Unable to Connect Direct Serial or External Serial Modem
If you are using Windows® 2000, Windows® XP or Windows® Vista make sure that you do not
have more than one modem driver installed to the same COM port. Typically this will only be
necessary if you use one COM port to talk direct (serial communications) and use the same COM
port to connect to an external modem. This is an apparent limitation in Microsoft®’s Dial-up
Networking. If more than one modem driver is installed for a particular COM port, Dial-up
Networking will always use the last driver installed regardless of what is selected. The only work
around is to only install one modem driver per COM port on the PC at a time. To check if this is
the issue, follow the steps below.

If you received this message while trying to connect over Ethernet, verify you have the correct IP
address in the Meter Directory record. If the meter is to assign the IP address, make sure the IP
address is set to 192.168.135.100 and that the switch S2 Position 2 is in the
address in the Meter Directory record. If the meter is to assign the IP address, make sure the IP
address is set to 192.168.135.100 and that the switch S2 Position 2 is in the
CLOSED
position on
the CPU board. If the meter has a fixed IP address, verify the IP address, Subnet, and Gateway
are correct in the meter. Verify your wiring to make sure you have a crossed-over cable for a
direct connection between the meter and the computer. If going through a hub, verify that the
computer and meter are connected to the hub with straight through patch cables.
