IP Address Configuration

Overview

After physical installation of R/2 has been completed, at least one of the two network interfaces must be assigned an IP address to allow further configuration and normal operation.

IP Configuration

Each of the two network interfaces on R/2 can be assigned a static IP address, or obtain an IP address automatically via DHCP (Dynamic Host Configuration Protocol). In most applications, R/2 would be assigned static IP addresses, but it may also be helpful to use DHCP with reserved assignments tied to the MAC addresses of R/2. Contact your network administrator if you are unsure of what your network requires.

Metering Screen

After the unit boots, it should be displaying the audio input level metering screen. This is the normal “home” condition for the R/2 display. The up/down arrows will select between AES and Livewire input levels (see Chapter 7). “X” or the left/right arrows will allow you to return to this point from other areas of the front panel screens.

NIC Selection

From the metering screen, use the right arrow to move to the “Interfaces” screen. Select “NIC 1” or “NIC 2” by using the up/down arrow keys. The display arrow will move to indicate the current selection. Press the “” key to select the desired interface.

Network Mode

Once you have selected the desired interface (displayed here in the upper right hand corner of the LCD), you can select which mode that interface should operate in. By default, R/2 ships with both interfaces configured for DHCP.

Verify Current Interface Parameters

To verify the current IP address and mode, from the “Network Mode” screen, press the right arrow. In the example above, NIC 1 is set for DHCP and has an address of 192.168.123.154 with a subnet mask of 255.255.255.0 and a gateway of 192.168.123.253. Press the left arrow or “X” to return to the “Network Mode” screen.

Note: If the network cable is not connected to an interface, one of two conditions may occur…A “self-assigned” IP address of 169.x.x.x or all zeros (even if a static IP has been assigned). This may also occur if the unit is configured for DHCP but not able to reach a DHCP server.

Configuring a Static IP

From the “Network Mode” screen, press the “” key. You will be asked to switch to static mode. Note the interface number displayed in the upper-right hand corner (NIC 1 in this example).

Use the up arrow key to select “Yes”, then press the “” key. The “Static IP” configuration screen will be displayed.

To modify the static IP configuration:

Use the up/down arrow keys to select the field you want to change (IP address, Netmask, or Gateway).

Press the “” key to begin editing a field.

While editing a field, use the left/right arrow keys to select the digit you wish to change, then the up/down arrow keys to change the value.

When done editing, press the “” key.

When finished entering all values, press the right arrow key. The display will prompt: “Apply Changes?”

Use the up arrow key to select Yes, then press the “” key to select. After a few moments, you will be returned to the “Network Mode” screen.

To configure the second NIC, return to the “Interfaces” screen, select “NIC 2”, and repeat the configuration process.
