The aim of this introductory chapter is to illustrate some of the characteristics of the 7200 offundamental importance to the technical staff, in particular, where to find the equipment statusand how to keep it up to date.

Each board of the 7200 is identified:

by its code (950..or 9100), which is always indicated on the printed circuit, and itsdescription, 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, also on a label affixed to the handle or the printed circuit

The Configuration Index represents the HW level of the board and is indicated by two decimalfigures: the label will therefore be marked CONF.NN. The figures represent the numerictranscoding of a series of resistors welded on the printed circuit of the board: differentconfiguration indexes correspond to different resistor layouts. The CPU reads the layout ofthese resistors to find out the Configuration Index of the single boards.

You can find out which boards are installed and their HW level without having to remove themachines casing: from the keyboard you can display the Configuration Screen (Fig.1). To dothis, press key and select option.

The most important information displayed is:

the Serial Number of the device

the release resident in the CPU

the SW release installed

the Licences installed

a list of the boards installed and their Configuration Indexes

In particular, beside the name of each board there are two numbers in square brackets [NN]:these numbers form the Configuration Index of the corresponding board.

On shipment from Esaote, a chart of the initial configuration is placed in a pocket on thelower cabinet of the device. The technical staff will be responsible for keeping this chart up todate with the actual configuration of the device.

All the fields that caused the conflict are displayed in red. For example, if a board has aconfiguration index incompatible with the HW level of the device, the Configuration Indexfield of that board will be red (maybe simply because the configuration resistors have not beenadapted to the new configuration). This screen thus represents a useful diagnostic tool fortechnical staff. This screen may be bypassed by pressing the key and access gained tothe ID Menu.

The 7200 is designed so as to minimize the number of updating procedures that requireoperations to be carried out directly on the system. This is possible due to the use of FlashEPROM which may be updated by means of a Floppy Disk. Each device has a Floppy Diskdrive installed on the left-hand side: the Flash EPROM is updated directly without having toremove the machines casing.

The SW used on the machine is present in Flash EPROM installed physically on the CPUboard: the procedure for updating the SW release does not require any boards or cassettes tobe changed. As we have seen, the release installed appears on the Configuration display.

The same philosophy is used for storing all the probe control tables: all the boards involved incontrolling the probes (in particular, the Master, Motor and Scan boards) have one or moreFlash EPROM modules installed. Whenever the number of probes managed by the 7200 ischanged, the new tables must be loaded from a Floppy disk.

The release installed in the Flash Eprom is controlled using the same screen (Fig.1). As can beseen, beside the lines of the Scan, Master and Motor boards, in addition to the ConfigurationIndex [NN], there is a series of characters in the following format:

UPNN NX 720NNNNX

where N is a numeric character and X is a letter corresponding to the firmware release.

The first field represents the assembly code of the Flash EPROM, the second represents therelease installed while the last series of characters is the code of the Floppy diskcorresponding to the release installed, the firmware code installed

If there are conflicts caused by the firmware releases installed, the characters of these fieldswill be displayed in red.
