Subnet
A small network within a larger network. For example, a TCP/IP network might be a subnet of a venue’s network, which could include computers throughout the building, or a network might be divided into subnets. For example, in a large installation, there may be one subnet per rack or room.
DHCP (Dynamic Host Configuration Protocol)
This is a protocol for automatically assigning IP addresses to devices on a network. With dynamic (DHCP) addressing, a device might have a different IP address every time it connects to the network. DHCP relies on a DHCP server to assign and manage IP addresses.
Auto IP
If DHCP fails, the PCM92 selects a number and looks for collisions. If no collisions are found, the PCM92 accepts that number. If collisions are found, the PCM92 randomly selects another number and tries again.
Connecting the Computer Directly to the PCM92
Assumptions:
•Using
•Computer has a working Ethernet network adapter.
•You have administrative rights so that network settings can be changed if necessary.
1.Connect the included Ethernet cable to both the PCM92 and the com- puter.
2.Apply power to the PCM92 and wait for it to boot.
3.Open the standalone application.
Setup of a Simple Isolated Ethernet Network Using
DHCP
Assumptions:
•Using
•Computer has a working Ethernet network adapter.
•You have an Ethernet switch/router with DHCP capability and Ethernet cables for each connection needed.
•You have administrative rights so that network settings can be changed if needed.
•The Ethernet network consists of exactly one computer that will be used to run the PCM92 configuration software and one or more PCM92 units.
1.Connect the computer and any PCM92 to the switch hub using normal Ethernet cables.
2.Apply power to all PCM92s and wait for them to boot.
3.With DHCP enabled, the Ethernet switch/router should assign an IP address to each of the devices including your computer.
4.The PCM92 units should come up in the main window.
Virtual Private Networks (VPN)

Virtual private networks (VPN) provide an encrypted connection (or tunnel) between networks or between a network and a user over a public network
