The function of the CTS Series 120 TrackPak™ integrated pointing device module is to measure force applied to the top of the pointing stick’s rubber cap by a user’s finger, process the input, and output a mouse signal to the host computer. The Series 120 TrackPak™ assembly uses the CTS’ patented ceramic pointing device sensor as its user interface. CTS SERIES 120 SPECIFICATION 1843-40 1. SENSOR CHARACTERISTICS 1.1. The sensor has a ceramic post with mutually perpendicular X, Y, and Z axes, with the origin located at a point along the stick axis 1 mm below the top of the rubber cap. 1.2. All forces are assumed to be true force vectors (no torques). 1.3. For axes polarity reference: 1.3.1. X Positive – to the right of keyboard 1.3.2. Y Positive – to the top of keyboard (away from user) 1.3.3. Z Negative – down into the keyboard 2. WORKING RANGE 2.1.1. XY Working Range – 0 grams to 320 grams 2.1.2. Z Working Range – 0 grams to 500 grams 3. HORIZONTAL OUTPUT 3.1.1. A horizontal (X/Y) force between 10g and 320g applied to the pointing stick will result in a horizontal output of 1 count per 0.8 grams of applied force. 3.1.2. The positive X-axis shall lie within 10° of the direction to the right along the line of the keys. © 2003 CTS CORPORATION. ALL RIGHTS RESERVED. INFORMATION SUBJECT TO CHANGE SERIES 120 PRODUCT SPECIFICATION CTS PART NUMBER: 1843-40 4. OCTOBER 22, 2003 DOC#MPS184340 PAGE 5 OF 10 VERTICAL OUTPUT 4.1.1. A 500-gram vertical force applied uniformly to the top of the rubber cap will result in a target Z output of 50 counts. 4.1.2. The positive Z-axis shall lie within 10° of the normal to the place of the keyboard. 5. DYNAMIC RESPONSE 5.1.1. In response to an instantaneous change in force within the working range an output shall reach within 2 counts of its final value within .2 seconds. 5.1.2. In response to an instantaneous change in force within the working range an output shall reach within 1 count of its final value within .5 seconds. 5.1.3. Outputs shall not overshoot by more than 1 count at any time. ELECTRICAL SPECIFICATIONS 6. SUPPLY VOLTAGE REQUIREMENTS 6.1.1. Vcc = 5VDC ± 10% 6.1.2. Vss = 0V 6.1.3. Peak to peak differential noise and ripple on +5V line shall be less than 100 mV. 6.1.4. At power on/off the TrackPak™ shall withstand a voltage overshoot of Vcc + 30% or a voltage undershoot of Vss - .5V. 7. POWER CONSUMPTION REQUIREMENTS 7.1.1. Current drain is typically <3mA. MECHANICAL SPECIFICATIONS 8. OVERLOAD 8.1. Horizontal Overload 8.1.1. The pointing device shall withstand a 4.0 ± .1 Kg horizontal load applied perpendicular to each face of the ceramic post at a location within .5 mm of the top of © 2003 CTS CORPORATION.

All physical and electrical specifications shall be met after horizontal overload. 8.2. Vertical Overload 8.2.1. The pointing device shall withstand a 20 Kg vertical load applied to the top of the rubber cap parallel to the axis of the ceramic post. All physical and electrical specifications shall be met after vertical overload. 9. LIFE 9.1. Horizontal Life 9.1.1. The TrackPak™ assembly shall withstand 10,000,000 cycles of horizontal deflection at a peak force of 250 Grams applied to the top of the pointing stick, perpendicular to the axis of the ceramic post. The radial angle of the load shall be varied continuously by a rotating arm. One cycle consists of 360° rotation at a speed of 3000 revolutions per minute. All physical and electrical specifications shall be met after horizontal cycle life testing. 9.2. Vertical Life 9.2.1. The TrackPak™ assembly shall withstand 10,000,000 cycles of vertical deflection at a peak force of 400 grams applied to the top of the pointing stick parallel to the axis of the ceramic post. One cycle consists of zero grams applied ramping to 400 grams peak and back down to zero grams. All physical and electrical specifications shall be met after vertical cycle life testing. 10. VIBRATION AND SHOCK 10.1.1. The TrackPak™ assembly shall withstand a 20 gram, 10Hz – 20Hz, vibration for a duration of four hours in each plane. 10.1.2. The TrackPak™ assembly shall withstand three 100 gram, 1 millisecond, shocks in each plane. E N V I RO N M E N TA L S P E C I F I C A T I O N S 11.
