Bluetooth ® Interface - Printekmobile FieldPro RT43 Series Operator's Manual

Interfacing to a Host Computer
Figure 14 and Figure 15 show the location of the Universal Port Connector and the connector pin assignments.
Caution: Do not make any connection to pins 4 or 8. These pins are used only for Printek accessories and
improper connections with these contacts may cause severe damage to the printer. Such damage will
not be covered by the printer's warranty.
In addition to the standard Serial Interface, your FieldPro RT43 may be equipped with an optional Bluetooth
Interface. Bluetooth interfaces are built into some Smartphones and PDA's and may be added to most others.
Bluetooth interfaces may also be added to notebook or desktop computers. To communicate using the
Bluetooth Interface, it must be selected as the currently active interface.
The Bluetooth Interface uses wireless, radio frequency signals to communicate.
The FieldPro Bluetooth Interface acts as a "serial port adapter" operating as a "server". Being a serial port
adapter means that the printer may appear as a "Serial Device" when discovered, rather than as a "Printer".
