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

© MOBATIME 11 / 24 800695.14
With IPv6, the ranges mentioned above are implemented as follows:
-IPv6: FF3y::EFC0:360x and FF3y::EFFB:220x, whereat x = 0x1..0xF and y=scope
E.g.: 239.192.54.5 FF38::EFC0:3605 or 239.251.34.10 FF38::EFFB:220A
For scope, the following values are possible: 2 = Link Local Scope
5 = Site Local Scope
8 = Organization Local Scope
14 = Global Scope
In contrast to the Unicast mode, the movement receives multicast addressed time and time zone
packets from a fixed server group address (multicast IP address). The standard port numbers are 123
(NTP) and 65534 (time zone). The Multicast operating mode signifies only a minimum amount of con-
figuration work for a network administrator. The server group address is selected with the switches 1.5
to 1.8. In addition switch 2.7 allows selection of two different address ranges. The following settings
are possible:
Switch 1: Switch 2: Group address Switch 1: Switch 2: Group address

4.3.3 Slave Mode
The Slave movement has no network connection. It is synchronized with local time and monitored by a
Master movement (operating mode Unicast or Multicast possible). The cascade can help to reduce
wiring effort since only one LAN connection is required. The disadvantage is that the slave movements
cannot be addressed directly via a network connection. Monitoring is only possible via Master move-
ment. Power supply in the cascade is only possible through the Master movement (with PoE or DC
power supply). See chapter 5.1.

5. Operation details
5.1 Power supply
The movement has a supply input for direct current +24 VDC. In addition, the NBU 190 can be pow-
ered by PoE (Power over Ethernet) from a switch. The variants of the power supply can be used indi-
vidually or in combination.
The power supply is internally connected to the plug for the cascade. Only one source (connected to
the master movement) is needed to power all movements of the cascade.

5.2 DHCP
If the movement operates in Unicast mode it automatically tries to obtain the network configuration
from a DHCP server within the network. The DHCP options will be evaluated automatically.
The accurate description can be found in the manual BE 800793 Description MOBATime Network
clocks.
The network administrator must configure the DHCP options accordingly.
5.3 IPv6
IPv6 allows for up to 4 parallel IP addresses, prioritized in decreasing order:
-address given by DHCPv6
-fix address
-address calculated with auto-config (SLAAC / RA)
-link local address
It is possible to deactivate DHCPv6 and / or auto-configuration.
Calculation of the link local address from the MAC address:
fe80::2[2nd part MAC]:[3rd part MAC]ff:fe[4th part MAC]:[5th part MAC][6th part MAC]
Example: MAC: 00:16:91:12:34:56
IPV6: fe80::216:91ff:fe12:3456
5.4 DHCPv6
In the unicast operating mode, the NPR tries to get the network configuration from a DHCPv6 server in
the IPv6 network. The DHCP options are automatically evaluated.
A detailed description can be found in the manual BE-800793 Description MOBATIME network clocks.
The network administrator is responsible for configuring the DHCP options accordingly.
5.5 Autokonfiguration / SLAAC
In the unicast operating mode, the NPR tries to calculate the network configuration from the infor-
mation of a router (RA) in the IPv6 network: IPv6 address.

A detailed description can be found in the manual BE-800793 Description MOBATIME network

5.6 SNMP
To allow an integration into a network management system, the NBU 190 supports SNMP version 2c.
The definition is specified MOBANetClock.MIB. The manual BE 800793 shows the possibilities and
use of SNMP.
5.7 Local time calculation
NTP movements are synchronized to UTC (Universal Time Coordinated). In order to calculate and
display the current local time the movements require additional information. This information is provid-
ed by a so called time zone entry (daylight saving time rule). The NBU 190 has a pre-defined table
with 64 entries. One of these entries can be selected using the switches 2.1 to 2.6 (Note: Switch 1.4
must be switched off to use the pre-defined table. See chapter 4.2).
The NBU 190 alternatively supports the calculation of local time based on the time zone entry provid-
ed by time zone server (switch 1.4 set to ON position). If the movement is operating in Unicast mode it
will request the entry from the configured NTP server. If it is operating in Multicast mode it will receive
the corresponding entry from the configured server group address (see chapter 4.3.2).
Only values 1 to 15 are valid settings. Otherwise the time zone is not defined.
Cascaded slave movements receive local time from the master movement. The switch settings are
ineffective.

5.8 Accuracy / synchronization loss
In synchronized state the deviation typically is lower +/-50 ms.
The movements continues running autonomously for 24 hours without synchronization with
quartz accuracy. After that the clock signalizes synchronization loss by setting the hands to 12:00 po-
sition and waiting for renewed synchronization. The deviation without synchronization after 24 h is
typically lower +/-2 s (quartz accuracy: 20 ppm at room temperatures). Slave movements totally con-
tinue running for 48 hours without synchronization (timeout master + timeout slave).
Note: The mentioned deviations depend on the accuracy and ability of the time source
(NTP server). NTP reception can be affected by network traffic and network devices
(hubs, switches, routers, firewalls, etc.).
5.9 Time source redundancy
The availability of the time source in the network can be enhanced by redundant installation of NTP
servers. Depending on the selected operation mode of the NBU 190 one of the following strategies is
recommended (also adequate for time zone servers):
5.9.1 NTP Client Unicast
Up to four different NTP server addresses can be provided to the NBU 190 by means of DHCP/
DHCPv6 or the PC tool MOBA-NMS. If three NTP requests stay unanswered by the current NTP
server the movement changes to the next server (if available). The duration until a change happens is
depending on the configured NTP request time interval (default: 3 x 10 seconds). After a reset the
movement sends the NTP requests to the first server.
5.9.2 NTP Client Multicast
Two NTP servers have to be installed sending out NTP packets on the same multicast address. The
sending intervals of the servers have to be chosen in a ratio that synchronization in normal operation
is done by the first server. Only in case of failure of the primary server the secondary server should
take over synchronization. The ratio of the number of transmitted packets between primary and sec-
ondary server should be about 4:1:
• Sending interval primary server: 1 packet / 1 minute
• Sending interval secondary server: 1 packet / 4 minutes
The selection of the server hence depends on the dominance of the server with the shorter sending
interval. If the primary server fails the secondary server thus becomes dominating.
5.10 MOBA-NMS (MOBATime Network Management System)
MOBA-NMS is a Java based PC program used for the configuration and status
requests of NTP movements. This software allows for a central configuration of
one or multiple devices.
Further informations, manuals and the software itself are available on our website
http://www.mobatime.com. These are also available on a USB stick (must be or-
dered separately).

6. Update
The firmware resp. the bootloader of a clock can be updated using MOBA-NMS. However, de-
pending on the reason for change the settings on the clock are lost. The protocol TFTP UDP
Port 69 is used.
In the multicast operating mode, an update is carried out sequentially on multiple clocks. In the
unicast operating mode, this is done parallel.
Attention:
For the update, a DHCP server in the network is required.
