Setting the Login and Timeout Functions of
Ethernet Communications

Explanation

By setting these functions, you can prohibit invalid access from the network to the CX,
authorize setup operations of the CX via the Ethernet network, and disconnect
connections if there is no data transmission for a certain time. To use this function,
however, the Ethernet interface must be configured as described in section 2.3.

If you enable the login function, only registered users can log in to the CX.

Up to 6 USERs can be registered. Certain restrictions exist in using the Setting/
