Welcome to buy our products.
NTP server can get the standard time by GPS way to realize the
synchronization of computers, servers and devices supporting NTP
standard in LAN. NTP server equipment has been widely used in
inspection, legislation, transportation, scientific research, schools
and other occasions.
Main parameters of the time server
check the problems found in usage through the manual.
1.Sketch of time sever installation
⑴ Rack mount installation schematic
⑵ Desktop installation sketch
*：antenna must be outdoor as open as possible.
2. Time server configuration
The factory default IP address:192.168.1.30,sub network mask：
255.255.255.0。 WEB administrative page admin： admin,code： admin.
Process of initial configuration：
⑴ alter the IP of your computer to that of the time server
⑵ insure your server can receive ping
⑶ import：http://192.168.1.30I in internet explor(IE for example），open administration page，and import admin
and code to login in.
In administration page you can achieve those ：IP
modification 、 code management、 restart 、 reset、 GPS configuration.
Multi-interface setup：
Multi-interface equipment can be configurated with 8 interfaces
at the most ， among which the first interface is main network
interface， and the others are Sub network interfaces。 Every interface
is physically isolated， so it can configure different IP. Every interface’s
factory IP is 192.168.1.30，the way to modify default IP is same as
that of main network interface.through main network interface you
can inquiry the current IP of sub network interfaces and reset it。
3. Check of operating status
⑴ TQ5519 desktop installation series
The three status lamps on front panel show running status :
Power light ： constant brightness stands for the normality of
external battery, extinguishment stands for the abnormality.
RUN light ： flash stands for normal operation ,on the contrary
that system failure.
NTP light ： flash stands for satellite time unlocked, constant
brightness for locked.
⑵ TQ5519 rock-mounted series
TQ5519 rock-mounted series is equipped with LED display by
which you can check running status.
LED displays in upper and lower rows，the upper display time,
information of GPS satellite.the lower switches from IP
information to date,time and capturing state.
State explanation ：
12：00：01： current standard time
G09：number of locked GPS satellite (TQ5519/G)。
GPS： locked time sources,whose possible value include GPS （GPS
system）、BDS（Beidou system）、GLS（GLONASS system）、CDM
（CDMA system for TQ5519/C only）、NTP(superior NTP server)、
N/A(unlocked).
capturing state:stands for the status of time
capturing .0:equipment failure.1 ： time information has been
captured but hasn’t been completely genlocked .3：time information
has been captured and completely genlocked . 192.168.001.030:
current IP address of time server .
4. NTP client configuration and time service
NTP server of TQ5509/TQ5519 series provide standard NTP
service externally.all hardware(server,workstation and hardware
wanting time ) supporting protocol of NTP 、 SNTP V3 V4 can
capture standard time through the NTP server ， hereafter are
set-up methods of NTP in common systems.
⑴ Microsoft Windows series
All Microsoft Windows series can be synchronized with NTP.
As following is the setup(Windows Server 2008 for example )：
Click “control panel” ->“time and date setting ”->“Internet
time ”->“setting change” ,tick“synchronize with Internet time
server”and import NTP time server IP in “server”
， then click
“OK ”
.
“Update Now”stands for updating the current time .
⑵ Linux
Linux can be synchronized with NTP with a ntpdate command
such as ntpdate 192.168.1.30 as well as configuring NTPD service.
For more information,please refer to corresponding manual of
LINUX .
⑶ other hardware supporting NTP protocol
Start synchronization in NTP configuration options. The IP of
NTP server should be the same as that of NTP time server. Port
number is 123 and communication protocol is UDP, if needed. At
last ,click SAVE.
5. Way to acquire stable and exact time
Server series (TQ5509/G、 TQ5519/GB、 TQ5519/G) acquire
standard time through satellite (GPS) :
As GPS IS far away from the earth and its signal is relatively
weak when it reaches the earth.So we suggest time antenna be
palced outdoor as open as possible such as roof and somewhere
out of windows.
Theoretically our system can acquire standard time by capturing
only one satellite，but for the safety of time we suggest 4 or more
satellites be captured by GPS.If 4 or more satellites can’t be
captured for a long time,the change of antenna is suggested.
The feeder of antenna will influence signal strength too.
Through the test it is found that feeder can reach 50M. If ii exceeds
50M,we suggest you install a signal-amplifier or change the install
location of server.
6. common fault and solution
⑴ Time client can’t be synchronized with NTP server
A: NTP server works regularly or not （ inquiring running
status）。
B:the network of time client and NTP server is regular or
not(ping check)。
C:the time on time client and NTP server differ drastically or
not （out of time safety,LINUX and WINDOWS can’t be synchronized if
time differs drastically，please make synchronization manually）.
D:Time function of time client is open or not （such as w32time
to windows）.
⑵ time synchronized is inaccurate
A:Make sure that NTP server has captured enough satellites
and locked satellites.
B:Timezone of time client is set right or not。
C:longer the uptime is,more accurate the locked time will be.
1. Overview
The TQ5500 Series NTP Time Server provides accurate time synchronization to computers,
servers, and network devices via the NTP protocol. It is suitable for LAN environments and
widely used in government, enterprise, transportation, education, and healthcare systems.
2. Antenna Installation
It is recommended to install the satellite timing antenna in the most open area possible, such
as on a rooftop or outside a window.
In theory, receiving signals from only one satellite is sufficient to obtain standard time.
However, to ensure time reliability and security, it is recommended to receive signals from at
least four satellites. If reception of four or more satellites cannot be maintained for a long
time, it is advised to change the antenna installation location.
The length of the antenna feeder cable will also affect satellite signal quality. The maximum
recommended feeder length is 50 meters. If the actual installation exceeds 50 meters, it is
recommended to add a signal amplifier or relocate the time server closer to the antenna.
The antenna head and base are shown as in the figure. Use expansion screws to secure the
base to a fixed surface, then screw the antenna head into the base.
3. Server Installation
1) 2) The device uses a 19-inch 1U rack-mount chassis.
Mount the unit into a standard 19-inch rack using the four front-panel mounting holes.
3) Connect:
a. Power cable
b. Network cable (Ethernet)
4. Power-On Check
1) Ensure all cables are firmly connected.
2) Power on the device.
3) Confirm that the antenna is receiving satellite signals and the network is connected.
