DV-IP User Manual
29
IP Address - If the IP Address is set to 0.0.0.0, the DV-IP will attempt to obtain an IP
Address, Subnet Mask & Gateway from a DHCP server (Dynamic Host Configuration Protocol).
The DV-IP name will be associated to this dynamic IP Address by the DNS server (Domain
Name Server). If the IP Address is set to 0.0.0.0 and no DV-IP name is specified, the DV-IP
will use the serial number as the URL. Alternatively click the DHCP "button" and this will set
the defaults for use with a DHCP server.
Subnet Mask - Specifies the Subnet Mask.
Gateway - This is usually the IP address of the router that provides connectivity outside of
the LAN. (Local Area Network). Setting the Gateway to 0.0.0.0 will provide connectivity only
within a LAN.
Primary & Secondary DNS - This allows you to specify the location of a Primary or
Secondary DNS server or Alternatively click the DHCP button and this will set the defaults for
use with a DHCP server.
DV-IP Name - The name used as a reference/URL by the DNS server when an IP address is
dynamically assigned by a DHCP server.
Base IP - The PPP IP Address used when the DV-IP dials on alarm or receives and dial in
connection (PPP_Link2) This PPP IP Address is independent of the main DV-IP IP Address.
DHCP IP - IP Address automatically assigned if the DHCP server is used.
DHCP Subnet - Subnet Mask automatically assigned if the DHCP server is used.
DHCP Gateway - Gateway automatically assigned if the DHCP server is used.
DHCP Name - Name defined in the DV-IP Name field plus any network extensions assigned
if the DHCP server is used.
Chassis Number - Serial Number of the DV-IP that is automatically assigned to an IP
address if the DHCP server is used.
NOTE - The following Bandwidth limitation controls seriously affect the
transmission operation of the DV-IP.
LAN, WAN, ISDN & PSTN - These buttons set the defaults for the maximum bandwidth
usage regardless of the amount of connections.
Maximum Transmit Rate - Controls the bandwidth used by the DV-IP over Ethernet or
PPP (Point to Point Protocol).
Transmit Image Buffers - Image buffers are used in order to improve the picture
delivery over Ethernet when used with slow connections i.e. 256Kb or less. Multiple
buffers allow the next image to be collected or read from disk while the current image is
being transmitted. Using a single image buffer improves the response to camera
selections over slow links e.g. PSTN.
Ethernet MTU (Maximum Transmit Unit) - Ethernet packet size. (Fixed at 1514
bytes).
Ethernet re-transmit timeout - Timeout controls the delay before a data packet is
retransmitted if there is no acknowledgement. Systems connecting to a WAN over
Ethernet will require an increased timeout to match the router. Please speak to the I.T.
Manager for this setting.
