On-Ramp Wireless Confidential and Proprietary 7 014-0057-00 Rev. B 1 Overview The purpose of this document is to provide guidelines allowing an integrator to design a host product that uses the TRN-2013 MCM (Meter Communications Module) and ensures that the system meets all of its technical objectives and requirements. 1.1 On-Ramp Wireless Total Reach Network The On-Ramp Wireless Total Reach Network is comprised of host modules, such as TRN-2013 modules equipped with microNodes, and Access Points (APs). The network operates in the unlicensed 2.4 GHz ISM band. The TRN-2013 circuit board is designed to easily integrate into electric meters, through standard interfaces, enabling robust wireless communication with one or more APs interfaced with a service provider’s local or wide area network.

Meter ANSI and Unintentional Radiator certifications required once integrated into the meter product. Note: Specifications subject to change NOTE 1: During TX mode the supercap charger is disabled to reduce peak currents. NOTE 2: During RX mode the supercap charger is enabled. The supercap charge current is limited to about 110mA. 2.4 Power Supplies The TRN-2013 utilizes two main power supplies when it is functioning: 1. Main switching power supply (3.3VDC output). This main buck-boost power supply is operating at all times. It supplies power to all digital and radio circuits. 2. Supercap Charger (~4.4VDC output). This boost type switching power supply is used to charge the super capacitors. It can only operate with an input supply up to about 4.4VDC. It is in use at all times when primary power is applied. Once primary power is interrupted this power supply is disabled and the super caps supply power to the main switching power supply. Additionally the microNode module on the TRN-2013 printed circuit board has its own switching power supply (buck-boost) that uses, as its source, the main switching power supply of the TRN-2013.

Table 4. ESD Rating ESD Model Class and Minimum Voltage HBM Class 1C ( >1000V) MM Class A (>100V) The antennas have protection in the form of an inductor to ground, thus allowing some robustness to direct ESD strikes. Additionally, the antennas are encapsulated in the polycarbonate housing of the meter – so there is little chance of high voltages on the antennas, or others of the board. 3.3.2 Harsh Environments The TRN-2013 is designed to be an embedded circuit board in an enclosed protective shell. It is not designed to be exposed to outdoor environments without a case or similar protection. An IP 67 or better protective casing is strongly recommended. The polycarbonate dome of the meter nominally provides robustness to harsh environments.
On-Ramp Wireless Confidential and Proprietary 13 014-0057-00 Rev. B 4 Safety Considerations Danger: High Voltages When the TRN-2013 is integrated into the meter, high voltages are present: CAUTION: When the TRN-2013 is mounted in a a Meter, the term “GND” or “Ground” does NOT refer to Earth ground. All signals will have a 120/240/480VAC power superimposed onto those lines. All signals to/from the TRN-2013 need to be isolated. No grounded instruments or computers should touch the TRN-2013 signals. It is recommended to use the following isolation/drivers.

TRN-2013 Integration Specification Regulatory Considerations On-Ramp Wireless Confidential and Proprietary 15 014-0057-00 Rev. B 5.3 EMC Certifications The TRN-2013 is designed to meet regulations for world-wide use. It has EMC modular approval certifications in the United States and Canada. These certifications allow the TRN-2013 to be installed in any final product and only Unintentional Radiator testing is required for the final product. This saves cost and time for System Integrators. The certifications currently achieved are listed in the following table. Other countries will vary. Table 6. TRN-2013 EMC Compliance Certifications Country Certifying Agency Requirement Documents or Paragraph United States Federal Communications Commission (FCC)  15.207 for power-line conducted emissions.  15.215 for TX 20dB bandwidth  15.247 for RF TX 6dB bandwidth, power, conducted and radiated emissions. Canada Industry Canada (IC)  RSS210e includes FCC tests and IC-specific tests (RX radiated emissions, 99% BW). The Grants issued by their respective governments for TRN-2013 are available to System Integrators to ensure that the product has been certified. For more information about these documents, see the list of documents referenced in section 1.2. The integrator of the final product is often required to do additional compliance tests. The integration application and market will determine the specifics. The integrator is advised to consult with local experts in compliance certifications for complete information.  FCC The TRN-2013 is Single-Modular Certified, therefore the final product may only need Class B unintentional radiator and power-line conducted emissions tests. This should be done with the actual production antenna.  Other countries will vary. 5.4 FCC Warnings This device complies with part 15 of the Federal Communications Commission (FCC) Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference. 2.

B requirements, the antenna for this device must be installed to ensure a separation distance of at least 20cm (8 inches) from the antenna to a person. 5.6.1 Product Labels A label showing the FCC ID and IC designators, listed above, must be affixed to the exterior of any device containing the TRN-2013 (if the TRN-2013 is not visible). The exterior label must include: Contains FCC ID: XTE-TRN-2013 IC: 8655A-TRN-2013. The product label is shown in Figure 8. Figure 6. TRN-2013 Product Label 5.6.2 RF Exposure Statement The air interface supports operation on channels in the 2402 MHz – 2476 MHz range for FCC/IC regulatory domains. Before this product becomes operational it must undergo a commissioning procedure, during which critical information required for operation is entered into the device and stored in non-volatile storage. It is during the initial commissioning procedure that the regulatory domain, under which the device will operate, is set. Subsequent configuration of the device during operation is checked against the commissioned regulatory domain and non-permitted channels or transmit power levels are rejected and the device will not transmit until a permissible configuration per the commissioned regulatory domain is set. 5.7 WEEE Directive Neither the TRN-2013 nor the Node is considered “end products” that put them under the WEEE initiatives in the EU. The WEEE directives do not apply to the TRN-2013 product. 5.8 REACH Directive As of August 2012 the TRN-2013 by itself is REACH compliant under 1907/2006/EC. On-Ramp Wireless expects to receive a declaration of conformance from the Taiwan-based manufacturer of the node starting in September 2012. REACH compliance statements are found in Appendix C.
TRN-2013 Integration Specification Regulatory Considerations On-Ramp Wireless Confidential and Proprietary 18 014-0057-00 Rev. B 5.9 RoHS Directive The TRN-2013 and node comply with RoHS directive 2002/95/EC. On-Ramp Wireless has received Certificates of Conformance (CoC) for all components, printed circuit board and contract manufacturers for the TRN-2013 and the Node.

TRN-2013 Integration Specification RF Test Mode Interface On-Ramp Wireless Confidential and Proprietary 20 014-0057-00 Rev. B 7 Provisioning The tools and software required for provisioning the TRN-2013 modules are described in this section. The Provisioning process can be handled in two main ways:  Manual for small runs  Automatic for full production. 7.1 Manual The Node Provisioning Tool (see referenced tools/documents) can be used to provision TRN-2013 boards in small quantity. The PC will attach to the DUT TRN-2013 via its Provisioning header (UART is 3.3V). The TRN-2013 connector is J202 and requires a “TE Connectivity” connector PN 1470364-3 to mate with it. The pin out is:  Pin 1 Debug_RX (3V3 logic)  Pin 2 Debug_TX (3V3 logic)  Pin 3 GND CAUTION: When the TRN-2013 is mounted in an I210 Meter, the term “GND” or “Ground” does NOT refer to Earth ground. All signals will have a 120/240VAC power imposed onto those lines. All signals to/from the TRN-2013 board need to be isolated. No grounded instruments, or computers, should touch the TRN-2013 board signals. Use the setup as described in Figure 2. 7.2 Automatic The automatic process is defined and built by the Customer. On-Ramp Wireless has assisted in the development of these tools but these tools are not the property of On-Ramp Wireless. It is the customer who owns, defines, develops, document, and maintains the Manufacturing Tools. The Provisioning process nominally deals with:  Loading in current versions of Software to microNode and K20 processors  Configuring (channels, TX power, etc.)  Setting and configuring Security Keys (via LKS server)  Performing an OTA test to ensure the complete meter-TRN-2013-antenna chain is verified  Lock down all access ports such as UART header and JTAG. A graphical representation of the provisioning process is shown in Appendix A.
On-Ramp Wireless Confidential and Proprietary 21 014-0057-00 Rev. B Appendix A RF Test Mode Interface The RF Test Modes, described below, are set by setting the "testMode" parameter in the configuration file for the eMCM. A.1 Normal Operating Mode 0 This mode is entered based on a flash configuration setting. This mode is persistent across boots. This is the normal operating mode of the eMCM. UNIL is initialized to communicate with the Node. The meter software layer is initialized to communicate with the meter. Although the eMCM is in its normal operating mode, as determined by the flash configuration setting, other factors may subsequently cause the eMCM to change to a non-normal operating mode (e.g., meter is not in metering mode). A.2 Non-Persistent Idle / Factory Test Mode 1 This mode is entered based on the testMode flash configuration setting. This mode is not persistent across boots (self-clearing). UNIL is initialized to pass-through mode. Meter software layer is not initialized. The UART on the AMR (automatic meter reading) serial interface is placed in loopback mode (using the same baud rate as the meter, e.g., 9600). Same as mode 2 except the flash testMode setting is automatically cleared to mode 0 when entering this mode. A subsequent "set test mode" command can set the cleared value to some other test mode value. A.3 Persistent Idle / Factory Test Mode 2 This mode is entered based on the testMode flash configuration setting. This mode is persistent across boots. UNIL is initialized to pass-through mode. Meter software layer is not initialized. The UART on the AMR serial interface is placed into loopback mode (using the same baud rate as the meter, e.g., 9600). Same as mode 1 except the flash testMode setting is persistent across boots. To exit this mode, the test mode configuration setting must be set to another value which will take effect on eMCM reset. A.4 Non-Persistent Node RF Test Mode 3 This mode is entered based on the testMode flash configuration setting. This mode is not persistent across boots (self-clearing). UNIL is initialized to pass-through mode. The meter software layer is not initialized. Same as mode 4 except the flash testMode setting is automatically cleared to mode 0 when entering this mode. A subsequent "set test mode" command can set the cleared value to some other test mode value.  The TX test mode is controlled by the "txTestMode" parameter in the configuration file.  1 = CW_CENTER  2 = CW_OFFSET  3 = MODULATED
TRN-2013 Integration Specification RF Test Mode Interface On-Ramp Wireless Confidential and Proprietary 22 014-0057-00 Rev. B  The antenna is controlled by the "txTestAntenna" parameter in the configuration file.  0 or 1  The frequency is controlled by the "txTestCenterFreqKhzOffset" parameter in the configuration file.  KHz offset from 2.4 GHz  2000 - 100000  Example: 50000 = 2.45 GHz  The VGA is controlled by the "txTestVga" parameter in the configuration file.  0 - 63, 255  The on/off duration is controlled by the "txTestModeSec" and "txTestModeUsec" parameters in the configuration file. A.5 Persistent Node RF Test Mode 4 This mode is entered based on the testMode flash configuration setting. This mode is persistent across boots. UNIL is initialized to pass-through mode. The meter software layer is not initialized. Same as mode 3 except the flash testMode setting is persistent across boots. To exit this mode, the test mode configuration setting must be set to another value which will take effect on eMCM reset. A.6 Non-Persistent Manufacturing Cal Mode 5 This mode is entered based on the testMode flash configuration setting. This mode is not persistent across boots (self-clearing). UNIL is initialized normally so that it communicates with the Node. The meter software layer is not initialized. The UART on the AMR serial interface is not initialized or used. Same as mode 6 except the flash testMode setting is automatically cleared to mode 0 when entering this mode. A subsequent "set test mode" command can set the cleared value to some other test mode value. A.7 Persistent Manufacturing Cal Mode 6 This mode is entered based on the testMode flash configuration setting. This mode is persistent across boots. UNIL is initialized normally so that it communicates with the Node. The meter software layer is not initialized. The UART on the AMR serial interface is not initialized or used. Same as mode 5 except the flash testMode setting is persistent across boots. To exit this mode, the test mode configuration setting must be set to another value which will take effect on eMCM reset.
TRN-2013 Integration Specification RF Test Mode Interface On-Ramp Wireless Confidential and Proprietary 23 014-0057-00 Rev. B A.8 Non-Persistent Meter Diagnostic Mode (Not Yet Implemented) This mode is entered based on a flash configuration setting. This mode is not persistent across boots (self-clearing). UNIL is initialized normally so that it communicates with the Node. The meter software layer is initialized and communication to the meter is tested and validated. If communication with either the Node or the meter fails (or any other error condition detected), then the red LED is blinked with an error code indefinitely (or until the deployment mode LED timer expires). If no errors are detected, the green LED is blinked normally to indicate network connection state (scanning, joined, etc.). A reset is required to recover. Note: this mode may not be needed if a basic diagnostic or POST check is done by the eMCM as part of its initialization process. A.9 Setting eMCM to Test Mode 1 - Non-Persistent Idle Factory Test Mode How to Enter  Set the 'testMode' flag in the configuration file to one. Example: ./emcm_set_cfg.py -d /dev/ttyS0 --testMode=1  Reset the eMCM to take effect. Example: ./emcm_dev_reset.py -d /dev/ttyS0 --emcm How to Exit  Because this mode is non-persistent, it can be exited via an eMCM reset.  Reset the eMCM to exit the test mode. By default, the eMCM will return to normal operational mode 0 after reset unless another mode was explicitly specified with the emcm_set_cfg.py command prior to resetting. Example: ./emcm_dev_reset.py -d /dev/ttyS0 --emcm  If a different mode is desired upon reset, explicitly Description  UNIL is in pass-through mode.  Meter UART is in loopback mode.  AHP debug port is functional.  Mode is not persistent after resets.

B A.10 Setting eMCM to Test Mode 2 - Persistent Idle Factory Test Mode How to Enter  Set the 'testMode' flag in the configuration file to two. Example: ./emcm_set_cfg.py -d /dev/ttyS0 --testMode=2  Reset the eMCM to take effect. Example: ./emcm_dev_reset.py -d /dev/ttyS0 --emcm How to Exit  Because this mode is persistent, it will remain in effect across eMCM resets.  Set the 'testMode' flag to the new desired mode, e.g., normal operational mode 0. Example: ./emcm_set_cfg.py -d /dev/ttyS0 --testMode=0  Reset the eMCM for the new mode to take effect. Example: ./emcm_dev_reset.py -d /dev/ttyS0 --emcm Description  UNIL is in pass-through mode.  Meter UART is in loopback mode.  AHP debug port is functional.  Mode is persistent across resets. A.11 Setting eMCM to Test Mode 3 - Non-Persistent RF Test Mode How to Enter  Set the 'testMode' flag in the configuration file to three. Example: ./emcm_set_cfg.py -d /dev/ttyS0 --testMode=3  Reset the eMCM to take effect. Example: ./emcm_dev_reset.py -d /dev/ttyS0 --emcm How to Exit  Because this mode is non-persistent, it can be exited via an eMCM reset.  Reset the eMCM to exit the test mode. By default, the eMCM will return to normal operational mode 0 after reset unless another mode was explicitly specified with the emcm_set_cfg.py command prior to resetting.
