MultiView™ II XRTx Installation and User Guide 22
DC Power Connector
Magenta provides ready-to-use power supplies for MultiView™ II products. However, if there is a reason a
substitute power supply must be used, then the following information is important for maintaining product
reliability and performance:
Magenta AC/DC Power supply output rating: Regulated +5VDC @ 3Amps.
Power-input rating for MultiView™ II XRTx: 5VDC, 1.2Amps max.
The XRTx’s DC power input connector accepts an industry-standard coaxial-DC plug with the following
specifications:
• Coaxial power connector
• OD = 5.5mm
• ID = 2.5mm (accepted center-pin diameter)
• Length = 11mm (overall length of insertable plug end)
• Inner contact (pin-socket) = +5VDC
• Outer contact (sleeve) = Ground
It is highly recommended that the inner contact (center-pin contact) of any mating DC plug utilize a “tuning-fork”
shaped design, rather than a plain barrel shape. The tuning-fork design greatly increases the reliability of the
power connection. The plain barrel style connector can cause intermittent operation, often resulting in
“mysterious” system problems that are difficult to identify.
The Magenta-provided power supply already comes with the correct output ratings and DC-
plug configuration
Plain barrel center contact.
NOT RECOMMENDED
Tuning-fork center
contact.
