How to turn on and off
Refer to the figure in section 1.1 to locate the SCAN and DOWN button.

• a) Press and hold the SCAN + DOWN buttons simultaneously for 3 seconds. b) The KDC will beep when it is turned ON.
• c) Press and hold the SCAN + DOWN buttons simultaneously for 3 seconds again to turn off the KDC.

Pairing (Bluetooth or NFC)

Connecting your KDC using Bluetooth is made easy with the below pairing barcodes.
If using an Android device, pairing via NFC is even easier: just approaching the KDC to the back of the host device’s NFC area is enough for pairing. For more details, see section 2.3

Bluetooth Profiles Explained

• a. HID Profile: Allows one-way Bluetooth communication with an Android or iOS host device. The KDC only transmits data to the host device.
• b. SPP Profile: Allows two-way Bluetooth communication. The KDC transmits data to the host device and the host device can transmit data back to the KDC.
• c. HID Windows Profile: Allows one-way Bluetooth communication with a Windows PC. The KDC only transmits data to the Windows PC.

Note: HID inputs data directly into an application. SPP requires the KOAMTAC KTSync ® app or integration of KOAMTAC SDK to input data into an application. To gain access to the SDK, please complete the form here: https://www.koamtac.com/sdk/

Bluetooth Pairing a KDC280 to your smart device with special barcodes

• a. Navigate to the Bluetooth setting on the host device and ensure that Bluetooth is both enabled and searching for devices.
• b. Using the KDC, scan the pairing barcode above that corresponds to your desired Bluetooth profile. If you are unsure which Bluetooth profile is right for you, please refer to Chapter section 2.1.
  • If you use an Android, iOS, or Mac device and desire an HID connection, then scan barcode #1 above.
  • If you use a Windows device and desire an HID connection, then scan barcode #2 above.
  • If you desire an SPP connection for any device, then scan barcode #3 above.
• c. In HID or HID Windows Profile, check the list of available Bluetooth devices on your host device. From the list, select the KDC280 listed by serial number in brackets that matches the serial number found on the back side of the KDC280. KDC280 will beep upon connection and display “BLE HID Connected” on its screen. Now it is ready to use.
• d. In SPP Profile for non-iOS, check the list of available Bluetooth devices on your host device. From the list, select the KDC280 listed by serial number in brackets that matches the serial number found on the back side of the KDC280. KDC280 will beep upon connection and display “BLE SPP Connected” on its screen, but you should launch KTSync or your application and select KDC280 within the application to complete the connection. Now it is ready to use.
• e. In SPP Profile for iOS, the KDC is NOT listed on your host device, so you should launch KTSync or your application and select the KDC280 listed by serial number in brackets that matches the serial number found on the back side of t he KDC280. KDC280 will beep upon connection and display “BLE SPP Connected” on its screen. Now it is ready to use.

Bluetooth Pairing a KDC280 to your smart device with NFC (Android Only)
This feature applies only to Android. KDC may be paired in either HID or SPP only.

• a. Navigate to the NFC setting on the host device and ensure that NFC is enabled.
• b. On the KDC, make sure NFC pairing is enabled by navigating to KDC MENU → BLE Config → NFC Pairing → Enabled → Save & Exit.
• c. On the KDC, select the pairing profile by navigating to KDC MENU → BT Config → Connect Device → Select HID or SPP → Save & Exit.

Or, select the profile using the special barcodes below:

• a. Approach the NFC area on the back of the host device with the KDC to complete pairing.

Usage

Using Keyboard Wedge (HID Keyboard)
This option is only available using Bluetooth connection with HID profile.
Once the KDC is paired with the host, open any application with a text field and tap on the text field. Scan any barcode and it will populate in the text field.

Using KTSync – Android/iOS
You can use KTSync to utilize your KDC alone or with a native application. This is only available using a Bluetooth connection with SPP.

• a) Download and install KTSync from the Google Play Store or the Apple App Store.
• b) Open KTSync and tap on the “Connect” option on the bottom left to view a list of available devices. (Fig. 1)
• c) In case of Android, the pairing should be established from Settings of the phone and in case of iOS, “START BLE SCANNING” menu should be run from “Connect” menu.
• d) From the device list, select your KDC – ensuring that the serial number displayed in brackets matches the serial number on the back of your KDC. (Fig. 2)
• e) Upon successful connection, KTSync will display “Connected” next to the name of your KDC at the top of the application. (Fig. 3)
• f) To test your connection, scan any barcode. If the connection is successful, the barcode data will display on the screen. (Fig. 3)

In Always-pairing mode, an application can connect to a KDC without reading a pairing barcode, so the connection procedure is a little different.

• a) In the KTSync app, tap the Connect icon at the bottom left of the app.
• b) In KTSync, tap “START BLE SCANNING” in the top right.
• c) In KTSync, check the list of found devices.
• d) In KTSync, tap the KDC280 listed by serial number in brackets followed by [BLE] that matches the serial number found on the back side of the KDC280. The format will look like this, KDC280[xxxxxx] [BLE], where xxxxxx is the serial number.
• e) The KDC280 will beep upon connection and display “BLE SPP Connected” on its screen. Now it is ready to use.

Using KTSync Keyboard – Android
Once your KDC is connected to KTSync, you can use your KDC as a keyboard.

• a) While KTSync is running in the background, navigate to Settings > Language & Input > Virtual Keyboard > Manage keyboards
• b) Tap on “KTSync Keyboard” to enable it.
• c) Change “KTSync Keyboard” to the default keyboard. (Fig. 5)

To switch back to the previous keyboard, simply change the default keyboard again. Or, when a text field is selected swipe down from the top of the screen to bring up the notification panel. Select ‘choose input method’ and you can select the default keyboard from here. (Fig. 6)

Using KTSync Keyboard – iOS
Once your KDC is connected to KTSync, you can use your KDC as a keyboard.

• a) Navigate to the iPhone/iPad/iPod Settings > General > Keyboard > Keyboards > Add New Keyboard…
  • Select the KTSync keyboard to be added. (Fig. 7)
• b) Select the KTSync Keyboard and toggle the switch to Allow Full Access. (Fig. 8)
• c) Open the application you want to scan into and tap on the screen, so the on-screen keyboard appears.
• d) Press and hold the globe icon located to the left of the spacebar.
• e) Select the KTSync Keyboard and begin scanning. (Fig. 9)

Social Distancing Feature

The COVID-19 pandemic has added a new challenge to every workplace – warehouses, manufacturing lines, and even retail store floors – the need to maintain distance between people for their health and safety. Reopening your business is already an undertaking but ensuring social distance among your workers is made easy with the KOAMTAC social distancing feature.
Whether you’re a small or enterprise business, the KOAMTAC social distancing feature works with the technology and systems you already have in place so you, and your workers, can have peace-of-mind as you adjust to the new normal.

• Supported on all Bluetooth Low Energy (BLE) 5.0 KDC devices.
• For more on the social distancing feature, please watch: https://youtu.be/m4Manx9vK68

There are three ways to enable and control the settings for the social distancing feature:

1. Enable via the KDC menu
2. Scan the special Social Distance barcodes that correspond with the settings you wish to enable
3. Enable via the KTSync application

Social Distancing Feature Parameters
The following parameters can be changed:

• Distance: Set the acceptable social distance range with values between 1 to 10 meters (Default: Disabled).
• Host Alert: This setting will forward distance alerts to the connected host device (Default: Disabled).
• KDC Alert: This setting allows the user to enable/disable an audible beep sound (Default: Enabled), vibration (Default: Disabled), and data storage (Default: Disabled) settings for distance violations on the KDC.
• Security Key: Choose keys between devices. Only KDC devices using the same key will be able to detect and report the distance between devices. If the security key is “Disabled”, the KDC won’t use any key. If “Fixed Key” is selected, the KDC will use a predefined key. If you prefer to set your own custom key by selecting “Custom Key”, the custom key can only be set through KTSync (Default: Fixed Key).

Enabling the Social Distancing Feature via the KDC Menu
If you prefer to enable the social distancing feature by navigating through the KDC menu, then follow the instructions below:

• a) From KDC BLE Config menu, select Social Dist. to configure
• b) Set the Distance from 1m to 10m
• c) Set the Host Alert to enable/disable
• d) Set the KDC Alert: Beep, Vibrator, and Data Store to desired settings
• e) Set the Security Key: Disabled, Fixed Key, or Custom Key

Enabling the Social Distancing Feature via Social Distance Barcodes
If you prefer to enable the social distancing feature via special barcodes, scan the special social distance barcodes that correspond with the settings you wish to enable:

Enabling the Social Distancing Feature via the KTSync application
The social distancing feature can also be configured in the KTSync application.

• a) Open KTSync and tap the Setting icon
• b) Select KDC Menu (Fig. 10)
• c) Select Social Distance Finding (Fig. 11)
• d) Choose your Social Distance settings. Settings listed in the KDC Configuration section are the same settings available to you as if you were setting parameters on the KDC itself. These settings will be saved when you exit this screen. (Fig. 12)
• e) Additional Application Configuration settings can be set on this screen as well. (Fig. 12)
  • Enable Vibrator: If enabled, the host device vibrates when receiving social distance alert data.
  • Enable Email Sending: If enabled, email application is launched instead of a social distance data pop up when receiving social distance alert data.
  • Email Address: Register and email address to send social alert events.

Examples of Social Distance Alerts & Social Distance Alert Data
Whenever the KDC is connected, the KDC is sending social distance alert data to host device if host alert is enabled and another KDC is found within the selected distance range. When a social distance violation occurs, you may receive these alerts, depending on settings:

1. Social distance warning on KDC, showing your KDC serial number accompanied by beep/vibrate if selected. (Fig. 13)
2. Social distance pop-up in KTSync showing your KDC serial number, the date & time of the violation, the serial number of the other detected KDC, and the distance if using the host alert setting. (Fig. 14)
3. Social distance email showing your KDC serial number, the date & time of the violation, the serial number of the other detected KDC, and the distance if using the enable email sending setting. (Fig. 15)

* Note:* When reconnected, the KDC will send social distance data to the host device even if the same KDC is found within distance.
Note:** Only one social distance data alert is sent to the host device when multiple KDC devices are detected if social alert is already being displayed as a pop-up or email application is already launched.
