3.2 Operation Mode (Single-reading mode vs. Multiple-reading mode)
➢
KDC470 has two operation modes: Single-reading and Multiple-reading.
➢
Single-reading mode means it reads only one tag by triggering the SCAN button once.
➢
Multiple-reading mode means it reads multiple tags by triggering the SCAN button once.
➢
The mode can be changed by scanning the special barcodes below. (The default is a Multiple-reading
mode).
Single-reading Mode
Multiple-reading Mode
➢
In the single-reading mode, it keeps trying to read any tag until timeout value is expired. Once it reads any
tag, KDC470 sends the first read tag information to the host and stops reading.
➢
In the multiple-reading mode, KDC470 sends all the information of the tags which are read until timeout
value is expired.
➢
The application can also change the mode between a single-reading mode and a multiple-reading mode
using SDK.
3.3 Triggering Methods
➢
There are two ways to read a UHF tag: Hardware-triggering and software-triggering.
➢
The hardware-triggering is done by a SCAN button and the software-triggering is done by an API called
from an application using SDK.
3.4 Timeout Value
➢
KDC470 has UHF tag reading timeout value with the same with Barcode reading timeout value. The
default timeout is a 2 second.
3.5 Data Types
➢
KDC470 only sends EPC data to a host by default but sends along with PC data if the user configures
PC+EPC by reading the special barcode below.
Data Type
–
EPC
Data Type - PC+EPC
➢
The data types can also be changed using SDK.
