9XDL Micro Intergrator’s Guide Transmit and receive pinsThe 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 portA 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.CompatibilityThe 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).
10 XDL Micro Intergrator’s Guide Protocols and Operation ModesYou 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.Setting Default settingChannel 1Baud Rate 38400Parity NoneSoft Break Disable OffTX Power 0.5 WMode Transparent EOT TimeoutLink Rate 9600 bps GMSKEOT 50 msRepeater Delay 0CSMA On (CSMA is required to be on only in the U.S.A. You should turn off CSMA in the European Union.)FEC OnScrambling OnSensitivity HighLocal Address 0Destination address 255Up to 32 frequencies are stored in the configuration memory called the channel table. The selection of channels is subject to correct licensing of the corresponding frequencies by the appropriate governmental agency. For instructions in creating and uploading channel tables into the transceiver, refer to the XDLCONF User’s Guide.The transceiver supports multiple protocols and modes of operation including:• Transparent with EOT Timeout• Transparent with EOT Character• TRIMTALK II/IIe• TRIMTALK 450S• TRIMMARK 3• SATEL• South• Stonex Type 1• Transparent FST
11 XDL Micro Intergrator’s Guide Electrical ConsiderationsPower 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 pinsPins 2, 4, 6, 8, 10, 12, 13, and 15 through 17 must be left with no connection.
12 XDL Micro Intergrator’s Guide Power down pinPin 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 codesThe 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 considerationsThe 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.
13 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.Circuit Center frequency (MHz) Bandwidth (MHz)RF front-end 438 70First IF 54.45 0.015Second IF 0.450 0.010
14 XDL Micro Intergrator’s Guide Mechanical ConsiderationsEMI interferersThe 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 vibrationSensitive 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 transferThe 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. MaterialsThe transceiver is housed in a metal shield that is a conductor and is electrically connected to the ground and signal ground pins.
15 XDL Micro Intergrator’s Guide Appendix A: Mounting GuideStandard enclosureThe following figure shows mounting holes locations and overall dimensions for the transceiver. CAUTION – Screws used to mount the transceiver to a mounting plate must not penetrate the mounting surface of the transceiver by more than 0.20 inches.
