2.2 Card Cage Considerations
IMPORTANT: Adequate air
circulation must be provided to
prevent a temperature rise
above the maximum operating
temperature.
Refer to the specifications for loading and power requirements. Be sure
that the system power supplies are able to accommodate the power
requirements of the carrier board, plus the installed IP modules, within the
voltage tolerances specified.
The dense packing of the IP modules to the carrier board restricts air flow
within the card cage and is cause for concern. Adequate air circulation
must be provided to prevent a temperature rise above the maximum
operating temperature and to prolong the life of the electronics. If the
installation is in an industrial environment and the board is exposed to
environmental air, careful consideration should be given to air-filtering.
2.3 Board Configuration
The carrier board may be configured for different applications. All possible
configuration settings will be discussed in the following Sections. The
jumper locations and IP module positions are shown in Drawing 4501-755.
Power should be removed from the board when installing IP modules,
cables, termination panels, and field wiring. Refer to Mechanical Assembly
Drawing 4501-756 and your IP module documentation for specific
configuration and assembly instructions.
2.4 VME64x Bus Interface Configuration
The carrier board is shipped from the factory configured as follows:
•
Carrier board with VME64x bus Short I/O Base Address of 0000H.
Board will respond to both Address Modifiers 29H and 2DH.
Registers on the carrier board plus the I/O and ID spaces on any
installed IP modules will be accessible.
•
Programmable software registers default to IP memory space
(VME64x bus standard address space) accesses disabled.
•
Programmable software registers default to IP interrupt requests-
disabled and VME64x bus interrupt level-none.
2.5 Address Decode Jumper Configuration
The carrier board interfaces with the VME64x bus as a 1K byte block of
address locations in the VME64x bus short I/O address space (refer to
Section 3 for memory map details). J1 decodes the six most significant
address lines A10 through A15 to provide segments of 1K address space.
