Connecting via dial up (modem or ISDN) link

When you use a modem or ISDN link to make the connection, the CPU IP uses standard network protocols to create a private two-device network. This approach ensures consistency and allows you to use exactly the same VNC viewer or browser to view the hosts systems. This is achieved using PPP (Point to Point Protocol) and means that you need to use a dial-up networking method to initiate the connection. Such software is standard with operating systems such as Windows, Linux and Mac OS.

To initiate a dial up link

1Using a system that has a modem or ISDN adapter installed, locate the dial-up networking option on your system. Please refer to your system documentation for more information.

2Using the dial-up networking option, enter the telephone/ISDN number where the CPU IP can be contacted.

3Initiate the call and when the link is made, continue with either the standard VNC viewer or browser connection.

Note: For the viewer network connection address, you must use the IP address that the admin user has set as the Server address (or PPP server IP address) within the Modem configuration screen.

Downloading VNC viewer from the CPU IP

The CPU IP has the ability to distribute its own VNC viewer application.

To download the VNC viewer 1 Open your Web browser.

2Enter the network address where the CPU IP is situated (in the form: http://192.168.0.3) and make the link.

3In the opening CPU IP screen, click the link that offers to download the secure VNC viewer ‘from the unit’.

4 Save the download file (vncviewer.exe) to your system.

5Select and run the downloaded file and then connect to the CPU IP using the VNC viewer application.

If you need to enter a port number

Usually, when you make a network connection to the CPU IP (either using the VNC viewer or a Web browser) you simply enter the IP address, i.e. 192.168.0.3. However, if a special configuration is necessary, then you may be asked to specify a port number as well as the IP address.

What is a port?

To enter a port number in a Web browser

1Enter the required IP address in the usual Address box, i.e. http://192.168.0.3

2At the end of the IP address, add a single colon and then enter the port number (in this example, the required port number is 8000),

i.e. http://192.168.0.3:8000

3 Continue with the standard Web browser instructions.

To enter a port number in VNC viewer

1Enter the required IP address in the usual ‘Server’ box, i.e. http://192.168.0.3

2At the end of the IP address, add two colons and then enter the port number (in this example, the required port number is 115900),

i.e. http://192.168.0.3::115900

3 Continue with the standard VNC viewer instructions.
