1. INTRODUCTION

The VP100/20 NET display is designed for displaying time and messages.
The time is displayed in the following format: day of the week, day of the month, month, hours,
minutes, and seconds. The messages can be displayed in the static, blinking or scrolling form. On
the display, up to 20 characters can be displayed simultaneously.

The display can be connected to a network through its Ethernet RJ-45 connector, through which the
programming of messages and the time synchronization with the NTP server are executed. The
messages are programmed on a personal computer which is connected to the network and on which
the Message Editor program is installed (the program is enclosed in the package).

2. MOUNTING AND CONNECTION OF VP100/20NET

2.1 Mounting

The regular, single-type display VP100/20 NET is adapted for the wall mounting. For this purpose,
two right-angled carriers, with screws and wall plugs are enclosed in the package. The double-type
display is designed for the ceiling mounting.

Fig. 2: Wall mounting, all dimensions in mm.

2.2 Connection and operation of the display

Connect VP100/20 NET to the mains. As it has no "power-on" switch, it will start functioning
immediately. You must also connect the device to the Ethernet network. The connector for the
Ethernet connection is installed at the rear of the enclosure. It is labeled “Network”. The time is
displayed following the introductory text. If after the device's last turning-off the internal memory­supporting battery has been discharged, all messages stored in the display will be deleted.

Immediately after the device has been switched on, a dot is displayed between the date and the
hour, which means that the display has not yet been synchronized with the NTP server's time. Using

VP100/20NET Page 5 of 25

the two keys at the display's rear or the Message Editor program, it is necessary to set the display's
IP address, the sub-network's mask, the default gateway and the NTP server's IP address on the
occasion of the first turning on. These settings are of vital importance for successful programming of
messages and for time synchronization via the network.

When the communication between the display and the NTP server has been established, the
display's internal clock will become synchronized, and the dot appearing between the date and the
time of the day will disappear.

If there is a DHCP server provided in the network, all of the settings can be managed by the server –
the DHCP client should be switched on in the menu (this is also the default setting). All the network
settings can be remotely controlled by Message Editor program (MED), which alone seeks for the all
displays connected to the local network. The message programming and time synchronization of the
display are not possible without prior proper network settings.

2.3 OUT connector, the connection diagrams

To the connector labeled OUT you can connect another VP100/20-type display (a version without a
network interface), provided it is set to a baud rate of 9600 and to the 8N1 data format. The
connection can be realized in two different ways:

 using RS232: for short distances (of up to 15 m);
 using 20-mA current loop: for longer distances between the two displays.

You can choose between these two connection alternatives by means of jumpers inside the display.

WARNING

Please make sure to unplug the device

before opening the enclosure!

In order to be able to manipulate the jumpers, it is necessary to open the enclosure: please unscrew
the four screws that hold the cover on its right side, pull out the cover, and pull out the plexiglas piece
and the small blocking plate. Unscrew the screws holding the displaying plates in their middle. Pull
out carefully the right displaying plate. Before pulling it out completely, you must unplug the flat cable
from its socket and interrupt pull apart the contacts of the power supply cable. As a result, the
jumpers on the microcontroller board become accessible. After setting them appropriately, close the
enclosure, proceeding in the reverse order.

2.4 Contacts of the relay

To the relay's connection terminals you can connect an external sound source, which will provide
sound accompaniment for the messages for which the "loud sound" option is checked. The figure
below shows the arrangement of the connection terminals.
