Download and Install the software
You can download ELConfig from here. Once you unpack the zip archive, the program can be
placed anywhere on your hard drive such as your Applications folder. The computer you use to
run the software should be attached to the same Local Area Network as one or more Whozz
Launch the software by double clicking on the
An ELConfig window will appear as shown below. Many of the controls
have tool tips that appear when you hover over them and explain what
the control does in more detail.
When the program launches, it will automatically try to discover any Whozz Calling? units
attached to your LAN and list them by serial number in the Select Unit popup menu. If you
attach a new unit to your LAN, you can repeat the Discover process by pressing Discover.
Select the unit you want to configure to see the various Unit Parameters. To change a unit
parameter, select the parameter in the upper table so it appears as the Parameter to Change in
the lower table. Double click on the value you want to edit, enter a new value, and then press
If necessary, change the internal IP address to a valid unused IP address on your LAN before
trying to edit any other parameters. Until your unit is assigned a valid IP address, only Discover
and assigning a new IP address will be available. When you assign a new IP address, ELConfig
uses a special technique to send a message to the corresponding Ethernet MAC Address even
though the IP address has not yet been assigned. [It does this by stuffing the ARP cache.] In
order to do this, ELConfig will ask you for an administrator password. Once a valid IP address is
assigned, ELConfig will send commands to this address allowing you to edit Unit Parameters, or
configure Unit Options as shown below.
The disclosure triangle in the lower left corner of the window opens a log drawer to show
commands you send and the response from any Whozz Calling? units.
