QQ99..66::
Why doesn't the store / recall facility work when I try to
store /recall TETRA settings?
AA99..66::
The IFR 2968 store/recall facility incorporates both internal
stores and external stores; external stores use a memory card.
The internal stores (numbered 00 to 19) only store the settings
relating to the 'NO SYSTEM' analogue functionality of the 2968.
The external stores (numbered 20 to 99) use a memory card, and
can store SYSTEMS set-up information, user defined autotest pro-
grams, autotest results and screen dump images. Refer to the IFR
2968 Phase 3.2 TETRA supplement issue 10, chapter 10, for
details.
QQ99..77::
Can I use a FLASH memory card instead of a battery
backed SRAM memory card?
AA99..77::
Yes and no. The IFR 2968 is unable to write to (program)
FLASH memory cards, but it can read them. Therefore you need
an SRAM card to save 2968 information to stores. Once you have
done this, you can copy the SRAM card information to a FLASH
card using a PC, and you can recall the stored information from
the FLASH card to the 2968. You will not be able to rename or
delete or alter the stored information in the FLASH card from the
2968 as it cannot write to the card. This could be useful if you
wish to create a 'master' set of stored 2968 settings to be copied
to a number of other 2968s. Create the master settings on an
SRAM card and use a PC to make multiple read-only copies onto
FLASH cards.
QQ99..88::
Can I capture a 2968 screen image and use it in PC appli-
cations?
AA99..88::
Yes, this is how we create the screen shots that you see in
the IFR 2968 operating manual and TETRA supplement. Screen
dumps are created by pressing the [COPY] hardkey, which gives
you the option of copying the image to a printer, storing the image
on a memory card, or simply holding the display. To capture the
image on a PC you need to connect the PC serial port to the IFR
2968 serial port using a null modem cable, and you need to set
the IFR 2968 to print using the serial port.
The data sent to the PC serial port will be printer control informa-
tion. IFR can supply free of charge on request a DOS utility
"2965scrn.exe" that captures the screen image from the printer
control information and creates a bit image that can be saved as
a .bmp file for inclusion in Windows applications. N.B. this utility is
unsupported and unwarranted but it is tried and tested and has
been used for many years.
To set up the IFR 2968 to print to a PC running the IFR screen cap-
ture utility, press the [HELP/SET-UP] hardkey, then the softkeys
[SET-UP], [INPUT OUTPUT], [ serial set-up ], then set the following
parameters:
baud rate: 9600
parity: none
data bits: 8
stop bits: 1
duplex echo: off
press [return] and [printer options] softkeys and set the following
parameters:
printer port: serial
printer driver: HP LaserJet (III/IV)/DeskJet 150 dpi
time & date: no time and date on screen dump
press [return] [return] [return] [return] or [HELP/SET-UP] [return]
Now run 2965scrn.exe on the PC. Press [COPY] [COPY] and the
2968 screen image should gradually appear on the PC screen.
When the image capture is complete, use the PC 'File' 'Save .BMP
File' options to save the captured image to a named file on the
PC. Note that when you next press [COPY] [COPY] the current
captured image is over-written by the new one, so make sure you
save each image to a separate file if you wish to keep it.
