Circuit Boards Required for All Configurations
The following circuit boards are required in every PDR100:
• Processor
• VGA-I/O
• Reference Genlock
• Master Disk Recorder
• RS-422 Interface
Processor
The Processor is always installed in slot J1. It communicates with the outside world
through the RS-422 Interface circuit board (that is installed in J17), RS-232 interface,
VGA, mouse keyboard combination, and if installed, a Local Area Network (LAN)
circuit board.
VGA-I/O
The VGA-I/O board is always installed in slot J2 next to the Processor board. In
addition to the video interface for the monitor, this board provides internal
connections to the PDR100’s RS-232 Serial port, the system hard disk drive, and the
floppy disk drive. There is also a parallel port, the IDE interface for the system hard
disk, and the floppy disk driver.
Reference Genlock
Slot J16 is assigned to the Reference Genlock circuit board. It requires both EISA bus
and Video Router connections. Like its neighbor the RS-422 Interface circuit board,
it is required for all configurations.
Master Disk Recorder
Each Disk Recorder circuit board requires a set of four or eight hard disk drives. This
can be as many as 12 hard disk drives per Disk Recorder, when the PDX103 is also
used. The Master Disk Recorder circuit board is always located in slot J14. It controls
4, 8, or 12 hard disk drives, depending on the number of hard disk drives installed and
whether the PDX103 is in use.
