WLAN Interface
The optional WLAN interface enables a wireless Ethernet connection
(IEEE 802.11b) to the transmitter. The user can establish a virtual terminal session using a Telnet client program such as PuTTY or by using Modbus TCP protocol. When the WLAN interface is in use, serial communication using the RS-232 User Port is disabled.
The interface supports Wired Equivalent Privacy (WEP) and Wi-Fi
Protected Access (WPA, WPA2). For WEP, 64 and 128 bit encryption is supported, with open system or shared key authentication. WPA is used in the Pre-Shared Key (PSK) mode, with either TKIP or CCMP (also known as AES) encryption.
Similarly to the LAN interface, the WLAN interface can use both static and dynamic network settings. If the interface is configured to use dynamic settings, the network where the WLAN interface is connected must have a DHCP server that provides the settings.
The WLAN interface also provides a web configuration interface, which you can access by entering the IP address of the WLAN interface in the
address field of a web browser. See section Web Configuration for LAN and WLAN on page 89.

CAUTION The WLAN interface is designed to be used in trusted network environments (trusted corporate LAN or VPN-based connection over internet). Avoid connecting the transmitter directly to a public network because the device can be attacked by a malicious user through the network.
