18Network SettingsThis option is used to configure the unit for connection to an Ethernet networkor dial-up. A pop-up box for configuring the network settings is displayed withthe following items:System NameEach D4 on the network can be given a system name to help identification; theunit name is displayed in the Network Viewing software. A maximum of 30characters can be used for the system name. The default unit name is 'D4'.Tip: If you do not want the unit to automatically identify itself on a network, usea '#' symbol as the first character. You will still able to access the unit acrossthe network by typing in the IP address directly into the Network Viewingsoftware.MTUThe D4 has an additional option for setting the Maximum Transmission Unit(MTU). The MTU is the largest physical packet size, measured in bytes that anetwork can transmit. Any messages larger than the MTU are divided intosmaller packets before being sent. Ideally, the MTU should be the same as thesmallest MTU of all the networks between your machine and the finaldestination. If the MTU figure is too large packets will be broken up(fragmented), which slows down transmission speeds, and in some casescause a 'Connection to Unit Timed Out' message when using DM NetworkViewing Software.Network Settings System name D4MTUNetworkBandwidth limitTCP/IP addressSub net maskDefault gatewayPPP portModem initialisePPP address0576Enabled100%000.000.000.000255.255.000.000000.000.000.000Off^M^M^MAT&F1S0=1172.017.002.0020576 - 1500Disabled1 - 100%Serial 1User PasswordA password can be set to prohibit unauthorized access to the menu systems.The default setting is Off.To Set or Change the Menu Password:1.
