4. In the Network Mask field, enter the Network Mask of the network to which the RVON-C card is connected.

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

C card is connected.

A Default Gateway is only required if the RVON-C connections are between LANs or WANs.

Under Settings for Pass-Through Serial via Ethernet

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

7. From the Serial Baud Rate drop down list, select the baud rate at which the data is transmitted.

Under Settings for Connected Devices

NOTE: You MUST configure the channel settings on each end of a connection and ensure the same codec

and packet size are select at each end. Remember, the RVON-C card has different channels which

can be configured.

8. In the RVON-C Channel drop down list, select the channel you want to use to communicate to another device across

the network.

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

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

11. From the Device Channel drop down list, select the channel on the device to which the RVON-C card will

communicate.

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

13. 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.711μs law, G.711A law, G.729AB, G.723 (5.3k), 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 data is carried across the network in each transmitted packet. The CODEC type and

packet size chosen require different amounts of bandwidth from the network (See “Codec

Specifications” on page 75). 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 size can

result in a higher delay and longer gaps if the packet is lost. On the other had, 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 network

resources does not happen.

14. 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.

15. 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 make.
