3 General information – Introduction
3.1 Scope of delivery
Please check your delivery for completeness and notify your supplier within 14 days
upon receipt of the shipment, if it is incomplete.
The package you received contains:
1 x NMI – Network MOBALine Interface
2 x 2-pole plug
3.2 Device description in this manual
This instruction manual is for the Network MOBALine Interface. Below, it will be re-
ferred to as NMI or interface for improved readability.
3.3 Function description
The NMI is a device which works as an interface between NTP (Ethernet) and
MOBALine. For this purpose, the NMI evaluates NTP packages and generates a
MOBALine signal for up to 12 slave clocks out of the received time information.
The NMI does not possess a configuration switch. The configuration takes place exclu-
sively over MOBA-NMS (not included in delivery) or alternatively via SNMP or using
DHCP parameters.
Using the NMI, MOBALine slave clocks (TREND only) can be completely monitored for
the first time. The TREND clocks can report their correct functionality back to the NMI.
The state of monitored clocks can be checked with MOBA-NMS.
The power supply is carried out via PoE (Power over Ethernet). The NMI reports to the
switch as a class 2 device.
In addition, the NMI possesses a passive current loop interface. This can be used for
synchronizing a slave clock (e.g. ETC) using NTP.

4 Configuration, displays and connections
4.1 Configuration
The NMI can be fully controlled and configured with MOBA-NMS. In addition, it is pos-
sible to give out parameters through DHCP or SNMP.
More detailed information about the configuration with MOBA-NMS, DHCP and SNMP
can be found in the document BE-800793.
4.2 Reset push-button
The NMI possesses a reset push-button between the two 2-pole clamps. To restart the
NMI (software reset), the push-button must be pressed for at least 4 seconds.
If the push-button is pressed for more than 20 seconds, the factory settings are loaded
(see chapter 9 Factory settings).
4.3 Connections and displays
The interface features the following connections and displays:

4.4 Operation modes / synchronization
For time synchronization, two operation modes are available, unicast or multicast.
4.4.1 Unicast
The interface is synchronized from an NTP server to UTC (coordinated world time).
This operation mode supports the monitoring and configuration of the NMI via the net-
work connection. The configuration can take place automatically through a DHCP
server or manually using the software MOBA-NMS.
For monitoring and configuration with MOBA-NMS, one of the group addresses (mul-
ticast IP) 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 is used.
In this operation mode, the interface will try to obtain the following network parameters
from a DHCP server (see also chapter 7.2):
-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 as a DHCP option by the network ad-
ministrator. If an address is sent to the NMI, the latter will request NTP and time zone
packages from the former. The request interval can be configured using the software
MOBA-NMS.
4.4.2 Multicast
The interface is synchronized to UTC (coordinated world time) by an NTP server. The
configuration can only be carried out using the software MOBA-NMS.
For monitoring and configuration with MOBA-NMS, one of the multicast group ad-
dresses (multicast IP) is used. The group address is an IP address 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
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
Contrary to unicast mode, the interface receives multicast addressed NTP and time
zone packages from an NTP server on a fixed group address (multicast IP). The
standard port numbers are 123 (NTP) and 65534 (time zone). The operation mode
multicast poses the smallest configuration effort for a network administrator.

4.5 Time signal outputs
The NMI is equipped with two time signal outputs: MOBALine and DCF current loop.
4.5.1 MOBALine
BA
• frequency modulated MOBALine time signal for self-setting slave clocks.
(TREND, SEM40/SAM40, SAM 00)
• output format: local time
• electrical properties: 20V / 50Hz
4.5.2 DCF 77 current loop
-+
• synthetic DCF time signal for synchronizing sub-master clocks (e.g. ETC).
• output format: local time
• electrical properties: passive current loop output
opto-coupler:
U
max=30V, Ion=10..15mA, Ioff=2mA @ 20V.
5 Monitoring TREND clocks
Using an NMI and MOBA-NMS, up to max. 12 TREND clocks can be monitored. Detailed in-
structions for configuration and monitoring can be found in the TREND clock manual (BE-
800913).
6 Mounting and commissioning
In order to mount the NMI and to launch it for the first time, the following process can be used:
1. Mount NMI to desired spot
2. Connect Ethernet cable with PoE supply
3. Configure using MOBA-NMS
4. Connect MOBALine slave clocks to line input
5. Alternatively, connect DCF current loop, if a sub-master clock shall be synchronized
6. If desired, configure TREND clocks for monitoring (see chapter 5)
7. After a short period of time, the alarm LED (red) should go out and the sync LED (green)
should light up
Notice: The NMI must be synchronized before TREND clocks can be configured!
