The TCM2.5 is a drop-in replacement for PNI’s original TCM2 family of products. It offers improved accuracy and performance for compass heading, tilt and magnetometer measurements. It is the same size, has the same 10-pin RS-232 interface connector and is completely backwards compatible with the original TCM2 ASCII protocol. These features make the TCM2.5 the choice for existing applications that require compatibility the TCM2 family of products. The TCM2.5 integrates 3-axis magnetic field sensing, 2-axis tilt sensing and compass heading into a single module. Advantages include compatibility with existing systems, low power consumption, large signal noise immunity under all conditions, and a large magnetic field measurement range. The TCM2.5 combines PNI Corporations’s patented MagnetoInductive (MI) magnetic sensors and a MEMS accelerometer for unparalleled cost effectiveness and performance. MI sensors change inductance by 100% over the wide field measurement range. This variable inductance property is used in a cost and space efficient ASIC, incorporating a temperature and noise stabilized oscillator/counter circuit which is inherently free from offset drift. Applications • ROV/AUV’s Features • High accuracy compass heading: 0.8º • High resolution compass heading: 0.1º • High repeatability: 0.1º • Wide tilt range: +/- 50º • Multiple measurement modes: compass heading, magnetic field and 2-axis tilt • Calibrated magnetic field measurement range: +/- 80 µT (+/- 0.8 Gauss) • High resolution magnetic field measurement: 0.05 µT (0.0005 Gauss) • Reliable calibration: hard-iron calibration with quality of calibration score • Low Power: < 20 mA typical current draw • Backwards compatible digital interface: RS-232 • Backwards compatible footprint: TCM2 hole spacing * The TCM2.5 was designed as a transitional product to replace the original TCM2 family. For any new applications, the TCM2.6 is highly recommended. • Remote terrestrial antenna direction indicators • Side-scan sonar • Survey equipment Ordering Information • Robotics systems NAME • Vehicle detection TCM2.5 Module 12413 • Buoys TCM2.5 Interface Kit 90011 TCM2.5 Evaluation Kit 90018 PART NUMBER Interface kit includes: module, manual, evaluation software and 18” pigtail cable Evaluation kit includes: module, manual, evaluation software, 18” pigtail cable and 6ft finished DB-9 cable with power supply Developed by America’s premier sensor technology company.
