Help: ICE_CARDS_PIC4X
PCI (64/32 bit, 66/33MHz, 3/5V) PM x1
INTRODUCTION
The ICE-PIC4X is driven by an Analog Devices 21160 SHARC DSP and interfaced
to the PCI bus by an Altera FLEX10K30E programmable logic device. It contains
module sites for two 16 bit digital in/outputs, a FLEX10K100 PLD for front end
bit processing, and one processor module site.
INSTALLATION
This card is a universal PCI card. If fits in either 64/32 bit, 3/5V, or
66/33MHz PCI slots. The edge connector has spacers to adjust to different
manufacturer's chassis tolerances.
Mounting a 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
Note: on some early models the dip switches are just jumpers.
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.
One on-board crystal X2 is socketed for an optional user supplied reference
clock. This clock can be used for driving A2D or D2E modules at fixed rates
or for special IOC code rates. By default, X2 is a 100MHz clock for maximum
bandwidth A2DR7 clocking.
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.
See the DRIVERS.HLP to install the software drivers.
MAINTENANCE
Hardware checkout procedures are automated in software by running the TEST
procedures in the PIC X-Midas macro. Special IOC programs are loaded to
perform loopback tests for all components except the modules.
