Unit Time
The time settings in the unit can be observed in this section of the tab. The Unit Time data includes the current
UTC value in the JSD-100 real time clock, the time zone offset from UTC for standard time, the abbreviations for
standard and daylight saving time, and whether daylight saving time is observed at this location.
Set Time / Date Button
This button sets the time and time zone information in the JSD-100. The JSD-
100 itself only uses time of day in logging. Further, all log entries are made in
UTC. When viewed through the GUI, log data includes the time in UTC, the time
at the JSD-100 (JSD Time), and the time at the GUI (GUI Time). The use of these
three time zones allows for simple comparison of device logs, even when the
devices are in multiple time zones. The Date and Time dialog allows setting of
date and time data for the JSD-100. Since the JSD-100 uses UTC time, the
displayed time is UTC. If the system is using an NTP server, you do not need to
set the date and time. If no NTP server is available, set the date and time to the
current UTC time. The bottom portion of the dialog box deals with the date and
time at the JSD-100 itself. Set the Time Zone field to the offset from UTC for standard time in the time zone where
the JSD-100 is located. If daylight saving time (summer time) is observed at the JSD-100 location, check the
corresponding checkbox. Note that this checkbox indicates whether daylight saving time is ever observed at this
location, not whether it is currently in effect. For example, you would check the checkbox in California, but
uncheck it in Arizona. Fill the next two fields with the abbreviations for standard time and daylight saving time in
the time zone where the JSD-100 is located. The daylight saving time abbreviation will not be used if the daylight
saving time observed checkbox is unchecked, but you may want to fill it in anyway. Clicking OK transmits the data
to the JSD-100.

Network Time Protocol
This section also allows the IP address of the Network Time Protocol server to be set and enabled or disabled. If an
NTP server is available on the network, enter its IP address, check NTP Enable, and press the Set IP button.
Remote Fader Settings
This section allows the display timeout on remote volume controls JSDV-100 to be set. Use the slider to set the
number of seconds after an adjustment that the remote volume display will blank. Setting the timeout value to
zero prevents the display from blanking. See section 9 for more information on the JSDV-100.
