• 1.- Terminal with the following meaning depending on the MBS Unit Power option:
- AC MBS Units: Neutral contact (N).
- DC MBS Units: Negative contact (-).
• 2.- Terminal with the following meaning depending on the MBS Unit Power option:
- AC MBS Units: Line contact (L).
- DC MBS Units: Positive contact (+).
• 3.- Power supply Earth contact.
• 4.- Pressure equalizer.
• 5.- Chassis Earth contact.
• ETH: Connector that allows Ethernet connection between MBS Units. It also can be
used as Maintenance Ethernet connector.
• PoE/ETH: Power Over Ethernet (IEEE 802.3at) connector. It provides power supply
(48 VDC) and Ethernet connection to a PoE radio link. It can be used as
Maintenance Ethernet connector if there is not radio link (Poe) connected.
• PoE: Power Over Ethernet (IEEE 802.3at) connector. It provides power supply (48
VDC) and Ethernet connection to a PoE radio link.
• SYNC OUT: Synchronism output connector. It provides synchronism to a second
MBS Unit through its SYNC_IN connector.
• SYNC IN: Synchronism input connector.
• DIV OUT: Output reception connector. It provides the receiver chain 2 to the next
MBS Unit through its DIV IN connector.
• DIV IN: Reception antenna connector (receiver chain 2). It is connected to an
antenna or to a MBS Unit DIV OUT connector (diversity 2).
• ANT: Transmission/reception antenna power connector (receiver chain 1).
• POWER OUT: Output power supply connector. It provides power supply to another
MBS Unit with the same Power Supply option.
• POWER IN: Input power supply connector (VAC or VDC).
