Bluetooth Communications
Note: The following section only applies when the Bluetooth
Module is installed in the PL4 printer.
The radiated output power of this internal wireless radio is far below the FCC radio frequency exposure limits. Nevertheless, this Bluetooth radio must be used in such a manner that the antenna is 2.5 cm (1 inch) or further from the human body such as with a belt clip or shoulder strap. Do not use the printer in an unauthorized manner.
Attention: La puissance de sortie émise par ce module sans fil interne se situe bien
àla radiofréquence stipulées par la FCC. Toutefois, ce module Bluetooth doit être utilisé de façon à ce que l’antenne se situe à 2,5 cm ou plus du corps humain, avec une pince de ceinture ou une courroie par exemple. Utiliser seulement l’imprimante de façon autorisée.
“Bluetooth” is a worldwide standard for the exchange of data between two devices via radio frequencies. Bluetooth radios are relatively low powered to help prevent interference with other devices running at similar radio frequencies. This low power limits the range of a Bluetooth device to about 10 meters (approximately 32 feet).
To exchange data, two Bluetooth enabled devices must establish a connection. Bluetooth software is always running in the background, ready to respond to connection requests. One device (known as the master or the client) must request a connection with another. The second device (the slave or the server) then accepts or rejects the connection. A Bluetooth enabled PL4 normally acts as a slave, but in theory any Bluetooth device can be either a master or a slave. This miniature network is sometimes referred to as a “piconet” and can consist of several Bluetooth enabled devices.
Each Bluetooth PL4 has a unique Bluetooth Device Address (BDA) loaded into its module when manufactured.
