2 Federal Communications Commission This device complies with Title 47 CFR § Part 27 of the federal code. Specifically, 47CFR § 1.1310, Table 1, Limits for General Population/Uncontrolled Exposure. This device must be operated as supplied by XetaWave LLC. Any changes or modifications made to the device without the express written approval of XetaWave LLC may void the user’s authority to operate the device, pose violations and liabilities. Caution The model number Xeta7M-T has a maximum transmitted output power of 35 dBm when used in the 757-758MHz and 787-788MHz bands. The transmit antenna shall be kept at least 82 cm from physical space where humans may exist. Additional details may be found in the “RF Exposure Calculations” at the end of this section. These limits are designed to provide reasonable protection against harmful energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: 1) Reorient or relocate the devices and/or antennas. 2) Increase the separation between the equipment and the receiver. 3) Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. 4) Consult the dealer or an experienced RF/radio/Electronics professional for help. FCC Notifications
3 NOTE TO OEMS: For host manufacturer’s when using a certified module, the following must be adhered to: 1. If (1) the module’s FCC ID is not visible when installed in the host, or (2) if the host is marketed so that end users do not have straightforward commonly used methods for access to remove the module so that the FCC ID of the module is visible; then an additional permanent external label referring to the enclosed module: “Contains Transmitter Module FCC ID: PEJ-XKJS7” or “Contains FCC ID: PEJ-XKJS7” must be used. 2. The host OEM user manual must also contain clear instructions on how end users can find and/or access the module and the FCC ID. \ WARNING These radio systems shall be installed by a RF/radio professional familiar with the applicable rules. Installation of all antennas shall be performed in a manner that will provide at least the MPE Distance from the direction of maximum radiation, to any user or member of the public and consistent with the settings in the applicable antenna installation compliance section below.
4 FCC antenna compliance Since professional installation is required, standard RF connectors are used. Adapters or custom coaxial cables may be required to connect the radio output connector to the desired antenna. Any antenna from a reputable manufacturer with desired bandwidth, gain/pattern coverage, and have an input surge impedance of approximately 50 ohms can be used. Maximum antenna gain of 11dBi in both the 757-758MHz and the 787-788 MHz bands. Exposure Compliance FCC ID: PEJ-XKJS7 It is the responsibility of the licensee or user to guarantee compliance with the appropriate MPE regulations when operating this device in a way other than described herein. The installer of this equipment must ensure the antenna is located or oriented such that it does not emit an RF field in excess guidelines as posted in the 47 CFR Bulletin 65/47CFR § 1.1310 of the Federal Communications Commission, or the Council of European Union as appropriate. The XetaWave XETA7 uses a low power radio frequency transmitter. The concentrated energy from an antenna may also pose a health hazard in the near field. People should not be near the antenna when the radio link is operating as general practice and maintain a safe distance as calculated below. The following calculations are based off the Maximum Permissible Exposure requirements as outlined by the FCC. The MPED (Maximum Permissible Exposure Distance) is calculated based on the limits for a General Population/Uncontrolled Exposure in the 300-1500 MHz frequency band using the stated MPE power density limit of F/1500 mW/cm2 for General population /Uncontrolled environment. To calculate safe distance: Equation 2:      2/(4)(cmmWmtExposureLinAntennaGaiDutyCyclemWowerConductedPMPED Where: MPED is Maximum Permissible Exposure Distance or safe distance in cm All quantities are calculated in linear or numeric quantities. Duty cycle is set using packet sizes for master and slave. Packet sizes are set in the radio Network Configuration Menu. At Power up and with no data transmitting, the radios
5 will transmit or beacon with a duty cycle of 6 to 10% depending upon modulation setting. The worst case exposure limit MPED for 757MHz is shown in the table below.

As such the antenna placement must be done in a manner that is in compliance with all local regulations. All transceivers sold under the FCC ID PEJ-XKJS7 must be installed professionally. This transceiver is only approved for use when installed in devices produced by Xetawave LLC or third party OEMs approved by Xetawave LLC. Antenna Installation Any antenna from a reputable manufacturer with desired bandwidth, gain/pattern coverage, and have an input surge impedance of approximately 50 ohms can be used with the Xeta7. Since professional installation is required, standard RF connectors are used. Adapters or custom coaxial cables may be required to connect the radio output connector to the desired antenna, provided the appropriate requirements are met. Mechanical Interface: The XETA7 has four mounting holes located 0.100 inches from the outside edge of the board as seen below:
6 The four mounting holes have a 0.093” diameter finished opening 0.100” from the edges designed for a #2-56 screw. The clearance height of the radio is 0.210” shield height, .103” PCB height, 0.070” back side height. (The connectors are on the side with the shield.) Heat Sink contact is on the opposite side of the connectors/shield at the lower left corner (back side as shown above).

7 This means that when a 24 pin connector is used to attach a ribbon cable, the pins will be staggered in a non-conventional way. The radio pin out may be connected to two DB9 connectors according to the following pin diagram: Depending upon configuration, before connecting to a computer, each serial port may need to pass through a 3.3V TTL to RS232 converter such as this SerialComm TTL-232-33P. The radio is either manufactured for a high speed 3.3V interface or for a conventional speed RS-232 interface. Radio Ribbon Pin Out 23 24 21 22 … 3 4 1 2
8 In order to power the radio, 7.5V +/- 10% DC must be applied across pins 7 and 10. Communicating with the XETA7 using a serial interface terminal Bits per Second (Baud): 115200 Data Bits: 8 Parity: None Stop Bits: 1 Flow Control: None The computer’s serial port must be configured by the user to match this configuration to communicate. Once the radio is connected to the computer, power may be applied to the radio resulting in the following initialization or boot sequence information being displayed on the terminal: spi_init(SPI_BUS_0) spi_init(SPI_BUS_1) twi_init() iox_init() pll_init(TRUE) interrupt_init() timer_init() mon_init() Xetawave Bootloader revision 1.17.1410 for rev 5 board Booting . . . spi_init(SPI_BUS_0) spi_init(SPI_BUS_1)

Configuring the XETA7 module The minimal steps to configure a radio are: 1) Verify and/or configure the serial port speeds (both diagnostics and data ports) 2) Configure the radio for network operation: a. Master, Repeater, or Slave (one master per network) b. Network operation of “point-to-point” or “point-to-multipoint” c. Network address that is shared by all radios on the network d. Radio address of this radio (“1” if master) e. Address of radio upstream (closer to the Master) f. Address of radio downstream (farther from the Master) g. Set the data block size sent downstream and upstream 3) Set the RF data rate speed and modulation method 4) Set the transmit power 5) Set the distance between the radios for worst case propagation delay.
