Model 2314/2316 SNMP Alarm Encoder
Fial Incorporated

The default IP address for every SNMP Alarm Encoder is 192.168.1.200. At a minimum, you
must change the last three digits of the IP Address for all subsequent boxes. (Example:
192.168.1.201).
NOTE: Do not Save & Reboot after changing the IP address, Netmask or Gateway, until you
have made all other changes and verified them. Doing otherwise may render the device
inaccessible to you as a result of an IP settings change.
Recommended: Make all changes desired on the various web pages, then a single Save &
Reboot.
Gateway: Enter the gateway IP address for this device. Packets will be sent to the gateway if the
destination IP address does not match the IP address range (zone) for the device. The
gateway is usually a router that sends IP packets to their proper destination. The entry is
checked for a properly formed value.
Netmask: Enter the netmask for the device. The IP address and netmask are closely linked, and
must be determined by an IP network administrator or someone familiar with the IP address
mappings for the sites on your local area network (LAN). See NOTE 2 below for additional
netmask information.
DNS Server (optional): Enter the IP address for a Domain Name Server (DNS) on your network.
The DNS entry is only required if you enter hostname.domain instead of IP address in an NTP
Time Server entry. If you are not using an NTP Time Server to set the SNMP Alarm Encoder
time then you can leave this field empty.
NTP Time Server 1 (optional): Enter the IP address (or hostname.domain) for an NTP or SNTP
(Simple Network Time Protocol) server on your network. The SNMP Alarm Encoder can
automatically synchronize its system clock with the time server using UDP port 123. If you
enter hostname.domain you must also enter an IP address in the DNS Server field just above.
That DNS must be able to resolve the hostname to the proper IP address.
If you do not use a time server, the Encoder time and date must be set manually, and the time
may drift up to plus/minus 2.5 seconds per day.
The Primary Domain Controllers in Windows 2000 domains act as SNTP servers. Any
Windows 2000 Server can be instructed to act as a time-server. Many UNIX/Linux systems
use the xntpd program to serve NTP and SNTP requests. Use a time-server with a GPS (or
better) clock if you wish to have very accurate SNMP timestamps; or, set your time-server to
synchronize itself with a free stratum-1 or stratum-2 time-server on the Internet. The SNTP
network traffic for the 2314/2316 is extremely low. The data in the UDP synchronizing packet
is only 48 bytes long, sent and received once every 3 hours.
NTP Time Server 2 (optional backup time server): Same as above. If two time-servers are
entered, the Encoder only uses the one that continues replying. If that one later fails to reply,
the Encoder starts using the other unit, toggling between time-servers after each failure. After
a successful time update, three hours will elapse until the next check. After a failed update,
