Summary

• Title text - title is used when printing and displayed during polling
• Polling Screen button - use this definition and go to the polling screen
• Back to Main Menu button - will close com (if necessary) and return to main menu (same as ctrl-q)
• Code hexadecimal - hexadecimal command sent to OBD2 describing data point requested
• Code Description text - Description of code, used as a label and displayed during polling
• Unit Conversion choice list - describes any unit conversions to be performed on the data when displaying
• Poll Frequency numeric - the modula of the loop index to schedule the event in the polling loops. The lower the number, the more often polled. In example, 1 - event polled every loop, 2 polled every other loop, 3 every 3rd loop,etc. The exact timing varies with vehicle. In most tested cases, events occur about 300ms apart, a little over 3 events per second. Some vehicles respond at 10 events per second (100ms apart), while a few notable exceptions respond upto 40 events per second (25ms apart)
• Offset numeric - Added to poll index before calculating modula. Used to formalize grouping of events when polling occurs. In example, if 3 events have a poll frequency of 2, the offsets 0 and 1 may be used to group any of the events into the first loop or the second loop. Offsets greater than the poll frequency are simply treated as equal to (offset modula poll-frequency). In this way, precise control of polling events can be achieved. To view the current polling events by loop, use the menu item Show Poll Timeline under the Tools menu.
• Status Description text - displays any messages, and the number of bytes transferred while using this screen.
