Support - Frequently Asked Questions and Troubleshooting
Does this master clock convert time data to 2-wire 24-volt communication protocol?
No. To convert time data to the 2-wire 24-volt communication protocol, the user must purchase a
converter box by ordering part number SCB-100-000-1
My sync-wire secondary clocks do not seem to be getting the time shown on the master clock.
What went wrong?
Keep in mind that the clock 1 and clock 2 outputs control the sync-wire systems. Some Sync-Wire
systems may take up to 12 hours to fully synchronize. Check to be sure that the correct system has been
set for the appropriate clock circuit. Check the setting definitions under the section labeled Manual
Controls: Setting 20.
What communication protocols (inputs) can this master clock use to receive time data?
NTP, SNTP, 59 minute correction, four different versions of 58 minute correction, National Time/Rauland,
Dukane Digital, Rauland Digital, Once a Day Pulse, and an RS485 protocol.
If a GPS module and antenna was ordered with the master clock, it can receive time from GPS satellites.
What do I do if I cannot connect to the master clock web interface?
First, make sure that you are using the master clock’s current IP address. To view the master clock IP
address, press and release both the 1 and 9 buttons on the front panel simultaneously. This will cause the
the IP address to appear on the LCD display.
If the IP address is correct, contact your network administrator and ask them to confirm that there are no
provisions in your network firewall that prevent you from accessing the master clock. Firewall Ports 80,
123, and 1777 must be open to use the master clock on a network.
If all else fails, connect to the master clock with a cross-over cable.
What web browser should be used for accessing the Web Interface?
The Web interface has been found to function on Internet Explorer, Mozilla Firefox, Safari, Opera, and
Chrome. It is accessible on desktop and mobile computers, as long as the device is on the same network as
the master clock.
Can I connect to the web interface through a cross-over cable?
Yes. The NTP Master Clock can be accessed with a cross-over cable or over a LAN connection.
