3.4 Radar scanner power connections
Radar scanner power requirements.
The digital radar system is intended for use on ships’ DC power
systems operating from 12 to 24 Volts DC.
• All power connections must be made via the VCM100 Voltage
Converter Module.
• The radar scanner must NOT be connected directly to a battery.
• The radar scanner must be connected directly to the VCM100
only.
• Only one radar scanner must be connected per VCM100 unit.
Each radar scanner in your system requires a dedicated VCM100
unit.
• The power connection between the radar scanner and the
VCM100 must be via an official Raymarine power and data digital
cable (purchased separately).
• Do NOT cut and re-join any part of the power and data digital
cable. A range of cable lengths and cable extensions is available
for longer cable runs.
• The radar scanner must be connected to the POWER OUT
terminals of the VCM100.
• The screen (drain) strands of the radar scanner’s power and data
digital cable must be connected to one of the VCM100 SCREEN
terminals.
The following diagram illustrates the power connections of the
power and data digital cable.
