1 1 Introduction Overview The Standard Multiport Async Solutions The term Smartio stands for smart multiport serial I/O solution. The Smartio C104 Series multiport boards offer 4 serial ports for connecting terminals, modems, printers, data acquisition equipment and any other serial devices to the PC/AT and its compatible systems. The C104P is equipped with custom-designed ASIC chip which replaces lots of conventional ICs and reduces the board to half-size. The whole family supports 16 bit architecture.
Hardware Configuration Method JP1 Switch ON Jumper 1 2 3 4 C104P New : set I/O address and IRQ via software Utility. ......... ......... Traditional Multipoort Board Traditional : set switch and and jumper manually for I/O address and IRQ. Instead of using traditional jumper or switch for IRQ and I/O address settings, hardware configuration of each port is easily set by DOS utility, Io-irq.
Introduction Operating System Support The C104P is operational under most popular operating systems such as Windows NT, Windows 95/98, SCO UNIX/XENIX/OpenServer, DOS, Windows 3.x, OS/2, Linux, QNX, FreeBSD, etc. However, MOXA device drivers for Windows NT, Windows 95/98, Linux, DOS and Windows 3.x are provided for easier installation, configuration and better performance. In this manual, chapters for MOXA Windows NT, Windows 95/98, DOS and Windows 3.x device drivers are included.

Introduction Check List Upon unpacking the C104P package, you should find the following items in the package, v v v v v C104P 4-port serial async board Device driver diskettes: l Windows NT and Windows 95/98 ¡Ñ 1 l DOS/Windows 3.
Installation Guide This section gives a brief summary of how to install the C104P under each supported operating system. The installation is simple and involves the following stages: Configure C104P with io-irq.exe.
2 2 Hardware Installation The installation of the C104P 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.
Now you should do either the normal hardware installation (detailed in the later section, “Hardware Installation with IO-IRQ Utility”) or the quick hardware installation (detailed right in the next section, “Quick Hardware Installation”). The latter is provided to facilitate the hardware installation, only under the circumstances that: u u u Only one C104P board is allowed to install in a system. Windows NT and 95/98 are the only operating systems supported.
Software Installation 5. DO power OFF and then ON (or Reset) the PC. (Please cold start.) 6. Restart System (Windows NT/95/98). It is very important to keep the JP1 always short in this case. Without running the hardware configuration program, Io-irq.exe under DOS prompt, the software configuration program will automatically update the hardware settings of the board while updating the software settings. This saves the trouble doing hardware configuration.
2. Power off the PC. 3. Make sure no hardware conflict and plug the board in a free 16-bit slot of the PC, one board at a time with JP1 open. + If you are installing multiple boards, insert one board at a time and configure it using the Io-irq program before inserting the next board. This is to prevent conflict between two boards with same default hardware settings.
Software Installation 1. Run the utility “Io-irq.exe” contained in the driver diskette to set up I/O address, IRQ and INT vector of the board. 2. Select “Smartio/Industio ISA Family” and press ENTER key.
3. Enter the CAP address of the C104P board to be configured. 4. Configure the following parameters as necessary. Port Index Indicate the port index for each port. I/O address Enter the base I/O address for each port, either sequentially or not. Avoid to conflicting with any other devices. IRQ Enter the IRQ, 2, 3, 4, 5, 7, 10, 11, 12 or 15, for each port, independently or not. Speed This field specifies the use of normal or high speed capability. Normal speed ranges from 50 bps to 115.2 Kbps.
Software Installation INT Vector Enter the interrupt vector I/O address for all ports. I/O address for interrupt vector is from 00000H to 0FFFFH. Interrupt vector is one byte of I/O address, in which each bit is used to indicate the occurrence of interrupt for corresponding port. To use interrupt vector, type in the hardware Interrupt vector I/O address. If not using interrupt vector, type 0 or leave blank as the interrupt vector. There are two modes for the C104P driver.
