Guidance Document
Statement of Agency Compliance
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.
FCC Class B Compliance Statement
The user is cautioned that changes or modifications not expressly approved by the part 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:
•
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 or television technician for help.
FCC RF Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits pursuant to Part 2.1091 for portable devices Part 2.1093 for mobile devices of the FCC regulations.
1. For the PowerScan Base Station users must maintain a separation distance of at least
20cm to nearby persons, set forth in uncontrolled environments, during normal operation as specified in Part 2.1093 for mobile devices.
2. The PBT7100 handheld scanner maximum transmit output is less than 20mW, as specified in Part 2.1091
Canadian Notice
This equipment does not exceed the Class B limits for radio noise emissions as described in theRadio Interference Regulations of the Canadian Department of
Communications.
Le present appareil numerique n’emet pas de bruits radioelectriques depassant les limites applicables aux appareils numeriques de la classe B prescrites dans le
Reglement sur le brouillage radioelectrique edicte par le ministere des
Communications du Canada.
General Description
Datalogic is incorporating a radio module in to the current designs. This module is a complete RF design and no modifications, other then external antennas, are used.
There are two basic systems that integrate this module:
1)
2)
A base station used to deliver transmitted data to a host.
A hand held scanner that transmits barcode data to the base station.
The radio module used in the design is the same for both the base station and the hand held scanner. This module has an antenna port that allows the design to incorporate our own antenna topologies as no antenna is provided with the module.
The module is a Class 1 Bluetooth radio design from Roving Networks using a BC4
CSR Bluetooth chip set. Please see the following datasheet for this module:
The interface to the radio from the on-board processor is identical in both applications using the same base communications format and the exact same pins on the system processor. Both the hand held scanner and base station provide a regulated 3.4VDC to the module as well.
The system uses two different antennas. The base station uses an external whip antenna while the hand held scanner incorporates an internal chip antenna (see picture below):
The antennas used are as follows:
Base Station Antenna
Hand Held Scanner Antenna
