Overview
SSmmaarrttiioo - The Smart Multiport Async Solution
The term SSmmaarrttiioo represents smart multiport serial I/O solution. The SSmmaarrttiioo
C104H/PCI Series boards, including C104H/PCI and C104HS/PCI, are designed
for 32-bit PCI bus with Plug and Play feature. They offer 4 RS-232 serial ports for
connecting terminals, modems, printers, scanners, cash registers, bar code readers,
keypads, numeric displays, electrical weighing machines, data acquisition
equipment and many other serial devices to the PC and its compatible systems. With
a well-designed and fine-tuned device driver, the Smartio board makes full use of
the 32 byte Tx/Rx FIFO and on-chip H/W flow control, which makes it possible
transferring data without loss at high speed as 921.6 Kbps. They offer a reliable and
high performance solution for serial multiport communications.
Board Applications
The board applies for many applications. Here are a few:
11
l Internet/Intranet Connection
l Remote Access Application
l Multi-user Application
l Industrial Automation
l Office Automation
l Telecommunication
Smartio C104H/PCI Series User’s Manual 1-1
l PC-based (vending) Machine or Kiosk System
l Point-of-Sale (POS) System
PCI Solution
The board complies with PCI Spec. 2.1 needing neither switch nor jumper. The
hardware configuration for the IRQ and Memory addresses 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”.
Surge Protection
To prevent the board from damage caused by lightning or high potential voltage,
TVSS (Transient Voltage Surge Suppressor) technologies are used in some
connection options to protect the multiport controller. This is remarkably required
for harsh environment such as factory, severe weather such as lightning, or other
high interference situations.
Operating System Support
With user-friendly installation, configuration and performance, it supports Windows
NT, Windows 95/98 and DOS.
MOXA Serial Comm Tool
For application development, MOXA provides an easy-to-use serial communication
library (PPCCoommmm) under Windows NT and Windows 95/98. With this library, it is
easy to develop your own applications using sample applications developed with
Visual Basic, Visual C++, Borland Delphi, etc. Utilities, such as diagnostic, monitor,
terminal emulation, etc., are also included for debugging and monitoring the
communication status, terminal emulation, and even file transferring.

The installation of the Smartio C104H/PCI Series consists of hardware and software
installation. The respective sections of the operating systems in the next chapter will
discuss more about the software installation. The hardware installation is described
in this chapter.
The no-switch-no-jumper Smartio C104H/PCI Series board hardware configuration
for IRQ number and I/O addresses is automatically assigned by the PCI BIOS.
Hence, the board MUST be plugged first before installing the software driver.
Installing the SSmmaarrttiioo C104H/PCI 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.
Step 2: Remove the PC’s cover.
Step 3: Remove the slot cover bracket if there is any.
Step 4: Plug the Smartio C104H/PCI Series control board firmly into a free 32-
bit PCI slot.
Step 5: Fasten the holding screw to fix the control board in place.
Step 6: Replace the system cover.

Step 8: Power on the PC and the BIOS will automatically set the IRQ and I/O
address.
Note! Each board must occupy one unique IRQ and four 8-byte I/O
addresses, which are assigned automatically by the PCI BIOS.
However, you can select a free IRQ number manually via the
PC’s BIOS setup for the PCI slot, but normally this method is not
available for the I/O address. The possible IRQ numbers are 2, 3,
4, 5, 7, 10, 11, 12, and 15. The possible I/O addresses are from
0x0000 to 0xFFFF.
