5. Operation details
5.1 Power supply
The movement has a supply input for direct c24 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.
