▸ Serial number length (the number of
characters)
This field determines how many characters the serial
number can hold. For example, 4 characters provide for
the serial numbers 0001 to 9999 in base 10 (i.e. in
decimal form).
▸ Number base
This option defines the base of the serial number
characters. Base 10 and base 16 are available (i.e. the
decimal and hexadecimal forms).
▸ Code as ASCII
With this option activated, serial numbers are legible as
ASCII characters.
▸ Initial serial number
This field defines the initial value from which serial
numbers are to be computed.
▸ Next S/N
This field defines how the following serial number is to be
generated.
If The same is selected, the serial number does not
change. If One interval higher is selected, the following
number will be larger by the value of ▸ Serial number
interval
while if One interval lower is selected, it will
reduce by that value.
The Generated LSFR option generates the numbers in a
pseudo-random sequence. This means that the sequence
will always be the same if the same Initial serial
number and the same Serial numbers step is used.
The Manual option shows a field, in the serial numbers
window, where the serial number in the hexadecimal form
can be entered before programming. When this option is
selected, the serial number can be entered using the /sn
commandline parameter as well.
▸ Destination
This panel determines the memory location in which the
serial numbers are to be stored. Code/main memory,
data memory and ID positions are available as
options.
▸ Hexadecimal address of first word
This address defines where the first word of the serial
number is to start in the selected memory type.
▸ Fill with RETLW instruction
Individual words of the serial number can be filled with
RETLW instruction in Microchip microcontrollers. This
option is available only if the serial number is located in
the code/main memory.
▸ Characters per word
This panel determines how many serial number
characters form one word. Options of 1 to 4 characters
per word are available.
▸ Sequence
This panel sets how individual serial number characters
and words are to be ordered.
For example, if you have a base 10 serial number
consisting of four characters organized as 2 characters
per word and you are working let's say with 1234 as the
serial number, it will be saved in the following ways:
HiLohilo:1234
hiloHiLo:3412
LoHilohi:2143
lohiLoHi:4321

▸ Show checksum in status bar
After enabling of this setting the checksum of the code
memory will be shown on the status bar.
When MD5 checksum algorithm is selected, the checksum
is shown after placing the mouse on MD5 text in the
status bar.
Note: Doubleclick on the checksum value in the status bar
will cause the value recalculation.
▸ Write checksum to log file
Enables writing of the loaded data file checksum to a log
file.
Note: The checksum is recalculated on data file load. This
function have to be enabled before the file load, else the
checksum value will not be written to the log file.
▸ Checksum algorithm
Using this choice the checksum calculation algorithm can
be chosen.

▸ Update check settings
Here you can set if the program should ask for your
permission to connect to the Internet and check for
updates upon each start or not.
For further information see
Updating UP.
▸ Allow internal and external supply
voltages collision
Warning
A collision of power supply voltages can
damage the programmer or the application!
If you approve the collision of supply voltages, it allows
the programmer to connect its internal voltage to pin
VDD at times when it can already see a voltage present
there. This could damage both the programmer and/or
the application being programmed.
This option has been included for very specific cases. One
of them can be a request to program an application,
which does not have any VDD pin. Then the application
must be powered from its own source but the
programmer's output buffers must be powered from the
USB. Yet as the voltage at the application's data signals
“sneaks” through the protective diodes into the output
section of the programmer, the programmer can see a
certain small voltage present at VDD and refuses to
connect its own internal voltage to it.
▸ Do not show warning if internal 5V is
switched on with 3.3V device
Warning
High a voltage at the device can damage the
programmer or the application being
programmed.
This option can be used to suppress the warning if a
higher voltage is switched on at the VDD output than the
value allowed for the particular device.
If there is a voltage convertor integrated in the
application between the device being programmed and
the programming interface, it might be useful to use this
option of programing at a higher voltage than what the
device has been designed for.
This option is available only for PRESTO.
▸ Allow to change supply voltage level
when it is on
In order to protect the application connected to FORTE
from damage, it is typically forbidden to change the
output voltage level if the voltage is currently connected
to the application. After activating this option, the output
voltage can be changed at any time within the range that
Page 57
the device being programmed can cope with.
▸ Allow external supply voltage for
devices requiring VPP before VCC.
For some devices their manufacturer requires the
programming voltage to be connected before the supply
voltage of the device. When the external supply voltage is
used, it does not comply with the specification. In this
case a warning is displayed, which can be permanently
disabled using this setting.
Disabling of this warning should be well considered. This
warning is displayed for devices for which the external
supply voltage violates the device manufacturer
specification.
▸ When using Windows Messages
disable other warnings
When controlled via Windows Messages the UP software
does not show any warnings, similarly like in quiet mode
on the commandline.
▸ Pin T during programming
With this setting it is possible to set a logical level during
programming on the T pin. The selected logical level will
be visible on the pin only when the supply voltage is
available at the VDD pin of the programmer.
In case that the T pin is used for programming, this
function will not be available.
This option is available only for FORTE.
▸ Pin T after programming
With this setting it is possible to set a logical level, which
will appear on the T pin after programming. The selected
logical level will be visible on the pin only when the
supply voltage is available at the VDD pin of the
programmer.
In case that the T pin is used for programming, this
function will not be available.
This option is available only for FORTE.
