LOGGING TAB
The JSD-‐60 includes extensive logging. The left side of the screen shows the GUI log. It shows
GUI activity, such as connections to JSD-‐60 units. The right side of the screen shows the Unit
Log for the specific JSD-‐60.
The JSD-‐60 holds a log of the last 15,000 events. Events include level changes, format changes,
remote connections by the GUI or other devices, etc. Press the Get Latest button to get the 100
most recent log entries. Press the Get All button to get the full log from the JSD-‐60.
The log shows the record number in the JSD-‐60 log, the UTC time of the event, the “JSD Time”
of the event, and the “GUI Time” of the event. The JSD-‐60 stores all log events in UTC time.
When the log events are displayed by the GUI, the time at the JSD-‐60 is calculated based on the
settings entered using the “Date & Time” button on the Global Tab. The GUI applies the time
zone offset for where the JSD-‐60 is located, determines if the daylight saving time is observed
where the JSD-‐60 is located, and whether daylight saving time is currently in effect. Based on
this data, the GUI calculates and displays the time of the event at the JSD-‐60. The name of the
time zone (PDT in the sample) is shown in the column header to help identify the time. The GUI
also does a similar calculation to display “GUI time” or local time for the computer running the
GUI application. That is the time the event occurred at the GUI location, which may be several
time zones away from where the JSD-‐60 is located. The log shows the source of the event
(internal, USB Port, front panel, TCP4, etc.). When a device connects to the JSD-‐60 over
Ethernet, the connection and the IP address are logged. Later actions can be tied to a specific
IP address by looking back through the log for the last connection to that TCP port. The JSD-‐60
supports 5 simultaneous TCP connections on TCP4 through TCP0.
Pressing the Save button saves the currently displayed log data as a tab delimited text file. This
file can be imported into a spreadsheet or viewed with a text editor.
