Introduction The Self-Calibrating Auditory Tone Infrared (SCATIR) Switch is a multipurpose momentary-contact optical switch with auditory feedback designed for use by persons who experience difficulty in activating mechanical switches. It works by detecting a beam of reflected pulsed infrared light. It is suitable for use with a variety of movements, including eye-blink, eyebrow movement, finger movement, head movement or facial muscle movement.
Description 1. Front of Sensor Box Relay Out: Plug the relay cable into this port. It connects directly to the device you want to control. Relay On: This green light is on as long as the relay is closed/switch closure occurs. Valid: The valid light flashes three times when the unit is turned on, when the dip switches are changed or the mode is set. To Sensor: The end of the sensor plugs into this port. Mode/Status: Flashes when switch closure occurs.
2. Back of Sensor Box 12/24 VDC: Plug the 12V charger into this port to charge the internal 9V rechargeable battery. Battery: This is a rechargeable 9 volt battery that has been installed for you.
3. Bottom of Sensor Box Dip Switches: These switches are used to control the tone, the sound of the tone and the calibration mode. Set Switch: This recessed switch is used when setting the manual calibration.
Operation 1. Dip Switches On the bottom of the unit you will find 4 dip switches or four small white switches. These switches are used to control the tone, the sound of the tone and the calibration. Up is on. Down is off. Beep On Beep Off Continuous Tone Beep Tone Manual Calibration Self Calibration SW1 SW1 SW2 SW2 SW3 SW4 SW3 SW4 Up Down Up Down Up Down Down Up 2.
3. Self Calibrating Mode When the switch is being activated by a body part that cannot always maintain a constant activation distance from the sensor, the switch can be operated in self calibrating mode. In this mode, placing the activating body part at ANY given distance within range of the switch will serve to define that distance as the activation distance. Once activated at this distance, the switch may be turned off by moving the body part completely out of the range of the sensor.
4. Manual Calibrating Mode When in manual calibrating mode, the activation distance is set by the user. 1. Turn the sensor box off. 2. Set the dip switches to: SW3 SW4 Up Down 3. Position the sensor. 4. Place the activating body part just beyond the desired activation distance. 5. Turn the sensor box on. 6. Press the set switch beside the Dip Switches with the end of a pencil until you hear three beeps and the valid light flashes three times. 7. The manual calibrating mode is now set.
5. Auditory Tone The switch incorporates an auditory tone which emits a beep when the switch is activated. This auditory feedback can be enabled or disabled by means of a dip switch. The user can select either of two auditory feedback modes: Beep Tone Mode: A short momentary beep is emitted to indicate activation. The relay light remains on throughout the full period of activation. Continuous Tone Mode: A tone is emitted which lasts as long as the switch is activated.
Power Rechargeable Battery To recharge the Nickel Metal Hydride (Ni/MH) battery in the SCATIR switch, plug the power unit into the charger jack labeled “12-24 VDC” on the back of the SCATIR switch. The yellow LED on the front of the box lights up to indicate that the charging current is going into the battery. The charging time for a fully discharged battery is 8 hours with the SCATIR switch turned on or off. Do not attempt to charge non-rechargeable batteries.
Mounting 1. Gooseneck Mounting Option The SCATIR switch gooseneck sensor is equipped with a standard 5/8 – 27 thread. The kit comes with a variety of clamps and couplers to assist you in mounting the gooseneck. The kit includes: • • • • • • • ABS Plastic Mounting Plate Adhesive-backed Velcro ® Quick Release Gooseneck Mount assembly X-saddle Self Tapping Screws (#10, 1 inch long, Phillips, flat head) Band Clamp Multi-bit Screw Driver For more mounting information please go to this site: http://www.msu.
2. Eyeglass Mounting Option This kit comes with the sensor clamped in a typical position on a set of eyeglass frames. The eyeglass mounting may need to be adjusted to make it work well for the individual user. The kit includes: - Two Allen wrenches (5/64”) - Polyurethane bushings - Sensor Clamp assembly, including two-part polished stainless steel clamp, socket head cap screws (2-56), polyurethane bushing and polyurethane protective grommets.
The angled-head sensor is constructed so that the wire leads and the plastic insulation may be bent. Imbedded in the right-angle sensor is soft wire that helps the sensor to stay in position after bending. This permits easy adjustment for pointing the sensor towards the body part that is used for operation of the SCATIR switch. The sensor head may be re-angled by simply grasping the end of the sensor and pushing and bending it into place.
