2. General
The SSI 1417 is a PCI-card for evaluation of 2 SSI-encoders. Additionally there
are2inputstosettheencoderstozeroand2inputsfortriggereddataaquisition.
The card also contains a timer for time driven data aquisition.
Available options:
•Opto-isolation
3. Function
The SSI 1417 will use one PCI-slot within the pc. Because the PCI-bus supports
plugandplay,therearenojumpersorswitchestochangeconfiguration.Thecard
will use 8 x 32-bit-IO-addresses for the function and 16 x 32-bit-IO-adresses for
thePCI-target-controller.YoucanuseanynumberofSSI1417withinonepc(de-
pends on number of PCI-slots). The standard drivers supports up to 4 cards. If
more than 4 cards should be used, you can ask for a driver for more cards. The
cardhasone9-pinSUB-Dmaleconnectorfortheinputsandtwo 9-pinSUB-Dfe-
male connectors for the encoders.
The functions of the card will be handled in a FPGA. This free pro-
gramable device makes it possible to support customer specific
functions without changing the hardware. It is possible to imple-
ment additional special functions or fast controllers within the
FPGA.

5. Hints against noisy environment
All inputs and outputs are protected against noisy environment and high voltage
spikes.Neverthelessthe locationshouldbeselected toensurethatno capacitive
orinductiveinterferencecanhaveaneffectontheinstrumentorconnectionlines.
It is advisable:
•To use shielded, twisted pair cables.
•The wiring of shields and ground (0V) should be star-shaped.
•The distance to interference sources should be as far as possible. If necessa-
ry, protective screen or metal enclosures must be provided.
•Coils of relays must be supplied with filters.
•Parallel wiring of input signals and AC power lines should be avoided.
