CP-132 Series Introduction Overview Industio - The Industrial Multiport Async Solution The term Industio stands for smart multiport serial I/O solution for industrial applications. The Industio CP-132 Series boards, including CP-132, CP-132I, CP-132S and CP-132IS, are designed for 16-bit ISA/EISA bus. They offer 2 independent RS-422/RS-485 serial ports for connecting data acquisition equipment and many other serial devices to the PC and its compatible systems.
CP-132 Series Introduction PCI Solution The board complies with PCI Spec. 2.1 needing neither switch nor jumper. The hardware configuration for the IRQ and I/O address is automatically assigned by the PCI BIOS. Hence, the board MUST be plugged first before installing the software driver. For more PCI information, please refer to Appendix “Technical Reference”.

CP-132 Series Hardware Installation The installation of the Industio CP-132 Series consists of hardware and software installation. The hardware installation is detailed in this chapter. The next chapter deals with the software installation for various operating systems. The no-switch-no-jumper Industio CP-132 Series board hardware configuration for IRQ number and I/O address is automatically assigned by the PCI BIOS. Hence, the board MUST be plugged first before installing the software driver.
CP-132 Series Hardware Installation Installing the Industio CP-132 Series board Step 1: Power off the PC. WARNING Make sure your system is switched off before you start installing any board. If you don’t, you may risk damaging your system and the board. NOTE Step 2: Remove the PC’s cover. Step 3: Remove the slot cover bracket if there is any. Step 4: Plug the Industio CP-132 Series control board firmly into a free 32-bit PCI slot.
3 3. Software Installation In this chapter, the software driver installation, configuration and driver update/removal procedures are described for various operating systems, including Windows NT, Windows 95/98 and DOS. Before proceeding with the software installation, complete the hardware installation, detailed in previous chapter, “Hardware Installation”.
CP-132 Series Software Installation Windows NT Windows NT supports up to 256 serial ports, from COM1 to COM256. To fully integrate the advanced features of Windows NT, multi-process and multi-thread, pure 32-bit Windows NT device drivers are developed for the Industio CP-132 Series multiport boards. The driver conforms to Win32 COMM API standard. • To install the driver for the first time, please go directly to the next section, “Installing Driver”.
CP-132 Series Software Installation 6. Click [Add] button to open Property dialog box to change port setting and advanced FIFO configuration done automatically by the system. 7. Select the newly plugged Industio CP-132 Series board from the b pull down list. 8. In the “Property” dialog box, select the desired port in the port list and click [Port Setting] to enter the individual “Port #” setting dialog box to change the port COM number mappings or FIFO settings.
CP-132 Series Software Installation If “Auto Enumerating COM Number” is checked and specify the COM number of the first port, subsequent ports are mapped to continuous COM numbers. For instance, if first port is mapped to COM3, then second port is mapped to COM4 sequentially. If “Auto Enumerating COM Number” is not checked, specify the COM number for individual port. For instance, the second port can be out of sequence, say COM10, while the first port is mapped to COM3.
CP-132 Series NOTE Software Installation Once the board and the driver are installed and the driver restarts successfully, you can start to develop applications with the PComm library (See “Serial Programming Tools” chapter) or the Microsoft Win32 API. You can also execute any ready-made applications, such as PComm utility Terminal emulator (See “Serial Programming Tools” chapter) or HyperTerminal to transmit/receive data, as well as Remote Access Service to provide dial-up networking capabilities.
