PDA users: install and configure the ROV Scanner Wedge
program designed for your specific type of PDA. If you'll be using
a ROV with ScoutPalDB on a Bluetooth Windows Mobile device, a ROV's Scanner
Wedge setup file is included inside the ScoutPalDB's "spdb2/cab" folder
on the data card. The printed guide that comes with the ROV has further
instructions on how to set up the Scanner Wedge for various devices. You
may also refer to the manufacturer's website at
for more information and
Windows computer connection:
A hardware connection from a ROV to a Windows computer can be made over
Bluetooth Radio or through a serial port. Either connection type will
need to be carefully set up in order to work at all. Most users
will likely prefer to use a wired serial connection.
** If you use Windows 8 or Windows 8.1, you will definitely find it easier
to control driver and wedge software if you first set up the free
Classic Shell. It will make
your Windows 8/8.1 desktop and start button look and feel more familiar,
and restore full control over how you download, install, place, and run
Some computers with built-in or add-on Bluetooth may be compatible with
a Bluetooth connected ROV, but only if the computer's Bluetooth system uses
Widcom Bluetooth stack.
Because Bluetooth connections are often difficult to establish and
maintain, most users will prefer to connect a ROV to a computer using its included
serial cable, plugged into a separately purchased USB-to-Serial adapter. These adapters are widely available online, at Radio Shack, and at computer
stores. You will need a USB-to-Serial adapter that's compatible with
your operating system. Just as you should always do with any
type of accessory hardware, BE SURE to always install the adapter's PROPER
driver first, before plugging it into a USB port.
As with any sort of accessory, there are many USB-Serial adapters to
choose from, but we have found that adapters using a Prolific PL2303HX Rev
D (PL-2303HXD) chipset can nearly always be configured to work with
all the different Windows operating systems. Specifically, we have
seen the "TRENDnet USB 2.0 to RS-232 DB9 Serial Converter, TU-S9" work with
all kinds of Windows machines, including Windows 8 & Windows 8.1!
The TRENDnet TU-S9 uses a Prolific PL-2303HXD chipset. Here is an
example Amazon query for a TRENDnet TU-S9 adapter:

Note: When serially connecting a ROV you can disable its radio so that
it no longer constantly drains the AAA batteries. (Most ROV's
have a Bluetooth radio chip inside their battery cover.) A simple
way to do this is to place a piece of tape over the Bluetooth contact pads
that are inside the scanner's battery compartment. This will safely
prevent the Bluetooth cover's contact pins from making electrical contact.
Once you have the adapter installed and using its driver, (be sure to
install the adapter's driver before plugging it in to a USB port
for the first time), you'll need to know which COM port number it uses.
If properly installed, it will show up in the Windows Device Manager as
a COM Serial Port, its entry in the Device Manager list will show no issues
(question marks and/or exclamation points indicate driver problems), and
its entry will also display which COM port number it uses.
The Prolific driver typically installs itself on COM3. If you find need
to change the adapter's default COM port number, you can do that with the
port's settings/advanced settings button in its right-click properties window.
(If you don't know how to launch and use Windows Device Manager, you can
find tutorials from the wealth of information on the internet: google, youtube,
You'll also need a software "wedge" program capable of intercepting ROV
scan packets from the adapter's serial port, and injecting them into whatever
program you may be running at the time of the scan. The wedge program
will need to be configured properly, as well as be running and connected
to the ROV through the COM port in order to inject your scans.
You will find links to various wedge programs on our
ROV Order page, the basic versions are
free. Read the wedge descriptions carefully and choose one most suited to
your equipment and needs. After installation, the wedge program will
need to be configured for the serial characteristics of the ROV. With
some wedges, you'll only need to let it find or specifically tell it the
adapter's COM port number. Other wedge programs may need to have detailed
serial parameters set that are specific to the ROV: 4800 baud, no parity,
1 stop bit, 8 data bits, no handshake, aka
4800/8-N-1. You may
also need to configure the wedge to translate CR to an ENTER key.
Once all the above configuration steps are finished, and while the Wedge
is running, the ROV will transparently send its scans directly and nearly
instantly into whatever program you are running at the time you scan, just
as if you typed the barcode digits in from a keyboard at lightning speed.
