M5ZPRO1Wireless Temperature Probe

FCC ID: M5ZPRO1 Installation and Operation Instructions for the Wireless Temperature Probe, Model WOW-PRO. Point Six, Inc. Wireless Temperature Sensor Probe Model WOW-PRO1 Installation and Operation Instructions The WOW-PRO1 wireless temperature sensor transmits both a digital temperature and a unique serial number to a 418 MHz receiver. The WOW is enclosed in a 304 stainless steel tube enclosure for direct food penetration in the environment to be measured. WOW-PRO1 is battery operated. Application: Apply the sensor to the food object by penetrating the food to be monitored with the pointed end of the tube. Make sure that the penetration is at least 1 inch past the tapered point. Service Function: The wireless temperature sensor probe has an installation mode switch. A momentary magnetic reed switch will start the convert/transmit cycles. When new and until this is feature is activated the WOWPRO1 will not transmit. The WOWPRO1 will transmit a special installation status mark in the data packet immediately after the installation/start switch is activated. After the start further activations of the installation switch will result in the immediate transmission of temperature, ID and installation status mark. Battery: A 3.0-3.6 Volt lithium battery powers the WOWPRO1 wireless temperature sensor probe. The battery will last for more than 10 years in the idle state (as shipped from the manufacturer). The WOWPRO1 will transmit data for as long as 10 years at a rate of once each minute once started. The WOW is completely enclosed in 304 stainless steel tupe. The user cannot replace the battery. The WOWPRO1 may be placed in a quiescent state (battery life greater than 10 years and no transmissions) by holding a magnet at the base of the antenna between the 304 stainless steel tube and the SMA connector for more than 5 seconds. The Point Six, Inc. 418 MHz wireless temperature transmitters require a compatible receiver with the ability to receive, error check and provide RS232 and RS422/485 interface. This document describes the data format provided by the HA8-WOW, HA9- WO W or HA10-WO W 418 MHz. Receivers. The transmit packet from a receiver is approximately 15 milliseconds in duration and consists of 13 bytes of data: 1-byte ID/Mode field 8-byte serial number 2-byte temperature data 2-byte CRC-16 error check The WOW receivers process this packet. The receivers perform a CRC-16 error check on the packet. If the data is not accurate it is discarded. When a packet is received that is error free it is converted to a 29-character packet and transmitted out the serial port at 19,200 Baud. The data is transmitted serially in ASCII Hex format and terminated with a CR character. This format requires two bytes for each byte of data; 14 data bytes x 2=28 plus the CR is 29 characters The resulting binary data format of the packet is: 1-byte ID fieldthis field will contain a byte whose LSBit indicates the service state of the transmitter, 0=normal, 1=service mode. 8-byte serial#this field contains the serial number of the 1-Wire sensor. 2-byte temperaturethis field contains the temperature data stored MSB first in two's compliment 16-bit form of 1/16 deg. C units. 2-byte CRC-16this is the originally received data packet CRC as described above. 1-byte checksumthe checksum is a mod 256 sum of all the ASCII character values in the response but does not include the CR Example: D4287F44040000005A01602ED477<CR> This field is the mode indicator, the LS-bit which indicates the service state of the transmitter, 0=normal, 1=service mode. D4287F44040000005A01602ED477<CR> This field is the unique serial number of the 1-Wire temperature sensor. D4287F44040000005A01602ED477<CR> This is the temperature data field; two's compliment 16-bit data stored MSB 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 and checked. This CRC is over the first 11 bytes of the packet starting with the 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 the response but does not include the <CR>. D4287F44040000005A01602ED477<CR> This is the CR terminator, 0Dhex.

Dear Mr. Compton, Thank you for your business. This was a well organized and complete application. I have only one issue to confirm in order to grant this application. 1. The data table in the test report does not indicate a reading for the average value of the fundamental emission. A peak value is indicated at 88.28dbuV/m@3m. This value on its own fails the average limit. From your discussion of the devices duty cycle I believe the correction factor for the worst case duty cycle is 20log(16x50%/100mS) or more than 20dB. This averaging factor when applied to the peak measurement would result in an average data point which meets the FCC limit. Please confirm that you agree with and support my analysis. Mr.. Quinlan, Your analysis is correct, as it has been with the previous WOW products for which equipment authorization has been issued. These devices all operate in the same manner and you have an accurate understanding of averaging factor.

FCC ID: M5ZPRO1 Operational description of the Wireless Temperature Probe Transmitter, Model WOW-PRO Description of the circuit functions ground system and antenna of the Point Six, WOW-PRO1 Wireless temperature transmitter: The WOW-PRO1 wireless temperature sensor is a lithium battery operated microprocessor based 418 MHz. transmitters that transmit both digital temperature data and a unique 64-bit serial number. The microprocessor is brought up from a power down state every 4 seconds by a DS2417 time of day clock interrupt output. The temperature is measured with a DS18B20 digital temperature sensor, which has a unique 64-bit serial number that can be read by the microprocessor. The microprocessor counts the 4-second interrupt cycles from the DS2417 clock until the transmit period has expired. The microprocessor then reads the temperature from the previous temperature conversion, combines it with the serial number data and transmits the entire data packet serially with a Linx Technologies TXM-418- LC-R 418 MHz. Transmitter module. The microprocessor then starts another temperature conversion cycle and powers down into a quiescent state to wait for the next interrupt from the DS2417 clock. The PC board bottom layer is a ground plane and the antenna is a Linx Technologies model ANT-418-CW-RH. The entire electronics is sealed in 304 stainless steel tube.

This is well within the maximum bandwidth specified by 47CFR15.233(c). Signed:______________________________Date:_________ D. R. Bush, PE, NCE, President dBi Corporation FCC ID: M5ZPRO1 To Whom It May Concern: The Point Six, Inc. wireless temperature probe transmitter (model WOWPRO-1) transmits a 15-16 millisecond packet once each 600-10 seconds. This is identical to the data packet timing of a previously certified “M5ZWOW”. I will restate this timing below. The packet consists of transmitter-on/transmitter-off timing that represents the serial number and humidity/temperature data. The duty cycle is approximately 50%. The packet time can vary with serial number between 14-16 milliseconds. The packet data is controlled by a microprocessor whose timing is based on a ceramic resonator that is very stable. The packet below (figure #2) illustrates a typical data packet, the worst case, 16 milliseconds, cannot be shown because serial number would have to be forced to make this so. Figure #1 illustrates the overall timing; a packet is sent each 10 seconds in this worst case. The battery used during the tests was new and was a standard 3.6 Volt Lithium cell. The battery is a 3.6 Volt Lithium chemistry, which has a flat discharge curve from new to about 90% used. In this application the battery requires about 5 years to discharge to the point that it cannot be used. The battery was used for no other purpose and had operated in the test unit for only a short time when the test was performed.
