CHAPTER 2 NETWORK CONFIGURATION

Network parameters need to be configured into the Host and Client systems, and sometimes into other network devices.

Ask to your Network Administrator for :

Network parameters

• The Gateway, if any. 
• The Subnet Mask.

Host parameters

• The Host Computer IP address.
• The Telnet port (standard is 23).

Terminal parameters

• The PDA IP address.
• The ESS id used by the 802.11 radio network.
• The Authentication if any and Encryption if any.

2.I Network

2.I.1 IP Addressing

IP addresses have 4 decimal numbers from 0 to 255. Addresses are provided in "dotted decimal" form. One part of the IP address (the left) is "the subnet" and the other part of the IP address (the right) is "the computer". 

The subnet Mask determines which numbers of the IP address belongs to the left or the right part. The Subnet Mask must be the same across the network.
Subnet masking have 4 decimal numbers, usually 0 or 255. Subnet masking means the part of the IP address that are "the subnet", and the part of the address that are "the computer". Usually subnet mask is:

• 255.0.0.0 (The first number is "the subnet", the three others are "the computer").
• 255.255.0.0 (The two first numbers are "the subnet", the two others are "the computer").
• 255.255.255.0 (The three first numbers are "the subnet", the other is "the computer").

2.I.2 Gateway

See the address of the Host computer, the terminal's and the subnet mask to determine if they are in the same subnet or not.
If the Host computer and PDA Wi-Fi terminals are in the same subnet, no gateway is needed.
If the Host computer and PDA Wi-Fi terminals are not in the same subnet, a gateway is needed. The gateway must belong to the same subnet as that of the terminals.

2.II Host

Start the Telnet host "service" or "daemon". 
You may verify the host address by the "ping" utility from a Windows-based PC.
You may verify if the telnet service is available, using a "telnet" client program from any Windows-based PC.

2.III Terminal

The terminal is configured in two ways :

The network and terminal parameters, through the RF utility:

• The Gateway, if any. (Configuration depending on your PDA model, see the corresponding Product Reference Guide).
• The Subnet Mask. (Configuration depending on your PDA model, see the corresponding Product Reference Guide).
• The PDA IP address. (Configuration depending on your PDA model, see the corresponding Product Reference Guide).
• The ESS id used by the 802.11 radio network. (Configuration depending on your PDA model, see the corresponding Product Reference Guide).
• The Authentication if any or Encryption if any.

Usually the RF utility is called by clicking the RF icon (depending on your PDA model) at the bottom right corner of the Today screen.

 RF icon, this is only an example

See Appendix D - PDA NETWORK CONFIGURATION

RF and IP configuration are managed by the operating system and are not "persistent" (cleared at cold boot). In some platforms, persistence of RF and IP settings, and "cloning" to other terminals will be done by iPDA during program installation procedure.

The Host parameters, by the WTnCeVt configuration menu.

• The Host Computer IP address.
• The Telnet port (standard is 23).

These parameters are initialized by the configuration files (see Chapter 5 for the VT configuration file WTnCeVt.Cfg and Chapter 6 for the common configuration file _WTnCE.Cfg) and may be changed by the user.
