CHAPTER 2 NETWORK CONFIGURATION

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

Ask to your Network Administrator for :

Network parameters

• The Default Router (if any).
• The Subnet Mask

Host parameters

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

Terminal parameters

• The PDT IP address (if not bootp is used).
• The ESS Id used by the 802.11 S24 radio network.

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 Router

See the address of the Host computer, the terminal and the subnet mask to determine if they are or not into the same subnet.
Host computer and PDT S24 terminals will be into the same subnet, in this case, no router is needed.
If Host computer and PDT S24 terminals are not into the same subnet, router is needed. The router address must be into the same subnet than the terminal.

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, by the CFG24 or CFG11 utility :

• The Default Router (if any).
• The Subnet Mask
• The PDT IP address (if not bootp is used).
• The ESS Id used by the 802.11 S24 radio network.

The CFG24 utility is called at boot time in terminal, or be called from the main menu by the "F3 S24 Configuration" Option.

[FUNC] [3]

See APPENDIX E CFG24 / CFG11 Utility.

The Host parameters, by the WTn52 configuration menu.

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

This parameters are initialized by the configuration file (_WTn52.Cfg) and may be changed by the user, by the main menu option "F2 WT Configuration"

[FUNC] [2] (The password is 248)

[CLEAR] Clears the line
[ENTER] save and goes to the next field
[BKSP] Erases the last character
[FUNC] [1] Aborts, do not modify.

This modifications are stored in volatile memory, and are set to defaults configuration values when "Bios Boot".
