NCast Presentation Recorder Reference Manual
6.3.3. Netmask
The IP netmask in use for this LAN segment (e.g. 255.255.255.0).
6.3.4. Gateway
The numeric IP address of the gateway host on this LAN segment (e.g. www.xxx.yyy.1).
6.3.5. Primary DNS
The numeric IP address of the primary Domain Name Server (DNS) for this LAN segment (e.g.
www.xxx.yyy.10). Domain name servers translate symbolic domain names to numeric IP addresses.
Various processes within the Presentation Recorder may, on occasion, require contact with a valid name
server.
6.3.6. Secondary DNS
The numeric IP address of the secondary (or backup) Domain Name Server.
6.3.7. Ethernet Mode
Adjusts the hardware link level settings for the connection between the Presentation Recorder and its
network switch. Normally Auto-negotiation will be sufficient to establish the correct settings, but under
special circumstances the installer may wish to force the Ethernet hardware to assume a different
configuration. The link speed and full/half duplex settings are adjusted through use of the pulldown menu
tab.
6.3.8. USB Stick Network Settings
An alternative way to configure network parameters for the unit is to edit a special text file on a USB
memory stick and to insert that memory stick into any USB slot in the unit during power-on. The
operating software looks for the presence of a USB memory and searches for the presence of a specially
named file. If this file is found, the network parameters are read from the file, installed into unit and used
during the network boot process. Once the unit has booted, the USB memory may be removed and is not
required again. The network settings from the file will be reflected as permanent entries shown on the
Network Configuration page.
The file on the USB stick must be named “ntwkconf.txt” and has the following lines of information:
dhcp=(bool)0
dns_1=(string)8.8.8.8
dns_2=(string)8.8.4.4
ethernet=(string)auto
gateway=(string)192.168.0.1
ipaddress=(string)192.168.0.2
netmask=(string)255.255.255.0
ntp=(bool)1
The “dhcp” keyword accepts two values: 0 which means disabled (no dhcp, use static addresses) or 1
which means enabled (use dhcp, dynamic addresses). The “dns” values identify the domain name
servers. The “ethernet” keyword accepts these link-level values: auto, 10fd, 10hd, 100fd, 100hd, 1000fd,
