Overview
Smartio - The Smart Multiport Async Solution
The term Smartio represents smart multiport serial I/O solution. The Smartio
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

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 (PComm) 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.

6 Troubleshooting
Common Smartio C104H/PCI Series errors and possible corresponding solutions
are listed below. If the problem still cannot be solved by following solutions given,
contact dealers or Moxa for help or use the Problem Report Form at the end of
this manual to report problems to your dealer at once for faster technical support.
General Troubleshooting
1. The MOXA PCI board cannot be detected by the MOXA driver while
installing the driver.
Hardware causes and solutions:
A. The board is not installed or missing (absent). Please install it.
B. The board is not properly plugged in the system. If that is the case, re-
plug the board in a 32-bit PCI slot this time. Sometimes the slot for
plugging the board is malfunctioned. In this case, try other slots until you
find a good one.
C. The motherboard does not have an available IRQ for the C104H/PCI
Series board. Please enter BIOS and make sure there are available IRQ in
PCI/PnP settings.
2. The MOXA board and driver are activated but cannot transfer
(transmitting/receiving) data.
Hardware Causes and Solutions:
A. Check if cable wiring is connected correctly. Please refer to the
“Connection Cable and Cable Wiring” chapter for correct cable
connection.
B. The cable or the board are probably defective. Please try other ports,
cables or boards to verify it. Or use PComm Diagnostic utility testing
Smartio C104H/PCI Series User’s Manual 6-1
Download from Www.Somanuals.com. All Manuals Search And Download.
MOXA boards and port conditions. If Diagnostic reports error, replace
the malfunctioned faulty components.
Software Causes and Solutions:
A. Smartio C104H/PCI Series board will check the line status (CTS) before
transmitting data if the RTS/CTS flow control feature is set to Enable in
the configuration or application program. Please refer to the Connection
Cable and Cable Wiring chapter for proper wiring and check the line
status of the suspected port using the diagnostic LED indicators on the
mini tester.
B. The board controlling application might not be correctly written
according to the corresponding API of the operating system. To verify the
problem, please run another existing and known good application or the
utilities provided by Moxa. Such as Pcomm Terminal emulator or
HyperTerminal under Windows NT and Windows 95/98.
Windows NT
This section is specific for troubleshooting under Windows NT. For general
problems and solutions, please see the previous section, General Troubleshooting.
1. After the system reboots, the error message Another driver in the system,
which did not report its resources, has already claimed the interrupt used
by xxx. appears in the Event Log.
This indicates the MOXA board is found, but the IRQ is conflicting with
another adapter. Please check the PCI BIOS IRQ settings first and then select
an IRQ that is available.
2. After the system reboots, the error message “Cannot find any configured
MOXA Smartio/Industio series board!” appears in the Event Log.
Please make sure the PCI board is seated firmly in the expansion slot.
3. The COM number of the Smartio C104/PCI Series (Bus No=x Dev No=x,
Port1=COMx), with device number xx, conflicts with others.
The COM numbers for different boards are conflicting. Change the COM
number mappings for MOXA boards.

Troubleshooting
4. Windows NT system panic (blue screen).
The possible reason is an IRQ or I/O address conflict with other ISA Bus
adapters, like LAN and SCSI boards, or the system BIOS. Please refer to the
corresponding problem in the previous section “General Troubleshooting”
for solutions.
Windows 95/98
This section is specific for troubleshooting under Windows 95/98. For general
problems and solutions, please see the previous section, “General
Troubleshooting”.
1. The system fails to find the Smartio C104H/PCI Series board!
- The board(s) is(are) not plugged properly.
- The slot with boards plugging in is defective, please try another slot until you
find a good one.
- The board might be defective.
2. After the system reboots, the error message “C104/PCI Series (BusNo=x,
DevNo=x, Port1=COMx) interrupt number is invalid!” appears.
This indicates that the MOXA board is found, but the IRQ is conflicting with
other adapter. Make sure MOXA board’s IRQ is not conflicting with other
adapter’s. Check the PCI BIOS IRQ settings and select an available IRQ for
MOXA boards.

PCI
The 32-bit Smartio C104H/PCI Series board complies with the PCI specifications
2.1. Hardware configuration for IRQ and I/O addresses is automatically assigned by
the PCI BIOS. Hence, you must first plug the board before installing the software
driver.
Unlike ISA slots, different PCI slots in the same PC may have different bus
numbers and device numbers with respect to the PCI specifications. The same PCI
Smartio C104H/PCI Series User’s Manual A-1

board will have different system configurations if switching to a different PCI slot,
which may be called slot-sensitive or slot-dependent. This may also apply to PCI
slots in PC with different motherboard, which may use different device number
sets. For example, some use 17, 18, 19, and 20 for identifying the respective PCI
slots but some use 11, 12, 13 and 14.
Due to the slot-dependency, it is necessary to re-configure the software driver
once the board is plugged in different PCI slots.
Up to 4 Smartio C104H/PCI Series boards are allowed in one system. When
installing more than one board, please remember the order of boards for
distinguishing the installed boards.
UART 16C550C
The UART chip 16C550C is an intelligent asynchronous controller supporting one
full duplex channel that simultaneously transfers data at 921.6 Kbps speed. To
increase the overall data throughput, special features such as on-chip FIFO and on-
chip hardware flow control are used to reduce the number of interrupts to the
onboard CPU and to prevent any loss of valuable data.
