1 Introduction
MWMII (Masimo Wifi Module II) contains an Azureware AW-CM256SM radio module, which
incorporates the Broadcom BCM43455 radio chip. It offers IEEE 802.11 a/b/g/n WIFI with Bluetooth 4.2.
The Wifi radio uses a 50MHz SDIO interface and the Bluetooth radio uses a 3MBaud UART interface.
MWMII has 32.768 kHz Oscillator and 37.5 MHz crystal along with the u. Fl. connector. The radio module
is certified for use with the following two (external) trace antennas: Ethertronics 9000129 and
Ethertronics 1000672.
Bluetooth system is fully compliant to Bluetooth 4.2 and V2.1 that supports EDR of 2 Mbps and 3 Mbps
for data and audio communications. It uses Direct Sequence Spread Spectrum (DSSS), Orthogonal
Frequency Division Multiplexing (OFDM), BPSK, QPSK, CCK and QAM based modulation technologies.
2 Compliance Warnings and Cautions
Caution: Disposal of product - Comply with local laws in the disposal of the device and/or its accessories.
Caution: To minimize radio interference, other electrical equipment that emits radio frequency
transmissions should not be in close proximity to MWMII.
Note: This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
Note: This device complies with Industry Canada’s license-exempt RSSs of the Industry Canada Rules.
Operation is subject to the following two conditions: (1) this device may not cause interference, and (2)
this device must accept any interference, including interference that may cause undesired operation of
the device.
Note: Operation in the band 5150-5250 MHz is only for indoor use to reduce the potential for harmful
interference to co-channel mobile satellite systems.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
