48 RVON-C RTS Voice Over Network for Cronus
From the RVON-C drop down list, select the slot in which the RVON-C card resides, if it is not already selected.
3.
In the IP Address field, enter the IP Address you have assigned to the RVON-C card.
4.
In the Network Mask field, enter the Network Mask 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
6.
RVON-C card is connected.
A Default Gateway is only required if the RVON-C connections are between LANs.
Under Settings for Pass-Through Serial via Ethernet
In the Target IP Address field, enter the target IP Address of the device you want to connect to over Ethernet.
7.
From the Serial Baud Rate drop down list, select the baud rate at which the data is transmitted.
8.
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 selected at each end. Remember, the RVON-C card has different channels that can be configured.
In the RVON-C Channel drop down list, select the channel you want to use to communicate to another device across
9.
the network.
In the Device IP Address field, enter the IP Address of the device you want to connect to.
10.
From the Device Type drop down list, select the type of device the RVON-C card is connecting to.
11.
From the Device Channel drop down list, select the channel on the device the RVON-C card communicates to.
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.
14.
NOTE: A CODEC is an algorithm used to compress audio. There are five (5) Codices support by Bosch: G.711μs
law, G.711A law, G.729A, G.723 (5.3k) and G.723 (6.3k). The type of CODEC dictates 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 pack size chosen require different amounts of
bandwidth from the network (See "Specifications" on page 42.). As with CODEC type, the packet size you
choose for the audio transfer affects 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 hand, the 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.
Select Enable VAD, if you want to conserve bandwidth when the audio level is below a given threshold.
15.
NOTE: VAD (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.
Once you are completely finished, click Apply.
16.
Apply sends all of the changes to all the cards in the intercom, or click Cancel to discard all changes you made.
