725X Service Manual
Chapter 1: 725X Service Characteristics
The aim of this introductory chapter is to illustrate some of the characteristics of the
725X of fundamental importance to the technical staff, in particular, where to find the
equipment status and how to keep it up to date.
Identifying the boards
Each board of the 725X is identified:
• by its Code (950..), which is always indicated on the printed circuit, and its
description, which is indicated on a label affixed to the handle or the printed
circuit
• by the Serial Number, indicated on a label affixed to the handle or the printed
circuit
• by the Configuration Index (CI), also on a label affixed to the handle or the
printed circuit
• by its Firmware (FW) level (when applicable), displayed in the System
Configuration screen, Firmware Option (see next paragraphs)
The Configuration Index represents the HW level of the board and is indicated by
two decimal figures: the label will therefore be marked CONF.NN.
Board Configuration Index and Firmware Level
When the CPU is switched on, it reads these values: the results of this reading is, in
fact, displayed in the Configuration screen, Boards and Firmware options (see next
paragraph).
The Firmware is memorised on Flash EPROMs and it is updated via Floppy disk.
The Configuration index is memorised on the board on different supports. Some
boards have this value memorised on the EPROMs or on a PAL, the next table
details which boards use these supports.

The up-dating of the configuration index will therefore be operationally different. If the
support is a Flash EPROM or an EEPROM, the index will be updated via Floppy
disk. Moreover the CI has to be set via a specific Service menu (see Chapter
“Configuration and Calibration procedures”)
In all the other cases the support will be replaced during updating: except for the
Power Supply, all the supports are on a base.
As already mentioned, the Configuration Index is also given on a label (CONF:NN)
attached to the board. Whichever way this index is managed you are advised to
update this label every time a modification is made on the field.
Configuration Screen
From the keyboard you can display the Configuration Screen. To do this, press
<MENU> key and select <SYSTEM INFO> option. The unit will shows:

The most important information displayed is:
• the Serial Number of the device
• the release resident in the CPU
• the SW release installed and the licenced ones

• the Output Data System release (they are the acoustic output data stored in
UP4, CPU board)
• the installed optional modules
With the trackball, you can enter the BOARDS option and it will be displayed

The BOARDS option has two lists:
♦ the Board column lists all the installable boards. If a board is not installed (for
example a board belonging to an optional module), it is anyway displayed
♦ the CI column lists the Configuration Index (the [NN] figures) of the installed
boards. When a board is not installed, the unit displays [--].

The Firmware option shows the installed boards equipped with Flash EPROM (Board
column), the Flash assembly code (UPN) and the Firmware version (when installed)
with the relevant date. Remind that the ODS data, stored in the CPU and displayed
in the General option, has to be considered Firmware: therefore the ODS update
follows the same criteria of any other FW upgrade.
On shipment from Esaote, the charts of the initial configuration are placed in a
pocket on the lower cabinet of the device. The technical staff will be responsible for
keeping these charts up to date with the actual configuration of the device.
Machine Self-test
At power-on, the CPU executes a self-test to check:
• which boards are installed on the device
• their Configuration Index and their FW
• which SW release is installed
I-5
725X Service Manual
The result of this self-test is displayed for a short time, before the ID Menu. However
you can access to the Configuration Screen in Real Time or in Freeze by pressing
the Menu key and selecting the System Info option.
The initial self-test has a dual function:
• “self-configuration”
If new features have been added (e.g. the Doppler Module has been installed), the
CPU automatically reconfigures itself to manage the new devices. The Configuration
display indicates the changes made: with reference to the same example, the screen
will show the DOPPLER MODULE field as ON and consequently the levels of the
configuration indexes of the new boards installed can be read.
N.B. For the Front End upgrades see the chapter “Upgrading the 725X”
• control
The CPU checks for internal conflicts and, if there are any, displays a warning
message.
Configuration Conflicts
If there are conflicts between HW levels of boards or between HW and SW, the
system stops at the General Configuration screen and displays the following
message:
System Configuration Error: Board(s) not present or not compatible
In the BOARDS option, all the fields that caused the conflict are displayed in red. For
example, if a board has a configuration index incompatible with the HW level of the
device, the Configuration Index field of that board will be red. This screen thus
represents a useful diagnostic tool for technical staff. This screen may be bypassed
by pressing the <ESC> key and access gained to the ID Menu.
Updating the device
The 725X is designed so as to minimize the number of updating procedures that
require operations to be carried out directly on the system. This is possible due to the
use of Flash EPROM which may be updated by means of a Floppy Disk. Each
device has a Floppy Disk drive installed on the left-hand side: the Flash EPROM is
updated directly without having to remove the machine's casing.
The SW used on the machine is present in Flash EPROM installed physically on the
CPU board: the procedure for updating the SW release does not require any boards
or cassettes to be changed. As we have seen, the release installed appears on the
Configuration display.
I-6
725X Service Manual
The same philosophy is used for storing all the probe control tables: all the boards
involved in controlling the probes (in particular, the Scan Converter, RF I, Delay
Control and Scan Control boards) have one or more Flash EPROM modules
installed. Whenever the number of probes managed by the 725X is changed, the
new tables must be loaded from a Floppy disk.
The release installed in the Flash Eprom is controlled using the Firmware option of
the Configuration screen.
If there are conflicts caused by the firmware releases installed, the characters of
these fields will be displayed in red.
