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.

Main Host Interface
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.

2.1
Alternate Host Interface
The alternate host interface port provides similar signals to the main host interface. This port may be used for future
development.
2.2
Production Interfaces
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)

Service types
Table 3 describes the service types and their interactions.
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.
