Description
Server IP This is the REM current IP address. If the “Network” is set to “Automatic”,
this field cannot be changed. If the “Network” is set to “Manual” then this
field may be changed. The IP address is entered one octet at a time. The
default value for this field is 255.255.255.000.
Local Use Networks - If the Ethernet network is local, arbitrary numbers
can be selected for the IP Address. The IP Address consists of a group of
four numbers from 0 to 255, separated by periods, for example:
207.142.140.101. Do not duplicate numbers on the network.
Use on Networks Connected to the Internet - If the network connects to
the Internet, the network IP addresses must be obtained and registered
with American Registry for Internet Numbers (ARIN, http://www.arin.net).
When used on the Internet, the IP Address is used to specify hosts and
networks. Internet Protocol (IP) numbers are part of a global,
standardized scheme for identifying machines that are connected to the
Internet. A Network Administrator or System Engineer should be consulted
on these issues.
Server Host Port TCP port number used for host communications. A 4-digit value may be
entered from the numeric screen. The default value for this field is 2305
and should not be changed for most configurations.
Server Name Local domain name for the REM. All other devices on the network will
reference the REM by using this name when the “Network” is set to
“Automatic”. If more than one REM or STEM is used on a network, each
STEM must have a unique name. If not, only one REM or STEM will be
functional and allow connection by clients.
Server MAC Hardware Media Access Control (MAC) address. Each Ethernet device
has a unique 6-byte MAC address. This field is displayed but cannot be
changed.
Subnet Mask The Subnet Mask is used to identify the local network when accessing IP
address on the Ethernet network. If the “Network” is set to “Automatic” this
field cannot be changed.
If the “Network” is set to “Manual” this field may be changed. The mask
is entered one octet at a time. The default value for this field will be
255.255.255.000. For a Subnet Mask on a local network, use an
unused address such as 255.255.255.0.
A subnet mask is used with an IP address to subdivide a network into
smaller networks, allowing a greater number of nodes on a network with
a single IP address. The Subnet Mask is the part of the IP address used
to represent a sub network within a logical network. By using Subnet
Masks, network address space is available that would normally be
unavailable. Subnet Masks also ensure broadcasts are not sent to the
whole network unless intended.
The default Subnet Mask, 255.255.255.0, is recommended to reduce
network traffic. When Subnet Mask, 255.255.255.0 is used, the
broadcast range would be the local Subnet only as follows:
255.255.255.0 Subnet Mask
207.142.140.XXX IP Address with a broadcast range of XXX.
255.255.0.0 Subnet Mask
207.142.XXX.XXX IP Address with a broadcast range of XXX.XXX
Using the Subnet Mask, 255.255.255.0, improves network performance
by reducing broadcast traffic.
Router The router’s (default gateway) IP address. The router is used when
accessing devices outside of the local network. If the “Network” is set to
“Automatic” this field cannot be changed. If the “Network” is set to
“Manual” this field may be changed. The IP address is entered one octet
at a time. The default value for this field will be 255.255.255.000.
