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.
TRN-2013 Integration Specification Overview 1.2 Referenced Documents The following documents are referenced and provide more detail: TRN-2013 FCC and IC EMC Compliance Grants These are the Regulatory Grants issued by their respective governments. Provisioning Guide (010-0074-00) Describes setup, configuration, and use of a collection of utilities called Node Provisioning Tools (NPT) used for Node provisioning.

3 Electrical Interface This chapter describes the electrical interface of the TRN-2013. 3.1 Signal Connectors Both sides of the TRN-2013 printed circuit board are shown below. Figure 2. TRN-2013 Printed Circuit Board On-Ramp Wireless Confidential and Proprietary 11 014-0057-00 Rev.
TRN-2013 Integration Specification Electrical Interface 3.2 Pin and Signal Descriptions The following table lists the pins and signals for the J500 connector. Table 3. Pins and Signals for J500 Signal and Power Connector MCM Pin # Pin Name Signal Description 1 TX Transmit signal from Meter 2 RX Receive signal from Meter 3 GND Signal ground (not Earth ground) 4 VCC AMI power input; 3.3VDC nominal.
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.
5 Regulatory Considerations 5.1 Block Diagram Some regulatory domains require a block diagram of the module for their documentation similar to that shown in the following figure. Figure 5. TRN-2013 Block Diagram 5.2 Antenna This device has been certified to operate with the built-in (PCB chip) antenna listed below. Adherence to these EMC certifications requires that only this antenna be used.
TRN-2013 Integration Specification Regulatory Considerations 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.
TRN-2013 Integration Specification WARNING: Regulatory Considerations This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in accordance with the instructions, this equipment may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
TRN-2013 Integration Specification Regulatory Considerations 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.
TRN-2013 Integration Specification Regulatory Considerations 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. Copies of the CoCs are stored at On Ramp Wireless and available upon request. On-Ramp Wireless Confidential and Proprietary 18 014-0057-00 Rev.
6 Installation of TRN-2013 Board The following figure shows how the TRN-2013 MCM is mounted inside the meter. Three screws (P/N 9925887027, #4-24X.31 self-tapping, type BF Phillips pan-head steel zinc screw) are required to mount TRN-2013 in place. The recommended torque values for the screws are 6 to 7 in.-lbf. Three mounting screws Figure 7. Meter Assembly with a TRN-2013 MCM On-Ramp Wireless Confidential and Proprietary 19 014-0057-00 Rev.
TRN-2013 Integration Specification RF Test Mode Interface 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 TRN2013 boards in small quantity. The PC will attach to the DUT TRN-2013 via its Provisioning header (UART is 3.3V).
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.
TRN-2013 Integration Specification 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.
TRN-2013 Integration Specification RF Test Mode Interface 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.
TRN-2013 Integration Specification RF Test Mode Interface 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.
TRN-2013 Integration Specification RF Test Mode Interface Description UNIL is partially operational. Meter UART is disabled. AHP debug port is functional. Mode is not persistent after resets. A.12 Setting eMCM to Test Mode 4 - Persistent RF Test Mode How to Enter Set the 'testMode' flag in the configuration file to four. Example: ./emcm_set_cfg.py -d /dev/ttyS0 --testMode=4 Reset the eMCM to take effect. Example: ./emcm_dev_reset.
