14. In response, “Reply from 172.23.1.31”
messages should display. The IP number
should match the IP address printed on
the Wireless Communication Adapter.
15. If the “Reply from” messages do not
display, repeat the entire installation
procedure. If the “Reply from” messages
still do not appear, refer to the Contact
Information at the front of this manual.
16. If the “Reply from” screen is displayed as
shown above, go to Step 1 of this
procedure (Configure Cat Electronic
Technician for the Wireless
Communication Adapter) and verify the IP
address of the Communication Adapter
you are trying to connect is correct in
CatET. If communication still does not
occur, refer to the Contact Information at
the front of this manual.
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.
