BASIC FUNCTIONALITY
AND GENERAL
CONSIDERATIONS
The 1420 Wireless Gateway enables wireless, self-organizing devices to
communicate with each other, and manages security and connectivity. The
gateway is the entry point for wireless device data that is then converted to a
format that is compatible with other systems. System integration is possible
with Modbus, OPC, TCP/IP via Ethernet or serial connections. The 1420
Wireless Gateway enables users to monitor points that were previously out of
reach.
The 1420 Wireless Gateway provides industry leading security, scalability,
and functionality. Users can customize security levels to meet plant standards
via a web-based interface. This interface also allows monitoring of points,
simple trending, customized measuring point lists, basic configuration, and
security management. The 1420 Wireless Gateway allows easy network
expansion; simply set the Network ID and Join Key on the new device and it
will become a part of the existing network.

COMMISSIONING To configure the 1420 Wireless Gateway, a local connection between a
PC/laptop and the 1420 Wireless Gateway must first be established. This can
be done with the crossover cable and a PC/laptop dedicated to the 1420
Wireless Gateway, or a PC/laptop used for another purpose can be
temporarily configured for the task.
HINT/TIP
If a PC/laptop from another network is used, carefully record the
current IP address and other settings so the PC/laptop can be
returned to its original network when configuration of the 1420
Wireless Gateway is finished.
If using a PC/laptop attached to another network, shut down the PC/laptop
and remove it from the network before proceeding to set up the 1420 Wireless
Gateway local connection.
Explosions could result in death or serious injury:
• In an Explosion-Proof and Flame-Proof environment, do not open the 1420
Wireless Gateway electronic housing in an explosive atmosphere.

Configure from the CD The simplest way to configure the PC/laptop for use with the 1420 Wireless
Gateway is to use the Network Assistant installed from the CD included with
the 1420 Wireless Gateway.
Configuration of the gateway is done through its web interface. To access the
device, you must create a private LAN with a subnet of 192.168.1.XX. The
gateway will appear on this LAN at the IP address 192.168.1.10.
1. Using the supplied cross-over Ethernet cable, attach your PC to the
1420 Wireless Gateway’s P1 receptacle.
2. Launch the Network Assistant on your PC/laptop by double-clicking
on its desktop icon or by selecting it from the start menu.
3. If prompted, select the network adapter that you connected to the
1420 Wireless Gateway.
4. Click on the Direct button to establish a direct connection to the 1420.
When you are ready to remove the PC from the 1420 first open the Network
Assistant and select Normal to return the settings of the PC/laptop to their
original values. To check the connection, proceed to step 5 below.
Configure Manually The PC/laptop address and host settings can also be changed manually using
the following procedure for Internet Explorer on Windows XP. The procedure
for other operating systems and web browsers may vary slightly:
1. On the PC/laptop, install the Java Plug-in found on the CD provided
with the 1420. The Plug-in can also be found at http://java.com/
2. Under Network Connections:
a. Select Local Area Connection
b. Right click to select Properties.

Ethernet Network
Configuration:
Once a local connection with the 1420 Wireless Gateway is established,
configuration can be performed using the Gateway’s User Interface. The
settings can be modified to ensure best performance when the 1420 Wireless
Gateway is permanently installed and integrated into the Information System.
If the gateway is connected to a LAN or if more than one gateway will be used
on a private network, the unit will need to be given a new IP address and a
new hostname. A new entry will need to be added to your host file with the
new IP address and Host name using the Network Assistant or the manual
procedure described above.
Address
If you will be attaching the 1420 Wireless Gateway to an internal Intranet, you
may select to have the device obtain an IP address via DHCP or be statically
assigned an IP address (Figure 2-1). Contact your network administrator if
you are not sure which selection is appropriate.
BEST PRACTICES
The 1420 should be assigned a static IP address.
