Network Viewer Port
By default, the port number of the digital recorder is 8234 for Network Viewing
Software. Ordinarily, it is not necessary to change the port number of the
machine unless there is either:
1. More than one unit on the LAN and you are using a broadband connection
with a single public IP address
2. A specific policy for controlling the port numbers on the network is in place.
If either of these are the case, then the port number can be changed using the
Network viewer port option.
Warning: Ensure the port number allocated within this option is unique for the
network and does not conflict with any other device on the network. If port
numbers conflict on a network it is likely that one or both of the units with that
port allocation will not operate. Get advice from the Network Administrator
before changing the port number.
Valid port numbers are between 0 and 1023 (Well known ports), 1024 and
49151 (Registered ports), and 49152 through 65535 (Dynamic and Private
ports).
When changing the Network viewer port number, the Remote Admin port
number will automatically be changed to 'Network viewer port number plus
one'. Therefore, if several machines are used on the same network, it may be
necessary to increment each machine's port number by 2 to allow full
operation. For example, port 6000 for unit 1, port 6002 for unit 2 etc.
Note: There is no indication as to the new port number on the digital recorder
itself, the port number is only revealed within this menu or when a unit is
detected on a LAN using the Network Viewing software.
If you are using a broadband connection, you will need to use the 'Port
Forwarding' or 'Virtual Server' function of the router to direct port traffic to the
correct IP address.

Advanced Settings

The Advanced Settings option allows the configuration of MTU and bandwidth
limitation.
MTU
The MTU (Maximum Transmission Unit) is the largest physical packet size,
measured in bytes, that a network can transmit. Any messages larger than the
MTU are divided into smaller packets before being sent.
Ideally, the MTU should be the same as the smallest MTU of all the networks
between your machine and the final destination. If the MTU figure is too large
packets will be broken up (fragmented), which slows down transmission
speeds, and in some cases cause a 'Connection to Unit Timed Out' message
when using DM Network Viewing Software.
MTU sizes can vary for each connection and it may be necessary to use trial
and error to find the optimal MTU, if you are unsure about the MTU size, use
the default setting (576) and work up if necessary. Typical MTU sizes are as
follows:
