either a JSD‐100 or JSD‐80 configuration file under “file type.” If the JSD‐100 is replacing an existing JSD‐80,
use the JSD‐80 GUI to save the configuration file if it is not available on the computer you’re using. Then, with
the JSD‐100 GUI, open the JSD‐80 configuration file. Common data, such as equalization, will be loaded into
the JSD‐100.
 Save. The “Save” button prompts you for the filename under which the configuration data is to be saved.
Data can be restored to this or another unit using the Open button.
Communications
This group of buttons sets communications parameters between the GUI and the JSD‐100 and allows connections
to be set up and taken down.
 Connect. The GUI connects to the JSD‐100 specified in the Comm Settings dialog over the specified link.
 Disconnect. The GUI disconnects from the currently viewed JSD‐100. When the Disconnect button is pressed,
the GUI will ask if you want to save changes to the JSD‐100. When “Save Changes” is selected, the current
configuration will be saved to flash memory and will be reloaded the next time the JSD‐100 is powered up. If
“Save Changes” is not selected, the current configuration will not be saved or reloaded. Instead, the previous
configuration will be loaded on the next power up.
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
