System Overview
Product Description
The 261-3363 Wireless Communication
Adapter (WCA) is a service tool for remotely
monitoring machine or engine operation using
CatET and an 802.11 enabled PC. The group
consists of a portable hardware adapter and a
software program designed to run under
Microsoft Windows (XP, 2000, ME, or 98). It
will allow a laptop computer (PC) to aid in the
monitoring of ECM communication (3) on
J1939/11 high speed data link, CAT DataLink,
and J1708 (ATA) vehicle networks.
Communication between the Wireless
Communication Adapter (2) and the PC with
CatET (1) is transmitted through an 802.11b
wireless network.
The 261-3363 Wireless Communication
Adapter is available as a group that contains
all the necessary cables and software required
for using the Wireless Communication Adapter
on Caterpillar products. Replacement parts
can also be purchased separately. For a list of
the parts contained in the group, refer to the
Parts List section.
1. Laptop computer with Cat Electronic Technician
(CatET). 2. 802.11b wireless network. 3. Wireless
Communication Adapter. 4. ECM.
Wireless Communication Adapter
The Wireless Communication Adapter module
combines the functionality of a Communication
Adapter with an 802.11b radio. The module is
mounted to the machine with magnetic mounts
and connects to the on-board data links (CAT
Data Link, J1939 and ATA) through a Data Link
Harness. The module translates the data link
traffic into messages that are communicated
via the 802.11b Wireless Network to the
802.11b Enabled PC running Caterpillar ET.
Data Link Harness
The Data Link Harness connects the Wireless
Communication Adapter to the diagnostic port
on the radio. Note that the harness length
must not be extended, as functionality will be
lost.
802.11b Enabled PC
Caterpillar Electronic Technician is used on a
PC to display information about the machine.
An 802.11 network card is required for the PC
to communicate with the Wireless
Communication Adapter.
4
Network Interface
The Wireless Communication Adapter system
relies on an 802.11b radio network. The radio
network is configured to operate in Ad Hoc
mode (Channel 11) and utilizes an IP Address
Range in Private Address space (172.23.x.x)
by default but can be changed as needed
based on the site-specific network
requirements. WEP (Wired Equivalent Privacy)
is enabled with a default static WEP key. This
too can be configured based on local
requirements. For information regarding the
modification of settings for the Wireless
Communication Adapter, refer to the Contact
Information section at the front of this manual.
Contact your local Network Administrator for
more information and assistance in changing
and documenting these settings.

Using the Wireless
Communication Adapter
When using the Wireless Communication
Adapter to do remote monitoring of machines,
there are several factors that can have a
significant affect on overall performance of the
system.
1. Location of the Wireless Communication
Adapter on the machine.
2. Location of the PC that will be
communicating with the Wireless
Communication Adapter.
3. Obstacles in the Line-of-Sight between the
PC and the Wireless Communication
Adapter.
4. Weather conditions.
The Wireless Communication Adapter should
be located as high up on the machine as
possible, preferably with the antenna at the
highest point of the machine and adjusted to
point up into the air. Since the Wireless
Communication Adapter relies on
Line-of-Sight for effective communications, it is
important to place the device in a location that
can be easily seen from the location of the PC
that will be monitoring it.
The location of the PC used to monitor the
machine is just as important. If the PC is
sitting on the seat of the service truck, it will be
much less effective in communicating with the
Wireless Communication Adapter than it would
be if it were outside the vehicle in “Line-of-
Site” of the machine. An optional Range
Extender Antenna (see Optional Accessories)
will provide extended range and permit the PC
to be operated where it is not in Line-of-Sight
of the Wireless Communication Adapter, as
long as the Range Extender Antenna can see
the device from its location.
28
Obstacles in the Line-of-Sight between the PC
and the Wireless Communication Adapter can
have a significant affect on the range of the
system. Obstacles may include hills,
buildings, or even the machine being
monitored. If the machine being monitored
drives over a hill, radio communication with the
PC will likely stop until the machine is visible.
Operating the machine with buildings or other
machines in the Line-of-Sight will likely deliver
similar reduction or loss of radio
communication. The machine itself can also
be an obstacle if the Wireless Communication
Adapter is placed on the right side of the
machine and the PC that is monitoring the
machine is on the left. In some cases, while
communication is not completely lost, the
range of the system will be significantly
reduced.
Another factor that can reduce the range of
the Wireless Communication Adapter system is
weather. Range of the system is best on clear,
dry days. Rain and fog will reduce the range
of the system, but will not keep the system
from operating.
It is important to follow these guidelines in
order to achieve the best possible results
when using the Wireless Communication
Adapter.
1. Start CatET and click on “Utilities”, then
“Preferences” on the menu bar to select the
type of Communication Adapter to be used.
This will bring up the following screen.
2. Click on the down arrow to select the
Communication Adapter type. From the list
that is displayed, select “Wireless
Communication Adapter”. When this
selection is made, a second select list will
be displayed that allows the user to select
the Wireless Communication Adapter that is
to be used.
3. If a site has multiple Wireless
Communication Adapter modules, they can
be added through the “Advanced” button
of this menu. The following screen shows a
window that displays several Wireless
Communication Adapters that have been
configured.
29
4. Select the appropriate interface and click
on “OK”. Click on the “Connect” icon to
attempt a connection to the selected
Wireless Communication Adapter. CatET
will display the following window asking you
to verify the selected Wireless
Communication Adapter. If correct, click on
“OK” and CatET will attempt a connection.
If it is not correct, click on the down arrow
of the Wireless Communication Adapter
and select the correct adapter.
NOTE:The following screen is also displayed
upon CatET startup when the last selected
Communication Adapter was Wireless
Communication Adapter.
5. Once the Wireless Communication Adapter
has been selected as the type of
Communication Adapter to be used
(Utilities/Preferences), CatET will try to
connect using Wireless Communication
Adapter on startup of the application. In
order to select a different Communication
Adapter, it is necessary for the user to
“Stop Connect” (or let the connection time
out) and click on “Utilities” then
“Preferences”. Click on the desired
Communication Adapter and click on “OK”.

Troubleshooting Symptoms
Symptom
One or more network applications don’t work
when wireless card is enabled.
Possible Cause
If a network application uses an IP Address
that resides in the address range reserved for
Wireless Communication Adapter, Windows
will try to “route” messages intended for that
network application across the wireless
network. Communications with that network
application will fail whenever the card is
enabled.
Solution
To verify whether or not this is the cause of the
problem, disable your 802.11b card and see if
the network application problem still exists.
Disable the card by:
1. Click on “Start”, “Settings”.
2. Right-click on “Network and Dial-Up
Connections”.
3. Click on “Open”.
4. Right-click on the “Local Area Connection”
that corresponds to the device “Wireless
PC Card Model 0111”.
5. Click on “Disable” to disable the Network
Interface Card for the Wireless
Communication Adapter. If the network
application starts working again, check with
the Network Administrator to consider
possible IP Address changes (of the
