2.7 Installation without Supporting Network Infrastructure
In some situations a network infrastructure may not be available. For example, a scale needing to
communicate to a computer running Microsoft Windows Operating System, and the access point (or
switch) is configured to bridge mode and does not provide DHCP services.
This configuration may require additional support software to configure the scale network interfaces. The
following procedure helps with this type of system.
1. Configure MS Windows as DHCP server
• Install the program
Open DHCP Server
( http://dhcpserver.sourceforge.net/ )
• Edit the configuration file as necessary. The following is a basic configuration:
[LISTEN_ON]
192.168.0.1
[RANGE_SET]
DHCPRange=192.168.0.10-192.168.0.254
[GLOBAL_OPTIONS]
SubNetMask=255.255.255.0
• Set the computer network interface to static IP (example 192.168.0.1).
• Temporarily disable any Firewall running on the computer.
• Start the program as a Windows Service (or standalone depending on specific installation)
2. Cycle power on the scale device.
3. Run the
Scale Discovery Utility
. See Section 2.5 on page 4.
Note
Running the Open DHCP Server on a computer while attached to a network with supporting services can
cause errors. Be sure to disable (or uninstall) the program when not needed. For details consult site specific IT
department.
Figure 2-10 is an example session running
Open DHCP Server
, local computer network interface
configuration and the
Scale Discovery Utility
.

Now that the scale is configured on the network, there is access to the scale for host communications via port 2101.
The host commands provide the ability to read all aspects of weight data: Current, Gross, Net, Tare weight, Total
weight, and statistics. In addition, the host command language provides the ability to configure settings in the crane
scale.
Note
Complete details about host communications can be found in the Crane Scale manual.
