indicate a problem with the phone line (the main display will indicate that a call attempt has
failed.)
Call Reference Time: The Call Reference Time determines when the next automatic call to
NIST will be placed. This parameter must be entered in UTC time. To disable automatic
calling, set all fields to zero.
Call Interval: The Call Interval determines how often the TYMSERVE will automatically call
NIST. The interval can be as short as 1 hour or as long as 1 year. When the Call Reference Time
is reached, the Call Interval time will be added to the Call Reference Time to determine when the
next call will take place. The more often a call to NIST occurs, the more accurate the time will
be. To disable automatic calling, set all fields to zero.
Call On Reset: If Call On Reset is enabled, then at reset when the Call Reference Time has
expired, a call will be placed immediately.
4.12 FEATURE PARAMETER DESCRIPTION (-ACTS)
This section describes the FEATURE parameters for the -ACTS version.
Set time manually: This feature allows you to set time manually.
The time must be set to UTC. Setting the time manually will overwrite the time set by NIST,
and any call to NIST will overwrite the time set manually.
Local Time UTC Offset: This feature allows you to set the UTC time offset for your local time
and does not affect the NTP timestamps, it only affects the display of time on the LCD display.
This parameter is specified as hours EAST of UTC (e.g. Pacific Standard Time PST is -8).
Daylight Saving Time: This feature works in conjunction with the Local Time UTC Offset to
provide a display of the correct local time in those areas where Daylight Saving Time is observed
(most of USA). This feature does not affect the NTP timestamps, it only affects the display of
time on the LCD display.
Modem Speaker Volume: This feature controls the volume of the modem speaker which is
turned on during the call's dialing and connect phases. The speaker is automatically turned off
once the connection to NIST is established.
Phone Prefix: This parameter sets the dialing prefix for NIST. The prefix may include any
dialing sequence that is required to reach an outside line, and also must include the NIST area
code (currently 303). The comma character provides a 2 second delay, use multiple commas if
necessary. The 'W' character instructs the TYMSERVE to wait for a dial tone.
NIST Phone Number: This parameter sets the 7-digit NIST phone number (no area code) and
is currently set to 494-4774 and should never require a change.
