Table Display



Table Display

The Table Display is the main control window for scan tool diagnostic parameters. What you chose to list in the table display window is what the program will poll the vehicle for. Any gauges, charts or histograms opened will require the parameter to be listed in the table display for functionality.

A parameter is also known as a PID. When you insert parameters into the table display and other forums, VCM Scanner and its help files will refer to them as PIDs.

For information on configuring the Enhanced IO portion of the Table Display (the bottom 3 rows) please read Configuring the Enhanced IO.

Right click the table display for more options.

Bytes Used and Total Bytes Allowed

Each vehicle platform has a specific number of data bytes allocated for diagnostic scanning. What this means is that you can only ask for a limited amount of PIDs depending on the vehicle you are connected to. Some vehicles support 24 bytes, some support 48, and others support 56.

Also, not all PIDs are only 1 byte in length. Some PID's are 2 bytes, and others are 4 bytes in length.

The table display window status bar will tell you how many bytes you have allocated and how many you are allowed to allocate.


Logging Speed

Logging speed is dependant on the number of bytes you are logging, and the total number of bytes allowed.
The charts below list the average frames per second you will see based on the number of bytes you are scanning (on the left) versus the number of bytes allowed (on the top).

  24 Byte Max 48 Byte Max
1-6 Bytes 20 frames/sec 40 frames/sec
7-12 Bytes 10 frames/sec 20 frames/sec
13-24 Bytes 5 frames/sec 10 frames/sec
25-48 Bytes n/a 5 frames/sec

  56 Byte Max 56 Byte Max E38/E67 ECM
1-7 Bytes 40 frames/sec 40 frames/sec
8-14 Bytes 20 frames/sec 40 frames/sec
15-28 Bytes 10 frames/sec 40 frames/sec
29-56 Bytes 5 frames/sec 20 frames/sec


Inserting a PID

Right click the table display and select insert. You can also use the Insert and Delete keys.
To insert a vehicle parameter, click the top most table.
To insert an EIO input for an EIO interface, click the middle table.
To insert ah EIO output for an EIO interface, click the bottom most table.


Understanding the Insert List

In the list below, Manifold Absolute Pressure (SAE) and Knock Retard are already on our table display. The list indicates that they are added with a red color. The bottom of the Insert List notes the Source of the PID, how many bytes it will use and the generic sensor it can represent.
