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 as a risk of electrical shock
to people. Do not attempt to repair the unit without first unplugging it.
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. This unit
should only be repaired by qualified personnel. Several board assemblies contain static
sensitive devices. Appropriate procedures must be used when handling these board
assemblies.

1 Introduction
The Network Time Adapter (NTA-100) is used as a Network Time Protocol (NTP) client. When the
NTA-100 has been fully configured, the NTA-100 receives its time from the NTP Time Server and
distributes this time via the serial port to wall displays or other serial devices.

2.3 Connections
2.3.1 Power
Insert the power cord of the NTA-100 into an electrical socket to power up the unit. The Power LED
indicator will illuminate green.
2.3.2 Ethernet
Connect one end of an Ethernet cable to the NTA-100 Ethernet port. Connect the other end of the
Ethernet cable to a hub. Both the Link and Speed LED indicators will illuminate green.
2.3.3 Antenna
The NTA-100 can receive time from the GPS through the Antenna BNC connector. To receive time
from the GPS, connect the cable to the NTA-100 Antenna BNC connector.
2.3.4 Ethernet and Antenna Connections Example
2.3.5 Output
Connect the NTA-100 Output port to another serial device such as a display. The RJ-12 connector is
used for the Output port. The RJ-12 connector has two outputs, RS232 and RS422. RS232
transmits data using pin 2, whereas RS422 transmits data ‘A’ using pin 5 and transmits data ‘B’ using
pin 6. Furthermore, one RS232 receiver may be connected to the NTA-100, whereas up to ten
RS422 receivers may be connected (in parallel) to the NTA-100.

3.2 Installation
The NTA-100 is shipped with a label that indicates the IP address stored in the unit. The default
settings are:
•IP Address: 192.168.1.1
•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.

3.2.1 IPSetup.exe
To setup the network address using the IP Setup program, follow the steps given below. Please 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/downloads.html .
2. Double click on the IPSetup.exe icon and the NetBurner IPSetup screen will be displayed.
3. Verify that the “Select a Unit” displays the current MAC and IP address of the NTA-100
connected to the network.
4. Click on the NTA-100 that needs to be configured. Please note that the NTA-100 is
identified by SB72.
5. Enter the NDK Settings (IP, Network Mask, GateWay, and DNS).
6. To transfer the NDK Settings to the selected NTA-100, click the Set Æbutton.
7. Wait 15 seconds for the NDK Settings to be loaded into the NTA-100 and for the NTA-100
to restart.
8. Verify that the NTA-100 has the correct NDK 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 NTA-100 in the Address bar, and press
<Enter>. For example, type 192.168.1.1 or http://192.168.1.1 and press <Enter>.
11. The Setup screen will be displayed.
12. Configure the NTA-100. For more information on NTA-100 configuration, refer to the
Configuration section of the user guide.
