Communicate Data to Off-Board Systems
The VHMS has two methods to communicate data to
off-board systems:
• Via satellite to the WebCARE database
• Download to a laptop PC running the VHMS
Technical Analysis Toolbox software
Communication to the satellite (using OrbComm)
occurs automatically, but only sends critical data
items. OrbComm controller (1, Figure 11-1) is
located inside the auxiliary cabinet. OrbComm
antenna (1, Figure 11-3) is mounted on the front left
corner of the cab by magnetic mount (2).
Communication to a laptop PC occurs whenever a
user connects a laptop PC to the VHMS controller
and requests a data download. All VHMS data is
available for download to a laptop PC. Once down-
loaded to a laptop PC, the information is then sent to
Komatsu via FTP. This data is then compiled at the
Komatsu computer server. Based on this information,
the local Komatsu distributor will suggest improve-
ments and provide information aimed at reducing
machine repair costs and downtime.

In order to collect all the necessary machine data, a
preventative maintenance (P.M.) snapshot needs to
be recorded every 500 hours of operation. The snap-
shot and other data is then downloaded into a laptop
PC. This data is to be sent to Komatsu via the FTP
program which is a part of the VHMS Technical Anal-
ysis Tool Box program. Refer to the check-out proce-
dure for more detailed information regarding a P.M.
snapshot.
