Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual
3.23 System Tools
The System Tools Page has a number of tools that help maintain the module firmware and configuration.
TCP Throughput Test Performs a Throughput Test. See section 3.23 ”TCP Throughput Test” below for details
Configuration Summary This option is used to save all the different configuration pages onto one page, for easy viewing.
Page can also be saved (using the File/Save As function on the drop File Menu) for future reference and
emailing module configuration details to Technical Support in the event of any configuration problems.
System Log File Shows an event log of the modules operation, used for diagnosing problems. Page can be saved and
emailed to Cooper Bussmann if requested.“Clear System Log” will clear out the log file and start fresh.
Read Configuration File This option will show the module configuration in XML format. This file can be saved for future reference.
Write Configuration File Any configuration XML files saved using the “Read Configuration” above can be loaded back into
the module
Firmware Upgrade This option is used for firmware upgrades. Load the file using the “Browse” button and when found
press “Send”which will load the file into the module. When completed press “Reset” Firmware upgrade
can be done locally or remotely via the radio.
Reset Resets the module
Factory Default Configuration Loads the Factory default configuration and resets. CAUTION – Doing this will overwrite any
current configuration
3.24 TCP Throughput Test
The performance of a wireless link is best measured in terms of the maximum throughput that can be achieved.The recommended method of
measuring throughput is with the "iperf" utility.Iperf has client and server functionality, where the server waits for a client connection. For wireless
links, it is recommended that iperf throughput testing is performed on point to point links while the remainder of the wireless network is inactive
(i.e., not sending any data).
Iperf is built into the modems for convenience, and allows measurement of TCP throughput with default iperf parameters.For access to all iperf
features and a slightly more accurate result due to module processor overheads etc, it is recommended that iperf be run externally on a PC or
laptop, see Appendix E “External Iperf Test.”

Internal Throughput Test

Before testing ensure that the end node of the Wi-Fi Link that you wish to test has the Iperf Server enabled under the Advanced Radio Settings
page and Saved to Flash and the module has been reset. See Figure 3
Figure 2.
