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.

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.

Please note that the unit will automatically reboot when a serious error or lock up occurs. This allows
the unit to reset and run instead of locking up.
4.1 Setup
The Setup tab consists of two sections, the System and IP Address. This tab allows you to modify
setup information for the Network Time Adapter. Please note that the Class C Network is being used
therefore valid IP addresses are between 192.0.0.0 to 223.255.255.0. To save all modifications
made to the Setup screen, click the Submit button. To undo all modifications made to the Setup
screen, click the Reset button.
4.1.1 System
The System section consists of two fields, the Version and Unit Location. The Version refers to the
version number of the firmware. The Unit Location refers to the location of the unit. A maximum of
127 characters may be entered in the Unit Location field. Entering apostrophes (‘) in the Unit
Location field is not recommended.

4.1.2 IP Address
The IP Address section consists of two radio buttons, the DHCP Enable and DHCP Disable and
three fields, the Device IP Address, Device Subnet Mask, and Device Gateway. If the DHCP Enable
radio button is selected, the NTA-100 will retrieve its configurations from the DHCP server. If the
DHCP Disable radio button is selected, the user must manually enter the configurations for the
device.
The Device IP Address is a 32-bit number that identifies the device on an IP network. The Device
Subnet Mask is a 32-bit number that enables the user to define sub-networks. The Device Gateway
is a 32-bit number used as the point of entrance from one network to another.
The default Device IP Address is 192.168.1.1, the default Device Subnet Mask is 255.255.255.0, and
the default Device Gateway is 0.0.0.0.

4.2.3 Daylight Saving Time
The Daylight Saving Time consists of the “automatically adjust clock for daylight saving changes”
check box. If the user clicks the check box, the system will automatically adjust the time of the
Network Time Adapter when daylight saving time occurs. If the user does not click on the check box,
the system will not automatically adjust the time of the Network Time Adapter when daylight saving
time occurs.
4.2.4 Daylight Saving Time (Advanced)
The Daylight Saving Time (Advanced) consists of three fields, the Daylight saving offset (DSTO),
Daylight saving start, and Daylight saving stop. The Daylight saving offset is a number that is added
to or subtracted from the time zone setting. The Daylight saving offset entered by the user may be
either in hours or minutes.
The Daylight saving start allows the user to add the daylight saving offset to the time the daylight
saving should start. The user must enter the daylight saving start time, the occurrence of the specific
day, the day of the week, and the month that the daylight saving should start. Note that the 24 hour
standard is used (e.g. 1:00 p.m. will be written as 13:00). For example, Pacific Standard Time adds
an hour at 02:00 on the first Sunday of April.
The Daylight saving stop allows the user to subtract the daylight saving offset from the time the
daylight saving should stop. The user must enter the daylight saving stop time, the occurrence of the
specific day, the day of the week, and the month that the daylight saving should stop. Note that the
24 hour standard is used (e.g. 1:00 p.m. will be written as 13:00). For example, Pacific Standard
Time subtracts an hour at 02:00 on the last Sunday of October.
Please note that the daylight saving start time and daylight saving stop time must be in 24 hour
format. For example, if daylight saving start time and daylight saving stop time are at 1:00 pm, the
user must enter 13:00.

4.4.1 Reference
The Reference consists of two fields, the Select reference and Reference Stable. The Select
reference allows the user to select one of the three references to acquire time from. The three
references used by the system are NTP Time Server, Serial Port Input, and GPS (model NTA-
100GM only).
The NTP Time Server reference uses the Network Time Protocol to synchronize the internal clocks of
a computer to the reference’s time. The stratum level may vary depending on the current reference
setting. To use this reference the NTP Server Address Pool must be setup.
The Serial Port Input reference continuously receives an update every second. The stratum level for
this reference is 2.
The serial time format is [STS][DOW][%x20][DAY]/[MONTH]/[YEAR][%x20%x20][HOUR]:[MINUTE]:[SECOND][0x0D] . The
table below lists the data and descriptions used.
