Section 3: Operation- Telnet Access
The features outlined for the RS-232 port can also be accessed via the Ethernet network connection. This feature can save a trip out to the
remote CM16a with a laptop computer as long as the network and software are fully operable.
The Telnet “session” is a standard Windows program. Consult Windows documentation for information reagrding the specifics of Telnet.
It is a very straight-forward program to start and use.
This is the basic procedure for opening a Telnet session:
1- To open the Telnet program. Click START, select RUN, type TELNET in the text
box & click OK.The blank Telnet screen should look similar to the example to the
right.
2- Click on the “Connect” menu header; the drop down menu items will appear.
Choose the “Remote System” option.
3- The “Connect” window then opens. You will need to enter the IP address of the
CM16a that you want to communicate with. Determine the IP address of the
specific CM16a and enter it in the
Host Name:
field ( the numbers in the screen-
shot to the right are EXAMPLE ONLY!). Enter the address in four numeric groups
seperated by periods.
(NOTE: Port:
&
Term
Type:
settings must be as shown)
4- Click on the “Connect” button. If the address entered was correct and network
communications with the CM16a are successful, the Telnet session should open
as shown below. The IP address number that appears at the top of the window will
be different than shown; it will match the IP address that you entered for the
CM16a that you are communicating with.
5- Now you have the same options that are available in the Serial Port I/O (RS-232)
interface section (see pages 25-27).
