Table 4 shows the codec configuration settings for example 3. See “Configure Network
Settings” on page 16 to make these settings.

Configuring Network Settings
NOTE: Perform the procedures in this section before you connect any codec to a
network.
Connect a computer to the Remote port (a) on each unit to configure the network settings
for that unit. Set one codec in the system as the controller.
See”Serial Port Wiring”, below to make a cable for Remote port.
See “Configure Network Settings” to configure the network settings.
