DS2 Network Guide
DHCP Gateway If the unit is to be installed in a DHCP network, this option would
display the gateway that was automatically allocated to the unit
from the DHCP Server.
DHCP Name This would be the name of the unit that is automatically allocated
by the DHCP server.
Serial Number This is a read only section and is generated by the unit hardware
identifying the serial number of the unit.
LAN, WAN, ISDN This option ensures the speed of the data from the unit matches
the speed of the network the data is being transmitted across.
These are default settings and are congured as:
LAN – 10000 Kilobits/second
WAN – 256 Kilobits/second
ISDN – 64 Kilobits/second
Force 10BaseT operation The unit supports 10 or 100BaseT half duplex transmission, this
will force the unit to operate at a 10BaseT connection.
Transmit Image Buffers This is used in order to improve the picture delivery over Ethernet
when using a slow connection, i.e. 256Kbps. Options available
are 1, 2 or 3 buffers.
Ethernet MTU This is the maximum transmit unit for the Ethernet packet. The
MTU is the largest physical packet size measured in bytes,
that the network can transmit. By default this gure is set to
1500bytes.
TCP Re-Transmit Timeout This is the time the unit will wait to re-send a packet if an
acknowledgement is not received.
When making a connection across a WAN link this gure should
be increased and should match the timeout gure for the router.
PPP Idle Line Timeout This is the time the unit will wait before dropping the PPP link if
data has not been transmitted or received.
PPP Link Down Timer If for any reason the PPP connection is lost then this is the time
period before the unit will be forced to drop the PPP connection.
PPP Persistent Prole This is GPRS / 3G type connection that the server will attempt to
connect again if the connection is lost. The named prole should
be in the etc\prole le.
Packet Size This is the maximum packet size that will be transmitted from the
unit. This gure is identied in Bytes.
Secondary Web Server Port If the default port setting for web serving has already been
allocated it is possible to congure a second port number.
eg. If the secondary web port is set for 8000 because the default
(80) web port is blocked by the network or rewall. To obtain
images from the unit enter the IP address plus the secondary
web port in the address section of Internet Explorer or in the
Viewer; http://172.16.1.2:8000 (<IP address><:><secondary port
number.>
How to Select and Enable Coaxial Telemetry
The unit supports numerous coaxial telemetry protocols allowing these cameras to be connected
directly to the unit and controlled using their native control protocol.
