Please follow the steps to install the PCI-7348/7396. u u u u u Check what you have (section 2.1) Unpacking (section 2.2) Check the PCB (section 2.3) Install the hardware (section 2.4) Please refer to the “Software Installation Guide” to install the software drivers. 2.
2.2 Unpacking Your PCI-7396 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.

2.4 Hardware Installation Outline Hardware configuration The PCI cards (or CompactPCI cards) are equipped with plug and play PCI controller, it can request 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.
2.5 Connectors’ Pin Assignment of PCI-7348 The I/O pin assignment of PCI-7348 is shown in the Figure 2.2.

2.7 Jumpers’ Description The PCI-7396 is a ‘plug and play’ add-on card using PCI bus. It is unnecessary for user to setup its base address and IRQ level to fit the hardware of your computer system. However, to fit users’ versatile operation, there are still a few jumpers to set the power-on-states of all I/O ports. 2.7.1 Power-on-state For all I/O ports of the PCI-7396, the power-on-states could be pulled high, pulled low, or floating. It is depended on the jumper settings. Table 2.
2.8 Termination Boards Supporting PCI-7396 can be connected with several different daughter boards, including DIN-100S, DIN-96DI, and DIN-96DO. The functionality and connections are specified as follows. 2.8.1 Connect with DIN-100S DIN-100S is a direct connector for the add-on card that is equipped with SCSI-100 connector. It is suitable for the simple applications that do not need isolated connection in front of the digital inputs or outputs of PCI-7396. 2.8.
3 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 user have to understand more about the PCI interface 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.
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-7396 registers are 32 bits. The users can access these registers by 32 bits I/O instructions. The following table shows the registers map, including descriptions and their offset addresses relative to the base address.
The PCI-7396 has 2/4 PPIs on board. Each PPI contains 5 registers, including Digital Data Register, Control Register, External Trigger Enable Register, External Trigger Disable Register, and COS Interrupt Control Register. In the following sections, the 5 registers of PPI1 will be introduced respectively. The registers of the other 3 PPIs are of the same configuration which will not be repeated in this manual. 3.
3.4 Control Register Each PPI’s control register is used to set its three ports to be as input or output one independently. Address: BASE + 04h Attribute: write only Data Format: Bit 7 6 BASE+ 04h BASE+ 05h BASE+ 06h BASE+ 07h x x x x x x x x 5 4 3 2 1 0 x x x x x x x x x x x x P1C x x x P1B x x x P1A x x x P1n : n: port number Set to be ‘0’ for input port , ‘1’ for output port 3.

Please refer to NEC's or Intel's data sheet for the full description of the 8254 operation.
4 Operation Theorem The operation theorem of the functions on PCI-7396 card is described in this chapter. The operation theorem can help you to understand how to manipulate or to program the PCI-7396. 4.1 Digital I/O Ports 4.1.1 Introduction The PCI-7396 has 2/4 PPIs on board. Each 24-bit PPI is divided into three 8-bit I/O ports: A, B, and C. All of these 6/12 ports can be programmed as input or output independent. 4.1.

4.2 8254 Timer/Counter Operation 4.2.1 Introduction One 8254 programmable timer/counter chip is installed in the PCI-7396. There are three counters in one 8254 chip and 6 possible operation modes for each counter. The block diagram of the timer /counter system is shown in Figure 4.3. EVENT (PIN 51) 8254 Chip Event Edge Control Counter #0 Event IRQ Gate='H' Timer #1 2 MHz Clock Gate='H' Timer #2 Timer IRQ Gate='H' Figure 4.3 Timer / counter system of PCI-7396.
4.3 Interrupt Circuit 4.3.1 System Architecture The PCI-7396‘s interrupt system is powerful and flexible, which is suitable for many applications. It is a Dual Interrupt System. The dual interrupt means the hardware can generate two interrupt request signals in the same time and the software can service these two request signals by ISR. Note that the dual interrupt do not mean the card occupy two IRQ levels.
4.3.3 Dual Interrupt System The PCI controller can receive two hardware IRQ requests. However, only one IRQ will be sent to PCI bus, the two IRQ requests must be distinguished by user’s interrupt service routine (ISR). The two IRQ requests are named as INT1 and INT2. INT1 comes from COS P1 & P2, P1C0, P1C3, or the event counter interrupt. INT2 comes from COS P3 & P4, P2C0, P2C3, or the timer interrupt. The sources of INT1 and INT2 is selectable by using the Interrupt Source Control (ISC) Register.
4.3.4 Interrupt Source Control (ISC) There are four bits to control the IRQ sources of INT1 and INT2. Table 4.1 shows the selection of the IRQ sources and the interrupt trigger condition. If the application needs one IRQ only, you can disable one of the IRQ sources by software. You can also disable both the two interrupts If you do not need any IRQ source.
By using the four signals: P1C0, P2C0, P1C3, and P2C3, user can utilize their combination to generate a proper IRQ for versatile applications. 4.3.5 Change of State (COS) Interrupt What is COS? The COS (Change of State) means when the input state (logic level) is changed from low to high, or from high to low. The COS detection circuit will detect the edge of level change. In the PCI-7396 card, the COS detection circuit is applied to all the input channels.
4.4 12V and 5V Power Supply The SCSI-100 connector CN1 provides +12V and +5V power supply (only for PCI-7348) for external devices. To avoid the short circuit or the overload of the power supply, the resettable fuses are added on all the power supply signals. The maximum current for 5V power supply is 0.5 A. If the load current is larger than this limitation, the resistance of the resettable fuse will increase for the reason of the rising temperature.
