PCI (64/32 bit, 133/100/66/33MHz, 3V) PM x2


This card is a 3.3V only PCI card.  If fits in either 64/32 bit, 3V, 
133/66/33MHz PCI slots.  Jumper J4 is closed for PCI, open for PCI-X.
Currently, PCI-X mode is not supported.

The card has a status LED next to the edge connector SMB.  When the card 
is booted, the green LED flashes at 1Hz=66MHzPCI, 1.5Hz=100MHzPCI,
or 2Hz=133MHz PCI.  The red LED indicates PC transfers to/from the card.

Mounting an I/O module requires approximately 0.6 inches of slot width.   
All external module connectors are available at the card's edge connector.

The edge connector has 1 SMB connector to provide an external clock 
for output modules or a signal for synchronizing multiple cards.

There are 3 dip switches for configuring the external clock/sync connector:

  J1 - close for on board 50 ohm termination, open for high impedance
  J2 - close for multi-board signaling (external sync), open for clock
  J3 - close for DC coupled TTL clock, open for AC coupled 1Vpp sinusoid clock

where closed is towards the main board.

To synchronize acquisition/playback between multiple cards, J2 must be in 
place (closed) for both the master and slaves.  The Master asserts the XSOE
flags to drive the line.  The J1 terminators should be open.  Add J3 for 
2.5V 10kohm pull-up/dn and diode protection on the input/output.

The PIC5s internal 8-bit test port can also be used to synchronize multiple
cards.  In this case the Master asserts TPOE to drive the test port and
the slaves need the XTGO and XSTP flags.

The PIC5 onboard crystal is a fixed 100MHz clock.  User crystals must be 
mounted on the I/O modules themselves.  A programmable clock is available
on the mainboard for digital signals.

NOTES: 

1) The headers on the board are static sensitive.  Do not handle the board
	without taking proper static discharge precautions.
2) Make sure all connectors are oriented properly.
