THE PCI-7230 PROVIDES 32 ISOLATED DIGITAL I/O,
16 ISOLATED INPUTS AND 16 ISOLATED OUTPUTS. THE ISOLATED I/O CHANNELS ARE
ISOLATED TO 2,500 VRMS ( EXCLUDING CABLES), BOTH CHANNEL-TO-CHANNEL AND
CHANNEL-TO-COMPUTER. IT PROTECTS YOUR COMPUTER AGAINST DAMAGE CAUSED BY
ACCIDENTAL CONTACT WITH HIGH EXTERNAL VOLTAGE AND ELIMATES TROUBLESOME
GROUND LOOPS.
THE PCI-7230 USES SAIC PCI CONTROLLER TO INTERFACE
THE BOARD TO THE PCI BUS. THE ASIC FULLY IMPLEMENT THE PCI LOCAL BUS SPECIFICATION
REV 2.0. ALL BUS RELATIVE CONFIGURATIONS, SUCH AS BASE MEMORY ADDRESS AND
INTERRUPT ASSIGNMENT, ARE AUTOMATICALLY CONTROLLED BY BIOS SOFTWARE. IT
DOES NOT NEED ANY USER INTERACTION AND PRE-STUDY FOR THE CONFIGURATIONS.
THIS REMOVES THE BURDEN OF SEARCHING FOR A CONFLICT-FREE CONFIGURATION,
WHICH CAN BE VERY TIME CONSUMING AND DIFFICULT WITH SOME OTHER BUS STANDARDS.

THIS CHAPTER DESCRIBES THE CONFIGURATIONS OF THE
PCI-7230 AND TEACH USERS TO INSTALL THE PCI-7230. AT FIRST, THE CONTENTS
IN THE PACKAGE AND UNPACKING INFORMATION THAT YOU SHOULD CARE ABOUT ARE
DESCRIBED. THE PCI-7230 IS PLUG-AND-PLAY; IT IS VERY EASY TO INSTALL INTO
ANY PC SYSTEM WITH PCI SLOTS.
IN ADDITION TO THIS USER'S MANUAL, THE
PACKAGE INCLUDES THE FOLLOWING ITEMS:
· PCI-7230 ISOLATED DIGITAL I/O CARD
DOS SOFTWARE LIBRARY AND UTILITY
IF ANY OF THESE ITEMS IS MISSING OR DAMAGED, CONTACT THE DEALER FROM
WHOM YOU PURCHASED THE PRODUCT. SAVE THE SHIPPING MATERIALS AND CARTON
IN CASE YOU WANT TO SHIP OR STORE THE PRODUCT IN THE FUTURE.
YOUR PCI-7230 CARD CONTAINS SENSITIVE ELECTRONIC
COMPONENTS THAT CAN BE EASILY DAMAGED BY STATIC ELECTRICITY.
THE CARD SHOULD BE DONE ON A GROUNDED ANTI-STATIC
MAT. THE OPERATOR SHOULD BE WEARING AN ANTI-STATIC WRISTBAND, GROUNDED
AT THE SAME POINT AS THE ANTI-STATIC MAT.
INSPECT THE CARD MODULE CARTON FOR OBVIOUS DAMAGE. SHIPPING AND HANDLING
MAY CAUSE DAMAGE TO YOUR MODULE. BE SURE THERE ARE NO SHIPPING AND HANDING
DAMAGES ON THE MODULE BEFORE PROCESSING.
AFTER OPENING THE CARD MODULE CARTON, EXTRACT THE SYSTEM MODULE AND
PLACE IT ONLY ON A GROUNDED ANTI-STATIC SURFACE COMPONENT SIDE UP.
AGAIN INSPECT THE MODULE FOR DAMAGE. PRESS DOWN ON ALL THE SOCKETED
IC'S TO MAKE SURE THAT THEY ARE PROPERLY SEATED. DO THIS ONLY WITH THE
MODULE PLACE ON A FIRM FLAT SURFACE.
NOTE : DO NOT APPLY POWER TO THE CARD IF IT HAS
BEEN DAMAGED.
YOU ARE NOW READY TO INSTALL YOUR PCI-7230.
FIGURE 2.1

OUTLINE
PCI-7230 HAS PLUG AND PLAY COMPONENT, THE CARD
CAN REQUESTS MEMORY USAGE (I/O PORT LOCATIONS) OF THE PCI-7230 IS ASSIGNED
BY SYSTEM BIOS. THE ADDRESS ASSIGNMENT IS DONE ON A BOARD-BY-BOARD BASIS
FOR ALL PCI-7230S IN THE SYSTEM.
YOUR COMPUTER WILL PROBABLY HAVE BOTH PCI AND
ISA SLOTS. DO NOT FORCE THE PCI-7230 INTO A PC/AT SLOT.
1. TURN OFF YOUR COMPUTER
2. TURN OFF ALL ACCESSORIES ( PRINTER, MODEM, MONITOR, ETC.) CONNECTED
TO COMPUTER.
3. REMOVE THE COVER FROM YOUR COMPUTER.
4. SELECT A 32-BIT PCI EXPANSION SLOT. PCI SLOT ARE SHORT THAN ISA OR
EISA SLOTS AND ARE USUALLY WHITE OR IVORY.
CAUTION !! DON`T PUT PCI-7230 CARD INTO ISA OR EISA CARD.
5. BEFORE HANDLING THE PCI-7230, DISCHARGE ANY
STATIC BUILDUP ON YOUR BODY BY TOUCHING THE METAL CASE OF THE COMPUTER.
HOLD THE EDGE AND DO NOT TOUCH THE COMPONENTS.
6. POSITION THE BOARD INTO THE PCI SLOT YOU SELECTED.
7. SECURE THE CARD IN PLACE AT THE REAR PANEL OF THE SYSTEM UNIT USING
SCREW REMOVED FROM THE SLOT.
A TESTING PROGRAM IS INCLUDED IN THIS UTILITY,
YOU CAN CHECK IF YOUR PCI-7230 CAN WORK PROPERLY. REFER SECTION 5.2 FOR
FURTHER DETAILED INFORMATION.

3.4 ISOLATED DIGITAL
INPUT CHANNELS
THE ISOLATED DIGITAL OUTPUT IS AN OPEN COLLECTOR
TRANSISTOR OUTPUT. THE INPUT ACCEPT VOLTAGE FORM 5V TO 24V AND INPUT RESISTER
IS 1.2K . THE CONNECTION BETWEEN OUTSIDE SIGNAL AND PCI-7230 IS SHOWN BELOW.
3.5 ISOLATED DIGITAL
OUTPUT CHANNELS
THE CONNECTION OF ISOLATED-DIGITAL OUTPUT IS SHOWN
AS FOLLOWING DIAGRAM. AN EXTERNAL VOLTAGE SOURCE ( 5~40VDC) IS NECESSARY
TO POWER THE INTERNAL ISOLATED CIRCUITS, AND IT IS CONNECTED WITH PIN-19
OF CN3. WHEN THE ISOLATED DIGITAL OUTPUT GOES TO HIGH, THE SINK CURRENT
WILL BE FROM VDD.

NAMING CONVENTION
THE FUNCTIONS OF PCI-7230'S SOFTWARE DRIVERS ARE
USING FULL-NAMES TO REPRESENT THE FUNCTIONS' REAL MEANING. THE NAMING CONVENTION
RULES ARE :
IN DOS ENVIRONMENT :
_{HARDWARE_MODEL}_{ACTION_NAME}. E.G. _7230_INITIAL
().
THERE ARE 4 FUNCTIONS PROVIDED BY PCI-7230 SOFTWARE
DRIVERS.
THE DETAIL DESCRIPTIONS OF EACH FUNCTION ARE SPECIFIED
IN THE FOLLOWING SECTIONS.
@ DESCRIPTION
THE PCI-7230 CARDS ARE INITIALIZED BY THIS FUNCTION.
THE SOFTWARE LIBRARY COULD BE USED TO CONTROL MULTIPLE PCI-7230 CARDS.
BECAUSE PCI-7230 IS IN PCI BUS ARCHITECTURE AND MEETS THE PLUG AND PLAY
SPECIFICATIONS, THE IRQ AND I/O ADDDRESS ARE
ASSIGNED BY SYSTEM BIOS DIRECTLY.
@ SYNTAX
C/C++ ( DOS)
U16 _7230_INITIAL(U16 *EXISTCARDS, PCI_INFO *PCIINFO
)
@ ARGUMENT :
EXISTCARDS :

PCI-7230 CARDS ARE INSTALLED IN YOUR SYSTEM.
PCIINFO: IT IS A STRUCTURE TO MEMORIZE THE PCI BUS PLUG AND PLAY
INITIALLIZATION INFORMATION WHICH IS DECIDED BY P&P BIOS. THE PCI_INFO
STRUCTURE IS DEFINED IN PCI_7230.H. THE BASE I/O ADDRESS AND THE INTERRUPT
CHANNEL NUMBER IS STORED IN PCIINFO WHICH IS FOR REFERENCE.
@ RETURN CODE :
U16 MEANS UNSIGNED SHORT INTEGER
ERR_NOERROR
ERR_PCIBIOSNOTEXIST
@ DESCRIPTION
THIS FUNCTION IS USED TO READ 16-BIT DIGITAL INPUTS
DATA FROM DIGITAL INPUT PORT. YOU CAN GET THE 16 BITS DATA FROM _7230_DI
BY USING THIS FUNCTION.
@ SYNTAX
C/C++ ( DOS)
U16 _7230_DI( U16 CARDNO, U16 *DI_DATA )
@ ARGUMENT :
CARDNO : CARD
NUMBER TO SELECT BORAD
DI_DATA : RETURN 16-BIT VALUE FROM DIGITAL PORT.
@ RETURN CODE :
ERR_NOERROR
@ DESCRIPTION
THIS FUNCTION IS USED TO WRITE DATA TO DIGITAL
OUTPUT PORTS. THERE ARE 16 DIGITAL OUTPUTS ON THE PCI-7230,
@ SYNTAX
C/C++ ( DOS)
U16 _7230_DO(U16 DO_DATA )
@ ARGUMENT :
CARDNO : CARD
NUMBER TO SELECT BORAD
DO_DATA : VALUE WILL BE WRITTEN TO DIGITAL OUTPUT PORT
@ RETURN CODE :
