2.2 KDC470/475 Diagram
Before using the KDC, the user should become familiar with its physical characteristics. Refer to the figure
below. This figure indicates the placement of the SCAN/UP/DOWN buttons, LED, USB port, and others on the
KDC.
*KDC475 is identical with the exception of an angled scan window
2.3 How to Turn the Device On or Off
KDC470/475 has a power on/off switch. Please turn on the power first before using the device.
a) KDC470/475 is shipped with the power off.
b) To turn on, press any SCAN button and DOWN button together for 3 seconds at the same
time until you hear a short beep sound. KDC470/475 will sound a long beep when it is
ready to use. (You should hear the long beep in about 30 seconds.) (* 2017/2018/early
2019 versions of KDC470/475 turn on upon pressing scan button.)

2.5 How to Connect PC with KDC or Phone
This functionality only applies to KDC470/475 integrated charging case (SmartSled Custom Case).
The KDC470/475 automatically sets up a communication path with PC when you plug in USB cable to
KDC470/475 so that you can use KTSync on PC or download a new firmware into KDC from PC (KDC Path).
But, if you want to connect PC with your phone without taking out the phone from the case (Phone Path), you
can set up by pressing DOWN button for 3 seconds. Then KDC470/475 bypasses the communication path to
the phone from PC so that you can access the phone from PC. In the same way, if you press DOWN button for
3 seconds again, it changes to KDC Path again.
While in Phone Path, if it is put on to the charging cradle, it changes to KDC Path right away.
(Note) If using a UHF RFID module with your KDC470/475 + integrated SmartSled® Custom Case, please be
sure the SmartSled® is in Barcode Mode (toggle with UP button) before connecting via USB to PC. Once in
Barcode Mode, the communication path can be toggled with the DOWN button.

3.1 Bluetooth: How to pair KDC470/475 to smart device (Android/MacOS/Windows)
To read barcode data with your KDC wirelessly, the user must first pair the KDC and smart device via
Bluetooth. If previously paired and no changes have been made in the smart device’s Bluetooth settings, the
smart device will always recognize the KDC that has previously been paired. However, if changes have been
made, the user may need to go through the pairing process again.
To move forward, you should scan the Bluetooth Mode barcode first.

3.1.1 Two Bluetooth Profiles
There are two different methods to pair KDC470/475 to a host device.
a) HID (Human Interface Device): one-way communication with the host device. The KDC wedges data to
the Android keyboard. (HID Keyboard)
b) SPP (Serial Port Profile) or MFi (Made for iOS): two-way communication with an application on the host
device. The KDC can send data or receive commands to or from the host device. So, any application is
required to use KDC. One example is Koamtac’s KTSync, which is developed using Koamtac SDK
(Software Development Kit). When connected to KTSync application, the data can be wedged to the
keyboard. (KTSync Keyboard)
3.1.2 HID Normal (Basic Mode) - Keyboard Wedge or HID Keyboard
a) Scan the HID Normal & Pairing bar code on the quick manual provided with the scanner. If done
correctly, the LED on the side of your KDC470/475 will begin blinking orange.
