           To assure optimal radio performance and to ensure that exposure to RF energy is within
           the guidelines in the above standards, observe the following operating procedures:
           • Do not operate a transceiver when someone is within the distance noted below of the
             antenna (unity gain).
             – 45 cm (approximately 12 in) for the XDL Micro radio @ 2 W
              – 15 cm (approximately 6 in) for the XDL Micro radio @ 1 W
           • Do not operate the transceiver unless all RF connectors are secure and any open
             connectors are properly terminated.
           • Avoid contact with the antenna while operating the transceiver.
           • Do not operate the transceiver with a damaged antenna. If a damaged antenna comes
             in contact with the skin, a minor burn may result.
           • Do not operate the equipment near electrical blasting caps or in an explosive
             atmosphere.
           CAUTION – Changes or modifications not expressly approved by the FCC could void the user’s
           authority to operate the equipment.

           WARNING – The XDL Micro is classified as an intentional radiator of type radio transceiver.
           Conducted and radiated emissions of the standard XDL Micro do not exceed the
           requirements of FCC part 90 and ETS 300-113-2. OEM is responsible for full compliance of
           final product.




    General cautions
           CAUTION – You must handle the XDL Micro with care during installation. Remove the
           transceiver from its protective bag only in an ESD safe area.

           CAUTION – Incorrect impedance matching of the antenna, connectors, or cable degrades the
           performance of the transceiver.

           CAUTION – Internal circuitry protects the inputs and outputs against damage caused by
           high static voltages or electric fields. However, normal precautions are necessary to avoid
           application of any voltage higher than the maximum-rated voltages.

           CAUTION – Radiated and conducted signals to and from the transceiver may cause problems
           due to interference. Correct attention to frequency planning may reduce interference from
           radiated or conducted frequencies that fall within the pass-bands of the filters at the IF
           frequencies.

           CAUTION – To avoid interference between the signals, Pacific Crest recommends you do not
           bundle the antenna interface cable with other signal cables internal to your product.

Introduction
            This manual describes how to integrate the XDL Micro UHF transceiver (model numbers
            XDLM-0, XDLM-1 and XDLM-2) into your product. Pacific Crest recommends that you
            also read the XDLCONF User’s Guide for general information about configuring XDL
            Micro modems, and for detailed programming information.
            The XDL Micro is a general-purpose transceiver. It is compatible with the Pacific Crest
            ADL, PDL and RFM product families of radio modems. It is also compatbile with radios
            configured to use the SATEL®, South, Stonex Type 1, and Trimble TRIMTALK™ and
            TRIMMARK™ protocols. The XDL Micro transceiver is designed specifically for integration
            into new or existing products. Its small size, light weight, and power efficient operation
            provide superior performance in embedded systems.



    Legal restrictions
            The XDL Micro transceiver may be programmed to transmit only in accordance with a
            license issued by the radio authority of the country of operation. In the United States, this
            authority is the Federal Communications Commission (FCC). It is a violation of FCC rules
            if the XDL Micro operates on unlicensed frequencies or channel bandwidths. The XDL
            Micro uses extended frequencies and may contain functions that are not operational in
            the United States and its territories. Users should check with the radio authority of the
            country of operation for any restrictions that might apply.

    Transmit and receive pins
         The XDL Micro module uses pin 3 to receive data from an external device, such as
         a computer, GPS receiver, or weather sensor, and uses pin 14 to transmit data to the
         external device.
         The external device transmits data to the XDL Micro transceiver on pin 3, so according to
         the DTE naming convention, pin 3 is called the Tx Data pin. The external device receives
         data from pin 14 on the XDL Micro transceiver, so this is called the Rx Data pin.




    Antenna port
         A coaxial antenna port is provided to connect the antenna system to the transceiver. The
         antenna connector is a 50-Ohm MMCX type. Appendix B: Cables and Connectors, page
         17 provides part numbers and manufacturer information for compatible interface and
         RF connectors. Pacific Crest also provides custom manufactured cables designed to your
         specific needs. For specific cabling requirements, please contact us for a quotation.

         CAUTION – Do not transmit without first connecting an antenna as it may damage the
         transceiver.


    Compatibility
         The transceiver is compatible with most modes of operation supported by the XDL,
         ADL and PDL product families of radio modems. For an overview of the protocols and
         modes that the transceiver supports, see Protocols and Operation Modes, page 10. The
         compatibility also extends to the XDLCONF configuration software and the XDL Test
         application that are supplied as part of the XDL Micro Developer’s Kit (P/N 70888-88).

Protocols and Operation Modes
     You can completely configure the transceiver using the XDLCONF software. Configuration
     parameters define the DTE interface and the over-the-air protocol. Depending on your
     application, you may need to change the factory default settings.
     The following table shows the factory default settings of the transceiver.

Electrical Considerations

 Power supply
           The transceiver has a power supply connection on pins 18, 23, 24, 25, 26, 27, and 28 of the
           interface connector. If there is a potential for a ground path current loop due to incorrect
           power application, Pacific Crest recommends that you insert a fusible link in the signal
           ground to protect the transceiver.
           The XDL Micro transceiver is designed to operate with an unregulated DC voltage level at
           3.6 ±0.4 V. The power supply must be capable of sourcing 2 A.



 Data interface
           The transceiver has one serial port. It is a data port that has a simple 3-wire CMOS
           electrical interface with signals for transmitting data to, and receiving data from, the
           transceiver, and for providing a reference ground for the Tx (pin 3) and Rx (pin 14) signals.

           Note– Pacific Crest defines Tx and Rx as a DTE port. That is, an external device transmits
           data to the radio modem’s Tx pin (pin 3) and receives data from the radio modem’s Rx pin
           (pin 14).



 CMOS input/output protection circuitry
           The Tx signal terminates into a CMOS input port on the transceiver and should be driven
           externally or pulled to ground through a 10 kΩ resistor. The absolute maximum voltage
           applied to the Tx signal is -0.3 v to 3.3 V.
           The Rx signal is CMOS outputs. Note that loading the RX signal increases the power
           consumption of the transceiver and these should be limited to no more than 2.5 mA in
           order to maintain performance across the temperature range.

           CAUTION – Internal circuitry protects the inputs and outputs against damage caused by
           high static voltages or electric fields. However, normal precautions are necessary to avoid
           application of any voltage higher than the maximum-rated voltages.




 NC pins
           Pins 2, 4, 6, 8, 10, 12, 13, and 15 through 17 must be left with no connection.




11                                                                            XDL Micro Intergrator’s Guide


 Power down pin
         Pin 29 is the active low pin used to turn off power to the XDL Micro transceiver. The VIH
         (Voltage Input High) minimum is 1.2 V and VIL (Voltage Input Low) maximum is 0.3 V. It
         has a 10 K pull-up resistor to VCC. You can leave it unconnected (NC) if you do not want
         to turn off the XDL Micro transceiver.

     Error codes
         The transceiver performs a variety of start-up and run-time tests to ensure optimal
         operation. Tests include environmental as well as electrical measurements designed to
         avoid damage to the unit while maintaining adequate operation.
         A 50 Ω impedance coaxial MMCX style RF connector is provided to attach to an external
         antenna system. The MMCX connector offers a positive friction locking mechanism that
         is very reliable. In some circumstances it may be required to provide a physical stop to
         prevent the MMCX plug from becoming disconnected due to extreme shock or vibration.
         The transceiver requires an antenna and feed cable system that is impedance-matched
         to 50 Ω. Pacific Crest recommends that you use a high-quality RG-178 or equivalent
         coaxial cable for internal wiring of the RF signal from the MMCX connector to the panel
         connector. Pacific Crest also recommends you select an antenna that has a low VSWR
         (Voltage Standing Wave Ratio) (less than 1.5:1) and which is tuned for operation in the
         band of the XDL Micro transceiver.

         CAUTION – Incorrect impedance matching of the antenna, connectors, or cable degrades the
         performance of the transceiver.


     Shielding considerations
         The transceiver is designed to operate in proximity to noise-generating circuitry.
         However, certain radiated or conducted frequencies may degrade the performance of
         the transceiver or make it inoperable. When possible, provide well-grounded shielding
         between the transceiver and radiating circuits, such as power supplies, voltage-controlled
         oscillators, and crystal oscillators.




12                                                                       XDL Micro Intergrator’s Guide


     Frequency planning
         The transceiver contains a very sensitive, dual-conversion, super-heterodyne receiver.

         CAUTION – Radiated and conducted signals to and from the transceiver may cause problems
         due to interference. Correct attention to frequency planning may reduce interference from
         radiated or conducted frequencies that fall within the pass-bands of the filters at the IF
         frequencies.

         Pacific Crest recommends you first analyse the product frequency plan (including
         harmonics) and then use a spectrum analyzer to determine the potential for interference
         within the pass-bands of the various front-end and band pass filters.
         The following table indicates the frequencies and pass-band filter characteristics that are
         areas of potential interference.

          Second IF                      0.450                          0.010




13                                                                        XDL Micro Intergrator’s Guide


Mechanical Considerations

 EMI interferers
         The transceiver is easily mounted in new and existing products. The transceiver is
         specifically designed for operation in harsh environments. For best performance, mount
         the radio away from potential EMI radiators and route RF signals apart from digital
         signals.

         CAUTION – To avoid interference between the signals, Pacific Crest recommends you do not
         bundle the antenna interface cable with other signal cables internal to your product.




 Shock and vibration
         Sensitive receivers, such as that in the XDL Micro transceiver, are susceptible to
         interference due to mechanical shock and vibration. To reduce the potential for
         electromechanical interference, you must use a robust mounting scheme when you
         integrate the transceiver into other systems. You may need to use a thin damping pad
         between the mounting surface and the transceiver. Pacific Crest recommends that the
         damping pads you use are made of PORON® or a similar material.



 Thermal transfer
         The transceiver requires additional thermal heat dissipation in order to supply maximum
         output power at elevated ambient temperatures and high-duty cycles. The transceiver has
         a thermal sensor and a firmware controlled limit switch. To prevent permanent damage
         to the transmitter, the XDL Micro module shuts down when its internal temperature
         reaches 85 °C (185 °F). The integrated heat sink is adequate for most bench top testing,
         but when the transceiver is integrated into other systems you must consider additional
         thermal heat sinking. The transceiver produces approximately 6 Watts of heat at full RF
         power out.
         For mounting diagrams and specification, see Appendix A: Mounting Guide, page 15.



 Materials
         The transceiver is housed in a metal shield that is a conductor and is electrically
         connected to the ground and signal ground pins.
