Q1. Why won't the CPU Module LINK LED come on when connecting to the meter via the Ethernet?
A1. The LINK light indicates good electric connectivity between two LAN ports. It also indicates proper polarity in
the Ethernet connection.

: When using a hub between the meter and the PC, a straight-through patch cable is
required between the meter and the hub and a straight-through patch cable is required between the hub and
the PC. Do not connect either the meter or PC to the hub UPLINK port. Most hubs do not allow use of the port
immediately next to the hub UPLINK port when the UPLINK port is used to connect the hub to a LAN. Ensure
the meter and PC are not plugged in to a hub non-usable UPLINK port.
Verify that the meter is powered up by checking that CPU Module LED 1 is on (either solid red or green). If the
LED is not on, check power to the meter. If the LED is on, check the Ethernet cable connections.
Q2. My CPU Module LINK LED is on but I can't communicate with the meter using Ethernet. What's wrong?
A2. If you are connecting for the first time, refer to
Section 2.1.1
for instructions on initial communication (via
Ethernet) setup.
If you are using the Daniel MeterLink program, ensure that the optional Ethernet connection is enabled.
Ensure that the meter's DHCP server is enabled (CPU Module switch
OFF
). Verify that the PC has received an IP
address from the meter as follows:
•
bring up DOS prompt window (Start|Run|(type)cmd)
•
in the DOS prompt window, type ipconfig.
You should then see something like:
