(216) 245-4180 2 LoRa Data Concentrator 8-Path North America Radio USER MANUAL Card Features High Performance LoRaWAN Data Concentrator Card North America 915MHz Sub-GHz ISM Band Semtech SX1301 Radio Chip Semtech SX1257 Transceivers High Node count support Selectable SPI or USB Interface USB Debug Port Low Power Description The EPM2M-LORA-DC-8-NA Radio Card is a LoRa Data Concentrator Radio for use in LoRaWAN packet forwarding gateways. The radio Card is based on the Semtech SX1301 Base Band Processor and the SX1257 Radio Transceiver. Both SPI and USB interfaces are provided for easy interfacing to processor based systems. The Card acts as a data Concentrator of LoRa packets received from remote radio Cards. This Card also transmits data to remote radio Cards allowing for two-way control of remote devices. The radio Card nominally operates in the 915MHz ISM band in uplink and downlink paths.

(216) 245-4180 3 LoRa Data Concentrator 8-Path North America Radio Card USER MANUAL Operation The EPM2M-LORA-DC-8-NA supports the LoRaWAN Protocol. Reference this protocol for specific operational details and additional information. The SX1301 provides the wireless baseband processing for the Card. It receives digitized bitstreams from the SX1257 transceivers. The SX1301 adaptive demodulators receive the packets and stores them in a FIFO. This stored data is available to the host via the host interface. Received packets can be time-stamped using a GPS input. During Transmission, the data pakets are modulated and sent through the transceivers as required. Software Considerations The radio Card receives microcode downloaded from the host via the host interface. The radio Card interface control is made through a Hardware Abstraction Layer (HAL). This code is available from Embedded Planet. Electrical Characteristics Transmit Frequency Range(s):

(216) 245-4180 9 LoRa Data Concentrator 8-Path North America Radio Card FCC REGULATORY STATEMENTS Model US/FCC EPM2M-LORA-DC-8-NA USER MANUAL The OEM must follow the regulatory guidelines and warnings listed below to inherit the Embedded Planet modular approval. The EPM2M-LORA-DC-8-NA holds full modular approvals and has been certified for integration to products only by OEM integrators under the following conditions:
1. The antenna(s) must be installed such that a minimum separation distance of 20 cm is always maintained between the radiator (antenna) and all persons. 2. The transmitter module must not be operating in conjunction with any other antenna or transmitter, except in accordance with FCC multi-transmitter product procedures. If the two conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). IMPORTANT NOTE: If these conditions cannot be met (for certain configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID Certification Number cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. Power Exposure Information Federal Communication Commission (FCC) Radiation Exposure Statement:
To comply with FCC RF exposure limits for general population/uncontrolled exposure, the antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and operating in conjunction with any other antenna or transmitter.

However, the type size for the text is not required to be larger than eight point. CAUTION: The OEM should have their device which incorporates the EPM2M-LORA-DC-8-NA tested by a qualified test house to verify compliance with FCC Part 15 Subpart B limits for unintentional radiators. WARNING: Changes or modifications not expressly approved by Embedded Planet could void the users authority to operate the equipment. Regulatory Statements 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. This equipment generates, uses, and can radiate radio frequency 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 an installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to correct the interference by one or more of the following measures:
Re-orient or relocate the receiving antenna Increase the separation between the equipment and the receiver Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. support@embeddedplanet.com 4760 Richmond Road Suite 400 Cleveland, OH 44128 11 P5010000139RC00
