which they operate. Its parameters include country name, channel quantity and maximum transmission level. The country information feature simplifies the creation of 802.11 wireless access points and client devices that meet the different regulations enforced in various parts of the world.

1.7.1 ODIN-W2 IEEE 802.11d implementation description

When ODIN-W2 is used as a Wi-Fi station, the scan is used to detect which regulatory domain it is currently in. Passive scan is used for channels that are not available in all regulatory domains. The device supports the following three domains, where WORLD means all channels that are supported both by FCC, ETSI and most other countries in the world:
• WORLD
• FCC
• ETSI
ODIN-W263 is configured to always support the ETSI domain and is only allowed to be used
in countries allowing ETSI domain channels (see Table 3).
See Table 3 for detailed information on channels that are supported in the different regulatory domains. The state transition diagram below (Figure 2) describes the algorithm for selecting the current regulatory domain.

Initial regulatory domain is WORLD. At start up a scan is initiated to detect beacons containing country information.
If at least one scan result contains country information indicating FCC and no country information indicates ETSI, then the regulatory domain is set to FCC.
If at least three scan results contain country information indicating ETSI and no country information indicates FCC, then the regulatory domain is set to ETSI.
If the scan result contains country information indicating both FCC and country information indicating ETSI, then the regulatory domain is set to WORLD. In the state transition diagram this is the state WORLD_FINAL. This state will not be exited until the device is reset.
A new scan is performed every hour to update the regulatory domain.

2 Interfaces

ODIN-W2 is a surface mounted device (SMD). As the ports supported in the module are not
tested against fast transients, RF common mode, transients and surge, the module must not be connected with cables longer than 3 m.

2.1 Power management

To fulfill EN 60950-1 safety standards, the unit must be supplied by a limited power source.

2.1.1 Module supply input (VCC)

ODIN-W2 series modules must be supplied through the VCC pin by a DC power supply. Voltage must be stable, because during operation the current drawn from VCC can vary significantly based on the power consumption profile of the Bluetooth/Wi-Fi technologies.

2.1.2 Digital I/O interfaces supply output (V_INT)

The ODIN-W2 series modules provide a 1.8 V supply rail output on the V_INT pin, which is internally generated when the module is powered on. The same voltage domain is used internally to supply the generic digital interfaces of the modules. The V_INT supply output can be used instead of an external discrete regulator. See the Electrical specification section for maximum output current.

2.2 Antenna interfaces

The following two different antenna options are available in the ODIN-W2 series:
ODIN-W260 is equipped with dual U.FL. coaxial connectors for external antennas. Different types of external antennas are available and can be used.
ODIN-W262 and ODIN-W263 is equipped with an integrated dual-band antenna
While mounting the unit, ensure that it does not interfere with radio communication. The
ODIN-W262 and ODIN-W263 equipped with an internal surface mounted antenna should not be mounted in a metal enclosure. No metal casing or plastics using metal flakes should be used. Avoid metallic based paint or lacquer.
See the Antennas section for information on the external antennas that can be used and for other RF and antenna design advices. For more info about antenna integration, see ODIN-W2 series system integration manual [1].

2.2.1 Antenna connectors and internal antenna

ODIN-W260 has two RF antenna U.FL. coaxial connectors with a characteristic impedance of 50 Ω. The main antenna connector supports both Bluetooth and dual-band Wi-Fi. The second (MIMO) antenna connector adds support for 2x2 MIMO 2.4 GHz single band Wi-Fi.
ODIN-W262 has an internal dual-band PIFA antenna and supports Bluetooth and dual-band Wi-Fi (SISO).

ODIN-W2 series - Data sheet
Figure 3: ODIN-W260 with connectors for external antennas and ODIN-W262 with an internal antenna

2.3 Data communication interfaces

The ODIN-W2 series provides several data communication interfaces which are described below.

2.3.1 UART interface

ODIN-W2 series modules include a 6-wire UART for communication with an application host processor (AT commands, data communication and software 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)
CMOS compatible signal levels are recommended. For more information about the UART interface, see the u-connectXpress AT commands manual [1] and ODIN-W2 series system integration manual [2].

2.3.2 Ethernet interface

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 full­and half-duplex (CSMA/CD).
UBX-14039949 - R25 Interfaces Page 13 of 53 C1-Public
ODIN-W2 series - Data sheet
The Ethernet interface includes:
• RMII either for MAC to PHY or Ethernet MAC to MAC communication.
• SMI for PHY configuration
The IO voltage of the ODIN-W2 is 1.8 V, which means that the RMII interface operates outside
the RMII specification v1.2. If the RMII is to be connected to a PHY circuit, then that circuit must support 1.8 V operation. If a direct RMII to RMII connection is used, then a level shifter might be needed depending on the selected host. The selected hardware setup must be verified on the application board to guarantee operation.
2.3.2.1 RMII
The RMII uses seven signals in total. The interface requires an external 50 MHz clock source either from a compatible PHY chip or an external oscillator. ODIN-W2 cannot provide this clock signal by itself.
2.3.2.2 SMI (MDC/MDIO management interface)
The two-wire SMI is used to configure the PHY chips. The interface uses a clock line and a data line to clock data to and from the PHY chips registers.

3 System functions

3.1 Module power modes

The ODIN-W2 series module does not have an internal low power oscillator (LPO) which is required for low power modes. An external 32.768 kHz LPO signal can be supplied externally via the LPO_CLK pin if low power modes are required.

3.2 Module reset

The ODIN-W2 series modules can be reset (rebooted) in one of the following ways:
Low level on the RESET_N pin, which is normally set high by an internal pull-up. This causes a “hardware reset” of the module. The RESET_N line should be driven by an open drain, open collector or contact switch.
Using a reset AT command causes a “software reset” of the module, See also u-connectXpress AT commands manual [1]).

3.3 IO signals

3.3.1 System status IO signals

The RED, GREEN and BLUE pins are used to signal the status. They are active low and are intended to be routed to an RGB LED. For more information about connectivity software signal loss, see the u-connectXpress AT commands manual [1].

Data mode IDLE Green LOW HIGH HIGH
Command mode IDLE Orange LOW HIGH LOW

3.3.2 System control IO signals

The following input signals are used to control the system:
RESET_N is used to reset the system. See section 3.2 for detailed information.
If SWITCH_1 is driven low during start up, the UART serial settings are restored to their default
values.
SWITCH_0 can be used to open a connection to a peripheral device.
If both SWITCH_0 and SWITCH_1 are driven low during start up, the system will enter the
bootloader mode.
If both SWITCH_0 and SWITCH_1 are driven low during start up and held low for 10 seconds, the
system will exit the bootloader mode and restore all settings to their factory defaults.
Purple HIGH LOW LOW
Blue HIGH LOW HIGH
For more information about connectivity software signal Ioss, see the u-connectXpress AT Commands Manual [1])

3.3.3 UART IO signals

In addition to the normal RXD, TXD, CTS, and RTS signals, the ODIN-W260/ODIN-W262 software adds the DSR and DTR pins to the UART interface. Note that the DSR and DTR pins are not used as originally intended, but to control the state of the module. Depending on the current configuration, the DSR pin can be used to:
• Enter command mode
Disconnect and/or toggle connectable status
