device program operation and loaded in selected format to specified buffer address prior to
programming of each device.
There are following options, that user can modify for incremental mode:
S / N size
S / N size option defines the number of bytes of serial value which will be written to buffer.
For Bin (binary) serialization modes values 1-8 are valid for S / N size and for ASCII
serialization modes values 1-16 are valid for S / N size.
Address
Address option specifies the buffer address, where serial value has to be written. Note that
address range must be inside the device start and device end addresses. Address must be
correctly specified so the last (highest or lowest) byte of serial value must be inside device
start and device end address range.
Start value
Start value option specifies the initial value, from which serialization will start. Generally, the
max. value for serialization is $1FFFFFFF in 32 bit long word.
When the actual serial value exceeds maximum value, three most significant bits of serial
number are set to zero. After this action the number is always inside 0..$1FFFFFFF interval
(this is basic style of overflow handling).
Step
Step options specify the increment step of serial value incrementation.
S / N mode
S / N mode option defines the form in which serial value has to be written to buffer. Two
options are available:
• ASCII
• Bin
ASCII - means the serial number is written to buffer as ASCII string. For example number
$0528CD is in ASCII mode written to buffer as 30h 35h 32h 38h 43h 44h ('0' '5' '2' '8' 'C' 'D'),
i.e. six bytes.
Bin - means the serial number is written directly to buffer. If the serial number has more than
one byte length, it can be written in one of two possible byte orders. The byte order can be
changed in „Save to buffer" item.
Style
Style option defines serial number base. There are two options:
• Decimal
• Hexadecimal.
Decimal numbers are entered and displayed using the characters '0' through '9'.
Hexadecimal numbers also use characters 'A' through 'F'.
The special case is Binary Dec, which means BCD number style. BCD means the decimal
number is stored in hexadecimal number, i.e. each nibble must have value from 0 to 9.
Values A to F are not allowed as nibbles of BCD numbers.
Select the base in „Style" options before entering numbers of serial start value and step.
