Connection / Installation

Network Requirements

●

Ensure that there is sufficient network bandwidth for the data volume to be sent out by VN-C20.

● Data volume to be sent by VN-C20 varies

with the settings and number of distributions.

●

The maximum bit rate from VN-C20 is about 9 Mbps.

Estimation of total bit rate

The JPEG file size per frame varies with the encoding settings as well as input video signals. The following table may be used as a reference. When VFS is selected, the quantization table during JPEG encoding will be maintained and the file size will increase/decrease according to the input signals. When AFS is selected, encoding will be performed such that the target file size is the average size of multiple JPEG images.

Picture Quality Control Method

VFS (Variable

File Size)

AFS (Average File Size)

1 (High) 80 KB 27 KB

2 60 KB 20 KB

3 40 KB 13 KB

4 (Medium)

5 25 KB 8 KB

6 20 KB 7 KB

7 (Low) 15 KB 5 KB

VGA File Size

30 KB 10 KB

Selection may be made from the range between 10 to 100 KB

QVGA File Size

Selection may be made from the range between 3 to 33 KB

Insufficient network bandwidth

When there is insufficient bandwidth, the number of JPEG frames (frame rate) that the client can acquire will decrease.

Network Delay

When the client acquires JPEG via TCP, VN-C20 will send out data while checking the ACK from the client at the same time. For networks with considerable delay, data cannot be sent out until ACK is received, and therefore the frame rate will drop. Network delay due to a drop in frame rate can be eliminated by receiving data via multicast.

Network Jitter

When there is considerable network jitter, delay time may be prolonged and the image frame rate may drop.

Packet Loss

When acquiring images from VN-C20 via TCP, packet loss may be recovered by resending from TCP. When there is considerable delay during resending, however, missing data may occur and the image frame rate may drop. When packet loss occurs during multicast sending from VN-C20, the image frame rate may drop.

List of protocols and port numbers used by VN-C20

VN-C20 uses the protocols and port numbers listed below. Ensure that these ports are allowed through the firewall when a firewall is to be installed.

VN-C20 accepts requests from up to a maximum of 5 clients. In addition, it also allows transmission of 1 multicast stream. The total frame rate refers to the sum of these frame rates. For example, when 10 fps is requested by 2 clients, and in addition multicast is transmitted at a rate of 10 fps, the total frame rate will be:

10 + 10 + 10 = 30 fps

If the JPEG file size per frame is 30 KB, then the total bit rate will be:

30 KB ⳯ 30 fps = 900 KB/s = Approx. 7.2 Mbps

IP Address Settings

Setting IP address with the default VNC20 settings

There are 2 methods to set the IP address when VN-C20 is in its default settings.

(A) Assigning an IP address to VN-C20 from

the DHCP server

(B) Assigning a static IP address to VN-C20

䡵 (B) Assigning a static IP address

䢇 System configuration required for setting

IP address

VN-C20 is set to ADHCP EnableB(the DHCP client function is ON) by default. Upon starting up in LAN without DHCP server,VN-C20 starts running with the following IP address after time out of DHCP.

IP address : 192.168.0.2

Subnet mask : 255.255.255.0

Default gateway : None

䡵 (A) Assigning an IP address from the

DHCP server

● VN-C20 is set toADHCP EnableB (the DHCP

client function is ON) by default. To assign an IP address from DHCP server, connect VNC20 to LAN with DHCP server, and turn on VN-C20. Allowing the DHCP server to assign the same IP address to VN-C20 every time eases access toVN-C20.

● For details on IP addresses assigned to VN-

C20, please consult your network administrator.

● You can look up the IP address of VN-C20

using the search tool in the attached CDROM. For details, please refer to the AReadmeB file in the attached CD-ROM.

Caution:

● Set the DHCP server such that the IP

address assigned to MAC address of VNC20 from the DHCP server is the same each time.Connection may fail if the above setting is not performed.

Note:

● To set a static IP address for VN-C20,

connect VN-C20, switching hub and computer for setting using a straight LAN cable of Category 5 and above.

䢇 Set up the computer for setting the IP

address.

● Minimum computer specifications for setting

OS : Windows XP (Professional or

Home Edition) (SP2)

Web browser : Internet Explorer V6.0

Caution:

● When setting the IP address for VN-C20, do

so by using a network that is made up only of VN-C20, the computer for setting and the switching hub.

● Using a hub connected to other network

devices can cause problems.
