Regulatory Statements Industry Canada Notice to Users Operation is subject to the following two conditions: (1) This device may not cause interference and (2) This device must accept any interference, including interference that may cause undesired operation of the device. See RSS-GEN 7.1.5 FCC Notice to Users Magna Systems has not approved any changes or modifications to the ThermoSpyder made by the user. Antenna modification, antenna replacement or use of an antenna not approved by Magna Systems is not authorized. Any changes or modifications could void the user’s authority to operate this equipment. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio / TV technician for help. Battery Disposal Please do not throw batteries in the trash. Used batteries must be disposed of in accordance with local regulation. For information about how to recycle batteries in your area, visit the Rechargeable Battery Recycling Corporation (RBRC©) at www.rbrc.org. Rev. A iii Important Safety Information Electrical Shock Hazard There are no hazardous voltages present in the ThermoSpyder, however the American National Standards Institute (ANSI) states that a shock hazard exists when probes or sensors are exposed to voltages greater than 42 VDC or 42 V peak AC. In some applications thermocouples may be attached to objects or surfaces between which voltages in excess of the ANSI shock hazard standard exist. Despite the electrical isolation designed into the thermocouple assemblies, conditions may exist such that hazardous voltages could be present at the dual row connector of the thermocouple assembly. In such cases, users must handle the dual row connector of the thermocouple assembly in a manner consistent with the presence of hazardous voltages. Exposure to Radio Frequency (RF) Energy The ThermoSpyder contains a radio transmitter and receiver. Whenever powered, the ThermoSpyder will receive and emit radio frequency energy. The ThermoSpyder is designed to comply with local regulatory requirements including those concerned with the exposure of human beings to RF energy. Use of Rechargeable Batteries Under conditions of heavy use it may be advantageous to use rechargeable batteries to power the ThermoSpyder. Most rechargeable batteries, due to the chemical recombination process within the batteries, will vent non-corrosive gases to the ambient atmosphere. Ensure that the ThermoSpyder is used with adequate ventilation when rechargeable batteries are used. Explosive Environments DO NOT USE THE ThermoSpyder IN EXPLOSIVE ENVIRONMENTS. Areas with potentially explosive atmospheres are often, but not always, posted. Such areas may include, but are not limited to, fueling areas, enclosed areas where fumes may accumulate (such as below decks on boats or areas near poorly ventilated gas powered appliances), chemical transfer or storage areas, laboratories, and areas when there are airborne particulates such as grain, dust, aerosolized paints or fine metal powders. DO NOT USE THE ThermoSpyder IN SUCH AREAS. The installation or removal of batteries may cause sparks which could cause an explosion or fire. Not …

The transceiver is a true single-chip RF communications solution which requires a minimum number of external components. Communications and control of the transceiver is affected via digital interface signals from the microcontroller unit (MCU). A block diagram of the radio frequency section is shown below.

The use of a transmit / receive switch reduces power consumption during transmission at high output power levels and also improved receiver sensitivity. The switch is controlled by digital signals from the transceiver chip. The simplified transceiver block diagram is reproduced from the manufacturer’s datasheet. The manufacturer’s datasheet provides a discussion of the architecture and features of the transceiver as well as instructions for design of circuitry and operation of devices utilizing the CC1020.

To make a measurement, the microcontroller unit selects the desired thermocouple by sending control signals to the channel selector switch. The switch connects the selected thermocouple across the inputs of the differential amplifier. This low-noise, zero-drift amplifier magnifies the relatively small thermocouple voltage such that an effective measurement can be made. The amplified voltage is presented to the input of the analog to digital converter where it is converted to a digital code. The digital code is read by the microcontroller unit and stored in memory. In order to interpret the digital code representing the thermocouple temperature correctly, the “cold” junction voltage must be compensated. The ThermoSpyder uses an integrated circuit temperature sensor to accurately measure the “cold” junction temperature and the microcontroller then performs software based compensation. The microcontroller then selects the next channel to be measured and the process is repeated as required. The radio transceiver is used to periodically transfer acquired temperature data to DataLink using the GateWay network access node. If, for any reason, the data is not transferred to DataLink, the ThermoSpyder stores the data in the flash memory and transmits the data later.
