46 741 and 751 Mobile Computers (Windows Mobile 5.0) User’s Manual
Configuring 802.11 Radio Communications
The 751 Mobile Computer has an internal 802.11 b/g radio to transfer
data using wireless communications. This section of the manual assumes
that you have already set up your wireless communications network
including your access points. If you are using a UDP Plus network, have
your Intermec Application Server communicate with a host computer.
Your computer supports these network protocols:
•TCP/IP
• UDP Plus
The next sections explain the parameters you need to configure for the 751
to work in your wireless network.
Configuring the Network Parameters for a TCP/IP Network
In a TCP/IP network, the 751 communicates with a host computer directly
using TCP/IP. The access point acts as a bridge to allow communications
between the wired network and the wireless network.
To use wireless communications in a TCP/IP network
1 Go to Start > Settings > the Systems tab > Intermec Settings.
2 Configure these network parameters on each 751 in the network:
• Network name (SSID)
• IP settings (if not using DHCP)
3 Make sure that the 751 is talking to the network and that the network
can see the 751.
4 Configure security. For help, see “Configuring Security on the Wireless
Network” on page 47.
The easiest way to configure the network parameters on the 751 is to use
Intermec Settings. For help, see “Configuring the Computer With
Intermec Settings” on page 38.
Configuring the Network Parameters for a UDP Plus Network
In a UDP Plus network, the 751 communicates with a host computer
through the Intermec Application Server. The Intermec Application Server
translates UDP Plus packets on the wireless network into TCP/IP packets
on the wired networks and vice versa. The access point acts as a bridge to
allow communications between the wired network and the wireless
network.
To use wireless communications in a UDP Plus network
1 Go to Start > Settings > the Systems tab > Intermec Settings.
2 Configure these network parameters on the 751:
• Network name (SSID)
