Field Service Guide
The external connections to the HFA II - i are considerably different from those of the HFA II.
Two USB and a network port have been added to the HFA II - i . These ports are inoperative at
this time. While the HFA II had three serial ports, the HFA II - i has only one functional serial
port.
Service Changes -
Calibration of the HFA II - i will differ from the HFA II only in the fact that the calibration data
will be stored differently. In the HFA II the calibration data is stored in the EEPROM, located
on the CPU PCB. In the
HFA II - i , the calibration data is stored in a file on the hard drive. An
additional copy of the calibration data is stored on a floppy diskette. The calibration diskette is
stored behind the rear cover door of the instrument. In cases where the calibration file on the
hard drive becomes damaged, the calibration data from the floppy can be loaded back onto
the hard drive via the main calibration menu.
The Diagnostic Service Tool (DST) has been changed significantly for use on the HFA II - i .
The DST will no longer perform the CPU PCB tests. These functions will be performed using
the Quick Tech-Pro Tool, its operation will be described in a future service bulletin.
The Quick Tech-Pro Tool is used with the HFA II - i to test the CPU PCB functions, IDE hard
drive, magnetic optical drive, printer, serial ports and parallel port. This utility is a self booting
application that will allow the use of three prepared diagnostic programs designed for the
HFA
II - i, or the choice of selecting any of the individual tests in the Quick Tech 2000 Pro test
library.
Unlike the HFA II, the HFA II - i has a BIOS that can be modified as needed with future
updates. See Appendix E for BIOS Configuration.
A significant difference between the HFA II and the
HFA II - i is that the HFA II operating
system would allow low level formatting of the floppy drives ( formatting a previously
unformatted diskette). This is not possible with the
HFA II - i . The HFA II - i will only allow
a preformatted diskette to be reformatted . The HFA II - i will not format
unformatted floppy diskettes.
The HFA II and the HFA II - i use the same floppy drives, but the jumper settings are different
for the two models. See Bulletin FA2i-003(x) for details on jumper information.
The HFA II - i will no longer support the laptop connection and CPU diagnostics. CPU
diagnostics will be performed with the Quick Tech-Pro Tool.
