Tip: Useful hints for better operation.
4. General
The counter card PCI 1389-S02 has two 32-Bit incremental up/down counter.
TheinputchannelsofthesecountersareprovidedwithisolatedRS422interfaces.
In addition there is one 16-Bit reference counter with a RS422 interface which is
also isolated.
For controlling tasks there are 4 isolated digital input channels and 4 isolated
digital output channels.
The two up/down counter can be programmed for 1-, 2-, or 4-fold mode counting.
It is also possible to use the counters as event counters. Alternatively there is the
possibilitytomeasure thetimeeventof each incrementwitha resolutionof 5 MHz
or 10 MHz. Additional it is possible to trigger on the change of the counting
direction.
The reference counter is able to trigger the two up/down counters. With the aid
of the reference counter it is also possible to generate constant time intervals for
measurements.
Thedigitalinputand outputchannelscanbe usedforcontrollingtasks.Inaddition
the digital input channel 0 can be used to trigger the two up/down counters either
with the raising edge or the falling edge of the input signal.

5. Function
ThePCI1389-S02hasaPCI-Target-ControllertoconnecttothePCI-bus,aFPGA
which contains the whole functionality of the card, and also 4 bidirectional
RS422-Ports, 8 unidirectional RS422-Ports, 4 digital inputs and 4 digital outputs.
To prevent damage, the card contains a galvanic (optical) isolation to the pc.
After a reset the FPGA will boot his configuration out of an serial PROM. The
FPGA-functions are not implemented as software, they are implemented as
hardware! So extremely high working speeds are possible. The functions of the
card can be totally changed only by exchanging the PROM.
Special-function -S01
The PCI 1389-S02 has 2 x 32-Bit-Incremental-counter/timer with RS422-Inputs,
1 x 16-Bit-Reference-counter/timer with RS422-Input, 4 digital, short circuit
protected outputs and 4 digital inputs.
The 32-Bit-counters could be used as incremental counter with 1-, 2-, 4-fold
evaluation or as event-counter with max. 10 MHz input frequency. It is also
possible to use these counters as timers with a timebase of 5/10 MHz. In this
mode the counter-value will be stored with each input-pulse. Because of the 1-,
2- and 4-fold mode it is possible to measure the time between all possible signal
edges. Each 32-Bit-counter has a 32 value deep FIFO to store the triggered
values. The triggering can be programmed separatly for each counter to softwa-
retriggering, reference-counter-triggering, digital-input-triggering or time-trigge-
red mode. It is possible to measure up to 10.000 values per second, depending
on the long latency of Microsoft Windows. On faster PC’s the number of meas-
urements per second increases.
The triggering on the change of the counting direction allows the measuring of
the minimum and maximum angle and the repeatability of this angles.
The reference-counter serves for synchronous data aquisition. It can be used as
incremental counter to trigger the main-counters at always the same machine-
position. Therefore a trigger is generated each incremental step (1-, 2-, 4-fold
evaluation) beginning after the first index-pulse (zero-pulse) of the reference-
counter. In another mode the reference-counter is used as a programmable timer
with up to 20 kHz to aquire the counter-values in equidistant time steps.
The digital in- and outputs can be used for controlling tasks. Digital input 0 could
also be used as external trigger input for one or both main-counter.
The PCI 1389-S02 has several additional parameters. With these parameters it
is possible to change polarity of reset-inputs, change rotation direction, data
aquisition on rising or falling edge and so on. So the card can be configured in
most environments and applications without changes on wiring. Because of the
RS422-inputs the card can be used in rough industrial environment.

6. Hints against noisy environment
All inputs and outputs are protected against noisy environment and high voltage
spikes. Nevertheless the location should be selected toensure that no capacitive
or inductive interferences can have an effect on the instrument or connection
lines.
It is advisable:
• To use shielded, twisted pair cables.
• The wiring of shields and ground (0V) should be star-shaped.
• Thedistancetointerferencesourcesshouldbeasfaraspossible.Ifnecessary,
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.
7. Installation
The installation of the card should only be done by qualified personal only. Before
installation all components have to be disconnected from power supply. Because
within PC’s and the peripherals are high voltages it is dangerous to life!
7.1. Hardware configuration
The PCI 1389-S02 uses plug and play and so there is no need for any settings.

7.1.2. Connection of encoders
The signals A, A#, B, B#, Z, Z# of the encoder must be connected to the card.
The signals A#, B# und Z# are the inverted signals of A, B and Z. Because the
PCI 1389-S02 uses RS422-receiver, the non inverting and the inverting signals
have to be connected.
The input A (non inverting and inverting!) should be connected to encoder-output
A (0°), the input B (non inverting and inverting!) to encoder-output B (90°). The
input Z (non inverting and inverting!) could be connected to the zero-output of the
encoder. The counter will then be reset at the index position of the encoder each
turn. Alternativly the Z input could be connected to an external zero position of a
machine or left open.
7.1.3. Connection of digital inputs
The PCI 1389-S02 contains 4 digital inputs. These inputs are highsidedriven and
high-activ. The input circuit is build as voltage divider (100kΩfixed resistor and
R33).
7.1.4. Connection of digital outputs
The PCI 1389-S02 contains 4 digital outputs. These outputs are short circuit
protected highside switches with a voltage range of 7 - 30 VDC.
7.2. Open PC
Beforeopeningthepc-casedisconnectpowersupply!Thecaseshouldbeopened
as described by the manufacturer of the PC.
7.3. Card insertion
While inserting the card you could be hurt. This is because all components on the
cards and in the PC have sharp pins. So this work have to be done carefully. The
PCI 1389-S02 should be placed in a free PCI-Slot. The card should be installed
vertically from above. Afterwards the slot plate of the card have to be screwed to
the backside of the PC-case.
7. Installation
ERMA-Electronic GmbH 10

The slot plate is used for mounting and also for shielding. Keep in
mind that removal of the plate will result in loss of shielding and card
and PC will be more sensitive to EMC. Additionaly the card won’t be
heldinslot-positionwhenexternalforcewillhappentotheconnected
cables. Then the card could move within the slot and that can result
in damage to the PCI1389-S02 and the PC! So, don’t remove the
slot plate!
7.4. Close PC
The case should be closed as described by the manufacturer of the PC.
7.5. Driver installation
On most Windows-versions you must have administrator rights to install
drivers.
7.5.1. Windows 95 / 98 / ME
Windows will recognize the new card and ask for the driver. The driver is on the
disc within the directory Win9x.
ATTENTION: Windows 95 does notsupport PCI-SubvendorID. So youcan’tuse
different cards with AMCC S5920Q. If that happens, please use Windows 98
instead.
7.5.2. Windows NT4.0
You have to start the program SETUP.EXE. The program is on the disc within
the directory WINNT40. The program will install the driver and the DLL.
7.5.3. Windows 2000
Windows will recognize the new card and ask for the driver. The driver is on the
disc within the directory Win2000.
7.6. Configure software
All example-programs are shipped as executable and source-code.
7. Installation
11 ERMA-Electronic GmbH

7.7. Test of the card
After installation the card could be tested. Therefor you can use the example-pro-
grams on the disc or the frontpanel-software.
8. The registers of the PCI 1389-S02
The PCI 1389-S02 uses 2 IO-address-ranges and 1 interrupt. Because of the
plug-and-play of the PCI-bus these data should be found out for direct program-
ming.Thereforefunctions oftheBIOS hastobe usedlikedescribedin “PCI BIOS
SPECIFICATION Revision 2.1" or later.
The PCI 1389-S02 uses a configuration space header type 00h. The datas could
be found in the PCI-configuration space on BaseAddress0, BaseAddress1 and
InterruptLine. With BIOS-functions the data couldbe read out of the configuration
space. BaseAddress0 is used for the PCI-target controller, BaseAddress1 for the
functions of the card.
If the PCI1389S02.DLL is used (described later), these informations are handled
within the dll.
8.1. Counterregisters for Counter 1 and 2
Read
BaseAddress1 + 0 Read fifo of counter 1
BaseAddress1 + 4 Read fifo of counter 2

The 32-Bit counter registers of counter 1 and 2 are used to read and write the
counters.Tosetacountervalue,thecountermustbestopped!Thecountervalues
can only be read out of the fifo. Therefore the counter has to be triggered or
latched.
8.2. Mode register
The mode register controls the modes of the PCI 1389-S02 and is used to start
and stop the counters. Unused bits should be masked or set to 0. The bits are
used as follows:

9. Programming
9.1. Programming under Windows 95/98/ME
Fortheprogrammingunderwindows95/98/MEthecardcomeswithaappropriate
driver. To keep the programming as easy as possible, all functions for the PCI
1389-S02 are placed in a dll. So there is no need to program the PCI 1389-S02
directly.
This dll contains 2 types of functions. At first there are low-level function which
can be used to handle the cards register. The second set of functions are
high-level functions. These high-level functions are using a bigger software-fifo
to handle higher trigger rates.
The PCI1389S02.DLL should be copied out of the corresponding driver directory
into the system folder or the project folder of the application.
9.2. Programming under Windows NT4.0/2000
For the programming under windows NT4.0/2000 the card comes with a appro-
priate driver. To keep the programming as easy as possible, all functions for the
PCI1389-S02areplacedinadll.SothereisnoneedtoprogramthePCI1389-S02

The PCI1389S02.DLL should be copied out of the corresponding driver directory
into the system folder or the project folder of the application.
9.3. Programming via the PCI1389S02-DLL
The DLL PCI1389S02.DLL provides the basic and the extended functions for the
work with the PCI 1389-S02. The low-level and high-level functions should not
be mixed, because this can result in mistakes. The return value of all functions
will show an incorrect execution if a 0 is returned. The function GetLastError can
be used to get a more detailed error message. Programs designed for
PCI1389S02-DLL can be used on Windows 9x/ME and also on NT 4.0/2000, if
the corresponding DLL is used.
