1 Introduction
BlueGate™2100 provides access to a local area network (LAN) using wireless
technology. It is Bluetooth Specification 1.1 compliant.
Devices that can access the network through BlueGate 2100 are Personal Digital
Assistants (PDAs), computers, or other Bluetooth-enabled devices that support the
industry standard LAN Access using PPP Profile (LAP) portion of Bluetooth
Specification Version 1.1.
Configuration information is saved in internal Non-Volatile Random Access Memory
(NVRAM) and preserved even when power is lost.
An on-board, internal Web server is accessed to set up, diagnose, and configure
BlueGate 2100.
A browser1is used to access the internal Web server from a computer on the same
network subnet.
From the browser, access the internal Web server to:
• Configure BlueGate 2100 for proper network operation.
• Change the user-friendly device name of BlueGate 2100.

BlueGate 2100 Installation
July 26, 2001 WIDCOMM, Inc, Proprietary and Confidential 3
3 Installation
Before installing BlueGate 2100, you should be familiar with basic local area network
(LAN) and Bluetooth concepts.
For a non-technical overview of key Bluetooth concepts refer to Appendix A—An
Introduction To Bluetooth.
3.1 POWER CORD AND ETHERNET CABLE INSTALLATION
1. Mount BlueGate 2100 on the wall or ceiling or place it on a flat surface away
from heat, moisture, open flames, microwave devices, and 2.4 GHz
telecommunication devices (for example, 802.11b LAN adapters). See also the
RF Exposure Statement on page i.
NOTE: See Section 3.2 for additional information on mounting BlueGate 2100 on the wall
or ceiling.
2. Use the Ethernet cable provided in the kit to connect BlueGate 2100 to the local
area network. See Figure 1 for the location of BlueGate 2100’s Ethernet jack.
The Ethernet cable can be plugged into a network switch or network hub, or into
a hardwired wall jack that connects to the network. Consult your network
administrator if you are unsure of where or how to establish a physical
connection to the network.
Place the other end of the Ethernet cable securely into the Ethernet jack (RJ-45
connector) on BlueGate 2100. The Ethernet LED blinks off and on depending on
Ethernet activity.
Route the network cable away from other cables that may cause electrical
interference. Avoid routing the cable through areas where it will be stepped on,
tripped over, or damaged in any way.
NOTE: Telephone cables often use the same type of connector as network cables; some
wall plates, especially in office environments, have both telephone and network
jacks in the same wall plate. When connecting through a wall plate of this type
verify the physical connection between the jack and the network.
3. Insert the small circular power plug into the power jack on the back of
BlueGate 2100 and then plug the power supply into a wall outlet (120-220VAC,
60-50 Hz). When power is applied the bottom light emitting diode (LED) will
blink for 6 seconds and then stay on continuously.
If the LAN is 10Base-T or 100Base-T and a Dynamic Host Configuration Protocol
(DHCP) server is available, BlueGate 2100 is ready to use.
Figure 1: BlueGate 2100 connector and LED locations.

3.2 WALL OR CEILING INSTALLATION
Required materials and tools:
• Adhesive tape.
• #2 Philips head screwdriver or drill/driver with Philips bit.
Install template and drywall anchors:
NOTE: The self-drilling anchors are for drywall
installation only. The anchors are not
recommended for use in acoustical ceiling
tiles or other types of wall / ceiling materials.
1. Decide where BlueGate 2100 will be mounted keeping in mind:
 The lengths of the Ethernet cable and power cord.
 The location of the Bluetooth-enabled devices that will use BlueGate 2100’s
service. Typically devices must be within 30 meters of BlueGate 2100; walls
and other obstructions may shorten this distance.
2. Tape the mounting template to the installation location and use a nail or other
small pointed object to mark the locations of the screw anchors.
3. Remove the template.
4. Using a screwdriver or drill/driver, install the self-drilling drywall anchors:
a) Place the screwdriver or driver/drill into recess of anchor.
b) Press the anchor into the drywall while turning the anchor clockwise until it
is seated flush with the wall.
Mount BlueGate 2100:
1. Slide the covers outward from the center of BlueGate 2100 to remove them.
NOTE: Do not lift or pry the covers.
2. Complete the power cord and Ethernet cable installation described in Section 3.1
(also described in the Start Here booklet).
3. Hold the base of BlueGate 2100 firmly against the wall or ceiling aligning the
device’s screw holes over the wall anchors.
4. Using the four (4) included Philips head screws, secure BlueGate 2100 to the
wall anchors.
5. Replace the covers.

BlueGate 2100 Find BlueGate 2100’s IP address
July 26, 2001 WIDCOMM, Inc, Proprietary and Confidential 6
5 Find BlueGate 2100’s IP address
BlueGate 2100 is set up and configured through an internal Web server.
To access BlueGate 2100’s internal Web server you must know the IP address assigned
to BlueGate 2100.
In a Dynamic Host Configuration Protocol (DHCP) environment, BlueGate 2100’s
IP address is dynamically assigned by the DHCP server.
The FindIP application that discovers BlueGate 2100’s dynamically assigned IP address
is included on the BlueGate 2100 compact disc (see Section 5.1).
In a non-DHCP environment BlueGate 2100 defaults to a static IP address that can be
used to access the internal Web server (see Section 5.2).
A Java™ applet2is included on the compact disc for environments not operating under
Windows®. For more information on the Java applet, see Appendix C—Find IP address
in a Non-Windows Environment.
5.1 IP ADDRESS IN A DHCP ENVIRONMENT
To discover the dynamically assigned IP address:
1. Insert the BlueGate 2100 compact disc into your CD-ROM drive and wait a few
seconds for the FindIP.exe application to auto-start. If the application does not
auto-start, from the Windows taskbar click Start > Run > Drive Designation
Letter (for example D:\) > FindIP.exe.
2. On the Welcome to Widcomm’s BlueGate Wizard screen, click Next.
3. When prompted, enter the Media Access Control (MAC) Address from the serial
number label on BlueGate 2100 (Figure 2) located beneath the covers (Figure 1)
and click Next.
4. FindIP returns the IP address. Select the check box to automatically open the
internal Web server home page and click Finish.
NOTE: The FindIP application uses a UDP broadcast packet to interrogate BlueGate 2100
for its assigned IP address. UDP packets are not routed; be sure that a router is
not between BlueGate 2100 and the computer running FindIP.
Section 6 describes how to complete the logon process.
Figure 2: BlueGate 2100's serial number label.

address in a Non-Windows Environment.

BlueGate 2100 Find BlueGate 2100’s IP address
July 26, 2001 WIDCOMM, Inc, Proprietary and Confidential 7
5.2 IP ADDRESS IN A NON-DHCP ENVIRONMENT
BlueGate 2100’s internal Web server can also be accessed using a static IP address.
When DHCP is enabled (factory default), the DHCP attempt must first timeout before
attempting to access BlueGate 2100’s internal Web server using the static IP address.
After the DHCP timeout (120 seconds), BlueGate 2100 uses the static IP address.
NOTE: The factory-default static IP address is: 192.168.0.1.
To access BlueGate 2100’s internal Web server using the static IP address, create a two-
node private network between a single computer and BlueGate 2100:
1. Connect BlueGate 2100 and the computer (see Figure 3):
 Solution One: use standard Ethernet cables to establish a connection through
a switch or hub.
 Solution Two: use a crossover cable to create a direct connection. Figure 14
on page B-1 shows the connections for a crossover cable.
2. Configure the computer:
 Static IP address of 192.168.0.2.
 Subnet mask of 255.255.255.0.
3. Start the browser and enter http://192.168.0.1 in the address field.
4. Click
Go or press the Enter key.
Section 6 describes how to complete the logon process.
NOTE: The default static IP address for BlueGate 2100 can be changed through
the Configuration > Network Settings option. If BlueGate 2100’s static IP address
has been reconfigured, enter the current address.

addresses it needs to function properly.
The default is Dynamic Host Control Protocol (DHCP) enabled.
DHCP Enabled:
When DHCP is enabled:
• BlueGate 2100 is assigned an IP address by the DHCP-enabled LAN server.
• The LAN server handles gateway, subnet, and DNS addressing.
• All of the fields in the Network Settings Information configuration window
appear dimmed and are unavailable.
To enable DHCP select the Enable option and click OK. BlueGate 2100 must be
restarted for the change to take effect. Restart is explained in Section 7.6.1, page 24.
DHCP Disabled:
To disable DHCP select the Disable option, enter the addresses in dotted decimal
notation (000.000.000.000), and click OK.
BlueGate 2100 must be restarted for the change(s) to take effect. Restart is explained in
Section 7.6.1, page 24.
• IP address: the IP address of BlueGate 2100.
 Example: 10.140.102.8
 Default value: “” (blank field, no entry)
• Gateway: the IP address of the LAN gateway to which BlueGate 2100 will route
packets destined for outside networks.
 Example: 10.140.0.1
 Default value: “” (blank field, no entry)
• Subnet: identifies the subnet to which an IP address belongs.
 Example: 255.255.255.0
 Default value: “” (blank field, no entry)
• Primary DNS (Domain Name System): the IP address of the primary DNS
server. When a DNS server is provided with a hostname, it returns the host’s
IP address:
 Example: 10.140.10.1
 Default value: “” (blank field, no entry)
• Secondary DNS: the IP address of the secondary DNS server—used if the
primary DNS server is unavailable or unable to translate a submitted hostname to
an IP address.
 Example: 10.140.10.2
 Default value: “” (blank field, no entry)
Click OK to store the changes in Saved Settings. BlueGate 2100 must be restarted for the
change to take effect. Restart is explained in Section 7.6.1, page 24.
Click Cancel to abort the changes and return to the previous screen.

7.2.3 Network Address Translation (NAT)
NAT is an Internet standard that allows a network to use one set of IP addresses for
internal traffic and a different set of addresses for external traffic.
BlueGate 2100 handles address translations between the Local Area Network (external)
and the Bluetooth devices (internal) connected to BlueGate 2100.
The default is NAT enabled.
• When NAT is enabled and:
 DHCP is enabled, BlueGate 2100 receives its IP address from the DHCP
server, but internally assigns IP addresses to the devices in its private subnet
(the Bluetooth devices connected to it).
 DHCP is disabled, BlueGate 2100 uses a fixed IP address (Configuration >
Network Settings > Edit > IP Address) on the external network but assigns
IP addresses to the devices in its private subnet (the Bluetooth devices
connected to it).
• When NAT is disabled and:
 DHCP is enabled, Bluetooth devices get their IP address from the
DHCP server.
 DHCP is disabled, the IP address for each Bluetooth device must be
configured in BlueGate 2100’s NVRAM.
If both NAT and DHCP are disabled, a range of usable IP addresses must be configured
manually. If either NAT or DHCP is disabled and then the other is also disabled,
a window opens with fields to configure a range of usable IP addresses.
• In the Range Starting From field enter the starting IP address.
• In the No. of IP Addresses in this range field enter the number (< 255) of
addresses to assign and click the Update button.
7.2.4 Point-to-Multipoint
Point-to-Multipoint refers to BlueGate 2100’s ability to service more than one client at
the same time.
BlueGate 2100’s Point-to-Multipoint ability, when enabled, is limited to seven devices.
To enable/disable Point-to-Multipoint click EDIT, select the appropriate radio button, and
click OK.
The default is Point-to-Multipoint disabled.
NOTE: When Point-to-Multipoint is enabled, Bluetooth devices that only support Point-to-
Point will not be able to connect to BlueGate 2100.

7.2.5 Authorization
BlueGate 2100 authorization is the process of granting or denying access to a resource.
A user name and password are required.
The default Authorization setting is disabled.
NOTE: BlueGate 2100 authorization is not the same as the Bluetooth authorization
described in Appendix A.
If Authorization is disabled (No), all users are allowed to connect to BlueGate 2100.
If Authorization is enabled (Yes), only specific users can connect to BlueGate 2100.
NOTE: Do not enable Authorization if the connecting device does not support security.
To enable/disable Authorization (Figure 8):
1. Click EDIT, select the appropriate radio button (Yes or No), and click OK.
2. Set up authorized users and passwords:
a) Select a user number from the drop-down list.
b) Enter a user name; 1 to 16 alphanumeric characters (case sensitive).
c) Enter a password; 1 to 16 alphanumeric characters (case sensitive).
NOTE: User names and passwords are case sensitive.
3. Repeat steps 2a through 2c for each user (up to seven) to be authorized and then
click the Update button.
BlueGate 2100 can store up to seven authorized user names (including the administrator)
and their associated passwords.
The administrator is the first name in the list (User zero); the default setting is
user name = widcomm and password = admin. The remaining user names/password
entries are numbered User one through User six. The authorized user name and password
information also can be re-configured through the command line entry feature (see
Sections 8.16 and 8.25).
