Operating instructions

OPERATING MANUAL 2945A
46882-311D 3-85
If a memory card is inserted that has not been formatted to the required standard, the message
’Card Not Formatted’ is displayed on the MEMORY CARD FORMAT screen.
To apply formatting, press the [Format Card] key. The message ’Writing To Mem Card. Do Not
Remove.’ is displayed until the formatting is completed. When the card has been successfully
formatted, the memory size will be displayed and the card title will show ’IFR Card’
Titling cards
To change the card title press the [Enter Title] key. A title can then be applied to the card using
the same procedure as for titling store locations (see ’Other memory functions, titling store
locations) earlier. A card title can have up to 11 characters, including any spaces.
Accessing the memory cards
When a memory card is in place, accessing the user store memory will also give access to the card
memory.
The STORE/RECALL screen or the DISPLAY AND HOLD/STORE screen are displayed as
described above.
By pressing the [
] key the memory store address list heading changes to ’MEMORY CARD’
and a format description. The locations are numbered 10 to 19. Successive operations of this key
will increment the numbering by 10 until the list is numbered from 90 to 99. Further operation of
the key will have no effect. To return to the lower numbered locations use the [
] key to
increment down.
Each memory card has capacity for 90 store locations. Therefore, with a memory card in place,
the number of store locations accessible through the STORE/RECALL screen or the DISPLAY
AND HOLD/STORE screen is increased to 100; locations 00 to 09 in the normal internal
memory, with locations 10 to 99 on the memory card.
Data is stored on the memory cards in files, using a DOS style format. These files can use as
much empty card space as they require. Therefore, if large files are stored, such as SYSTEM
User Defined test programs, the number of store locations available on that card may be reduced.
All operations relating to internal user stores apply to memory card operation, but with the
additional facilities for storing the following:-.
Bitmaps of test screens.
Parameter settings for system tests.
Results of system tests.
User defined test programs written in MI-BASIC.
Write-protecting cards
The contents of memory cards can be protected from accidental overwriting or erasure by using
the differing methods of protection available on the Service Monitor and the memory cards.
Write protect card switch
Setting the write-protect switch, on the non-contact end of the memory card, offers a physical
method of protecting the card contents.
Protect store function
The use of the [Protect Store] key described under ’other memory functions’ earlier, can be used
to protect any selected store location on the card. The protection information is contained on the
card and will remain active if the memory card is loaded in other service monitors or equipment.
Lock stores function
A coded lock function, accessible by using the [HELP/SETUP] [Card Setup] key sequence,
allows a portion of the store locations to be protected behind a four figure code. The use of this
function is described below.
