CHAPTER 2 1 General Information Sections include: • Features • Applications • Installation Guide • Software Overview • Device Driver Programming Roadmap • Accessories
Chapter 1 General Information The PCI-1737U/PCI-1739U is a 24/48-bit DI/O card with PCI bus. It provides you with 24/48 bits of parallel digital input/output. It emulates mode 0 of the 8255 PPI chip, but the buffered circuits offer a higher driving capability than the 8255. The I/O bits are divided into three 8-bit I/O ports: A0, B0, and C0.( Six for PCI-1739U, A0, A1, B0, B1, C0, C1) You can configure each port as either input or output via software.
1.2 Applications • Industrial AC/DC I/O module monitoring and control • Relay and switch monitoring and control • Parallel data transfer • Sensing the signals of TTL, DTL, CMOS logic • Driving indicator LED's 1.

CHAPTER 3 2 Signal Connections .
Chapter 3 Signal Connections Maintaining signal connections is one of the most important factors in ensuring that your application system is sending and receiving data correctly. A good signal connection can avoid unnecessary and costly damage to your PC and other hardware devices. This chapter provides useful information about how to connect input and output signals to the PCI1737U/PCI-1739U via the I/O connector. Figure 3.

CHAPTER 4 2 Operation Sections include: • Configuration • 8255 Mode 0 Function Definitions • Interrupt Handling
Chapter 4 Operation This chapter describes the operating characteristics of the PCI-1737U/ PCI-1739U. The DLL driver 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. 4.
4.2.1 Interrupt Function of the DIO Signals The I/O pin (PC00) can be used to generate hardware interrupt. A user can program the interrupt control register (Base + 8) to select the interrupt sources. Refer to "Interrupt Function" in this chapter for details about interrupt control. 4.2.2 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 set as output ports via switches (refer to Section 3.
4.2.3 Initial Configuration The initial configuration of each port depends on the switch setting (SW1/SW2 for PCI-1737U and SW1/SW2/SW3/SW4 for PCI-1739U) If SW1 is set to “OFF” , all ports configured by software are automatically set as input ports during system start up or reset, with a default signal level of logic 1 (high). All ports are set as output ports during system start up or reset when SW1 is set to “ON”, signal level depends on SW2.
M00 and M01: mode bits of port0 E0: triggering edge control bits F0: interrupt flag bit 4.3.3 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 for port. Table 3-3 shows the relationship between an interrupt source and the values in the mode bits. Table 4.
4.3.5 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. Table 4.
