1 Introduction
Overview
Smartio - The Smart Multiport Async Solutions
The term Smartio stands for smart multiport serial I/O solution. The Smartio C168
Series multiport boards offer 8 serial ports for connecting terminals, modems,
printers, data acquisition equipment and any other serial devices to the PC/AT and
its compatible systems. With the well-designed and fine-tuned device driver, the
Smartio boards make full use of the 32 byte Tx/Rx FIFO and on-chip H/W flow
control, so that they can transfer data without data loss even at high speed such as
921.6 Kbps, which offers a reliable and high performance solution for serial
multiport communications.
The Smartio C168 Series 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. Full range of I/O addresses and IRQs are
available. In addition, with on-board EEPROM for storing the configuration data,
the family is designed without jumper or switch. These features make each port on
the board truly independent to any other port and thus compatible with most existing
multiport boards.
The Smartio C168 Series is also available in PCI bus. Please contact MOXA
dealer/distributor or MOXA Web site for more details.

New : set I/O address Traditional : set switch and

Utility. 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.exe, which
read and write the on-board EEPROM for configuration information through the
CAP (Configuration Access Port) address. The CAP address is the only channel
via which the configuration utility Io-irq.exe can access the board, which is identical
to the first port's base I/O address.
The only jumper, JP1, is designed in case that users forget the CAP address.
Normally JP1 is left open. When JP1 is short, the CAP address is forced to a fixed
I/O address, 0xA700. However, to adopt quick installation (described later), it is a
must to keep JP1 always short.
Quick Installation
To ease the hardware configuration, users who install only one Smartio C168
Series board under Windows NT/95/98 are recommended to adopt quick
installation described in Chapter 2.
Because the family is so flexible in hardware configuration that they are compatible
virtually with all kinds of other manufacturer's multiport boards using 16450 or
16550 UART.

Introduction
Smartio C168H/HS User’s Manual 1-3
Surge Protection
To prevent the boards from damage caused by lighting or high potential voltage,
surge protection technology is introduced in some model to protect the board.
Operating System Support
The family is operational under most popular operating systems such as Windows
NT, Windows 95/98, SCO UNIX/XENIX/OpenServer, DOS, Linux, QNX,
FreeBSD, UNIX SVR4.2, However, MOXA device drivers for Windows NT,
Windows 95/98, Linux, SCO UNIX/OpenServer, UNIX SVR4.2 and DOS are
provided for easier installation, configuration and better performance. In this
manual, chapters for MOXA Windows NT,Windows 95/98,UNIX and DOS
device drivers are included. For other compatible systems not mentioned, please
refer to the respective operating system’s manual for how to install and configure
the standard driver.
MOXA Serial Comm Tools
For easy application development, MOXA provides an easy-use serial
communication library under Windows NT/95/98 (PComm) and DOS (API-232).
Users can use this library to develop your own applications using Microsoft C,
Turbo C, Assembly, QuickBASIC, Turbo Pascal, Clipper, Visual Basic, Visual C++,
Borland Delphi, etc. Utilities, such as diagnostic and monitor, are included for
diagnosing the board/port or monitoring the communication status.
Wide Applications
The Smartio C168 Series are suitable for many applications. Here are a few:
lInternet/Intranet Connection
lRemote Access Application
lMulti-user Application
lIndustrial Automation
lOffice Automation
lTelecommunication
lPC-based (vending) Machine or Kiosk System
lPoint-of-Sale (POS) System
