7.3.1
Additional Information on Ethernet Connections
Setting up an Ethernet connection may require some additional diagnostics. Listed below are
System tools that may provide assistance. Generally, if there is a connection problem, it will either
be a hardware problem, such as a bad or unconnected cable, or a setup problem in either the PC
or 1133A. For extra help with configuring Ethernet settings, see Appendix A.
7.3.2
Check the Computer Network Settings with ipconfig
In Windows 2000 or XP, type “ipconfig” at the command prompt.
It should list the DNS
information, IP address, Subnet Mask and Default Gateway.
7.3.3
Ping the 1133A Port
One method of checking to see if a device has a valid connection through a network is to ping
it to see if it responds. Below is an example of “pinging” an 1133A Ethernet port at IP address
192.168.000.232, on the same network as the computer.
C:
\
ping 192.168.0.232
Pinging 192.168.0.232 with 32 bytes of data:
Reply from 192.168.0.232 bytes = 32 time = 15 ms TTL=64
Reply from 192.168.0.232 bytes = 32 time = 4 ms TTL=64
Reply from 192.168.0.232 bytes = 32 time = 9 ms TTL=64
Reply from 192.168.0.232 bytes = 32 time = 12 ms TTL=64
Ping Statistics
Packets sent = 4, Received = 4, Lost = 0 (0% lost)
Approximate round trip times in milliseconds:
Minimum = 4 ms, Maximum = 15 ms, Average = 9 ms
If there is no connection, then the ping test will time out, four times. Other connection issues
may be present, and results returned from the test. There must be a valid response from “pinging”
the 1133A for it to communicate using PSCSV.
Additional information on trouble shooting Ethernet connections is given in Appendix A:
Working with Ethernet Connections.

Configuring Measurement Parameters
Measurement Parameters include all of the values stored in 1133A for defining the measured
electrical system, for calibration, to compensate for measuring the primary currents and voltages,
and many other constants. These are depicted in Figure 7.3, which has a number of selection tabs
described below.
◦
DSP Mode:
Sets the measured electrical system values (e.g.
voltage, current, system
phase(s) and nominal frequency. See also Figure 5.11 on page 31 for display examples.
◦
CTPT:
Sets calibration points for current transformers and potential transformers
