6) The following configurations are done in the
System Settings
tab in the master clock:
6A)
*When installing a 2-Wire Clock System
the master clock is set to send RS485 time data to
the converter box once every second as standard. This time data rate sent from the master clock to the
converter box can be changed (if needed) by clicking on
System Settings
and changing the “Send
RS485” to another value.
6B)
*When installing an RS485 Clock System
the master clock is set to send RS485 time data directly
to the secondary clocks in the system once every second as standard. This time data rate sent from the
master clock to the secondary clocks can be changed (if needed) by clicking on
System Settings
and
changing the “Send RS485” to another value.
6C) *When installing a Wireless Repeater for a Wireless System, the wireless repeater (Not a Network
Repeater) can simply receive the time via a wireless signal transmitted from a master clock (that is
equipped with a transmitter or from a wireless secondary clock). Simply plug the wireless repeater to local
power (110VAC or 230VAC) and it will repeat the time signal as often as it receives it. A Wireless Repeater
can also obtain time data directly from a master clock through a pair of electrical wires that send the
RS485 time data. The master clock is set to send RS485 time data directly to the wireless repeater once
every second as standard. This time data rate sent from the master clock to the wireless repeater can be
changed (if needed) by clicking on
System Settings
and changing the “Send RS485” to another value.
6D)
GMT Time Offset
- The master clock is set to receive GMT (Greenwich Mean Time) also known
as UTC (Coordinated Universal TIme) from an NTP Server (standard) or from a GPS (optional). In order
to have the master clock send the correct local time to the secondary clocks in the system (at the
geographical location of where the clock system is installed), the GMT offset for your time zone must
be set. In order to do that you will need to know the correct GMT offset for your location, for example:
New York is -5 (hours offset from GMT), London is 0 (Hours) and Tokyo is +10 (Hours). This is done in the
System Settings
tab of the master clock web interface in the “GMT Offset” field.
6E) In some scenarios, there may be a need to adjust the time displayed by the master clock. If your
application requires such an offset, enter a value (in seconds) into the
‘Bias seconds’
field of the needed
offset. Keep in mind that an offset that is greater than 3600 seconds (1 hour) can be more easily set by
adjusting the GMT offset field.
