Hardware Connection
Dynamic Host Configuration Protocol (DHCP) is a system that allows each component on a computer network to automatically
obtain the network address information required for Network Interface Devices to communicate with one another. With
DHCP enabled on a Local Area Network (LAN), all network connected Tempest Wireless BaseStations will automatically log
onto T-Desk running on a single computer on this network. Automatic addressing includes TCP/IP address, subnet mask, and
default gateway. Most 10/100 Ethernet devices are compatible and should configure properly when the BaseStation is set for
automatic DHCP.
Connect each Tempest BaseStation to the LAN with a standard CAT-5 patch cable and open T-Desk on a computer that is
connected to the same router or server as the BaseStation(s). After about 10 seconds the BaseStation information will begin
to load into T-Desk. DHCP Server is enabled by default in the BaseStation, but through the BaseStation Tech Menu, manual
addressing can be selected, or addressing can be disabled. The following TCP/IP modes are available via the BaseStation for
connection to T-Desk:
» Disabled - Disables LAN connection on rear of BaseStation
» Manual - allows for manual entry of IP address, subnet mask, and default gateway
» DHCP Server - this enables the BaseStation to act as a “server” to a single PC. Use this mode if you are connecting a
BaseStation directly to a PC.
» DHCP Client - this enables the BaseStation to become a “client” of a network. This mode should be used when a router is in
use to auto-assign IP addresses.
Any change to the TCP/IP mode requires the BaseStation to be powered off and back on for changes to be implemented.
Newer computers that have Auto-MDIX capability can use either standard CAT-5 cable or a crossover cable. Auto-MDIX detects
the connected cable type and configures the computer connection appropriately. Otherwise a crossover cable is required
between the BaseStation and the computer.
Advanced users may make adjustments to the TCP/IP address and other settings. Selecting “DHCP” and then selecting
“Manual” will restore the manual setting defaults.
To manually enter IP address information go to the Tech Menu, select “LAN Settings”, and first select “TCP/IP Mode” and
change to “Manual.” Then manually enter the TCP/IP address, and default gateway. The “subnet mask” should normally
be 255.255.255.000 . The MAC address is read-only information. To change the address values, advance to the screen for the
appropriate address. Use the volume knob to scroll through the values and press enter to advance through the three digit
portions of the address. After adjusting the last portion of the address, press enter to save the change.
If T-Desk is closed on one computer and opened on another computer, the new instance of T-Desk should connect to all
BaseStations. Running multiple instances of T-Desk, either on the same computer or on multiple computers on the same local
network, is not supported. If BaseStations are logged onto T-Desk and a second instance of T-Desk is opened, the second
instance will not be recognized by the BaseStation(s) and the BaseStation(s) will remain logged onto the first instance.
