The HS-DWAM82IA module is the wireless audio transceiver module. The module holds the
radio transceiver IC, the DARR82 digital audio baseband processor and associated components
and circuitry .
The HS-DWAM82IA platform can host many different applications ,requiring different external
components ,as a frame of reference ,for a simple stereo uni-directional audio link ,need to
external components are required.
Basic Features:
--Low latency ( configurable from <20ms )
--In-room or multi-room usage (point to multi-point is also supported )
--Bi-directional data channel
--Automatic frequency allocation
--Automatically controlled transmitter / receiver antenna spatial diversity minimizes fading and
multipath effects.
Pairing function :
all units in the same wireless audio network are provided with a 16bit network ID,shielding the
network from neighbor audio networks.
The HS-DWAM82IA is used for both the transmitter and receiver .The module is configured
either through the I2C interface ,through the EEPROM or through the optional microcontroller.
REMINDING
Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
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:
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.
—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.
To satisfy FCC RF exposure requirements, a separation distance of 20 cm or more should be
maintained between the antenna of this device and persons during device operation.
To ensure compliance, operations at closer than this distance is not recommended.
Under Industry Canada regulations, this radio transmitter may only operate using an
antenna of a type and maximum (or lesser) gain approved for the transmitter by
Industry Canada. To reduce potential radio interference to other users, the antenna
type and its gain should be so chosen that the equivalent isotropically radiated power
(e.i.r.p.) is not more than that necessary for successful communication.
This radio transmitter has been approved by Industry Canada to
operate with the antenna types listed below with the maximum permissible gain and
required antenna impedance for each antenna type indicated. Antenna types not
included in this list, having a gain greater than the maximum gain indicated for that
type, are strictly prohibited for use with this device.
Antenna type: PCB antenna
Max gain: 1dBi
Antenna impedance: 50ohm
