Appendix A
TCP/IP Protocol: A Brief Overview
NOTE: This information is provided to help Airnet II 4-Channel particle sensor users who
are not familiar with TCP/IP protocol understand more about the sensor
configuration process. It is not a substitute for the guidance of your network
administrator.

TCP/IP's Network Layer

TCP/IP's Internet Protocol or IP is designed to interconnect packet-switched
communication networks to form an internet.
In summary, the IP protocol's main functions are:
•
Provide the basic unit for data transfer
•
Addressing
•
Routing
•
Fragmentation of datagrams

Ping

TCP/IP systems can use a utility named PING (Packet InterNet Groper) to test station
and network integrity. The TCP/IP-32 add-on protocol for Microsoft Windows for
Workgroups 3.11 includes a PING function that must be run from a Windows DOS
window.
To use the Windows TCP/IP PING:
1. With Windows running, open a DOS window by double-clicking on the MS-DOS
Prompt icon.
2. At the DOS prompt, type PING <IP ADDRESS> (using the address of the device
for which you wish to test your computer's LAN communications).
The PING utility will report whether or not the other device responded, and what the
response time was.
