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 users 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.

The maximum available current draw to the daughtercard board is 200mA. 3.2 Serial Communications Interface 3.2.1 UART1 The UART logic high voltage is 3.3V Pin P3-13 for the TX1 pin has a 10K pullup on the host interface Pin P3-16 for the RX1 pin has a 10K pulldown on the host interface The default baud rate is 38400. It can be modified in firmware to adapt to the host module. 3.2.2 UART2 The UART logic high voltage is 3.3V The confidential information contained within this document is the property of EnergyHub, Inc and may not be duplicated, used, disclosed, or distributed without the written consent of EnergyHub, Inc. Page 4 of 6 Doc Title Communication Board Manual Doc Number ENG-SPEC-MNL-1040 Rev 1 Doc Type Product Manual Department Engineering Pin P4-13 for the TX2 pin has a 10K pullup on the host interface Pin P4-14 for the RX2 pin has a 10K pulldown on the host interface CTS2 and RTS2 are active low. The default baud rate is 38400. It can be modified in firmware to adapt to the host module. 3.2.3 I2C The I2C voltage is 3.3V The I2C requires 4.7k Ohm pullups on the host board. 3.2.4 SPI SPI logic voltage is 3.3v Daughter card shall be configured as the slave device. 4 Industry Compliance 4.1 FCC Compliance Statement This device complies with part 15 of the FCC rules. 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. Move the equipment to one side or the other of the television or radio. Move the equipment farther away from the television or radio. Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the computer and the television or radio are on circuits controlled by different circuit breakers or fuses.) If necessary, consult an experienced radio or television technician for help.

This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Le prsent appareil est conforme aux CNR dIndustrie Canada applicables aux appareils radio exempts de licence. Lexploitation est autorise aux deux conditions suivantes: (1) lappareil ne doit pas produire de brouillage, et (2) lutilisateur de lappareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible den compromettre le fonctionnement.
