GMT Difference Direction
sets whether you are east (AHEAD) or west (BEHIND) of GMT. For example, Pacific
time (GMT-8) is behind, and Tokyo time (GMT +9) is ahead. Default setting is BEHIND.
Enable Time Protocol
toggles between OFF, SIMPLE, and NTP. Default setting is OFF.
•
SIMPLE - When network time is set to SIMPLE the unit attempts to contact the configured time
servers (see Time Servers setting below) periodically, attempting to query each using Simple Network
Time Protocol (SNTP), Time, and Daytime protocols, in that order. Once a response is received for
any protocol, the unit sets the system clock to the new time, updates the real time hardware clock
(RTC), then the network time process dies. The interval for checking network time is hard-coded to 12
hours plus or minus a random several hours.
•
NTP
-
When network time is set to Network Time Protocol (NTP), the NTP daemon is kept running at
all times. Unlike the SIMPLE setting, with NTP the clock is not immediately set as soon as a time
server is contacted. Rather, the NTP daemon utilizes various algorithms to set the time in an accurate
and robust manner. Since the NTP daemon updates the system time asynchronously, the current
time is stored in the RTC every 30 minutes while it is running. Note that if you change the clock
manually, it may be a period of an hour or more before NTP resets it.
Time Servers
displays a menu where the hostname or IP address of six time-servers can be configured. (Max
length 64 chars) The S530 uses the following servers by default:
•
time.nist.gov - 192.43.244.18 - Boulder, CO
•
time-b.nist.gov - 129.6.15.29 - Gaithersburg, MD
Event Log Settings
The Event Log is a record of all data events that occur within the S530.

List Events File
displays the contents of the Events File, if any records exist.
Clear Events File
purges the records within the Events File. Records in the Events File are deleted immediately
when this option is selected, so make sure you want to do this before selecting.
Enable Events Log File
is an ON/OFF toggle to enable Event logging. Default setting is ON.
Maximum File Size
sets the maximum number of KB the Event Log can reach before overwriting the oldest
records. Available options are 0, 32, 64, 128, 256, 512 and 1024. Default setting is 32.
Store Data Alarm Records
is an ON/OFF toggle to enable storing data alarm records. Default setting is OFF.
Store Sensor Events
is an ON/OFF toggle to enable storing records generated by environmental sensors.
Default setting is OFF.
Date/Time Stamp Data Alarm Records
is an ON/OFF toggle to prepend a Date/Time stamp to the beginning of
data alarm records. Default setting is ON.
Prepend Data Alarm Name
is an ON/OFF toggle to prepend the name of the Data Alarm to the beginning of the
data alarm record. This aids in identifying which Data Alarm an alarm record is associated with. Default setting is
ON.
