7.4 Data communications
The unit fully relies on Ethernet connections to the Core module devices which must be IEC61162-
450 compliant and the unit provides (audio) data within the VDRs specified (commissioned) IP-
range (refer to
7.5 Indicators
None.
7.6 Errors
If errors occur within the interface these will be indicated on the display of the Bridge Control Unit.
7.7 Configuration
The individual VHF channel IP-addresses must be set during commissioning time. Please refer to
VDR Configuration functions.
7.8 Operating instructions
After commissioning of the VDR system, this unit does not require (crew) operating instructions.
7.9 Testing VHF Radios procedure
To test the VHF audio, a short broadcast must be completed.
NOTE:
When broadcasting on VHF, ensure that no transmissions are made that could be
confused with anything other than a test transmission.
The voice test should be performed from another VHF radio (VHF2) so that you are now testing
the Rx signal recording of VHF1 and say the words “Test VHF1 Receive” followed by a voice
count from 1 to 5 (or 10) and reverse the count back to 1, finishing the transmission with words
“Test Out”.
To test the VHF recording is as follows:
1. Check the VHF wire connection to the VDR to ensure it is correct.
2. Transmit the voice test as described above. A normal voice procedure is to say the words:
“Test VHF1 Transmit”, Count from 1 to 10 and reverse the count back to 1, Finish the
transmission with words “Test Out”.
NOTE:
When transmitting, ensure that the VHF is switched to a channel that cannot be
confused with any local distress or working frequencies
3. Note test time.
