RELOADING EMBEDDED SOFTWARE INTO PG7000
FLASH MEMORY
PG7000 models use FLASH memory. This allows the embedded software that controls PG7000
operations and functions to be loaded into PG7000 over its COM2 port from a personal computer with a
simple FLASH loading utility.
To replace corrupted software or upgrade to a new version, your
DHI
Authorized Service Provider can
provide you with a FLASH memory loading utility along with a file containing the PG7000
embedded software. For greatest convenience, these are available from
DHI
’s worldwide web site:
www.dhinstruments.com
.
If the embedded software you are using is suspected of having a problem, record all symptoms and
contact your
DHI
Authorized Service Provider.
A NULL MODEM cable must be used to flash embedded software into the PG7000. A NULL MODEM
cable is supplied with the PG7000 accessories. It is a well known cable configuration available from most cable
and computer product suppliers. A “straight-through” cable such as that used for standard RS232
communications will NOT communicate to allow flash memory writing.
The DHI flash software loading utility and PG7000 embedded software are available for download from
the SOFTWARE section of DHI’s
worldwide web site at www.dhinstruments.com.
