperature sensor, the data logging option stores temperature data at user-defined intervals (in 0.16°C increments). These intervals may be the same throughout the anticipated life of the transmitter or they may change "seasonally". The data log can store an estimated 1.3 million measurements if no other sensor data are stored. The temperature collection schedule for data logging is independent of any temperature schedule selected to control pulse rate.

Specifications for Transmitter Electronics

MK11/12 Transmitter General Specifications

MK-11 and MK-12 beacons are microprocessor controlled pulsed-CW transmitters, designed for operation within the 137 - 225 MHz frequency range. Each MK-11 beacon transmits on a single, field-programmable frequency (within the frequency range that is ordered). MK-11 beacons also support 3 field-programmable power levels. The MK-12 beacon is crystal based, and therefore each beacon is built to operate on a specific frequency and with a specific power output (four power levels to choose from when ordering).

Warranty: VHF Transmitting Subsystems

The VHF Transmitting Subsystem includes the following main components: internal digital and radio frequency electronics comprising the transmitter, power supply (battery), exterior packaging, transmitting antenna and attachment. A refurbished Subsystem is warranted as if the Subsystem was purchased new, unless otherwise stated.

Telonics warranties only the following with respect to the Subsystem:
1.1 The internal electronics (excluding batteries) are warranted to be free from defects in materials and workmanship and to perform to the operational specifications over the specified operating temperature range as published by Telonics for the rated operational life of the Subsystem (as recorded on the final test data sheet accompanying the unit), up to a maximum of three (3) years from the date of initial shipment of the Subsystem by Telonics.
1.2 The exterior packaging integrity of hermetically sealed subsystems are warranted for the full operational life of the Subsystem, up to a maximum of three (3) years from the date of initial shipment of the Subsystem by Telonics.
1.3 The exterior packaging integrity of polymerically sealed subsystems are warranted for the operational life of the Subsystem, up to a maximum of one (1) year from the date of initial shipment of the Subsystem by Telonics.

Limitations:
Although each Subsystem is supplied with a power supply in the form of a battery, Telonics does not manufacture batteries (electrochemical cells), and therefore cannot warranty the battery lifespan, mechanical integrity or other battery performance issues. However, Telonics conducts extensive testing of all types of electro-chemical subsystems to determine suitability to the application. Once an electrochemical system is chosen for a configuration, testing procedures are employed at Telonics to evaluate every individual battery that is installed in each transmitting subsystem. Even using these advanced testing procedures it is not possible to determine a specific battery's lifespan or mechanical integrity.

Telonics conducts tests to assure that each unit is transmitting at the power level selected by the user. Actual range performance is a system characteristic dependent upon numerous conditions including receiver sensitivity and noise figure, receiving antenna tuning and pattern, transmitter antenna integrity, line of sight conditions in the field, and vegetation and habitat conditions and other factors specific to individual study sites. Therefore it is not possible to warranty a minimum range that will be achieved for units deployed in the field.

"Packaging integrity" as applicable to 1.2 and 1.3 above, is limited to normal wear as encountered on the animal.

It is the purchaser's obligation to make certain that it orders the correct size and type of Subsystem for the particular type and size of animal that the Subsystem will be applied to, and no warranty is expressed or implied for any failure to meet operational specifications due in whole or in part to use of an incorrect size or type of Subsystem.

No warranty is expressed or implied with regard to abnormal events or damage due to human actions such as gunshot damage, vehicle encounters, etc. Further, no warranty is expressed or implied with regard to damage resulting from misuse, accidents, unauthorized service, extreme conditions, or other causes not specifically enumerated herein.

The entire risk, as to the results and performance of the Subsystem, is assumed by the customer. Neither Telonics, nor its suppliers, shall have any liability to the customer or any other person or entity for any indirect, incidental, special, or consequential damage whatsoever, regardless whether Telonics has been told of the possibility of such damages or that such damages might be foreseeable. Telonics has no responsibility or liability for the claims of any third party. Telonics' and its suppliers' maximum aggregate liability shall not exceed the amount paid by the customer for the Subsystem.
