7.4 Troubleshooting Communications

The Communications Analyzer (via Daniel MeterLink Tools> Menu>Communications Analyzer menu path) displays communications between Daniel MeterLink and the ultrasonic meter. This utility can be useful for troubleshooting communications to the meter. It displays many of the TCP/IP commands between Daniel MeterLink and the connected meter.

For troubleshooting communications with the Field Communicator (375) for the HART® Protocol, refer to Section 5 of the Emerson 375 Field Communicator User’s Manual P/N 00375-

0047-0001, Rev D. This manual may be downloaded from the following location:

For troubleshooting communications with AMS™ Suite, refer to the AMS™ Books Online help documentation and support at the following web site:

7.4.1Unable 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.

Refer to the Daniel MeterLink Ultrasonic Meter Software Quick Start Manual (P/N 3-9000-763) for phone and modem details. These manuals may be downloaded from the Daniel website:

7.4.2Unable to Connect to Meter

If you receive the error message “Unable to connect to meter” when trying to connect to a Mark III Series 100 Option Board, refer to the following:

Ethernet ConnectionsDirect Serial ConnectionsEthernet Connections

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 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.
