1.2 How to turn on and off
Refer to the figure in section 1.1 to locate the SCAN and DOWN buttons.
Note: The trigger on the Ring Scanner and Finger Trigger Glove work as SCAN buttons.
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
2.1 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 Windows host
device. The KDC only transmits data to the host device.
Note:HID inputs data directly into an application. SPP requires the KOAMTAC SDK to
input data into an application. To gain access to the SDK, please complete the form here:
https://www.koamtac.com/sdk/

2.2 Bluetooth Pairing a KDC80 to your smart device with special barcodes
Bluetooth Profile & Pairing
#1. HID-BLE & Pairing (Android, iOS, Mac)
#2. HID-Windows & Pairing (Windows)
#3. SPP-BLE & Pairing (Android, iOS, Mac, Windows)
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 KDC80 listed by serial number in brackets that matches
the serial number found on the back side of the KDC80. KDC80 will beep upon
connection and display “Bluetooth 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 KDC80 listed by serial number in brackets that matches
the serial number found on the back side of the KDC80. KDC80 will beep upon
connection and display “Bluetooth Connected” on its screen, but you should launch
KTSync or your application and select KDC80 within the application to complete the
connection. Now it is ready to use.

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 KDC80 listed by serial number in brackets followed by [BLE] that matches the serial
number found on the back side of the KDC80. The format will look like this, KDC80[xxxxxx] [BLE], where
xxxxxx is the serial number.
e) The KDC80 will beep upon connection and display “Bluetooth Connected” on its screen. Now it is
ready to use.

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
KDC80 does not have a vibrate feature. So please ignore the vibrate for Social Distancing Feature.
5.1 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 between fixed key or a custom key. Only KDC devices using the same key will be
able to detect and report the distance between devices. If fixed key is selected, the KDC will use a
predefined key. If you prefer to set your own custom key, this action can only be performed though
using KTSync (Default: Fixed Key).

5.5 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.
