Appendix F - GPSG-1000 USB Memory Device Format
Compatibility
The GPSG-1000 uses USB Memory Devices as a utility to update software and to import
and export almanac, route, and other files. Some types of USB Memory Devices have
proven to be un-readable by the GPSG-1000 due to incompatible formatting.
The GPSG
- 1000 requires a USB Memory Device to be formatted as FAT32 or FAT16 only.
It is also recommended that users have a dedicated USB Memory Device for the
GPSG - 1000 so that the directory structure does not get corrupted. The directory file
structure is shown in Figure 1 below.
VIAVI Solutions recommends USB Memory Device P/N 67325, available for purchase
from the VIAVI Solutions Customer Help Desk at 800-835-2350 or email
avcomm.service@viavisolutsions.com .
