FEC920: USER GUIDE

September 18
6.2.1 Interface
This area of configuration allows the user to set up an IP address for the instrument, either by typing one in
(Fixed), or automatically (DHCP), assuming a DHCP server is running.
Figure 59 Network Interface menu
MAC
Read only. Media Access Control. A unique address for each instrument, entered at the
factory.
Client Identifier
The client identifier is a unique id used by DHCP servers that implement option 61. Each
FEC920
product will have a unique ID built up from its MAC address. If the DHCP server
is configured to use option 61, then it will use this ID instead of the MAC address to assign
a dynamic IP address.
IP Type
If ‘Fixed’, the user needs to enter an IP address and Subnet Mask in the following fields,
and a Gateway address if required.
If ‘DHCP’ the subsequent fields become read only, with the entries automatically
generated by the DHCP server. When set to DHCP, it takes several seconds before the
IP address is obtained from the DHCP server.
IP Address
Read only if ‘IP Type’ = ‘DHCP’.
If ‘IP Type’ = ‘Fixed’, the user may enter an IP address (IPV4 dot notation). This would
normally be supplied by the user’s IT department, or from the Network supervisor.
Subnet Mask
Read only if ‘IP Type’ = ‘DHCP’.
If ‘IP Type’ = ‘Fixed’, this sets a range of IP addresses that can be accessed. Normally
supplied by the user’s IT department, or from the Network supervisor.
Gateway
Read only if ‘IP Type’ = ‘DHCP’.
If ‘IP Type’ = ‘Fixed’ this allows the user to enter a gateway address for use when the unit
is to communicate outside the local network. Normally supplied by the user’s IT
department, or from the Network supervisor.
SNTP Enable
Select ‘Yes’ to allow time synchronization from a Simple Network Time Protocol (SNTP)
server to be enabled. When enabled the instrument time is updated every 15 minutes.
SNTP always works using UTC/GMT. Time zones are handled separately.
SNTP is a protocol that allows clients on a TCP/IP network to synchronize the instrument
clock with that of a server - port number 123.
FEC920
can act only as a client.
Servers such as Microsoft ‘TimeServ’ cannot be used with the
FEC920
because they are
not SNTP servers.
The SNTP client used in
FEC920
will not support stratum 15 server.
SNTP Server
The IP address of the SNTP Server. This only appears if the SNTP server is enabled.
If ‘IP Type’ is set to ‘DHCP’, the SNTP Server address is automatically assigned. Although
this address can be altered it will be overwritten once the instrument is power cycled. The
SNTP address should only be entered manually if ‘IP Type’ is set to ‘Fixed’.
For a description of SNTP alarms see Section 5.2.2.
