# Scan Data Window

When you are working with a device that is connected to your PC, the Scan Data Window button is enabled. The Scan Data Window is used to send serial commands to a device, or to create programming bar codes.

## Command Center

The Command Center tab is used when you wish to send a serial command to a connected device. Type in the serial command and click the Send Command button:

Note: If you are working with a disconnected device, the Command Center tab will not be active.

When working with a connected device, the bottom of the Scan Data Window displays several check boxes that allow you to customize the types and the format of responses in the Scan Data Window.

#### Show Request/Response Tags

When queries are sent to the device and responses are returned, this selection displays the prefixes "Request" and "Response." For example, when Show Request/Response Tags is checked, the query BEPLVL? returns the following:

Request: BEPLVL?

Response: BEPLVL2[ACK].

When Show Request/Response Tags is unchecked, the query BEPLVL? returns the same messages, but without the prefixes:

BEPLVL?

BEPLVL2[ACK].

#### Expand Control Characters

This selection displays control characters. For example, when Expand Control Characters is checked, the query BEPLVL? returns the following:

Request: BEPLVL?

Response: BEPLVL2[ACK].

When Expand Control Characters is unchecked, the query BEPLVL? returns the following:

Request: BEPLVL?

Response: BEPLVL2-.

#### Hex

This selection displays queries and responses in the hex equivalent. For example, when Hex is checked, the query BEPLVL? returns the following:

Request: 42 45 50 4c 56 4c 3f

Response: 42 45 50 4c 56 4c 32 06 2e

#### HID Keyboard Single Data Display

This selection applies only to HID Keyboard interfaces. When it is unchecked, the HID keyboard data displays twice. When it is checked, the HID keyboard data displays just once.

## Create Programming Bar Code

The Create Programming Bar Code tab is used to create a 1D or 2D bar code either from a typed serial command, or from the parameters you requested using the Generate Bar Code button.

Enter a serial command and adjust the size of the bar code(s) vertically or horizontally using the slide bars. You can also click on the Symbologies drop down to select the symbology type for the bar code. Click on the Create 1D Bar Code or Create 2D Bar Code button. Your generated bar code appears. You may add a title or comments to this bar code before printing it.

Note: If you are using a 1D scanner, you will only be able to create a 1D bar code.
