Logging to USB Flash Drive Via USB Host Cable
The [LOGFILE] command used in this procedure does not work with USB flash drives
that have a write-protected primary partition. The partition will not mount properly. The
most common examples of this are drives with U3 software installed. In order to log
using these drives, this partition must be removed. Reformatting the drive is not
sufficient. According to the U3 web site:
“Most U3 smart drives come with an uninstall utility that converts the U3 smart drive into
a regular USB flash drive. This utility can be accessed from the U3 Launchpad. Open
the U3 Launchpad and click on Settings, then select U3 Launchpad Settings and click
on the Uninstall tab. Some devices have a link to the Uninstall utility under Help and
Support.”

The [LOGFILE] command requires that at least 10% of the drive is free before it begins
logging. It will also automatically stop logging when free space drops below 1 MByte.

To view the directory structure and logged files, the USB drive must be dismounted and
moved to a PC.
To connect as Host directly to a USB flash drive, requires:
 Supplied Positronic 9-Pin Male to DB9S Data Cable (P/N 94-310260-3006LF)
 Positronic 9-Pin Male to USB 2.0 Host Receptacle Data Cable (P/N 94-310271-3006LF).
This cable is not supplied with the SF-3050.

The USB Host Data Cable is available via a NavCom authorized representative, or by
contacting the
NavCom Sales Department .
