Appendix C
A-102
NOTE 1:
If a prompt is displayed on the DDF4088 requesting a serial number, refer to
Section A.6.3.
NOTE 2:
If the software upgrade was performed from a DDF3088, the software
upgrade files should be deleted from the DDF3088 using the HCOM utility.
This allows more space for recording data log files. However, if sufficient
space exists for normal data log recording, PL.EXE may be left in place for
future usage of PolyLink.
A.6.2 INITIAL UPGRADES OF THE DDF4088 (NON-POLYLINK UPGRADE)
There are two separate procedures for upgrading the DDF4088, depending on the version
of software that is currently installed in the flowmeter, as follows:
!
Procedure for initial upgrades (that is, upgrades from version 1.0 to any other version)
!
Procedure for all subsequent upgrades (that is, all upgrades from version 1.1 or higher
to any other version)
Initial upgrades of a DDF4088 do not use the PolyLink utility, but the initial upgrade
procedure is provided in this section for reference. Once the initial upgrade is performed,
all subsequent upgrades are handled through PolyLink (Section A.6.1).
To perform an initial upgrade of the DDF4088:
1. Turn off power to the DDF4088.
2. Open the door on the DDF4088 and remove the sheetmetal access cover (attached by
two screws).
3. Connect a null modem cable to the DB9 connector on the main board of the DDF4088
(not to the DB25 connector as is done with PolyLink).
4. Connect the other end of the null modem cable to the PC.
NOTE:
If using a DDF3088, skip steps 3 and 4. Connect the round end of the RS232
Com Cable to the RS232 port of the DDF3088 (Figure A-2). Connect the
other end of the cable to the DB9 connector of the DDF4088.
