5.5 Contacts
The CM Power modules also serves to provide an external CAUTION contact which must be
connected to a central CAUTION system, when present on the ship.
The following contacts are provided:
During normal operational mode of the VDR (without any CAUTIONs internal to the VDR) the
CAUTION relay is held energized (by the VDRs Central Processing Unit) and the CAUTION
contacts are closed.
If the VDR presents an error or (power) fails, the contacts will open to their default (NO). This
allows remote CAUTION (Bridge Alarm) management systems to register the VDR (internal!)
CAUTIONs.
The VDR CAUTION does not reflect any CAUTIONs external to the VDR itself (i.e. of sensors or
equipment connected thereto).
5.6 Data communications
The CM fully relies on Ethernet connections to the other (sensor) devices which must be
IEC61162-450 or IEC62388 compliant and provide data within the VDRs specified
(commissioned) IP-range (refer to
The CM has 8 x 10/100 TX PoE port and two 10/100/1000TX uplink ports, delivering 802.3af
compliant PoE @48V. The total power budget is 65W with max. 15.4W per port.
The CM has two gigabit Ethernet ports for larger uplink bandwidth one of which is to be connected
to the CM’s CPU module.
