1.1 Introduction The PCI-1757UP is a 24-bit DI/O card with PCI bus. It provides you with 24 bits of parallel digital input/output, and emulates mode 0 of the 8255 PPI chip, but the buffered circuits offer a higher driving capability than the 8255. The card emulates one 8255 PPI chips to provide 24 DI/O bits. The I/O bits are divided into three 8-bit I/O ports: A0, B0 and C0. You can configure each port as either input or output via software.

2.1 Initial Inspection Before starting to install the PCI-1757UP, make sure there is no visible damage on the card. We carefully inspected the card both mechanically and electrically before shipment. It should be free of marks and in perfect order on receipt. As you unpack the PCI-1757UP, check it for signs of shipping damage (damaged box, scratches, dents, etc.) If it is damaged or fails to meet its specifications, notify our service department or your local sales representative immediately.

2.3 Jumper & Switch Settings We designed the PCI-1757UP with ease-of-use in mind. It is a "plug and play" card, i.e. the system BIOS assigns the system resources such as base address and interrupt automatically. The following section describes how to configure the card. You may want to refer to the figure below for help in identifying card components. Figure 2-1: Location of connectors and jumpers Setting to Broad ID (SW1) This section describes how to set the Broad ID of PCI -1757UP.

8255 chip. Each of the 8255 chips has 24 programmable I/O pins that are divided into two 8-bit ports and two 4-bit ports, designated PA, PB PCL and PCH. Each port can be programmed as an input or an output port. User can set the corresponding ports to be configurable as input or output ports by switch SW2 or software. When “IO CF.” position is “ON”, user can set the ports to be input or output ports by the software. Else, when “IO CF.” position is “Off”, user can set the ports by the switch SW2 directly.
PAGE 17
If the jumper JP1 is at lower (1, 2) position and the initial configuration is caused by a reset, all ports will return to the states they had just prior to the reset. The reset must be a "hot" reset (power not disconnected) for enabled JP1 to return ports to their prior values. Otherwise, the card behaves as though JP1 were not enabled. 2.

2.5 Installation Instructions The PCI-1757UP can be installed in any PCI slot in the computer. However, refer to the computer user's manual to avoid any mistakes and danger before you follow the installation procedure below: 1. Turn off your computer and any accessories connected to the computer. Warning! TURN OFF your computer power supply whenever you install or remove any card, or connect and disconnect cables. 2. Disconnect the power cord and any other cables from the back of the computer. 3.

3.1 Overview This chapter describes the operating characteristics of the PCI-1757UP. The driver software provided allows a user to access all of the card's functions without register level programming. Please see the User's Manual for the driver bundled with this card for more information. For users who prefer to implement their own bit-level programming to drive the card's functions, information useful for making such a program is included in this chapter. 3.

• Output status can be read back. Input/Output Control A control word can be written to a port's configuration register (Base+3) to set the port as an input or an output port, unless the ports are sets via the switch. Table 3-1 shows the format of a control word.
PAGE 23
Initial Configuration The initial configuration of each port depends on the software or switch SW2 setting of each port as input or output port, on the setting of the jumper JP1 to set the hot reset type. 3.3 Interrupt Function Interrupt Function of the DIO Signals Two I/O pins (PC0 and PC1) can be used to generate hardware interrupts. A user can program the interrupt control register (Base + 32) to select the interrupt sources.
PAGE 24
Interrupt Source Control The "mode bits" in the interrupt control register determine the allowable sources of signals generating an interrupt. Bit 0 and bit 1 determine the interrupt source, as indicated in Figure 3-1. Table 3-3 shows the relationship between an interrupt source and the values in the mode bits.

E 1 0 Triggering edge of interrupt signal Rising edge trigger Falling edge trigger Table 3-4: Triggering edge control bit values Interrupt Flag Bit The "interrupt flag" bit is a flag indicating the status of an interrupt. It is a readable and writable bit. Read the bit value to find the status of the interrupt, write "1" to this bit to clear the interrupt. This bit must be cleared in the ISR to service the next incoming interrupt.
