Appendix D – Using the Wi-Fi Interface
In addition to the standard Serial Interface, your FieldPro RT43 may be equipped with an optional Wi-Fi
Interface. To determine if this interface is installed in your printer, you may look at the model description on
the serial number label on the back of the printer. You may also refer to "Performing A Printer Self Test" on
Page 6.
The Wi-Fi interface uses wireless, radio frequency signals to communicate. Wi-Fi interfaces are built into some
PDA's and may be added to most others. Wi-Fi interfaces may also be added to notebook or desktop computers
and as an "access point" to a wired network. To communicate using the Wi-Fi Interface, it must be selected as
the currently active interface.
The FieldPro Wi-Fi interface acts as a server and will accept connections from a host device such as a PDA,
notebook computer, or a network server.
When operating in Infrastructure mode, the printer will attempt to conserve battery power whenever possible by
placing the Wi-Fi interface into a low power mode when not communicating. However, according to the IEEE
802.11b standard, the printer must be granted "permission" from the network's Access Point before operating in
the low power mode. Since different Access Point manufacturers implement this feature differently, the amount
of power saving actually achieved varies. The actual power saving also varies with the amount of network
traffic.
In order to use the Wi-Fi Interface, it must be the currently "selected" interface. To determine if the Wi-Fi
Interface or the Serial Interface is selected, you may either perform a printer self test as described on page 6, or
you may perform the following procedure.
1. Make sure the printer is powered on.
2. Press and hold the Paper Feed button until a second "beep" is heard and then release the button.
3. The set up parameters for the currently selected interface will be printed. If the items printed are as
shown below, the Wi-Fi Interface is selected and you may skip the remaining steps.
