2. Introduction
Wall LED clock is an industrial class product. It is synchronized via LAN to remote NTP/SNTP Time Server using Network Time Protocol. In addition to displaying TIME, clock can display DATE and TEMPERATURE from the external
sensor (extra option). Setting the clocks can be made with the use of buttons or
computer www interface via Ethernet TCP/IP.
3. User safety
Prior to turning the power supply unit on, please read the user
safety information.
General User Safety Conditions.
• The clock must be situated in a safe and stable place, whereas the network
cable should be arranged so as not to be subjected to trampling or pulling
out of the electrical socket by people or animals moving around the room.
• Internal clocks must not get wet. They must not be placed on a wet surface or used in wet conditions. Do not place any containers with liquids
on the device: vases, glasses, cans, etc.
• Do not place any naked flame sources on the device: candles, oil lamps,
etc.
• If you notice any damage to the cable or plug, you must immediately go to
a service in order to repair the fault.
Service
If necessary, take the unit to a specialist service. The device has no user-repairable
or useful elements.

PRIOR TO TURNING ON
•
•
•
•
Before you start, check the compatibility of supply voltage with the information on the device or power unit.
Always hold the socket, not the cord, while plugging in/unplugging.
If anything falls or pours inside the device or power unit, immediately remove the plug from the socket. Neither the device nor power unit, may be
used until an inspection is made by a specialist service.
Do not dissemble the device or power unit. Interior high voltage may
cause a fatal electric shock. Any repairs and adjustments should be made
only by qualified service personnel.
LOCATION
• Place the power supply unit in a well ventilated area and free airflow. This
will prevent overheating of internal components.
• Never place the device or power supply unit close to heating devices.
• Do not place heavy objects on the device.
CONDENSATION
In certain circumstances (e.g. a sudden change of location from warm to cold), the
device and/or power supply unit can become covered by steam, which temporarily
prevents the device from being used. When this happens, wait about 2 hours till the
temperature stabilizes and the moisture evaporates.
4. Assembly notes
Clock has two handles to hang them on a wall or suspend on chains. Do not fasten
the clock in a manner that causes stresses in the clock housing. Do not fasten the
clock using one side only.
If the clock is to be fixed using one side only, it must be specified in an order form.
Only then, a special housing for the clock will be made. Do not use other screws
from different housings or make additional holes, especially in external versions.
Installation of clocks should be made by an authorized person who has appropriate
certificates, depending on the scope of necessary work (electrical, elevation, etc.)

5. LAN (Ethernet)
Clock are available with an Ethernet (TCP/IP) interface. They can be included in
the local LAN network and controlled from any computer in the local network on
which the clock software has been installed. They can be controlled even from
distant locations (e.g. different cities, countries or continents) via the Internet. They
use the NTP time server for synchronization.

6. Relay control
Each clock comes with a control relay, which has one pair of contacts (normally
opened) connected to the relay coupling on the housing of the clock.
Relay coupling:
Relay contact-carrying capacity is 2A 250V AC and it needs to be used in a control
circuit (it should control a contactor or a sufficiently large actuation relay), and not
in an actuation circuit.

7. Configuring clock (SETUP)
7.1 Factory defaults
All clocks' addresses are factory-set to:
IP
192.168.123.5
MASK
255.255.255.0
GETEWAY *** not important ***
And this address appears by default while inputting parameters of a new clock.
7.2 Setting IP address
We do recommend to temporary change your IP using manual settings to:
PC
192.168.123.x (x≠5) MASK
255.255.255.0
GETEWAY *** not important ***
Please be sure your PC’s IP address belongs to same class of IP.
7.2 Lunching software setup
To start installation please extract CLOCK.ZIP to any local target folder, or
simply copy binary all \CLOCK subdirectory to your local HD. For Microsoft
Windows execute CLOCKCFG.EXE (note: other OS are not supported).
Following screen appears on display.
6
Type local symbolic name of NTP time server you want to use. This name does not
need to correspond to real name of remote server:
7
Once you start type NTP_SERVER_NAME, other default parameters appear too.
Save your data clicking “SAVE” button.
If IP setting is correct you will be able to read and display CLOCK parameters via
network by clicking “SERVICE” tab, and “READ” button. If reading error
reported please go back IP setting, otherwise firmware data is displayed.

7.3 Remote NTP Server
Configuring clock the IP settings is using special logical sub-network configuration:
IP
192.168.123.5 //clock IP
IP
192.168.123.2 //your PC - example
MASK
255.255.255.0
GETEWAY *** not important ***
Configuring remote source of time you need to remember that it will be outside of
above subnet. Below screen shows how to configure remote NTP server with IP
address 212.244.36.227 accessible from network class (clock will be switch to this
subnet in next step) mask 255.255.252.0 gateway 192.168.1.1
Once NTP server IP is ready to store please click “Program” button. At this step
your LED clock still might not be able to communicate with NTP server. The last
but not least is necessary, to setup clock target IP that let it work in correct sub-net.
The NTP protocol always provides UTC time. Please take care for correct clock
setting if you want to provide and support a) daylight saving b) local time related
to time zone you are located.

7.4 Setting or changing clock’s IP address
By factory defaults your clock is set to work with following subnet:
IP
MASK
192.168.123.5
255.255.255.0
//clock IP
You might like to change this address and let clock be visible in your final production subnet. Below screen shows how to change clock IP address to final target. In
our example, clock will be located at LAN with following configuration:
IP
192.168.1.123 //clock IP
NTP server 212.244.36.227 //public NTP server
MASK
255.255.252.0
GETEWAY 192.168.1.1
//router address
Once data is ready to store please click on “Program” button. Your clock IP will be
stored and changed.
IMPORTANT NOTE! You will be not able to communicate with clock with old
factory default IP. Please use new setting for future communication. You will be
able to restore factory defaults using hardware key sequence to reset product.

7.5 Adding more clocks to LAN
After connecting each clock to LAN it is necessary to change it’s final address for
the right one in order to address it in a local network (see section 7.4). After programming a new IP address in the clock new values of these parameters will automatically appear in IP address and TCP/IP port.
Note: You cannot include several new clocks in a network at the same time, as
there will be a conflict of IP addresses. Firstly, you must include the first clock,
program his target IP address, and then include the next clock, and program its IP
address (DIFFERENT from the previous one) and so on.
TCP/IP port – is a port to which the transmission is sent. By default its value is
1001. When choosing a port we must take into account firewalls installed both on
your computer, where the clock system has been installed, and in network devices
such as switches or routers. It is best to consult your local network administrator
and ask him if he allows traffic on the selected port.
[Confirmation transmission] - enabling this option causes the program await for
a reply confirming data collection after sending it to the clock. If no response
comes back, the system will send the data again. If after three attempts the system
does not receive any answer from the clock, then a message will be displayed
informing about the lack of communication with the clock.
8. Changing the battery
Clocks have a built-in battery lasting for about 3 years. After this period, power
failure can lead to a reset of the clock. Replace the battery in such an instance. For
this purpose, after the power is turned off, unscrew the housing side and remove
the front plate - the battery will be visible from the front of the clock. Place a new
battery type CR2032 inside.
The built-in backup battery exchange should be made by an electrician. In order to
ensure environment protection the old battery must be properly disposed of. It
should not be disposed of with household waste, but put in a special container. The
battery contains lithium.

9. Recycling
The product complies with EU directive 2002/96/EC
The crossed bin symbol on the device indicates that the product cannot be disposed
of with other household waste. After use, the product should be returned to an
electronic waste collection point or returned to the dealer. The user is responsible
for returning the device to an appropriate collection point or to the dealer.
Adequate waste segregation for later treatment, recovery or destruction helps
avoiding negative effects on the environment and health, and allows recovering
raw materials from which the product has been made. For detailed information on
available collection facilities, please contact the local cleaning service or the shop
where the product has been purchased.
