Elpro Technologies E2-450 Radio Transceiver Module Instruction Manual 2 www.cooperbussmann.com/wirelessresources Rev Version 1.0 ATTENTION! Incorrect termination of the supply wires may cause internal damage. Before turning the power on double-check ALL connections by referring to this User Manual. CAUTION To comply with FCC RF Exposure requirements in section 1.1310 of the FCC Rules, antennas used with this device must be installed to provide a separation distance of at least 90 cm from all persons to satisfy RF exposure compliance. DO NOT Operate the transmitter when anyone is within 90 cm of the antenna. • Operate the transmitter unless all RF connectors are secure and any open connectors are properly •terminated. Operate the equipment near electrical blasting caps or in an explosive atmosphere. •All equipment must be properly grounded for safe operations. All equipment should be serviced only by a qualified ELPRO staff only. FCC Notice: Part 90 – This device has been type accepted for operation by the FCC in accordance with Part90 of the FCC rules (47CFR Part 90). See the label on the unit for the specific FCC ID and any other certification designations. Note: This device should only be connected to Devices that are covered by either a FCC DoC or are FCC certified.

Elpro Technologies E2-450 Radio Module Instruction Manual Rev Version 1.0 www.cooperbussmann.com/wirelessresources 5 CHAPTER 1 - INTRODUCTION The E2-950 is a radio modem module that will be used as a base radio for a number of Elpro wireless products in the future. It will be primarily used to act as a wireless network adapter for transfer of 802.11 data frames over lower speed wireless links. The E2-950 consists of a host microcontroller, an RF transceiver section, and a power supply section. CHAPTER 2 - Module Description Main Host Interface 2.0 The main host interface is delivered through a 20 pin standard right angle pin header connector indicated in the picture above. The pin description will be described in chapter 4. This interface provides power supply to the module. This interface also provides a serial interface to the module where data can be supplied to be transmitted and received through. Alternate Host Interface Production Interfaces Main Host Interface Grounded Mounting Holes
Elpro Technologies E2-450 Radio Module Instruction Manual 6 www.cooperbussmann.com/wirelessresources Rev Version 1.0 Alternate Host Interface 2.1 The alternate host interface port provides similar signals to the main host interface. This port may be used for future development. Production Interfaces 2.2 The production interfaces consists of JTAG ports and serial interfaces directly to microcontrollers. These interfaces are used in production and development only. CHAPTER 3 - OPERATION The host system communicates with the E2-950 module via the serial interface provided by the main host interface. The serial interface is a standard TTL UART interface in full duplex asynchronous connection. The baud rate is 1.0Mbps. RTS and CTS lines are used to provide flow control between the host and radio processors. The serial protocol is a proprietary message structure. Message Framing Message framing is based on PPP Byte stuffing. The special characters 0x7F, 0x7D and 0xFF are the beginning of a frame, data link escape and end of frame characters respectively. Each message begins with the transmission of the start of frame character. This is followed by the message data payload for the message end of the message is indicated by the end of frame character. Occurrence of the characters for start of frame, end of frame, or the data link escape character within the data packet is indicated by stuffing an additional data link escape character into the data stream before the special character and then setting bit 5 of the control character to 0. Whenever the start flag character is detected, the framer state is reset to receiving the first data payload byte. (Start flag should never occur in the data payload due to the escaping scheme above.) The end of frame character ensures that the transmitter and receiver are synchronised at the beginning of the next data frame. If they are not correctly synchronised, the 0xFF will result in the additional “ones” being detected as a long stop condition at the receiver and subsequent characters being correctly synchronised. Message Format Endian All multi-byte fields are transmitted in little endian format. General Message Format Table 1 describes the general format of the messages including the start and end flags. START_FLAG 1 byte Start of message identifier (0x7E) Service_code 2 bytes Service code to identify message type and message ID Payload Data 0-n bytes Message payload data. Interpreted according to Service code END_FLAG 1 byte End of message identifier (0xFF) Table 1: General message format

Request (0b00) Request messages are used where a message acknowledgement is required. A confirm message is expected to be sent from the other party. Matching of request and confirm messages depends on the message ID. Messages may include a unique handle to that can used to match request to confirm, or the process transmitting the message can ensure that only one message of that type is outstanding at any time. Indicate (0b01) Used when acknowledgement of the message is not required. Indicate messages do not have any matching confirm message. Confirm (0b10) Confirm messages are returned to the process that initiated a Request message to acknowledge receipt of the request message (and possible acknowledge processing of the request message is complete). Generation of the Confirm message and the details of any payload data depend on the Service ID for the message. The Service ID for the confirm must match the service ID for the original request message. Table 3: Service types For more detailed information about the protocol, refer to ELPRO document; spec_E2-Radio-io-protocol_V2-5.doc.
