Usage
3.1 Read RFID tag and Barcode with trigger: Trigger mode
In the trigger mode, with the trigger on the pistol grip, you can read barcodes and UHF tags. If you pull trigger
once then KDC470/475 reads RFID tag and pull trigger twice very shortly then KDC470/475 reads barcodes.
The following are barcodes to enable/disable Trigger mode.
Trigger Mode (E na ble) Trigger Mode (Dis a ble)
3.2 Toggling the Read Mode: Barcode mode vs. UHF mode
With the same SCAN button or the trigger on the pistol grip, you can read barcodes (Barcode mode) or UHF
tags (UHF mode) depending on the read mode and you can change the mode alternatively.
a) On “Barcode mode”, a barcode can be read by a SCAN button or trigger button.
b) On “UHF mode”, UHF tags can be read by a SCAN button or trigger button.
c) By default, it is a “Barcode mode” and also it is set back to a “barcode mode” after the factory default.
d) There are two ways to change the read mode:
1) Press and hold the UP button for 3 seconds
2) Change from within the application using SDK
e) When the mode is changed, the KDC will give a series of beeps to confirm the mode change:
When you enter UHF Mode: 1 long and 2 short beeps
When you enter Barcode Mode: 1 long and 1 short beep
3.3 Changing the UHF Read Tag Modes: Single, Multiple, or Active
This mode only works when the device is in UHF mode. Refer to 3.1 to see how to toggle read modes.
When in UHF Mode, you have the option of scanning in 3 different modes. The modes change in the following
order: Active (default) read -> Single read -> Multiple read. The mode can be changed by pressing the DOWN
button for 2 seconds.
•Single mode: Only one tag is read every time the scan button is pressed.

In Active Mode, if the SCAN button or Trigger button is pressed more than 10 minutes, the read mode
automatically changes from UHF Mode to Barcode Mode to save battery life in the case of the trigger being
stuck in the scan position. This option is enabled by default and may be disabled.
If you need to scan with the trigger depressed for more than 10 minutes, you need to disable the Active Read

•Count = 5: Beeps once every 5 tags read. Example: 2 beeps means you read 10 to 14 tags.
•Count = 10: Beeps once every 10 tags read. Example: 2 beeps means you read 20 to 29 tags.
•Count = 20: Beeps once every 20 tags read. Example: 2 beeps means you read 40 to 59 tags.
•Count = 50: Beeps once every 50 tags read Example: 2 beeps means you read 100 to149 tags.
Scan the barcode on below that corresponds with your preference for Tag Counting.
