Open the directory and double click on the file named CDM2.04.16.exe. This automatically installs on the
HW4 PC the driver required to use USB dongle wireless adapter
At this point you can plug-in the USB dongle wireless adapter to the HW4 PC and Windows should
automatically associate the driver to the USB dongle. When this is done you can run HW4 and search for
any available data logger as explained later on in this manual.
3.2 LAN wireless adapter
The LAN adapter is factory configured to use DHCP (Dynamic Host Configuration Protocol) and should be
used only on a LAN that includes a DHCP server such as a router or a managed switch.
With DHCP enabled, the DHCP server senses when a new device (or host) is connected to the network and
automatically assigns / configures the device with the next available IP address. The device is also
automatically configured with the network subnet mask and gateway address. Using DHCP is simple,
guarantees compatibility with the network and eliminates the possibility of conflicting IP addresses.
An IP address assigned using DHCP is also known as a dynamic address. As long as DHCP remains
enabled on the host, the host IP address is subject to change. This is not desirable when using HW4.
Once the dynamic address of the host is known, and communication with the host can be established, we
recommend to change the host IP address to an unused network address and to disable DHCP on the host.
In this manner, the new host IP address is a static address, not subject to change.
When using more than one LAN adapter, make sure to give each one a unique name (or network name).
