4 Getting Started
4.1 Powering Up the FTSU-100D
Once all connections to the FTSU-100D have been made, apply power to the unit by setting the On/Off
switch to the on position. The On/Off switch is located on the front panel.
If an external reference is fitted, verify that the two green LED’s for Reference A Available and Reference B
Available are illuminated. This indicates that the FTSU-100D has detected the presence of the external
references.
Place the Reference Select Switch in the center (AUTO) position. The green Reference A ONLINE LED
and the AUTO LED should illuminate. This indicates that the FTSU-100D outputs will be phase-locked to
Reference A and if Reference A fails, it will be automatically switched to Reference B.
Place the Source Select Switch in the PLL position. This is the normal mode of operation for the FTSU-
100D and this indicates that the reference frequency output distribution amplifiers are fed from the output of
the internal Oven Controlled Crystal Oscillator. Verify that the PLL Available LED and the Reference
Available LED are illuminated.
Approximately 5 minutes after the power is applied, the PLL Locked LED should illuminate. The Holdover
and Fault LEDs should be extinguished. The FTSU-100D is now ready for operation.
4.2 Setting the Network Address
The FTSU-100D is shipped with a label that indicates the IP address stored in the unit. The default settings
are:
•
IP Address: 192.168.1.160
•
Subnet Mask: 255.255.255.0
•
Gateway: 0.0.0.0
To set the network address, the user may use either IPSetup.exe or a web browser. The two processes
are described below.
