0150-0193G 59 DVMRe Triplex
q Main Menu → Communications → Ethernet Settings
An ethernet connection can be used to connect to the unit from a
PC for the viewing of live or recorded images. Use this menu to
configure the Ethernet communications settings. Select from the
following:
Ethernet: Select Enable or Disable.
Hostname: The default Hostname is the unit’s serial number
without the dashes. The user should modify only when GnuDIP
is selected in the Name Service field.
DHCP: Select Enable or Disable. Enables dynamic IP addressing.
When DHCP is enabled, the IP address, Subnet Mask, Gateway,
and Server fields are dynamically addressed.
Name Service: Select from Disable, WINS or GnuDIP. Enabling
WINS registers the hostname and IP address within the current
Network. This ensures that you can connect to the Triplex by
hostname within the network. See the Note below for information
on configuring Dynamic DDS with GnuDIP.
DDNS Update Interval: Select the Dynamic Domain Name Server
interval. Select from Disable or from 1 to 1440 minutes.
IP Address / Subnet Mask / Gateway: Consult with a qualified Network Administrator or an MIS
professional to configure these settings if DHCP is not enabled.
Primary Name Server / Backup Name Server: The IP addresses of the Primary and Backup Name
Servers. Not required if DHCP is enabled.
Print Server: Enter the Print Servers IP address to enable the Print Image operation (Function and
Zoom).
TCP MTU Size: Select from Standard, 1400, and 1200. The MTU describes the maximum possible TCP
packet size. Standard (1500) is optimal for most ethernet network environments.
HTTP Port : Select the HTTP Port. Select from Port 0 to 65535. Shortcuts are available for port 80
(Camera 1 button) and 8080 (camera 2 button). Consult with a qualified Network Administrator or an MIS
professional to configure these settings.
In order to use Dynamic DNS with GnuDIP, the user has to configure following in the menus:
• Name Service must be set to GnuDIP (Ethernet Setting Menu).
• Primary Name Server must be set to the IP address of the GnuDIP server (Ethernet
Setting Menu).
• Hostname must be set to the required hostname format e.g. ge04.companyname.net.
For registration purposes, the string until the first dot is used as hostname (here: ge04),
the remainder is used as domain (here: companyname.net). The hostname is set via
the Ethernet Setting menu and is case sensitive.
• DDNS update interval must be set to a reasonable value (e.g. 2 minutes).
• The password for the DDNS server has to be set in the Passwords->DDNS password
menu. The password is 4 digits long (The Enter button can be used for the number 0).
When everything is configured correctly, the DVMRe will send periodically a Dynamic DNS
update message over TCP port 3495 to the Dynamic DNS server telling the server its
hostname. The DVMRe does not include its IP address in the message. Instead the Dynamic
DNS server extracts the IP address of the DVMRe via the Ethernet source IP address. This
guarantees that the correct IP address is used even when the DVMRe is behind a NAT router.
