J9 is installed when the –M option is requested. J9 is a two pin header. When a shunt
is installed the 1K Ω resistor provides a pull-down. When open a 10K Ω resistor provides
the pull-up. The installed PrPMC can usually override either setting after power-up
using software.
PCI2PMC is a product consisting of a PCB and added components. The components
can be swapped or left off to create different versions.
The standard version of the board is called “PCI2PMC” and comes with a complete 64
bit PCI path to support 32 and / or 64 bit operation at 33 and / or 66 MHz. The PMC
may have IO through its bezel or via Pn4 or both. The Bezel IO is supported via the
PCI rear IO port. The Pn4 IO is supported with either a DIN or SCSI connector. The
DIN connector is standard and the
–SCSI option swaps the DIN for the SCSI.
The PCI2PMC–ME version removes the Upper part of the PCI bus and the rear IO
leaving the primary 32 bit PCI path and PMC Bezel IO. This version is usually provided
with the –HC option to remove the regulator and FET’s etc. to provide a hardwired PCI
3.3V sourced board.
The PCI2PMC, PCI2PMC-SCSI, and PCI2PMC-ME-HC are stocked items. Other
combinations are built to order. Please see the last page for more ordering options.
