FCC ID: M5ZWOWInstallation and Operation Instructions for the Wireless Temperature Sensor.Point Six, Inc.Wireless Temperature SensorModel WOWInstallation and Operation InstructionsThe WOW wireless temperature sensor transmits both a digital temperature and a unique serialnumber to a 418 MHz receiver. The WOW is enclosed in a high impact ABS enclosure fordirect surface mounting in the environment to be measured. WOW is battery operatedApplication: Apply the sensor to the surface to be monitored with double-sided adhesive tape.Make sure that the side labeled with FCC ID is visible and away from any metal surfaces.Service Function: The wireless temperature sensor has an installation mode switch. Amomentary push of this switch will start the convert/transmit cycles. When new and until thisbutton is pushed the WOW will not transmit. The WOW will transmit a special installationstatus mark in the data packet immediately after the installation/start switch is pushed. After thestart a push of the installation switch will result in the immediate transmission of temperature, IDand installation status mark.Battery: A 3.0-3.6 Volt lithium battery powers the WOW wireless temperature sensor. Thebattery will last for more than 10 years in the idle state (as shipped from the manufacturer). TheWOW will transmit data for as long as 7 years at a rate of once each minute once started. TheWOW is completely covered with a water resistant rubber coating to protect the electronics fromthe environment and condensation. The user cannot replace the battery. The WOW may beplaced in a quiescent state (battery life greater than 10 years) by holding the installation switchclosed for more than 12 seconds.THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES, OPERATION ISSUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAYNOT CAUSE HARMFUL INTERFERENCE AND (2) THIS DEVICE MUST ACCEPTANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAYCAUSE UNDESERED OPERATIONFCC ID: M5ZWOWMADE IN USA
Wireless Temperature Sensor Data FormatThe Point Six, Inc. 418 MHz wireless temperature transmitters require a compatible receiverwith the ability to receive, error check and provide RS232 and RS422/485 interface. Thisdocument describes the data format provided by the HA8-wow 418 MHz. Receiver.The transmit packet from a receiver is approximately 15 milliseconds in duration and consists of13 bytes of data:1-byte ID/Mode field8-byte serial number2-byte temperature data2-byte CRC-16 error checkThe HA8-wow receiver processes this packet. The receiver performs a CRC-16 error check onthe packet. If the data is not accurate it is discarded. When a packet is received that is error freeit is converted to a 29-character packet and transmitted out the serial port at 19,200 Baud. Thedata is transmitted serially in ASCII Hex format and terminated with a CR character. This formatrequires two bytes for each byte of data; 14 data bytes x 2=28 plus the CR is 29 charactersThe resulting binary data format of the packet is:1-byte ID field this field will contain a byte whose LSBit indicates the service state of thetransmitter, 0=normal, 1=service mode.8-byte serial# this field contains the serial number of the 1-Wire sensor.2-byte temperature this field contains the temperature data stored MSB first in two'scompliment 16-bit form of 1/16 deg. C units.2-byte CRC-16 this is the originally received data packet CRC as described above.1-byte checksum the checksum is a mod 256 sum of all the ASCII character values in theresponse but does not include the CR
Example:D4287F44040000005A01602ED477<CR>This field is the mode indicator, the LS-bit which indicates the servicestate of the transmitter, 0=normal, 1=service mode.D4287F44040000005A01602ED477<CR>This field is the unique serial number of the 1-Wire temperaturesensor.D4287F44040000005A01602ED477<CR>This is the temperature data field; two's compliment 16-bit data storedMSB first in 1/16 deg. C units. The value shown is +22 Deg. C.D4287F44040000005A01602ED477<CR>This field is the CRC-16 error check as was originally received andchecked. This CRC is over the first 11 bytes of the packet starting withthe mode flags and ending with inclusion of the temperature data.D4287F44040000005A01602ED477<CR>This field is the mod 256 sum of all the ASCII character values in theresponse but does not include the <CR>.D4287F44040000005A01602ED477<CR>This is the CR terminator, 0Dhex.
FCC Radio Frequency Interference StatementWireless Temperature Sensor FCC ID: M5ZWOWNOTE: This equipment has been tested and found to comply with the limits for aClass B digital device, pursuant to Part 15, Subpart B, of the FCC Rules. Thisequipment generates, uses, and can radiate radio frequency energy. If not installedand used in accordance with the instructions, it may cause interference to radiocommunications.The limits are designed to provide reasonable protection against such interference in aresidential situation. However, there is no guarantee that interference will not occur ina particular installation. If this equipment does cause interference to radio or televisionreception, which can be determined by turning the equipment off and on, the user isencouraged to try and correct the interference by one or more of the followingmeasures:! Reorient or relocate the receiving antenna of the affected radio or television! Increase the separation between the equipment and the affected receiver.! Connect the equipment and the affected receiver to power outlets on separatecircuits.! Consult the dealer or an experienced radio/TV technician for help.MODIFICATIONSChanges or modifications not expressly approved by Point Six Inc. could void theuser's authority to operate the equipment.
