Calculating CRCs or FCSs

The cyclic redundancy check (CRC) is a function on the Event Display window used to produce a checksum. The frame check sequence (FCS) are the extra checksum characters added to a frame to detect errors.

  1. Open the Event Display window.
  2. Click and drag to select the data for which you want to generate a CRC.
  3. Event Display CRCClick on the CRC icon .
  4. In the CRC dialog box, click on the down arrow to show the list of choices for CRC algorithms..
  5. Enter a Seed value in hexadecimal if desired.
  6. Click OK to generate the CRC.  It appears in the byte information lines at the bottom of the Event Display window.  Whenever you select a range of data, a CRC is calculated automatically.
