1. FORWARD
Thank you for your selection of our PCI bus LSI-3104 encoder/linear scale interface card.
。
In the field of automation, encoder and linear scale as feedback or measuring 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 .
Other
encoder/linear scale interface card:
LSI-2104 ISA bus encoder/linear scale interface card (4 axes)
ENC-9266 ISA encoder/linear scale interface card (3 axes)
Any comment is welcome,

9. 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 address is assigned by BIOS or Windows system.
However we still offer a library for get base address (G_pci_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 the address
of on card registers. Any R/W to base+2 may follow to read or write data from/to the
addressed register.
