22 QL 320 User’s Guide
can manually enter the serial number of the printer; however, this
method is not recommended. The terminal can only capture the
desired printer using this type of link.
The terminal must be programmed to guide the user through
scanning the printer serial number bar-code, then execute an al-
gorithm which converts the serial number into an address. Zebra
can provide C source code to licensed OEM customers that han-
dles the conversion from serial number to address.
Linking From the Printer to the Terminal
When no scanner is available, and/or no additional software is
to be written for the terminal, then the linking operation can be
initiated solely by the printer.
In this procedure the printer broadcasts a message seeking an
available terminal. If a terminal “hears” the broadcast and is
available, it will respond by linking to the printer.
To insure a secure link, the user must perform the link opera-
tion far enough away from other operating terminals so that the
printer does not inadvertently capture some other user’s terminal.
Any other terminal that hears the broadcast message from the
printer may try to link to it, therefore you should insure that only
one terminal is within broadcast range. Feedback is available
from the printer as to the outcome of the link operation.
Bluetooth™ Networking Overview
The following section only applies when the Bluetooth Module (FCC ID: I28MD-BTC2-E)
is installed in the QL320 printer (note that only one of the radio options can be in-
stalled in the printer at one time).
Exposure to Radio Frequency Radiation
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 or further from the
human body.
The radio and antenna are mounted internally in this
printer in such a way that, when the printer is used in a
standard configuration (belt clip, soft case, shoulder
strap), the 2.5 cm distance from the users body will be
met. Do not use the printer in an unauthorized manner.
The internal wireless radio operates within guidelines
found in radio frequency safety standards and
recommendations. The level of energy emitted is far less
