6. In the Default Gateway field, enter the Default Gateway Address, if applicable, of the network to which the RVON-

16 card is connected.

A Default Gateway is only required if the RVON-16 connections are between LANs.

Under Settings for Pass-Through Serial via Ethernet

7. In the Target IP Addr field, enter the Target IP Address of the device you want to connect to over Ethernet.

8. From the First Serial Baud Rate drop down list, select the baud rate at which the data is transmitted for the first serial

port.

NOTE: Configuration of the 2nd pass-through port via AZedit is not supported.

Under Settings for Connected Devices

NOTE: You MUST configure the channels settings on each end of a connection to ensure the same codec and packet size

are selected at each end. Remember, the RVON-16 card has more channels which can be configured.

9. From the RVON Channel drop down list, select the channel you want to use to communicate to another device across

the network.

10. In the Device IP Addr: field, enter the IP Address of the device to which you want to connect.

11. From the Device Type drop down list, select the type of device to which the RVON-16 card is connecting.

12. From the Device Channel drop down list, select the channel on the device to which the RVON-16 will communicate.

13. From the CODEC type drop down list, select the CODEC type you want to use for this channel.

14. From the Packet Size drop down list, select the size of each audio packet.

NOTE: A CODEC is an algorithm used to compress audio. There are 5 Codices supported by Telex: G.711 μs law,

G.711A, G.729AB, G.723 (5.3k), and G.723 (6.3k). The type of CODEC will dictate the quality of audio you hear

and the network bandwidth used. The packet size determines how much audio is carried across the network in

each transmitted packet. The CODEC type and packet size chosen will require different amounts of bandwidth

from the network see “Specifications” on page 4. As with the CODEC type, the packet size you choose for the

audio transfer will affect the audio you hear and the bandwidth you use over the network. The larger the audio

packet you choose to use, the lower the bandwidth used. However, the larger packet sized can result in a higher

delay and longer gaps if the packet is lost. On the other hand, smaller packet sizes result in larger bandwidth use,

but lower delays and smaller gaps if the packet is lost. The Intercom System Engineer and the Network

Administrator may want to work together in choosing the CODEC type and packet size suitable for the size of

the network, so degradation of the network resources does not happen.

15. Select Enable VAD (Voice Activity Detection), if you want to conserve bandwidth when the audio level is below a

given threshold.

NOTE: Voice activity detection saves network bandwidth by stopping the flow of audio packets when silence is

detected. VAD is similar to VOX.

At this point you may choose another channel to configure or choose another card to configure.

16. Once you are completely finished, click Apply.

Apply sends all of the changes to all the cards in the intercom, or click Cancel to discard all changes you have made.
