Real-Time Clock
(Available only on the Base nested Utility page) – To set the date and time of the unit:
The user may enter a date using international format in the form DD/MM/YY (where DD
= day [01 to 31], MM = month [01 to 12], and YY = year [00 to 99]). Click [Set Date]
when done.
The user may enter a time using HH:MM:SS format (where HH = hour [00 to 23], MM =
minutes [00 to 59], and SS = seconds [00 to 59]). Click [Set Time] when done.
If the altered Date and Time settings have not been saved, the user may click [Refresh]
as needed to restore the existing stored date and time configurations.
Fine Adjustment of Internal Reference Clock
(Available only on the Base nested Utility page) – For fine adjustment of the Internal 10 MHz
reference oscillator, type in a value from –2048 up to +2047 into the Clock Adjustment text box.
Once the desired setting has been made in this section, click [Adjust Clock].
Firmware Image Selection
(Available only on the Base nested Utility page) – The user may specify the firmware boot
image in this section. Note the following:
Active Image (read-only): The currently-selected image is identified here.
Next Bootup Image: Use the drop-down menu to select Boot1 or Boot2.
Once the desired firmware image has been selected in this section, click [Set Image].
User Defined Circuit ID String
(Available only on the Base nested Utility page) – The user may enter a Circuit ID string of up
to 40 characters. Once the desired string had been entered in this section, click [Enter Circuit
ID] to save this change.
Modem Configuration
(Available only on the Base nested Utility page) – The user may save a modem configuration or
load a stored configuration using this sections. Note the following:
To Save a Modem Configuration: Use the Save Location drop-down menu to select a
storage location from 0 to 9 (the default is Don't Save) – note that any unused location is
noted as Empty (e.g., 3: Empty) – then click [Save/Load] to store the new configuration
into the unit's non-volatile memory.
If, however, a configuration has been previously stored to the chosen location, it will be
date-stamped (e.g., 3: 13:20:17 20/10/09 means that a configuration had been previously
saved to Location #3 on October 20, 2009 at 1:20:17 P.M.).
IMPORTANT
Saving a modem configuration to an already-stored location will cause
the unit to overwrite that location's information with the newly-saved
information.
