2.3 How to Install/Uninstall the Smart Device into the Integrated Case (Android/iOS)
This only applies to KDC480/485 integrated charging case (SmartSled Custom Case). To install the smart
device, please follow the steps below.
a) Bend top of SmartSled Charging Case back.
b) Slide device into case toward connecter.
c) Pull top of case over device.
d) To remove, bend top of SmartSled Charging Case back (careful not to bend smart device) and slide
device out.
2.4 How to Connect PC with KDC or Phone
This functionality only applies to KDC480/485 integrated charging case (SmartSled Custom Case).
The KDC480/485 automatically sets up a communication path with PC when you plug in USB cable to

QG_KDC480/485_20220630 p8
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 KDC480/485 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 KDC480/485 + 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.

Bluetooth Pairing
Connecting your KDC using Bluetooth is made easy with the pairing barcodes below
4.1 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 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 int o an application. To gain access to
the SDK, please complete the form here: https://www.koamtac.com/sdk/
4.2 Bluetooth Pairing a KDC480/485 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 p rofile is right for you, please refer
to Chapter section 2.1.

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 KDC480/485 listed by serial number in brackets that
matches the serial number found on the back side of the KDC480/485. KDC480/485 will
beep upon connection. Now it is ready to use.

device. From the list, select the KDC480/485 listed by serial number in brackets that
matches the serial number found on the back side of the KDC480/485. KDC480/485 will
beep upon connection, but you should launch KTSync or your application and select
KDC480/485 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 launc h
KTSync or your application and select the KDC480/485 listed by serial number in brackets
that matches the serial number found on the back side of the KDC480/485. KDC480/485
