Page 4 of 14 man_E2-455_V1-4_with_Part15_RSS E2-455 User Manual 1 Introduction The E2-455 is a radio modem module used as a base radio for a number of Elpro wireless products, with additional products to be added in the future. It operates as a wireless network adapter for transfer of 802.11 format data frames over lower speed wireless links. The E2-455 consists of a host microcontroller, an RF transceiver section, and a power supply section. 2 Module Description Under Side View Heat Sink Block Host Interface Mounting Earth Points Top Side View Console Production Interface Host Interface Alternate Host Interface Page 5 of 14 man_E2-455_V1-4_with_Part15_RSS E2-455 User Manual 2.1 Mounting Points Four mounting points are provided for 2.5mm Mounting screws. 2.2 Heat-Sink Block A Heat-Sink should be connected to the devices Heat-Sink block to prevent the power amplifier overheating. The interface to the Heat-Sink block uses two M3 screws separated by 15mm, with engagement depth between 3mm-4mm. Use heat-paste or other heat-conducting material to provide an effective heat conduction path from the heat-sink block to the supplied heat-sink. 2.3 Main Host Interface The main host interface is implemented through a 24-pin socket, allowing connection to standard 0.1 pitch headers. This interface supplies power to the module as well as the high speed serial connection providing communication to the host device. 2.4 Alternate Host Interface The alternate host interface provides the same functionality as the Main host interface, in a more compact form-factor for use with products requiring a more compact interface. 2.5 Production Interface Production interface consists of a JTAG port for programming and developer debug of the device. 2.6 Console Interface The Console interface allows connection of a serial terminal to the device for diagnostic operation and testing. 3 Locale The E2-455 is available in two models, supporting frequency bands 340-400MHz and 400-480MHz. Model E2-455-445 E2-455-375 Frequency Band Supported Channel Bandwidth 400-480MHz 340-400Mhz 6.25kHz, 12.5kHz, 25kHz 6.25kHz, 12.5kHz, 25kHz The host software shall implement Locale settings to restrict the range of frequencies, bandwidths and power relevant to the regulations of the specified locale. The user manual of the product shall state that the unit is to be installed by professional personnel. 3.1 United States Locale The following restrictions on each of the bands apply when US Locale is selected:
Model Locale Frequency Band Supported Channel Bandwidth E2-455-445 FCC_Part90 421MHz 480.000MHz 6.25kHz, 12.5kHz E2-455-375 Not Available Not Available 4 Operation The host system communicates with the E2-455 module via the serial interface provided by either the main or alternate 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. In addition, a secondary diagnostic interface is provided over the Console interface. This provides the interface for testing the device. It operates at a rate of 115,200 baud. 4.1 Diagnostic Interface Command Reference 4.1.1 Radio Commands General Set to QAM Mode (Note: par rate command must be re-issued) Page 6 of 14 man_E2-455_V1-4_with_Part15_RSS E2-455 User Manual

[1] Average RSSI = 0 dB Average over all received BER frames
[1] Average LQI = 0 Average over all received BER frames 4.2 Host Interface 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. 4.3 Host Interface Message Format 4.3.1 All multi-byte fields are transmitted in little endian format. Endian 4.3.2 Table 1 describes the general format of the messages including the start and end flags. General Message Format 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 4.3.3 Table 2 describes the encoding of the Service code field from the Service Type and Service ID Service code encoding b15 - b14 Service Type 00: request 01: indicate 10: confirm 11: unused b13 - b0 Service ID 0x41: Transmit 0x42: Flush 0x43: Receive 0x44: Local_Management 0x45: Extended Transmit 0x46: Extended Flush 0x47: Extended Receive Table 2 4.3.4 Table 3 describes the service types and their interactions Service types Page 9 of 14 man_E2-455_V1-4_with_Part15_RSS E2-455 User Manual Request
(0b00) Indicate
(0b01) Confirm
(0b10) Table 3 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. Used when acknowledgement of the message is not required. Indicate messages do not have any matching confirm message. 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.
