Connector Operation44-34.1.2 Configure Your Connector/TransmitterNow that you have connected your USB cable to your PC and connectortransmitter you will complete the following steps to configure yourconnector/transmitter before placing the unit into operation. You will be usingthe configuration software utility that you installed onto your PC in Section 3.2.If you have not installed the configuration software utility you should do sonow.During this procedure you will be setting the following parameters in yourconnector transmitter.Channel NumberThis sets a unique address number into your connector/transmitter. Later, whenyou set up your measurement software you will again set channel numbers toreceive readings from the corresponding unit(s). Each connector must be set for adifferent channel number for your system to operate correctly.If you will be using more than one receiver unit in your area it is important toset the connector/transmitter address numbers to be a corresponding numberin your TC-Central software. See Examples below.For the first receiver: Set the channels on your connector/transmitters to 101, 102, 103, 104, etc.Then set the channels in your TC-Central user software to match.For the second receiver: Set the channels on your connector/transmitters to 201, 202, 203, 204, etc.Then set the channels in your TC-Central user software to match.This numbering scheme can be expanded to match the number of receivers youare using.Sample RateThis will program your device to transmit 1 data reading to your receiver at aspecified time interval. Available settings are 2, 3, 5, 15, 30, 45, 60, 75 or 90secondsThe sample rate you set will have the most direct effect on the life of the battery inyour connector/transmitter. It is recommended that you set the longest sample timethat your application can live with to extend time between battery replacement.See Section 6 for more information on battery life.STEP 1.

If nearby metal gets too close to yourconnector/transmitter, it has the potential to interfere with the way the unitradiates and may cause signal lose or possibly even the inability to communicateat all with your receiver. 4.2.3 InstallationWhen installing your connector/transmitter it is important to position yourdevice in such a way as to optimize the antenna location within what’s known asthe “Fresnel Zone”.The Fresnel Zone can be thought of as a football-shaped invisible tunnel betweentwo locations that provides a path for RF signals between yourconnector/transmitter and your receiver.Figure 4-12 Fresnel ZoneSPACERSMWTC TRANSMITTERMOUNTING SCREWSMOUNTING PLATENOTE:FRESNEL ZONE®TXWIRELESS THERMOCOUPLE CONNECTORTC–+MWTCLOWBATTPRESSSETUPPRESSI / OTYPERECEIVERANTENNA
Connector Operation44-9In order to achieve maximum range, the football-shaped path in which radiowaves travel must be free of all obstructions. Obstacles in the path (especiallymetal) will decrease the communication range between yourconnector/transmitter and receiver. Also, If the antennas are mounted just barelyoff the ground, over half of the Fresnel zone ends up being obstructed by theearth resulting in significant reduction in range. To avoid this problem, theantennas should be mounted high enough off of the ground so that the earthdoes not interfere with the central diameter of the Fresnel zone. It is important to understand that the environment may change over time due tonew equipment or machinery being installed, building construction, etc. If newobstacles exist between your connector/transmitter and receiver, the devices canbe raised on one end or on both ends to hopefully clear the Fresnel Zone ofobstructions.No co-location with other radio transmitters is allowed. By definition, co-location is when another radio device or it’s antenna is located within 20 cm ofyour connector/transmitter and can transmit simultaneously with your MWTCunit. Never install MWTC connector/transmitters within 20 cm or less from eachother.Never use your MWTC connector/transmitter as a portable device. Your unithas been designed to be operated in a permanent installation only. 4.2.4 AntennaUse of any other antenna then what’s supplied with your device will void allFCC and CE regulatory compliance.Additional Information on installation and system operation can be found inSection 6.NOTE:NOTE:NOTE:NOTE:NOTE:

Section 6 - System Operation6.1 IntroductionCompared to wired thermocouple systems, wireless thermocouple systemsprovide much simpler installation. Based on the physical principle of thepropagation of radio waves, certain basic conditions should be observed. Thefollowing simple recommendations are provided to insure proper installationand correct operation of your MWTC Series system.6.2 RF Communication BasicsThe Model MWTC wireless Thermocouple Connector/Transmitter sendswireless transmissions to the MWTC-REC1 receiver. The receiver checks theincoming data for accuracy and processes this data for use by the measurementsoftware on your PC. Radio signals are electromagnetic waves, hence the signalbecomes weaker the further it travels. While radio waves can penetrate somesolid materials like a wall, they are dampened more than when a direct line-of-sight between the transmitting and receiving antenna exist.6.3 Basic System OverviewThe MWTC wireless thermocouple system is comprised of only two maincomponents; a Thermocouple Connector with a built-in battery powered radiotransmitter, and a USB powered radio receiver. Figure 6-1 Basic System OverviewUp to 48 connector/transmitters can be used with one Model MWTC-REC1receiver.®TXPWRMWTC SERIESWIRELESS RECEIVER®TXWIRELESS THERMOCOUPLE CONNECTORTC–+MWTCLOWBATTPRESSSETUPPRESSI / OTYPE®TXWIRELESS THERMOCOUPLE CONNECTORTC–+MWTCLOWBATTPRESSSETUPPRESSI / OTYPE®TXWIRELESS THERMOCOUPLE CONNECTORTC–+MWTCLOWBATTPRESSSETUPPRESSI / OTYPE®TXWIRELESS THERMOCOUPLE CONNECTORTC–+MWTCLOWBATTPRESSSETUPPRESSI / OTYPE®TXWIRELESS THERMOCOUPLE CONNECTORTC–+MWTCLOWBATTPRESSSETUPPRESSI / OTYPE®TXWIRELESS THERMOCOUPLE CONNECTORTC–+MWTCLOWBATTPRESSSETUPPRESSI / OTYPE®TXWIRELESS THERMOCOUPLE CONNECTORTC–+MWTCLOWBATTPRESSSETUPPRESSI / OTYPE®TXWIRELESS THERMOCOUPLE CONNECTORTC–+MWTCLOWBATTPRESSSETUPPRESSI / OTYPE®TXWIRELESS THERMOCOUPLE CONNECTORTC–+MWTCLOWBATTPRESSSETUPPRESSI / OTYPE6-1System Operation 6

6-4System Operation6.6 Environment/Operating Conditions6.6.1 EnvironmentOmega’s MWTC series connector/transmitter and receiver unit has beendesigned to be fixed mounted and operated in a clean and dry indoorenvironment. Care should be taken to prevent the components of your wirelesssystem from being exposed to moisture, toxic chemicals and extreme cold or hottemperature that are outside the specifications listed in this manual.6.6.2 Operating ConditionsThe following is a list of basic good practice you should apply when operatingyour wireless system.• Never operate your wireless device outside the recommendedenvironmental limits specified in this manual.• Never operate your wireless device in flammable or explosiveenvironments.• Never use your wireless device in medical, nuclear or other dangerousapplications were failure can cause damage or harm.• Never operate your transmitter/connector with any other battery or powersource than what’s specified in this manual or on the battery compartmentlabel.• No co-location with other radio transmitters is allowed. By definition, co-location is when another radio device or it’s antenna is located within 20 cmof your connector/transmitter and can transmit simultaneously with yourMWTC unit.• Never install a connector/transmitters within 20 cm or less from each other.• Never use your connector/transmitter as a portable device. Your unit hasbeen designed to be operated in a permanent installation. • Never install and/or operate your connector transmitter closer than 20 cmto nearby persons.• Never operate your connector transmitter with any other antenna than whatis supplied or listed here in this manual for approved use.6
NOTE:6-5System Operation6.7 Determining and Maximizing RangeThe available maximum range specified for the wireless Series system in thismanual is only achievable under optimum installation conditions. Mountingheight, obstructions in your “Fresnel Zone” and ambient conditions can cause adecrease in signal strength resulting in a shorter range between yourtransmitter/connector and receiver unit.The following recommendations will help to improve the range of your wirelesssystem.Position your receiver in a central locationWhen multiple connector/transmitters are in operation, position your receiverunit in a central space if possible in equal distance to each connector transmitter.Figure 6-5 Determining Maximum RangeTest your system before permanent mountingBefore permanently mounting your connector/transmitters in your applicationtry moving the devices to different locations and mounting angles to determinewhat installation achieves the best signal strength.Move your system components higher off the floor and away from exterior wallsAvoid installing your system components to close to the floor or near yourbuildings exterior walls. The closer your connector/transmitter and receiver unitare the greater the interference and lose of signal strength will be.Maintain a line of sight (LOS) between antennasMaintaining a line of sight between your connector/transmitter and receiverunit will produce greatly improved signal strength over a system were theantenna’s in your system have obstacles blocking them. Maintain a constant ambient temperature environmentMaintaining a constant ambient temperature environment is important toachieving maximum signal strength. Exposing your system components toextreme hold or cold temperatures, or sudden changes in ambient conditionswill have an effect on the performance of your system. 6STORAGE ROOMCONTROL ROOMOFFICE OFFICEPCMANUFACTURINGAREAMANUFACTURINGAREARECEIVERTRANSMITTERCHAN 3CHAN 6CHAN 5CHAN 4CHAN 2CHAN 1TRANSMITTERTRANSMITTERTRANSMITTERTRANSMITTERTRANSMITTER
6-6System Operation6.7.1 Operation in BuildingsYour Connector/Transmitter sends wireless data transmissions to a receiverconnected to your PC. Radio signals are electromagnetic waves. A radio signalbecomes weaker the further it travels. Range is decreased by different types ofmaterials found in the direction of the signals propagation. Radio waves canpenetrate most types of wall materials, but they are dampened more than theywould be by a direct line-of-sight installation. 6.7.3 Building MaterialsExamples of how different types of wall material may reduce your signal:Material Type Possible Signal ReductionWood, Plaster, Sheetrock, Uncoated 0 to 10%Glass w/o Metal, FiberglassBrick, Pressboard 5 to 35%Reinforced Concrete 10 to 90%Metal Walls, Metal Doors, Elevators,Metal Stair Cases, Metal Piping, 90 to 100%Metal Mesh, Metal ScreeningFigure 6-6 Operation In BuildingsAvoid dampening materials by repositions the connector/transmitting and/orreceiver.6.7.2. Penetration Angle of Radio Waves Through WallsThe angle at which the transmitted radio signal hits a wall is very important andalso has a big effect on maximizing range. Signals between yourconnector/transmitter should be transmitted as directly as possible.6
NOTE:6-76.8 Antenna Basics 6.8.1 Antenna BasicsBy definition, an antenna is a device used to transform an RI signal, traveling ona conductor, into an electromagnetic wave in free space. Antennas demonstrate aproperty known as reciprocity, this means that an antenna will always maintainthe same characteristics regardless if it is used to transmit or receive. Mostantennas are resonant devices, which means they operate efficiently over arelatively very narrow frequency band. An antenna must be tuned to the samefrequency band of the radio system to which it is connected, otherwise thereception and the transmission will be impaired. The antennas in your wirelessthermocouple connector system have been tuned to operate in the 915 or 868band.6.9 Antenna PlacementProper antenna installation is important and will allow you to achieve maximumperformance and range between your connector/transmitter and receiver unit.Your connector/transmitter should not be installed on the same side of the wallas the receiver. If mounted close to each other on the same wall, the radiowaves are likely to be subject to interfering dispersions or reflections. The bestpositioning is to have the connector/transmitter installed on the opposite orconnecting wall to the receiver.6.9.1 Horizontal Antenna PlacementFigure 6-7 Horizontal Antenna PlacementIf your Connector/Transmitter is mounded in a horizontal position in yourapplication you should mount your receiving so that the same polarization isachieved with the receiving antenna.

Transmitting data placesa big demand of the battery in yourconnector/transmitter. The transmit rate is thesingle most contributing factor in the life of yourbattery. The slower the transmit rate you set, thelonger the battery in your device will last. Thetable below give some estimates on how long thebattery should last vs. the transmit rate youselected when you setup yourconnector/transmitters and under normaloperating conditions.Transmit Time Estimated Battery Life1 Sample/2 Seconds 60 days1 Sample/3 Seconds 84 days1 Sample/5 Seconds 128 days1 Sample/10 Seconds 215 days1 Sample/15 Seconds 278 days1 Sample/30 Seconds 393 days1 Sample/45 Seconds 455 days1 Sample/60 Seconds 500 days1 Sample/120 Seconds 570 days®TXWIRELESS THERMOCOUPLE CONNECTORTC–+MWTCLOWBATTPRESSSETUPPRESSI / OTYPE®TXPWRMWTC SERIESWIRELESS RECEIVERSystem Operation6Figure 6-8 Vertical Antenna Placement
