1. Introduction
NTP (Network Time Protoc o l) is a highly-precise and convenient way to transfer time via the
network. NTP time source is available for free on the Internet, or can be bought for
independent use.
POE (Power Over Ethernet) utilizes the technology that delivers DC power to Ethernet
connected devices. POE enables data and power transfer simultaneou s ly through one
standard network cable, which makes the deployment of network equipment more
cost-effective.
GTD368 of GlobalTime brings together all the advantages of PoE technology and real-time
synchronized system to the market: get precise time source from the Internet, and receive
data and power over the same set of wires, which guarantees high precision and low cost.
Moreover, GTD368 double-sided display is available. With an extra screen( rather than an
extra GTD368 device), the double-sided display effect is achieved. This innovation facilitates
installation and reduces costs.

3. Installation
3.1 Packing List
Single-sided: One device of GTD368
Double-sided: One device of GTD368, one display screen, a set of pendant connector
3.2 Power Supply
1)If the local network supports P o E , One network cable is needed.
2) If not , power adapter is available.
3.3 Configuration Button
One red control button for you to realize following configuration:
A. Time format
In the state of time display, press the button for 3 seconds, the screen will display 12 or 24;
Loose the button and then press again, it will switch between 12 and 24. The configuration
will take effect in 5 seconds after loosing the button, and the screen will display time
accordingly.
B. Re-boot
P ress the button for 3 seconds, when screen display s 12 or 24 , press the button two times in a
row,
the clock will display E5, then the clock will reboot.
C. Time zone
In the same state, press the button for 6 seconds, the screen will display the present time zone .
One press one time zone added, till it reaches +14:00, then switch to -12:00 and mount t o UTC
time.

3.4 Installation Instructions of Double-sided clock
The detailed installation instructions are shown as below.
a. Remove the hole on the top of the single-sided clock.
b. Install the metal accessories, then make the network cable go through the hole. Meanwhile,
connect the multiple connector with another screen, as shown in the picture below.
Note:
(1) The GlobalTime digital clock can be powered by two ways . One is PoE while another is
adapter . You may select any one as you like. With P o E available, only one network cable is
needed. Otherwise, both the network cable and an adapter are necessary.
(2) When connecting the multiple connector with another screen, please pay attention to the
red line. It can not be put to the opposite direction.

c. There are three plastic hooks on the rear of the clock. Put the hooks into the corresponding
holes on the clock and close it.
d. After the installation being finished the double-sided clock will just like what is shown

Note: In case you would like to separate the screen and the single-sided clock, please use
special tools since the plastic hooks may not bear rough force. Any damage in that case is on
the user ' s account.
3.5 Wall Mounting
Only screws are needed. See the picture below:
There is 248 millimeters between the two hanging holes on the clock
rear.
The diameter of the
cantilever screw head should be within6-12 millimeters, and
the diameter of the screw stem less than 6 millimeters. Work will be done by hanging the
clock on the screws.
If the wall is newly decorated, please make sure that the cable required has been led out from
where the clock screen is to be installed; If not, we suggest leading in the cable through the
hole above the clock screen, and connect with the corresponding port.

3.6 Cantilever Mounting and Double-sided Display
The following steps are to be followed:
a. Remove the hole on the top of the single-sided clock.
b.Use the mental coupling of srew thread to fix the mental bracket on the top of the clock.
c. Make the cable go through the mental coupling to connect with the interface.
d. For double-sided display in this type, another display screen is needed.
Please observe the instruction in 3.4 (Watch the direction of the wire).
The following pictures are shown for reference.
3.7 Pendant Mounting and Double-sided Display
In this type, the following steps are to be followed:
a. Remove the hole on the top of the single-sided clock.
9
b.
Take
out the metal coupling and the nut at first, and install them on the top of the clock.
c. Then make the network cable pass through the pendant tube and the metal coupling;
connect the cable with the interior interface of the clock screen.
d. For double-sided display in this type, another display screen is needed.
Please observe the instruction in 3.4( Watch the direction of the wire)
