IP address corresponds to dynamic IP address assigned by DHCP server. You can choose the static IP
address (Default 192.168.1.200) or a dynamic IP address. Default setting is static IP address. The port 7090 is
used by reader for communication. IP address and the port number (over 1024) can be changed by using a
setting command or Web page. If the reader can not detect the DHCP server under dynamic IP address setting,
it will flash the error indicator and start up with static IP address.
