Serial Rapid IO Probe Manager - Pattern Recognizers

The sRIO Control Symbol and Packet sub-dialog screens are designed such that the minimum numbers of fields are specified to form a valid packet. Fields displaying X’s will be masked out. All reserved fields will be masked into the pattern. Every field is validated as the user is entering the hex values. The user may enter any combination of X’s and hex digits into each field. Each field may be edited in binary form by right clicking the mouse key, at which point the contents of the field are displayed in binary format in a separate window. When the user applies the binary values (by clicking the Accept button), the binary value is converted to a hex representation and displayed in the pattern dialog. Field Hex digits that are partially masked will be displayed with a “$” character. The packet recognition setups are created via sub-dialogs that are displayed whenever the user selects a packet type (via the radio buttons for each link pattern) and clicks the Edit button.
The pattern is edited if the user clicks the Apply button on the packet-specific sub-dialogue form. If edited, the packet type string is displayed in a light blue color.

Once edited, the pattern may be cleared by clicking the Clear button. This will inactivate the recognizer. Pattern Recognizers are used to trigger the logic analyzer whenever a specific packet or ordered set pattern is encountered. Each Pattern recognizer outputs a PAT_REC flag to the logic analyzer that pulses high during the 1st state of each packet. Pattern recognizers may also be used as filters. The Pattern Recognizer examines the first 24 bytes of each packet. Recognizers are set up by the Probe Manager with a match pattern and a separate mask pattern, giving the user control over the comparison, bit by bit. The probe must be stopped before editing patterns.You must always restart the probe by pressing the green run button on the main window so the new values will be written to the probe hardware.

You can see both of the dialog screens by selecting the links below.
