KOMATSU WIRELESS BRIDGE
(Optional)
General Information
The Komatsu wireless bridge (2, Figure 32-12)
allows for the transfer of information from the
KOMTRAX Plus controller to a laptop computer with
wireless network capabilities. The information that is
downloaded through the KWB (Komatsu wireless
bridge) is the same information that is gathered
during a manual download from the KOMTRAX Plus
system. Downloads can be performed with the laptop
computer located on or near a stationary truck, or the
computer can be located close to a path of moving
trucks. Total download time is approximately 10
seconds. If only a portion of the data is downloaded
while the truck is passing by a laptop computer, the
remaining information will be downloaded the next
time a data download occurs.
The wireless bridge transmits data using antenna (1).
Communication Setup
A computer running a Microsoft® operating system
(with a wireless network adaptor) is required to
download data from the KWB. The individual steps
required are different depending upon the computer
operating system and each computer's specific
wireless adaptor.
Please refer to the computer and/or adaptor manuals
for further details.
1. Ensure that the KWB:
• shows power and function (LEDs illuminated)
• has not been previously setup
• is within range of the computer
2. Use the computer to scan for any available
wireless networks. The computer should find a
network with KWB_SETUP as its SSID (SSID =
Service Set Identifier). If this SSID is present
the KWB is transmitting correctly. Switch to the
KWB_SETUP network.
If the KWB_SETUP SSID is not detected, verify
all connections to the KWB. If all connections
are correct, the KWB will need to be reset.
Reset the KWB by pushing the reset button (2,
Figure 32-15) next to the connector plug.
NOTE: A KWB_SETUP SSID could be transmitted
by another laptop computer and not by the desired
KWB. Power down any other wireless sources with
an SSID of KWB_SETUP.
Switching to the KWB_SETUP Network
The computer should be on the same network as the
KWB. It will be necessary to "create a profile" for the
new network. Check the wireless adaptor's manual
for details.
3. Configure the new profile as follows:
• Set the profile name to KWB_SETUP.
• Set the SSID to KWB_SETUP.
• Select the wireless network type as "ad hoc."
• In the security settings, select "no encryption"
or a similar setting.
• Select channel 11 (most adaptors will
automatically select a channel).
Some wireless adaptor software allows the setting of
a static IP address and subnet mask for each profile.
If this option is available, complete the following
steps:
a. Set the IP address to 192.168.0.xxx, where
xxx is any number between 1 and 255. 123
is recommended if only one computer will be
used to interact with the KWB. If multiple
computers are used, each must be set to a
different IP address.
Set the subnet mask to 255.255.0.0. If asked for a
default gate-way, this may be assigned the same IP
address as the computer.
