Safety Warnings
WARNING: This unit contains lethal AC voltages. Disconnect the unit
from the AC supply before removing the cover.
WARNING:
The lightning flash with an arrowhead inside of an equilateral triangle is intended to alert
the user to the presence of un-insulated “dangerous voltage” within the product’s
enclosure. The “dangerous voltage” may be of sufficient magnitude to constitute a risk of
electrical shock to people.
CAUTION:
The exclamation point inside of an equilateral triangle is intended to alert the user to the
presence of important operation and maintenance instructions in the user guide.

2General Description
The FTSU-100D is a high performance signal distribution amplifier designed for use with the Brandywine
model PTS Precision Time System.
The FTSU-100D is contained in a compact IU rack-mount chassis. The FTSU accepts two sets of inputs. An input set
comprises a 10 MHz reference frequency, a 1PPS signal and status inputs from the reference generator. The FTSU-
100D provides automatic changeover should one of the source inputs fail. Manual source select override is available
on the front panel. A variety of status indicators are located on the front panel for visual feedback.
The low phase noise frequency outputs are generated from a low phase noise oscillator that is phase-locked to the
reference frequency input. In the event of a reference input failure,the phase –locked oscillator will continue to
provide referenced frequency outputs with a stability of 3 x 10-9over temperature.

3Unpacking and Installation
3.1 Unpacking
Carefully remove the FTSU-100D from the shipping carton. The following items should be included in the
shipment: •1 FTSU-100D
•1 power cord
•1 user guide
Note the power entry module on the rear of the FTSU-100D chassis. Please take note of the voltage
displayed on the rear of the power entry module and verify that the voltage matches the local line’s voltage.
Insert the provided power cord into the rear of the power entry module and connect the power cord to an
AC power outlet.
CAUTION:
THE FTSU-100D WILL BE DAMAGED IF THE INCORRECT AC LINE SETTING IS USED.
WARNING:
REMOVE THE POWER CORD FROM THE FTSU-100D BEFORE
ADJUSTING THE LINE VOLTAGE.
If the AC line setting is incorrect, detach the power cord from the power entry module. Use a small
screwdriver to lift up the fuse cover on the power entry module to remove the fuse holder. Reverse the fuse
holder and re-insert the fuse holder, making sure that the correct AC line voltage is now displayed on the
rear panel.
3.2 Installation
The FTSU-100D may be bolted directly into a 19” rack mount enclosure or mounted by rack mount slides.
The FTSU-100D, when fully populated, has up to 30 cables attached to the rear panel, therefore it is
recommended that some appropriate cable strain-relief system be used to support these cables,
particularly when not using rack mount slides.

MANUAL P/N 900000106 REVA
11
If the rack mount slides (P/N 002000105) are used they must be attached to the FTSU-100D chassis with
10/32 screws.
CAUTION:
DO NOT USE SECURING SCREWS LONGER THAN 0.5”
BECAUSE THIS MAY RESULT IN INTERNAL DAMAGE TO THE FTSU-100D.
3.3 Connections
3.3.1 Power
Insert the power cord provided in the shipment into the rear power entry module (see 3.1). Connect the
input reference signals to the appropriate connectors on the rear panel.
CAUTION:
FOR CORRECT OPERATION, REFERENCE FREQUENCY A AND REFERENCE
FREQUENCY B MUST BE THE SAME FREQUENCY, WHICH IS TYPICALLY 10 MHz.
Connect the output cables to the desired output connectors. Any unused connectors may be left un-
terminated.
CAUTION:
DO NOT OVERTIGHTEN THE REAR MOUNT SMA CONNECTORS BECAUSE THIS MAY
RESULT IN DAMAGE TO THE FTSU-100D. THE CORRECT TORQUE TO USE IS 8 0Z-IN
3.3.2 Other Connections
Connect the output signals as required. For additional help connecting the output signals please refer to
Section 1.7.

4Getting 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.

MANUAL P/N 900000106 REVA

4.2.1 IPSetup.exe
To set up the network address using the IP Setup program, follow the steps given below. Note that IPSetup uses a
local broadcast on UDP port 20034.
1. Download the IP Setup program from the NetBurner website located at
http://www.netburner.com/support/public_downloads.html .
2. Double click on the IPSetup.exe icon and Figure 1will be displayed.
Figure 1NetBurner IPSetup Screen
3. Verify that the “Select a Unit” displays the current MAC and IP address of the FTSU-100Dunit connected
to the network.
4. Click on the FTSU-100D unit that needs to be configured. Note that the FTSU-100D unit is identified by
MOD5272.
5. Enter the network settings (IP, Network Mask, GateWay, and DNS).
6. To transfer the settings to the selected FTSU-100D unit, click the button.
7. Wait 15 seconds for the settings to be loaded into the FTSU-100D unit and for the FTSU-100D unit to
restart.
8. Verify that the FTSU-100D unit has the correct network settings and is connected to the network by
clicking the Search Again button.
9. To exit the IP Setup program, click the Close button.
10. Open a web browser, type the IP Address of the FTSU-100D unit in the Address bar, and press <Enter>.
For example, type 192.168.1.160 or http://192.168.1.160 and press <Enter>.
11. Figure 2will be displayed.
12. Configure the FTSU-100D unit. For more information on FTSU-100D configuration, refer to the
Configuration section of the user guide.
13. If unsure of which device –power off and on again to see which unit is removed from the list and
reappears with power on.
IMPORTANT INFORMATION: If the new network settings make the FTSU-100D unit inaccessible from
the setup computer, the IP Setup program won’t be able to locate the FTSU-100Dunit on the
network.
