TRN-2012 / TRN-2113 Integration Specification Electrical Interface 3.3.2 Harsh Environments The TRN-2012 and the TRN-2113 are designed to be embedded circuit boards in an enclosed protective shell. It is not designed to be exposed to outdoor environments without a case or similar protection. The casing of the meter nominally provides robustness to harsh environments and has been tested to and meets IP 54 standards. On-Ramp Wireless Confidential and Proprietary 8 014-0047-00 Rev.
4 Safety Considerations Danger: High Voltages When the TRN-2012 or TRN-2113 is integrated into a meter, high voltages may be present: CAUTION: When the TRN-2012 or TRN-2113 is mounted in an SGM3000 series meter, the term “GND” or “Ground” does NOT refer to Earth ground. The SGM3000 is designed to provide isolation to the AMI module (i.e., TRN-2012 or TRN-2113); however, it is recommended to use additional isolation as a precaution.
5 Regulatory Considerations The TRN-2012 uses two integral diversity antennas for half-duplex communication. In contrast, the TRN-2113 uses reverse polarity SMA connectors for external antenna connections. On-Ramp Wireless provides FCC modular approval certification as well as ETSI certification for both models. The two models were used for certification. Documents and test results are available to system integrators for review. 5.
TRN-2012 / TRN-2113 Integration Specification Regulatory Considerations Figure 6. Block Diagram for TRN-2113 with External Antennas 5.2 Antennas The TRN-2012 has been certified to operate with the built-in (PCB chip) antenna (Ethertronics, PN: 1001013) and the TRN-2113 has been certified to operate with the external paddle antenna (L-COM, PN: SP70550). Adherence to these EMC certifications requires that only these antennas be used.
TRN-2012 / TRN-2113 Integration Specification Regulatory Considerations 5.3 EMC Certifications The TRN-2012 and the TRN-2113 are designed to meet regulations for world-wide use. It has EMC modular approval certifications in Europe and South Africa and certification is pending in the United States.
TRN-2012 / TRN-2113 Integration Specification NOTE: Regulatory Considerations This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. WARNING: This equipment generates, uses, and can radiate radio frequency energy.

TRN-2012 / TRN-2113 Integration Specification Regulatory Considerations 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 nonvolatile storage. It is during the initial commissioning procedure that the regulatory domain, under which the device will operate, is set.
6 Installation of TRN-2012/TRN-2113 Boards The TRN-2012 and TRN-2113 boards are simply inserted and removed as shown in the following figures. The two plastic side tabs of the SGM30xx lock the TRN-2012/TRN-2113 module into place and the 12-pin connector is easily guided into the SGM30xx connector by form fit. Figure 10 and Figure 11 show how the TRN-2012 and TRN-2113 boards are mounted inside the GE meter. Figure 10.

7 Operating and Troubleshooting This section provides an overview of the functionality and how best to troubleshoot a module. 7.1 Operating The operating mode of the TRN-2012/TRN-2113 is simple in concept but has many nuances. For a pictorial view of the system, refer to Figure 1. On-Ramp Wireless Total Reach Network. 1. When the TRN-2012/TRN-2113 powers up, it looks for a wireless Access Point (AP). This could take up to a minute or so, depending on a number of factors. 2.

There are two LEDs (Red/Green) on the TRN-2012/TRN-2113 to indicate its status. These LEDs help troubleshoot the status of the TRN-2012/TRN-2113 in a meter. For more information about the LEDs, see Table 9. LED Blinking Patterns/States. 7.
8 Provisioning The tools and software required for provisioning the TRN-2012/TRN-2113 are described in this section. The Provisioning process can be handled in two main ways: Manual for small runs Automatic for full production 8.1 Manual Provisioning The Node Provisioning Tool (see referenced tools/documents) can be used to provision TRN2012/TRN-2113 units in small quantity. The PC attaches to the DUT (device under test) TRN2012/TRN-2113 via its Provisioning header (UART is 3.
TRN-2012 / TRN-2113 Integration Specification Provisioning 8.2 Automatic Provisioning The automatic process is defined and built by the customer. On-Ramp Wireless has assisted in development of these tools but those tools are not the property of On-Ramp Wireless. The customer owns, defines, develops, documents and maintains the manufacturing tools. The provisioning process entails: Loading in current versions of software to microNode and K20 processors; Configuring (channels, TX power, etc.
Appendix A Provisioning Process and Work Flow The following illustration shows a graphical representation of the provisioning process. On-Ramp Wireless Confidential and Proprietary 22 014-0047-00 Rev.
Appendix B Test Mode Interface The test modes, described below, are set by setting the "testMode" parameter in the configuration file for the eMCM. B.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-2012 / TRN-2113 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-2012 / TRN-2113 Integration Specification Test Mode Interface B.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-2012 / TRN-2113 Integration Specification Test Mode Interface B.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-2012 / TRN-2113 Integration Specification Test Mode Interface Description UNIL is partially operational. Meter UART is disabled. AHP debug port is functional. Mode is not persistent after resets. B.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.
