Receive Performance Verification
The receive performance verification procedure requires a software tool to measure the number of uncorrupted packets
received by the UUT. Packet error rate is then calculated based on the number of packets sent and the number correctly
received.
Packet Error Measurement with NodeUtil
A utility called NodeUtil (nodeutil.exe) is used to measure packets correctly received by the UUT. The NodeUtil
software allows a computer to remotely query the UUT and extract its status, including the number of uncorrupted
packets received by the device. NodeUtil is available free of charge from the Echelon Web (go to
www.echelon.com/downloads
, select the Development Tools category and then select the NodeUtil Node
Utility).
Figure 7.9 illustrates the setup for the computer running the NodeUtil utility. The computer should contain an Echelon
PCLTA-20/SMX card equipped with a PLM-22 SMX transceiver (alternately a U-20 USB network interface can be
used for C-band testing). The PCLTA-20/PLM-22 is connected to the isolated power line via a PL-20 power line
coupler. Ensure that the proper drivers for the PCLTA-20 and computer operating system are installed. Refer to the
L
ONWORKS PCLTA-20 PCI Interface User’s Guide for detailed driver setup and operation information.
The verification procedure below describes how to use NodeUtil to access the UUT over the power line.
The startup screen for NodeUtil is shown below. Refer to the “ReadMe Node Util” file for additional setup information.
