XM3 Transmitters

These cylindrically shaped units are housed in a brass case for maximum durability. They can be setup as implants (snakes), backpacks (large birds), bolt-on (turtles), or collar-style (small mammals), and customized to meet your exact requirements.

Specifications – Implant Setup

^ The addition of the duty-cycling option can greatly increase the lifespan.

Specifications – Backpack/Bolt-on Setup

^ The addition of the duty-cycling option can greatly increase the lifespan.
* The addition of the tubes will increase the overall length.

Specifications – Collar Setup

^ The addition of the duty-cycling option can greatly increase the lifespan.

Pulse Width (standard): 24 milliseconds (ms). Available from 18-32ms.

Pulse Rate (standard): 40 pulses per minute (ppm). Available from 5-120ppm.

Housing: The battery and transmitter are hermetically sealed in a brass case. For the implant setup, the case is coated with multiple layers of a biologically inert butyl rubber compound and a small groove is added to allow for suturing.

Attachment: A number of mounting options are available (see photos above). Implant: no mounting setup, Backpack: a brass tube is attached at each end for either a Teflon ribbon or cable harness. Bolt-on: brass tabs are attached at the mid-point or at the ends for screw attachment. Collar: the unit is attached to a 9mm wide neoprene-impregnated polyester collar fastened with a self-locking nut and captive stud.

Antenna: Stranded stainless steel cable covered with a black nylon coating. One or two layers of shrinkable tubing reinforce the antenna at its base.

Activation: Holding a magnet next to the unit starts the transmitter. Passing it over again stops it.

Options

Available for an additional charge. Multiple sensors can be added to a single unit.

Mortality (suffix “M”): There are two options for this mode:
–Standard (faster): After a preset period (1 to 24 hours) of no movement, the pulse rate changes to an INCREASED rate or a DOUBLE pulse, to indicate mortality. After this mode has been triggered, any motion resets the transmitter to the normal pulse rate. Locking mortality is also an option, when you do not want the unit to exit mortality mode once initially triggered.
–Reverse (slower): After a preset period (1 to 24 hours) of no movement, the pulse rate changes to a DECREASED rate, to indicate inactivity (torpor, dormancy, hibernation), greatly extending the lifespan. After this mode has been triggered, any motion resets the transmitter to the normal pulse rate.

Activity (suffix “A”): After a preset motion sensitivity or angle has been reached, the pulse rate will change (to an increased rate OR a double pulse) to indicate real-time movement. When the movement stops, the pulse rate returns to its normal rate.

Temperature (suffix “T”): An increase or decrease in temperature results in a corresponding increase or decrease in pulse rate. The high and low temperature limits are set by the user (0-50C), as is the pulse rate (5-120ppm) at each extreme. Each transmitter is supplied with a plotted calibration curve.

Duty Cycling (suffix “D”): To conserve battery power and extend the lifespan, the transmitter can be programmed to enter low-power mode each day (from 1-23 hours). During this low-power mode, the unit can be silent (0ppm) or programmed to pulse at a greatly reduced rate (4, 6, or 8ppm).
