2. Function description
The NBU 190 is a self-setting movement with hour, minute and second display. It is part of the family
of xBU 190 movements and supplements it as NTP synchronized / network capable variant. The
movement is suitable for indoor and outdoor slave clocks with dial diameters up to 800 mm. It is avail-
able for clocks with or without illumination.
Naming:
NBU 190(t) (S) 24/PoE
Options:
t Movement with long shafts for clocks with illumination
S Movement with second shaft
Note: This document describes the functions for all available movement types (refer to table in chap-
ter 1). Instructions concerning the operation of the second hand are only applicable for types with op-
tion S.
Features:
10/100 Mbit/s Ethernet LAN connection.
Power supply PoE (Power over Ethernet) and/or DC input. Allows supply redundancy.
Synchronization by a NTP server in the network.
Cascade of up to three slave movements (I2C bus). Synchronisation, power supply and supervi-
sion by the master movement. For double or four sided clocks only one LAN connection is re-
quired.
Operation mode selectable by means of 2 x 8 DIP switches.
Automatic takeover of the network configuration:
IPv4: from a DHCP server in the network: IP address, gateway address, subnet mask, up to 4
NTP server addresses, time zone server address, SNMP manager address.
IPv6: -SLAAC: IP address
-DHCPv6 server in the network: IP address, up to 4 NTP server addresses, time zone
server address, SNMP manager address
Alternatively: the network configuration can be set manually using the PC tool MOBA-NMS.
Alternatively use of a multicast IP address for synchronization / communication. Address se-
lectable by means of DIP switches for minimum configuration effort.
Alternatively use of SNMP V2c for configurations.
Automatic daylight saving time change according to a predefined daylight saving time rule (1 out of
64 rules selectable by means of DIP switches).
Alternatively automatic daylight saving time change according to a daylight saving time rule pro-
vided by a MOBATime time zone server in the network. (1 out of 15 rules selectable by means of
DIP switches).
Integration of the movement to a network management system (SNMP manager) supported: For
supervision, master movements can send out SNMP V2c alarm and periodic alive traps and re-
quest them with GET/SET.
Signalization of missing NTP synchronization after 24 hours by setting the hands to the 12:00 posi-
tion.
Different running modes of the second hand selectable by means of DIP-switches: Stepwise
(wobbling) or continuous. Revolution within 58 s with stop at 12:00 position or revolution within 60
s without stop.

3. Mounting guidelines
3.1 Mounting of movement series 190(t) (S)
The dial must be sufficiently stable. The fixing hole must have a
diameter of 12.3 mm. The movement must be fixed in vertical position.
Fig. 3 shows the positions of the mounting parts.
The disc nut (2*) M12 x 1 has to be tightened carefully with a special
wrench tool (Art. No.: 201998) and a torque wrench with a torque of (4.5
+/- 0.2) Nm.
Caution:
The ring nut (5), the compensation ring (6) and the spring washer (7)
must not be removed.
After tightening the disc nut (2*), the movement must not be wrenched!
3.2 Mounting of hands and starting-up
3.2.1 Mounting of hands
The shafts of the hour, minute and second hands are positioned ex-work on
the reference position (12 o’clock). The hands must be carefully fixed and
tightened on the shafts. Enough space must be provided between the hands.
See Fig. 4.
The position 12 o’clock must be checked for each movement after mounting
(see chapter 3.2.2).
3.2.2 Starting-up and check of the hand positions
Set DIP switch 1.1 to ON position (12:00 position, refer to chapter 4.2).
Either install a 24 VDC power supply and/or connect to PoE (Power over Ethernet). The clock runs
to the 12:00 position.
Are the hands exactly positioned at 12:00 position?
If any hand position is wrong the hands must be adjusted again (axis must not be moved).
Check the 12:00 position again (initialize procedure by interrupting the power supply or by
disconnecting PoE respectively).
If the hand position is OK continue with chapter 4 for further configuration.

4. Configuration
4.1 Overview
The NTP movement NBU 190 has three different operation modes:
Unicast
The movement works as NTP Client and as a master movement. It has an own IP address. See
chapter 4.3.1.
Multicast
The movement works as NTP Client and as a master movement. It joins a group address (mul-
ticast IP address). See chapter 4.3.2.
Slave Mode
The movement is working as a slave movement in the cascade and is controlled by a master
movement. The slave movement has no network connection. See chapter 4.3.3.
Configuration takes place via two DIP switch groups located on the housing side of the movement
(see chapter 4.2). The network configuration is automatically done by:
-IPv4: DHCP server (see chapter 5.2)
-IPv6: SLAAC or DHCPv6 Server (see chapter 5.3 and 5.5)
-manually using the PC tool MOBA-NMS (see chapter 5.10)
4.2 Switches
The movement has two switch groups (1 and 2). Each group contains 8 DIP switches.

4.2.1 Reset
Most changes of the configuration switches cause the movement to restart (software reset). It is there-
fore recommended to set the switches correctly prior to applying power.
Switches 1.1 to 1.3 and 2.1 to 2.6 do not trigger a reset. All other switch changes lead to a restart (de-
pending on the selected operation mode the movement needs to re-initialize).
If all switches are set to ON position for 10 seconds the movement executes a factory reset. All
configuration settings will be reset to default values.

4.3 Operation modes
4.3.1 Unicast
The movement has a network connection and is synchronized to UTC (Universal Time Coordinated)
from a NTP server. It is able to control up to three cascaded slave movements over the I2C bus (syn-
chronize, power and supervise).
This operating mode supports the monitoring and configuration of the movement via the network con-
nection. Network parameters can be automatically obtained from a DHCP server or can be manually
configured by means of the PC tool MOBA-NMS.
For supervision and configuration with MOBA-NMS one of the group addresses (multicast IP address-
es) 239.192.54.0 or 239.251.34.0 for IPv4 resp. FF38::EFC0:3600 or FF38::EFFB:2200 for IPv6 or the
IP address (selection with switch 2.7) is used.
The following switch settings select the operating mode Unicast (switches 1.5 to 1.8 and switch 2.8 in
OFF position):
Switch group 1:
ON
12345678 Switch group 2:
ON
12345678
In this operating mode the movement will attempt to obtain the following network parameters from a
DHCP server (see chapter 5.2):
-IP address
-Gateway address
-Subnet mask
-NTP server address(es) / Time zone server address
-SNMP manager address
In this operating mode, the clock will try to obtain the following network parameters in an IPv6 network
from a DHCPv6 server (see also chapter 7.4):
-IP address
-NTP server address(es) / time zone server address
-SNMP manager address
The NTP server addresses must be configured by the network administrator as DHCP options on the
DHCP server. If a server address was provided to the movement it will request time and time zone
packets (switch 1.4 in ON position) from this server. The request interval can be configured with the
PC tool MOBA-NMS.
4.3.2 Multicast
The movement has a network connection and is synchronized to UTC (Universal Time Coordinated)
from a NTP server. It is able to control up to three cascaded slave movements over the I2C bus (syn-
chronize, power and supervise).
Configuration can completely be done by means of the DIP switches on the movement (minimal con-
figuration effort). Further this mode supports monitoring of the movement via the network connection.
Single configuration parameters can be changed with MOBA-NMS via network.
For supervision and configuration with MOBA-NMS one of the group addresses (multicast IP address-
es) 239.192.54.0 or 239.251.34.0 is used (selection with switch 2.7). The group address is an IP ad-
dress in the multicast range (224.0.0.0 to 239.255.255.255), addresses selected by Moser-Baer AG
from a freely available range:
-IPv4: 239.192.54.x and 239.251.34.x, whereat x = 1..15
