Global Tab
Global settings, those that do not
change with format or EQ set,
are set or displayed here.
Unit Time
The time settings in the unit can
be observed in this section of the
tab. These settings are set using
the Date & Time button at the
top of the screen. 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.
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.
Sleep Settings
The JSD‐100 includes a sleep timer. The timer is reset to its timeout value on any format change, any fader level
change, or any audio output above ‐20dB (referenced to 300mV RMS). If, for example, the sleep timeout is set to 1
hour, the system will go to sleep 1 hour after the last format change, level change, or audio. When the system goes
to sleep, power consumption is decreased from about 18W to about 7.5W. The system wakes up on a format
change, a level change or a specific command over Ethernet (See Appendix B). Audio presence will not wake the
system up since the audio circuitry is shut down during sleep. The current sleep timer value is shown. The unit will
go to sleep in the displayed number of hours and minutes. To set the sleep timeout, key in the number of hours
and minutes or use the arrows to change the Sleep Timeout value. Once the value is entered, press Set Timeout to
save the value in the JSD‐100. If sleep is not to be used, check Disable Sleep Timer and press Set Timeout.
SNMP Community Settings
This section allows the Write and Read community settings to be viewed or changed. The JSD‐100 does not
currently use the write community setting since the JSD‐100 cannot be controlled over SNMP, only monitored.
Remote Fader Settings
This section allows the display timeout on remote volume controls 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.
Unit Status
This portion of the global tab shows the temperature within the JSD‐100, whether the optional DI‐80 and DI‐84
board are present, and the status of AES inputs. The DI‐80 board is required for 16 channel digital input. Without
it, the AES input is 8 channels. The DI‐84 board is required to decode Dolby Digital® from two channel inputs.
When the Get AES Status button is pressed, the AES Channel Status indicators are updated. Green indicates the
parameter is true. Red indicates it is false. Gray indicates it cannot be determined.
