Thank you for your selection of our PCI bus LSI-3104 encoder/linear scale interface card.。 In the field of automatio n, enco der and linear scale as feedb ack or measu ring element is common used in the microprocessor control system. But for the versatile application in PC based control, only a few selections you can make. We integrate 4 axes (channels) in one card with the state of the art technology of FPGA chip and provide photo coupler isolation and experienced functions such as external triggered latch function at 32 bit counter length. Low cost and high performance makes this card a better choice to use in the servo control feedback , 3D measuring system and other applications which are concerning encoder or linear scale .

HARDWARE SETTINGS
9.1 CARD ID SETTING
Since PCI cards have plug and play function, the card ID is required for programmer to identify which card he/she will control without knowing the physical address assigned by the Windows. A 4 bits DIP switch for extinguishing the 16 identical card.
The following example sets the card ID at 12.

10. BASIS OF OPERATIONS
10.1 ADDRESSING METHOD
LSI3104 use indirect R/W through PC's I/O port, and the data width is 16 bits. Due to LSI3104 is a PCI BUS card; the base add ress is assigned b y BIOS or Windows system. However we still offer a libra ry fo r get bas e add ress (G_p ci_adr.h,G_adr_s.obj) in DOS mode , whereas in Windows system we support DLL for application link. As the following diagram, PC writes at Base+0 I/O address to set up the index as t h e a d dr es s of on card registers. Any R/W to base+2 may follow to read or write data from/to the addressed register.

#define HARD_HOMING 0 //define HARD_HOMING register address Disable(); //disable interrupt OUTPORT（BASE + 0，HARD_HOMING）; //set up register index
OUTPORT
（
BASE + 2，0x0001）; //write data to HARD_HOMING register
Enable(); //enable interrupt
12.2 EXAMPLE 2 (USING C)

C language example as follows: ( BASE the I/O base address set)
#define UPDATE_CNTR 3 //address of UPDATE_CNTR of X axis #define
CNTR_HIGH_WORD
4 // address of READ_H_WORD of X axis
#define
CNTR_LOW_WORD
5 // address of READ_L_WORD of X axis
int Cntr_low_value; //declare Cntr_low_value as integer int Cntr_hi_value; // declare Cntr_hi_value as integer long Cntr_value; // declare Cntr _value as long integer
Disable(); //disable interrupt OUTPORT ( BASE + 0，UPDATE_CNTR)

setup address of UPDATE_CNTR
OUTPORT ( BASE + 2，0X0001)
; //
command to update
OUTPORT ( BASE + 0
，
CNTR_LOW_WORD
