Advanced Configuration and Operation
standard. The devices communicate via simple RF signals so that the communica-
tion is practically independent of the manufacturer and the software being used.
Many Targa computers already feature an internal IEEE 802.11 standard WLAN
adapter by default and are therefore suitable for wireless communication. Please
see the datasheet showing its technical specifications to see if your particular model
already supports this feature. In order to be able to use a WLAN, you will also need
another computer answering to your RF signals. But this should not represent any
real problem. If you have another PC or a notebook, you can install a WLAN adapter
and set up a wireless connection with just a few clicks.
If you only need to interconnect two computers, this procedure is very fast and easy
via a so-called Ad-Hoc connection. You can set up this kind of data connection in a
few minutes. Theoretically you can also connect more than two computers using the
Ad-Hoc mode. However, this mode is not intended for this type of application and it
will handle larger volumes of data and complex network architectures with difficulty.
When connecting several WLAN computers in a network, a so-called Access Point
or WLAN router is recommended. These devices represent a common node or
distribution box in the network and manage its traffic. Therefore, an Access Point or
WLAN router works in the same manner as a hub or router in a cable network. All
WLAN adapters are usually compatible with these devices. Therefore, you can
integrate your computer into an existing wireless network with Access Point and/or
WLAN router without any problem.
If you have another computer with a WLAN adapter installed, you are ready for the
network configuration. You must give the corresponding access and network
information to your computer, similar to the procedure necessary for a cable net-
work. This is not difficult and you will be able to perform it in just a few steps.
Connecting to an Existing WLAN, e.g. Router
If you want to integrate your Targa computer within an existing WLAN, Windows
Vista
®
allows you to do this with ease. For this, it is necessary that the network has
already been configured, i.e. the RF communications already work. This will be the
case, for instance, when using a WLAN router that has been setup to be accessed
from your local network. In this case, there will be no problem to establish a WLAN
connection. Proceed as follows to setup the connection:
1.
As soon as you plug in your computer’s WLAN
adapter Windows will start searching for any existing
wireless connections. Once a wireless network has
been detected, an icon will appear in the notification
area at the lower-right corner of the task bar. It may
take a while for Windows to locate a new network. This
