Comm Settings
Press this button to configure the communications link to the JSD-100. The JSD-100 GUI can communicate
with the JSD-100 over Ethernet (TCP/IP), USB, or RS-232. Click on the appropriate tab for this unit. If you find
the GUI on occasion disconnects from the JSD-100, try clicking the Advanced button and increase each of the
timeout values. This may be required on a slow network.
TCP/IP
Check "Display automatically detected network devices" to get a list of JSD-100 units the GUI can find on the
network. Any device ever found is listed (they do not disappear if they have not been heard from in a while).
Select the appropriate unit from the list or click "Manual Add" to specify an IP address for a JSD-100. Use the
"Remove" button to remove a displayed unit from the list. Once the desired unit is selected, press OK to exit
the dialog.
USB
Select this tab to connect to the JSD-100 using USB. When the host computer is connected to the JSD-100
USB port, the JSD-100 should be listed under the device list. If the "Connect to first available USB device" is
checked, the first device (and probably the only device) on the list will be selected. If it is not checked, select
the appropriate device, and then click OK.
RS-232
Select the COM port the JSD-100 is connected to, and then click OK.
Unit Settings
This group of buttons handles a few “system wide” system configuration settings and backing up those settings.
Date and Time
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.
