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.

Assumptions:
• Using OS-X 10.4 or later.
• 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.
