The IP stacks in some PC operating systems, such as Microsoft Windows, often
do not respond quickly enough to the ICMP Echo packets to obtain an accurate
assessment of your network throughput. When running the Ping Fill test to a
Microsoft Windows system, your results may be slightly lower than normal
throughput.
5. How do I read the configuration from a device if I cannot see the unit in the
local scan window?
The only devices that will display in the Configurator local scan window are the
units in the same subnet as your management computer. For example your PC
has an IP address 64.22.33.13 with a subnet mask of 255.255.255.0 and your
device has an IP address of 65.23.11.2 with a subnet mask of 255.255.0.0. The
device in question would not display in your local scan window.
Even though you may be able to ping the unit it may not be visible in the local
scan window. In the Configurator, select the file menu, and then open remote
config and then type in the IP and the password. It may be necessary to select
the "this device is in my local subnet" check box to actually read the
configuration from the unit. Attempt to read the configuration with it un-checked
first. If the configuration cannot be read try with this box checked.
6. I seem to have lost or forgotten the read/write password to manage my
product.
How can I get back in to manage the unit?
If the read/write password has been lost or forgotten, there is only one thing that
can be done about this in order to be able to manage the unit again. The unit
must be put into force reload mode and the firmware must be reloaded. All
configuration settings will be lost. Physical access to the unit is required in order
to accomplish this procedure.
7. I am performing a wireless link test from a CSU Secure Data mode and one
of my CSU Secure Data modes on the other side of my base station is
showing up, is this a problem?
It is a normal function to be able to see the other units in the wireless link test
this way. This shows you what devices are within range so that the radio can
"hear". As long as the units are set as Secure Data mode CSU Secure Data
modes, there is no way they will actually be communicating with each other.
They are receiving radio signals from each other that they have to interpret and
dump. This is not an optimal solution and should be changed when it is practical
to do so by isolating antennas, changing polarity or reducing output power if
possible.
