4 Event Transmission (TCP, UDP)
4-22
KW2D Series Smart RFID Reader User’s Manual
4.1 Overview
The KW2D Smart RFID Reader supports event transmission (TCP) and event transmission (UDP). Hereafter, if there is
no difference between event transmission (TCP) and event transmission (UDP), it is simply called the event
transmission.
When an RFID tag is detected, the event transmission sends the detected RFID tag data to the host device in the
specified format.
For the event transmission (TCP), the KW2D smart RFID reader acts as a client and performs TCP communication with
the host device of the server. The connection with the TCP server is established when the event transmission is
executed, but whether to release or maintain the connection can be selected in the option settings.
The event transmission (UDP) performs the UDP communication with the host device without a connection.
