Description
Multi-Channel Data System
The MCDS-AC port may be used instead of ADM to interface multiple ports
of a computer. An MCDS-AC port is required to interface each computer port
to the equipment using a DLC.
Major equipment items required to implement MCDS consist of
•
MCDS shelf
•
DLC
•
MCDS-AC
•
MCDS power supply unit
•
MCDS cabinet (optional)
•
Spectron patch panel and cables (optional)
MCDS cabinet
Two different enclosures are available:
•
A large cabinet (varying sizes and configurations) that can accommodate
two shelves and four patch panels
•
A smaller cabinet that accommodates one shelf only
MCDS shelf
The MCDS shelf houses a center-mounted power supply and four
asynchronous cards mounted on each side of the power supply (a total of
eight). It can be either a stand-alone unit on an equipment frame or mount in
the MCDS cabinet.
MCDS power supply
The MCDS power supply is an off-line, switched mode supply which provides
multiple, regulated, and protected DC voltage to the shelf backplane. It requires
1.7 amp from a 120 V, 60 Hz ac source. It supplies steady-state 140 watts
multiple, regulated, and protected DC voltage to the backplane. An optional
MCDS power supply is available that connects to 220 V, 50 Hz ac lines.
