Plastic Panel MountMetal Panel Mount4 x 5 x 5"ExplosionProofDESCRIPTIONFinally a truly universal Wirelesssystem that complies to any country'sR.F. requirement! OTEK's newMBTR can be ordered with anypower, band, and operation as permit-ted by the country that is in use. Thismeans that your product does not needto be changed at all! The sameP.C.B. and I/O are used for all bandsand due to FCC rules OTEK mustprogram the MBTR for the specificpermissible bands, output power, andoperational mode (see License).The T & R: The MBTR is availableas transmitter only (T), as receiveronly (R), as a repeater (RPR) or as atransceiver (TR). As a "T" the unitaccepts up to 4 different inputs fromdry contacts or push buttons (keyfob)or 3V logic and transmits the "ON" or"OFF" state of the inputs individuallycoded. As an "R" the unit decodes thespecific input data and turns "ON" or"OFF" its Open Collector Transistor(O.C.T.), its 3V TTL logic, or its relay(depending on the output type youselect).The "RPR": The repeater almostdoubles the range per unit. The "RPR"can also be used as "T" overriding itsreceiving function so any "RPR" canbe used as an Alarm/Data originatorand the other "RPR"s as relays of theID and data to the master receiver.The "TR": As a transceiver (TR) theMBTR is available in 2 versions.Sanitary to520-748-7900FAX: 520-790-2808E-MAIL:sales@otekcorp.comhttp://www.otekcorp.com SINCE 19744016 E.

Gas, Detectors, Tally Polling,Battery Operationinstructions and benefit from propriatory de-sign and lower cost, but you'll have to getyour own FCC license.B. With UART I/O, in this configuration theMBTR does all the work for you, all youneed to do is interface it to your UART andfollow OTEK's list of commands. FCClicense is propriatory to OTEK and OTEKtransfers it to you at no cost upon receipt ofyour PO, payment and affidavit of use. Thiswill save you thousands of dollars and monthsof bureaucratic red tape. The UART canbe disabled to use as Virtual WireTM.LICENSE:OTEK only licenses the FCC approvedbands and output power per Part 15.247(902-928MHz, soon for 2.4GHz) or Part15.231 (315 and 433MHz periodic opera-tion). Any other non-FCC approved band orpower ordered must be accompanied by anofficer's signed affidavit that the unit's willnot be used within FCC regulated areas andthat the user is responsible for obtaining thelicense from the country/countries to be ex-ported to.No Affidavit-No Order Entry.How it works:The MBTR series uses internally controlledfrequency hopping technique and program-mable output power P.A. as well as errorchecking to insure reliable communicationover the specified range. For extendedranges it is permissible to increase the gainA. With SPI (4 wire) I/O and Nomicrocontroller. This means that you writeyour own program with OTEK'sPRELIMINARYNEW
of the unit by using a higher gain antenna than the unitygain supplied (contact OTEK for more information).Since the MBTR has "room to spare" on the "TX" modewhen in the 902-928 FH band (100mW at present), onecould use an antenna with up to 20dBM for the "TX" or"RX" without infringing the law. No restrictions apply tothe receiver's gain except for noise amplifications. Con-sult FCC at www.fcc.gov for further details.The Packages:A. "T": The transmitter is available in these packagesand with these input configurations:A.1.“Naked” P.C.B. with 14 position header tosolder or plug in your P.C.B. measuring 1"x1"x0.3"(25x25x8mm) with eitherA.1.1 Soldered helical antenna (unity gain) orA.1.2 With RPSMA connector to screw thesupplied WHIP antenna (unity gain standard).The helical antenna increases the length to1.7” (43mm) for 868 and 915MHz bandsand 2”(50mm) for 315 and 433MHz bands.The WHIP antenna increases the length by 4”(100mm) for 868 and 915MHz and by 6”(150mm) for 315 and 433MHz. The antennaconnector (RPSMA) allows you to install theantenna remotely from the MBTR but you’llloose about one (1) dBm per every 3ft (1M)of coax cable. In the Naked configuration theMBTR-“T” only accepts either dry contactor 3V compatible logic.Power input is limitedto either 3V (2.75-3.3V) or 4 to 12VDC.A.2.KeyFob: In this package the MBTR-”T”contains its own 3V lithium battery in a key chainmodule only 1.25x2.25x.4” (32x57x10mm) withfour (4) buttons. Battery life expectancy dependson the usage (frequency of use and output power)but normally is good for about 1000 operations atintervals of 15 minutes for a duration of 5 secondsor less.Only "M" & "L" modes are available. SeeNote 2.4A.3.Miniature Case: (Plastic or Metal):Antenna: WHIP only screwed into the built-inRPSMA connectorPower: 3, 4-48VDC and 90-265VACInputs: Dry contact or 3V logic (others on request)Mounting: Panel or chassis mount only1x1.5x2.75” (25x38x69mm).A.4.Nema 4X: Only 2x2.5x4” (50x63x100mm) and itis wall, pipe, or panel mount. The 868 or 915MHz antenna extends the 4” length to 8” (200mm)and 315 or 433Mhz by 6” to 10” (250mm).Power and inputs are the same as for theminiature case (others on request).NMH: (3A/Hr.) Battery Pack is optional.Duration depends on the power and fre-quency of transmittion (typical 3+ years).A.5.Sanitary: This case complies to SteamWash Down requirements and withstands upto 250ºF (120ºC) steam or hose down. Theantennas extend the height by 4 or 6” (100 or150mm). The all aluminum, water tight 3x6x6(75x150x150mm) case can be wall, pipe, orpanel mount and has space for up to 3 units.A.6.Explosion Proof: This 5” (125mm) diametercase only 4” (100mm) deep can be pipe orwall mount. The MBTR is inside andcoupled to the antenna on the tempered glasswith OTEK’s exclusive high throughputtechnique retaining the agency’s classificationfor Class I, Div 1&2 Hazardous Environ-ments. The antenna swivels 360º for properorientation and the 1/2 NPT ports (2) can beused to mount it or use the ears. There isspace inside the E.P. for OTEK’s NMHbattery pack (4.8V @ 3AHR) for manyhours of operation since the MBTR-“T”only consumes 1µA during stand by, 8mAduring awake and 70mA worst case atmaximum output power (25mA Nominally.A.7. Batteries: How long do they last? Howoften will the MBTR-T transmit? How big isthe battery? OTEK’s BP-48-4 is a 4 batterypack with NMH batteries of 3A/hr rating,enough for a minimum of 42 hours of continu-ous (?) operation (3000/70 mA) at maximumpower or more realistic over 365 days at 50/day for 5 seconds at medium power. Thebattery charger (p/n BC-48-4) is availableand don’t forget extra batteries p/n NMH1.2-3 (requires 4 each). The battery pack can beincluded in NEMA 4X, Sanitary and explo-sion Proof (See Ordering Information.B. “R”: The receivers use the same board as the“T” with the same pinout except the inputsbecome outputs. The "R" has 4 miniature LEDson the back that are lit when the transistor outputsare low.B.1.Naked: Same options and restrictions as the“T” (see A.1.).MBTR Page 22
B.2.Miniature Case: You have the option of eitherO.C.T. or relays. On the relays you have theoption of either normally closed (N.C.) or nor-mally open (N.O.) contacts due to pinout count.Power: 3V only for O.C.T., Isolated 4-48VDCand 90-265VAC for either relays or O.C.T.B.3.NEMA 4X Case: Since all we do is install theminiature case inside the NEMA 4X case, thesame options and restrictions of the miniaturecase (see B.2) apply (also see A.4).Note: On special request the NEMA 4X can befitted with 4 each SPDT 10 amp relays, contactOTEK.B.5.Sanitary Case: Again we install the miniaturecase (up to 3 ea.) inside the sanitary case, conse-quently all the options and restrictions of theminiature case (see A.3 and B.2) apply.B.6.Explosion Proof: (see A.6): The same featuresof the E. P. for the “T” apply here except wedon’t recommend the battery pack with the relayoption since each relay consumes about 50mA @5VDC. The “R” should always be “ON” (about7mA) unless you control it for “stand-by” and“wake-up”.B.7.Batteries: Not recommended for “R” (see A.6)but if you must, specify at time of ordering (seeA.7).Warning: You CANNOT change frequency bandand output power. It is done at the factory due toFCC and antenna matching.C. Repeater (RPR)Repeater: In this mode, the MBTR receives data onone frequency channel and transmits it in another inalmost Real Time except for the latency and limited bythe Data Rate (see specs.). This configuration is usefulfor doubling the range and/or "Mesh" communicationtechniques thanks to the frequency hopping of theMBTR. The "RPR" can be automatically switchedfrom "RPR" to "T" when any one of its 4 inputs isdriven "Low" forcing the unit to transmit its ID (Loca-tion) and alarm input type (If only I.N.S. would listen,we could detect illegal border crossers "Pronto") toother RPR to computer or satellites.D. “TR”: The “TR” (Transceiver) uses the same PCB asthe “T” or “R” except we populate it differently. If it isordered for SPI I/O (Option S) we don’t install themicro, if ordered with UART (Option M) and/orother options such as A/D, we install themicrocontroller and program it as required.Pinout: We use the same pinout as the “T” and “R”as much as possible so you don’t have to change yourPCB except for some possible jumpers if you use all4 versions on your same product.D.1.SPI: (Option "S") In addition to the 4 SPI I/Othe “TR” gives you access to other control pinsof the internal microcontroller in the R.F. chip,such as valid data or interrupt input, clock out(to synchronize your uC), FIFO interrupt or datafilter input or received data clock out, FIFOselect input or received data output or FSK datainput. With the SPI you can control, amongother things, the “low bat” detection threshold,sleep, stand-by, and wake-up, status register,P.O.R., 2 each 8 bit register for TX and 16 bitfor RX. Sorry, you cannot change the band,center frequency, bandwidth or higher outputpower but you can change down power (TX)and the sensitivity of the LNA (as RX). Refer touser’s manual for more information or get the uCversion, it’s all done for you or OTEK cancustomize it to your needs. Don’t forget, all I/Oare 3V logic!D.2. µµµµµC (Option C): Here we do it all for you! Allyou need is a 3V logic compatible I/O. Thisversion has many forms of operation all viasimple configuration commands and if you don’thave a UART compatible I/O you can disable itand use the pins as data input and output. Somefunctions are:D.2.1.Virtual WireTM: Whatever you put at theinput, you’ll get at the output (3V logic).D.2.2.*Latched: A “logic 0” or dry contactclose at the inputs (4) will latch thereceiver’s output until a general Resetcommand is sent or the “RX “ manuallyreset, but you must configure the units foreither TX or RX.D.2.3.Start-Stop: The first “logic 0” pulse at theTX will send an “ON” command to the RXfor that specific channel (1 of 4), the secondpulse will send a reset command to the RXfor that channel.D.2.4.*Momentary: On falling edge (or contactclosure) at the input, the "TX" will transmitthe “ON” signal to the "RX" for it to turn itscorresponding output “ON” (1 of 4). Onthe rising edge (or contact opening) the"TX" will transmit the “OFF” command forthe “RX” to reset its output(s). That is whywe call it Virtual WireTM!* = Only Available modes in "Key-Fob" case.D.2.5. 10 Bit A/D: The "MBTR" has a 4channel 10 bit A/D that can be enabled tomeasure (as a "TX") and transmit thewireless data to the "RX" for it to output itin digital format through its UART port.A simple command enables/disables theA/D or converts it to digital I/Os.MBTR Page 33
MBTR Page 4D.2.6 Counter: A 16 Bit UP/Down Counter/Timer is available so you can use it asrequired or as a PWM with externalcircuitry. Again, one MBTR should beconfigured as "TX" and another as "RX".D.2.7 FIFO: Almost like our Virtual WireTM butyou can transmit and receive in "Bursts" up to8 bit wide and yu can do it in a two waymode by switching the MBTR from TX toRX upon completion of data sent. Rememberthat the MBTR has 2 each, 8 bit storageregisters. The first to store incoming data andthe second to store outgoing data (FIFO).This can also be used to store "Preamble" andID data.D.2.8 Custom Configurations: OTEK will behappy to customize your confidentialpropriatory firmware requirements as well ashardware, whether it is one piece or millions.All of our customers are important (we do notcheck your size). D.2.9 Package: As of this writing, the "TR"version of the MBTR is only available in"Naked" configuration for OEMs witheither helical or whip antenna and 3V or 4- 12VDC power.
