Data communication interfaces
The ODIN-W2 series provides several data communication interfaces which are described below.
2.3.1
UART interface
The ODIN-W2 series modules include a 6-wire UART for communication with an application host processor (AT
commands, Data communication and firmware upgrades).
The following UART signals are available:
•
Data lines (RXD as input, TXD as output)
•
Hardware flow control lines (CTS as input, RTS as output)
•
Link status (DTR as output, DSR as input)
It is recommended to use CMOS compatible signal levels. See
ODIN-W2 AT Commands Manual [1]
ODIN-
W2 series System Integration Manual [2]
for more information about the UART interface.
2.3.2
Ethernet interface
Support for an Ethernet interface is planned for version ODIN-W26x-01B-00.
The ODIN-W2 series modules include an integrated Ethernet MAC to communicate with other networked nodes
over a shared medium. It supports 10/100 Mbit/s communication and can operate in both full- and half-duplex
(CSMA/CD).
The Ethernet interface includes:
•
RMII either for MAC to PHY or Ethernet MAC to MAC communication.
•
SMI for PHY configuration
