Cooper Bussmann BU-945U-E 802.11 DSSS Dhcp Client Configuration, Channel Selection, Max Distance

Cooper Bussmann Wireless Ethernet & Device Server BU-945U-E 802.11 DSSS User Manual

Radio Mode	BU-945U-E Only Supports the 802.11 Standard
Background Scanning (STA only)	Enabling this option will allow a modem to periodically rescan for Access Points keeping the connectivity
	page up to date with current system information. Default is off. Note: Enabling this option will slightly
	increase overall radio communications. Rescan time is fixed at 300sec (5min).
Max Distance	Configure the maximum distance the radio signal is expected to travel. This allows the modem to
	Compensate for the flight time of messages as they pass from the transmitter to the receiver, and as the
	acknowledgement messages are returned. Setting this value larger will cause a small reduction in
	throughput. Setting this value too small will cause communications problems over longer distances.
	Default distance is 20km
Save Changes	Save changes to non-volatile memory. Changes will not take effect until module is reset.
Save Changes and Reset	Save changes to non-volatile memory and reset module

3.8 DHCP Client Configuration

DHCP (Dynamic Host Configuration Protocol) allows DHCP Clients to automatically obtain their IP Address at start-up. This simplifies network administration, as there is no need to manually configure each device with a separate IP Address. The BU-945U-E is able to act as a DHCP client. To set the BU-945U-E to acquire its IP address from a DHCP Server, check the box “Obtain IP Address Automatically” on the Network Configuration page.

When configured as a DHCP Client the “Device Name” on the Module Information page will be the module identifier (as the IP address will be unknown) and so should be given a unique name.
