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.

2.2 Unpacking

Your PCI -9111 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.

Installation • 7

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 -9111.

2.5 Hardware Installation Outline

Hardware configuration

The PCI cards (or CompactPCI cards) are equipped with plug and play
PCI controller, it can requests base addresses and interrupt according to
PCI standard. The system BIOS will install the system resource based on
the PCI cards’ configuration registers and system parameters (which are
set by system BIOS). Interrupt assignment and memory usage (I/O port
locations) of the PCI cards can be assigned by system BIOS only. This
system resource assignment is done on a board-by-board basis. It is not
suggested to assign the system resource by any other methods.

PCI slot selection

The PCI card can be inserted to any PCI slot without any configuration for
system resource.

Registers Format

The detailed descriptions of the registers format are specified in this
chapter. This information is quite useful for the programmers who wish to
handle the card by low-level programming. However, we suggest users
have to understand more about the PCI int erface then start any low-level
programming. In addition, the contents of this chapter can help users
understand how to use software driver to manipulate this card.

3.1 PCI PnP Registers

This PCI card functions as a 32-bit PCI target device to any master on the
PCI bus. There are three types of registers: PCI Configuration Registers
(PCR), Local Configuration Registers (LCR) and PCI -6308 registers.

The PCR, which is compliant to the PCI-bus specifications, is initialized
and controlled by the plug & play (PnP) PCI BIOS. User‘s can study the
PCI BIOS specification to understand the operation of the PCR. Please
contact with PCISIG to acquire the specifications of the PCI interface.

The PCI bus controller PCI-9050 is provided by PLX technology Inc.
(www.plxtech.com). For more detailed information of LCR, please visit
PLX technology’s web site to download relative information. It is not
necessary for users to understand the details of the LCR if you use the
software library. The PCI PnP BIOS assigns the base address of the LCR.
The assigned address is located at offset 14h of PCR.

The PCI -6308 registers are shown in the next section. The base address,
which is also assigned by the PCI PnP BIOS, is located at offset 18h o f
PCR. Therefore, users can read the 18h of PCR to know the base
address by using the BIOS function call.

Please do not try to modify the base address and interrupt which assigned
by the PCI PnP BIOS, it may cause resource confliction in your system.

3.2 I/O Address Map

Most of the PCI -9111 registers are 16 bits. The users can access these
registers by 16 bits I/O instructions. The following table shows the
registers map, including descriptions and their offset addresses relative to
the base address.

I/O Address Write Read

Base + 44h Timer 8254 Ch#2
Base + 46h Timer Control Timer Status
Base + 48h Clear H/W IRQ (Not used)

Table 3.1 I/O Address

3.3 A/D Data Registers

The PCI -9111 A/D data is stored in the FIFO after conversion. The data
can be transferred to host memory by software only. The register format
for 12 bits PCI -9111DG and 16 bits PCI-9111HR is bit-wise alignment but
not fully compatible. For 12 bits PCI -9111 data, the 4 LSBs are used to
memorize the channel number in which the AD data is stored.

PCI-9111HR. AD0 is the Least Significant Bit (LSB).

3.4 A/D Channel Control Register

The PCI-9111 provides 16 single-ended analog input channel. The
channel control register is used to set the A/D channels to be converted.
Under non-auto scanning mode, the register sets the channel number for
conversion. Under auto -scanning mode, the register sets the ending
channel number.

Where:
CNn: Multiplexer channel number.
CN7 is MSB, and CN0 is LSB.

There are 8 bits in this register. The 4 LSBs (CN0~CN3) are used to
select on-board multiplexer. Usually, only the 4 LSBs are used and 16
input channels can be selected. However, if there is an extension board
which can provide extension ability to 256 analog input channels, the 4
MSBs (CN4~CN7) can also be used to control the extension board.
