Double unitID
Use the 8L Double UnitID sub-menu item to define what the system should do with a double
unit ID.
Value
New UnitID*
Keep UnitID
Table 7.14 Double UnitID sub-menu values (* = default)
If "New UnitID" is selected, the microphone LED of the units with the same unit ID is switched
on and the user can assign a new ID by pressing the microphone button of the unit. When
"Keep UnitID" is selected, the microphone LED's starts blinking and button presses are
ignored. One of the units with the same unit ID has to be disconnected and optionally
replaced, to maintain the ID and solve the issue.
NOTICE!
For multi-CCU systems menu item 8L Double Unit ID needs to be set for each CCU, slave
CCUs do not follow the master CCU.
Menu item 8L Double Unit ID is not applicable for wireless units.
Unit/Hostname
Some networks are able to handle hostnames. In these networks the unique CCU hostnames
can be used as well. Use the 8M Unit/Hostname sub-menu item to set the name of the central
control unit. The unit name is also used as hostname in a TCP/IP network. The name of the
central control unit is maximum 16 characters and only consists characters allowed for
hostnames. Default the unit name is the text CCU plus the serial number.
After changing the hostname, the CCU needs to be rebooted (switched off) to make the new
hostname visible in the TCP/IP network.
NOTICE!
Because of hostnames conventions, a unit/hostname may contain only the ASCII letters 'a'
through 'z' and 'A' through 'Z' (on the network, the hostname will be treated case-insensitive)
and the digits '0' through '9'. No other symbols, punctuation characters or white space are
permitted. The hostname can be made shorter by clearing the last character one by one.
DCN-NG_IOM_V4.1 | V1.3 | 2012.07
d. In case one or more DCN control PCs are in another subnet, use menu 8Ic to give
each CCU the same TCP/IP default gateway 0.0.0.0 - 255.255.255.255. The default is
0.0.0.0.
Switch off all CCUs and connect the Ethernet and optical network cables. Now switch on
the CCU that is assigned as master and switch on all CCUs that are assigned as slaves.
All CCUs should run now without fault messages, see Table 8.1
