Page 3 of 6 1 Purpose This document serves as the manual for the EnergyHub daughtercard to be used only in EnergyHub devices as specified by this document. 2 Introduction Each EnergyHub peripheral device contains a comm board. This board serves as the communication interface for the EnergyHub system. Each device within the EnergyHub network uses one of these devices to communicate with the Home Base which gathers information about the use of energy in a user’s home. 3 Electrical Connector Interface Connectors P3 and P4 are the main connection from the EH Communications board. The power and signals between the EH communication board and the host interface are carried through this connection. The connectors on the Comm Board are 2mm pitch, 2 row 16 pin receptacle connectors. The Dashboard interface has two 16 pin headers. Figure 3 shows a picture of the connections on the bottom of the communication board.

Operation is subject to the fol- lowing two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. See instructions if interference to radio or television reception is suspected. Radio and Television Interference This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in Part 15 of FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the equipment. If your equipment does cause interference to radio or television reception, try to correct the interference by using one or more of the following measures:  Change the position of the television or radio antenna until the interference stops. …

Professional Testing (EMI), Inc. 1601 FM 1460, Suite B Round Rock, Texas 78664 May 11, 2011 On behalf of EnergyHub, Inc., Professional Testing (EMI), Inc. is seeking a modular approval for the Zigbee Daughter Card. Requirements listed in FCC part 15.212 and Section 3.2.2 of RSS-Gen Issue 3 are addressed below. 1) The device has a RF shield covering the RF generating portion of the circuit board. 2) The external data inputs are buffered with FIFO data buffering. 3) The module is powered from a self contained switching power source that converts AC voltage to 5 VDC. An internal regulator converts 5 VDC to 3.3 VDC. 4) The antenna requirement is satisfied by the use of a PCB plane inverted antenna. 5) The module was tested in a stand-alone configuration, free of an enclosure. 6) A sticker is affixed to the back side of the . The manual contains the explicit directions to label the exterior of the device into which the RADM-ZP is integrated with “Contains FCC ID: ZANEHZPA20”. 7) The Users Manual explains that any modifications may strictly void the certification and a separate approval must be obtained. 8) Emissions are far below the RF Exposure limits.
