Question:
I can?t seem to get the EPad working for Klip100... It?s installed as an Active Etherpad, plugged in to a port on a TP-Link router at the complex. Apart from Port 23000 I set in the etherpad, do I also need to specify the IP address of the SDG server? What else should I check on my side? This is the first Epad installation we?re doing, so we?ll need some advice

Answer:
There is some documentation on etherpad installation at http://www.sdgtech.co.za , perhaps you want to check it out?
As for troubleshooting: yes the etherpad is configured via web interface, to connect to our server's IP, on a specific port, as specified when you added the etherpad. It is also a good idea to set the etherpad up on a static local IP address, making sure you use the correct Gateway IP address.
In short, if you can connect your laptop to the same physical port with the same static IP settings and connect to the pnpscada server over TCP on the remote port specified, it should also work on the etherpad.
You can plug in your notebook and try to ping the remote server, try to ping the gateway IP, etc., as normal for any TCP/IP network. However, some network administrators also block ping. So the best is to use telnet to an IP and port, or a raw TCP connection with Putty to the IP and port.
Before you try to connect, go to Comms Monitor and try to read in the meter: the server will then create the server socket for you to connect to: after you have connected, you should see on your computer the string the server sends to the meter, and anything you type in should appear in the Comms Monitor web page.
It could be helpful if you can call in the meter on your cell phone at this stage, since your notebook will be needed to communicate over the LAN, pretending to be an etherpad.
