Save the shipping materials and carton for future storage or shipping purposes. 2.
2.3 Hardware Installation Outline PCI configuration The PCI cards (or CompactPCI cards) are equipped with a Plug and Play PCI controller, it can request base addresses and interrupt in accordance with the 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.
2.4 Device Installation for Windows Systems Once Windows 98/2000/XP has started, the Plug and Play function of Windows system will find the new NuDAQ/NuIPC cards. If this is the first time installing NuDAQ/NuIPC cards on your Windows system, you will be prompted to enter the device information source. Please refer to the “Software Installation Guide” for instructions on installing the device.

3 Registers Format The registers format is described in this chapter. This information is quite useful for programmers who wish to handle the card by low-level programming. However, it is recommended that the user has a deeper understanding of the PCI interface before starting any low-level programming. This chapter can also assist users in using the 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.
3.2 I/O Registers Format The PCI-7230/cPCI-7230/LPCI-7230 requires one 32-bit address in the PC I/O address space. Table 3.1 shows the I/O address of each register with respect to the base address. Address Write Read Base (0 - 1 ) Isolated DO Isolated DI Table 3-1: I/O Address Map of PCI-7230/cPCI-7230/LPCI-7230 The PCI-7233 requires one 32-bit address in the PC I/O address space. Table 3.2 shows the address.
3.3 Digital Input Register There is a total of 16 and 32 digital input channels on the PCI7230/cPCI-7230/LPCI-7230 and PCI-7233/7233H respectively. Each bit corresponds to a signal on the digital input channel. IDI_16 to IDI_31 are only available on PCI-7233/7233H.

4 Operation Theorem 4.1 Isolated Digital Input Circuits The isolated digital output is an open collector transistor output. The input can accept voltages of up to 24V. The input resisters on PCI-7230/7233/7233H, cPCI-7230 and LPCI-7230 are 1.2KΩ. The connection between outside signal and PCI-7230/7233/7233H, cPCI-7230 and LPCI-7230 are shown below.

It is connected with the VDD pin, When the isolated digital output goes to high, the sink current will be from VDD.

4.3 Change of State Detection What is COS? The COS (Change of State) occurs when the input state (logic level) is changed from low to high or from high to low. The COS detection circuit is used to detect the edge of level change. In the PCI-7233 card, the COS detection circuit is applied to all 32 channels input channels. If any channel is changed, the COS detection circuit generates an interrupt request signal.

COS Detection The following timing is an example of the COS detection. Every DI signal’s edge change can be detected. All the DI channels edge will be ‘OR’ together to generate the INT1 or INT2 IRQ signals. If INT1 or INT2 irq Signals generate, the signal will be latch its state. The user can use the “_7233_CLR_IRQ” function to clear, INT1, or INT2 IRQ signal state.
