Zodiak Installation and Service Manual
Section 6 — Functional Description
Control Panel Processor board functionality is summarized below.
•
On-board 586 Class PC for control functions,
•
Disk-on-chip replaces a hard drive for storing operating software and
IP addresses,
•
10/100BaseT Ethernet LAN communication with Link LED indicator
for connection to Video Processor frame on Panel LAN,
•
Passive crossover switch for swapping Main panel to Frame Ethernet
cable TX and RX polarity,
•
Floppy disk drive for use with recovery floppy disks supplied with the
system,
•
Data transfer FPGA for interfacing to the Crosspoint Switch and M/E
Switch board controls via 8-bit parallel interfaces,
•
Two RJ45 LAN connectors for control and connection to Satellite panels
1 and 2,
•
Ten position boot mode selection switch (for diagnostic and setup func-
tions),
•
Reset switches for Main panel (RT panel), Menu panel and a Master
reset for both,
•
Power regulating, monitoring, and fusing of + 5 V and + 12 V from
Main and Redundant power supplies to other required voltages and
distribution to on-board areas and other boards in the panel and the
Menu panel, and
•
Four GPI output relays and four GPI opto-inputs for interfacing to
external devices.
Floppy Disk Drive
The floppy disk drive mounted on the Control Panel Processor board in the
Main panel tub is provided for running an emergency recovery procedure
loaded on two floppy disks provided with the system. The floppy disks
completely reformat the Main panel hard drive disk-on-chip and restore
the default IP addresses set at the factory to return the panel to a known
default state for troubleshooting. These disks should only be used for the
emergency recovery procedures and not for any other purpose. Refer to
Reformat Main Panel Hard Drive and Restore IP Addresses on page 174
Crosspoint Switch Board
The Crosspoint Switch board is mounted inside the Main panel lid on the
left (
). It contains the source select push buttons and
control circuitry for the PVW/AUX, M/E and PGM/PST key and back-
ground buses, and the Key Bus Delegate and Preview subpanels.
