- Invert results bit, can be used for bit inversion in the final CRC
- Polynom Dec, an informative field
- Options
On the right of the Checksum settings window, under Test Checksum/
CRC, you can test how the parameters listed under Checksum/CRT
work on a test string for which you know the CRT Dec and Hex values
and the CRT Hex string. This way, you will be able to find the correct
checksum parameters for the report you are creating.
Binary Report
You can also create binary reports, that is, reports where data is stored
as binary instead of visible ASCII characters. It is also possible to pack
data so that one data item uses only a limited number of bits.
Creating Binary Report
To configure a binary report, proceed as follows:
1. In the Reports view, select Binary report from the Available
templates list and click New to create a new report; see
Figure 108
on page 208 .
A binary report is configured like any other report.
Parameter Option Description
Bit reverse CRC used CRC is displayed in a reversed order, the
lowest bit is exchanged with the highest bit
and so on
User polynom bits
reversed Only available with USER CRC. The lowest
bit is exchanged with the highest bit and so
on.
