Send Ping: Send a ping to detect host communication errors. This can be set when "Event Transmission(UDP)" is
selected as "1" in the No. When this check box is selected, the KW2D Series Smart RFID Reader sends a
ping to the destination at the specified interval (1 to 10 seconds). If the Send Ping is not successful for
10 seconds or more, a host communication error will occur and the LED (red) will blink.
For Event Transmission, select the
Send Ping
check box to detect a communication failure with the host
device as a host communication error.
Use Received Data: The KW2D smart RFID reader displays the detection result based on the response data from the
host device. This can be set when “Event Transmission(UDP)” is selected as "1" in No. When this
check box is selected, the host device must return the response data to the KW2D Series Smart
RFID Reader within two seconds after receiving the transmitted data. If the KW2D Series Smart
RFID Reader does not receive the response data in time, the detection result will be a host
communication error.
