Chapter 4. Administration
Direct Access
For security purposes, Direct Access can limit the users attempting to log in to RAW TCP ports or Real COM ports (seeOperating Mode, page 34).
If no IP addresses are specified on this page, anyone can open a TCPIP Telnet session to a RAW TCP or Real COM port by specifying the IP address and port number of the port – without having to specify a Username and Password.
Once specific IP addresses are entered here, however, only users logging in to the SN0108 / SN0116 from one of those IP addresses can have access to the RAW TCP or Real COM ports without having to specify a Username and Password.
Note: Ports must be designated as a RAW TCP or Real COM ports under the Port Config settings. See Operating Mode, page 34, for further details.
