CR-SEH
Clicking on Enable IP address control and then Apply brings up the dialog below.
Enable IP address Control
This dialog is used to designate the Allowed IP addresses from which the SEH will accept a telnet session
request. Simply enter an IP address in the “Allowed IP address” field and click “Add IP address. Only IP
addresses designated by this dialog can access the device when IP address control is Enabled.
Access Control Users
This dialog allows the modification of logins and the ability to add new users.
Note: Click on Save Settings to store the system configuration changes in non-volatile FLASH
memory. The user may either click on “Reset” to reboot the processor, click on “Logout” to end the
browser session or simply close the browser window.
Console Port
The CR-SEH can be configured in two other ways. The first is through the console port. The settings for
the console port are 38400 baud, 8 data bits, 1 stop bit, and no parity. The WinSEM program can be used
to set up the CR-SEH through the Console port. The appropriate serial port must be selected in WinSEM,
but the program will automatically set up the serial port. After a few seconds the CR-SEH firmware
version is displayed followed by the
SEM>
prompt.
To set the IP number of the CR-SEH, use the
ip
command.
ip <xxx.xxx.xxx.xxx> {yyy.yyy.yyy.yyy}
Where x is the new IP address and y is the optional netmask number.
Once a valid IP address has been entered in the CR-SEH, a second method to configure the CR-SEH is
through a telnet session. Most telnet programs work with the CR-SEH. Windows 95/98/NT/2000/ME
have a telnet program that works with the CR-SEH. A telnet session can be started by clicking on Start-
>Run if you have Windows 95/98/NT/2000 and the TCP/IP client has been installed. For a CR-SEH with
an IP address of 192.168.0.254, enter the following information in the dialog box:
telnet 192.168.0.254
