TWedge V2

Solution: TWedge provides the function WriteToDevice () for this purpose. WriteToDevice () accepts two parameters:

• The first one specifies the data which should be sent to the device.
• The second parameter specifies the timeout (in milliseconds) for this operation.

The following example sends two lines of text: The first line prompts the device for accepting the username, the second line sends the username. Each line is terminated by a newline character (\n line feed):

WriteToDevice ("user\n", 1000);
WriteToDevice ("sysadmin\n", 1000);

TWedge V3

Solution: For this purpose TWedge provides the Javascript member function WriteData (). This function exists in two variants with different parameters.:

• Integer WriteData (Array arrData, Integer nTimeout)
• Integer WriteData (String sData, Integer nTimeout, String sEncoding = "Latin1")

The following example sends data one time as binary array and one time as string. Inside of a string you can encode a line feed with the escape sequence \n:

var arrSend = [0x48, 0x65, 0x6c, 0x6c, 0x6f];
hConn.WriteData (arrSend, 200);

hConn.WriteData ("Hello\n", 1000);

The App inserts data according to so called "Simulation Rules" (see cog wheel ⇒ Scanner Keyboard Preferences ⇒ Keyboard Behavior). Simulation rules allow you to customize the simulation/keyboard behavior for a specific target application. The "Default" rule is applied if no specific rule is available.

The app scans a code, makes the sound, but doesn’t put any text in the textbox? Some target apps require a different method to accept simulated keystrokes. Scanner keyboard offers two methods for this purpose. To insert data into some apps (especially web-based apps or browsers), enabling the option “Key by Key” in the corresponding simulation rule might be required.

If there is a problem, please try the following steps:

1. Open the Scanner Keyboard preferences.
2. Scroll down to Keyboard behaviour.
3. Select the required simulation rule (e.g. Chrome) / or create a new simulation rule for your target app / or open the Default simulation rule at the end of the list.
4. Enable the feature Key by keyin the Key simulation section.
5. Save the rule and test whether the data is inserted as expected.

If it doesn’t help, the problem might be time-related. You could try adding a Wait command before data insertion with the following steps:

1. Open the corresponding simulation rule (see 1.-3. above).
2. In the section Key simulation tap on Prefix and suffix settings.
3. Place the cursor in front of the string and tap the button PLACEHOLDER.
4. Find and add the placeholder ${WAIT###}, use 900 instead of ###.
5. Confirm with OK, your key simulation string may look like this now:

${WAIT900}${INPUT}

6. Save the rule.

Sometimes you may want to create multiple forms and send each form to its own sheet in your spreadsheet.

This can be solved with a Macro in Excel or with Google Apps Script in Google Sheets.
By adding a Static Text field with a category identifier to your forms the Macro/Script can identify the category of the captured data and move it to the desired sheet automatically.

Scan-IT to Office APP:

1. Add two new forms or edit your existing forms and add a “Static Text” field to each form.
2. Set the values of the “Static Text” fields to your desired category names
   (in this example we used “Cat1” and “Cat2”).
3. Make sure the “Static Text” field is the first field in your forms.
4. You may also want to hide the “Static Text” fields.

Microsoft Excel:

1. Download the sample spreadsheet and open it in Excel.
2. Insert the Scan-IT to Office Add-In.
3. Select “Insert after last non-empty row” in the Add-In options and make sure “ScanData” is selected.
4. Open the “Categories” sheet and change the values under “Category” to match the values of the “Static Text” fields.
5. If you want to rename your Sheets you also need to change the values under “Sheet” accordingly.

6. Note: Do not rename the “ScanData” sheet and the “Categories” sheet otherwise the Macro will stop working.

Google Sheets:

1. Open our sample spreadsheet.
2. Choose File -> Make a copy to make an editable copy of the sample.
3. Open the script editor select Tools -> Script editor.
4. In the script editor add a new trigger to the sheet
   Edit -> Current project’s triggers -> + Add Trigger
   Change the “Select event time” to “on change” and save the changes.
5. Insert the Scan-IT to Office Add-On into the spreadsheet or connect to the “ScanData” sheet via Google Sheets (Drive) connection.
6. If you are using the Add-On select "Insert after last non-empty row” in the Add-On options and make sure “ScanData” is selected.
7. Open the “Categories” sheet and change the values under “Category” to match the values of the “Static Text” fields.
8. If you want to rename your Sheets you also need to change the values under “Sheet” accordingly.
   
9. Note: Do not rename the “ScanData” sheet and the “Categories” sheet otherwise the Google Script will stop working.

Problem: My USB Device (Virtual COM Port) loses connection when not used for a while.

Power management is a common cause of USB-connected device issues. To save power, Windows automatically shuts down the power to USB ports. This may cause problems with auxiliary devices and leads to a connection loss if you don't use the device for a while.

Workaround: Here are some measures, which you can try step by step until the problem disappears:

a) Prevent Windows from Turning Off USB Devices

1. Open Device Manager by typing device manager in the Start 🡒 Search panel.
2. In the Device Manager expand the Universal Serial Bus controllers branch, double-click the USB Root Hub device and choose the Power Management tab.
3. Turn off "Allow the computer to turn off this device to save power" by unchecking the box.
4. Click the OK button

b) Motherboard: If your BIOS has a setting 'Deep Sleep Control', then disable it.

c) Turn off the "hybrid sleep option" (if available):

• In Control Panel go to Power Options 🡒 Change plan settings 🡒 Change advanced power settings 🡒 Sleep 🡒 "Allow hybrid sleep" and turn it OFF.

d) Turn off "USB selective suspend" (if available):

• In Control Panel go to Power options -> Change plan settings 🡒 Change advanced power settings 🡒 USB settings 🡒 "Selective suspend" and disable it.
