1 Introduction
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
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 C104P board is also available in PCI bus. Please contact MOXA
dealer/distributor or MOXA Web site for more details.

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.
C104P
Default Settings
The C104P has the following default (factory) settings:
I/O address:
IRQ: 10
INT Vector: 0x1C0
CAP Jumper JP1: Open
Note ! If the default settings above are what you desire and good for the
0x180 (Port 1), 0x188 (Port 2), 0x190 (Port 3), 0x198 (Port 4)
system without conflicts, you may simply install the board in the
system and go directly to the next chapter, “Software Installation”.
Otherwise, follow the instructions below.
C104P User’s Manual 2-1
Now you should do either the normal hardware installation (detailed in the later
section, “Hardware Installation with IO-IRQ Utility”) or
installation
latter is provided to facilitate the hardware installation, only under the
circumstances that:
u Only one C104P board is allowed to install in a system.
u Windows NT and 95/98 are the only operating systems supported.
u I/O address 0xA700 must be free
(detailed right in the next section, “Quick Hardware Installation”). The
Quick Hardware Installation
To fully utilize the superior feature of flexible hardware configuration design of the
C104P, a quick and easy method of installation is designed for users, which
absolutely free the users from hardware configuration effort, i.e.,

installation
. Simply always short the
How to Do Quick Hardware Installation
Users who install only one C104P board under Windows NT/95/98 are strongly
recommended to do the quick installation as follows:
1. Short the jumper JP1 on the upper-left corner of the board.
2. Plug the board in PC with the desired system installed, which is powered off in
advance.
3. Process software installation, detailed in the next chapter.
This is to specify the desired I/O address, IRQ and INT Vector in the software
configuration panel, no matter what hardware settings are on the board. The
software configuration program will automatically update the hardware settings.
After this, users already complete the whole installation.
4. Shutdown System (Windows NT/95/98).
2-2 C104P User’s Manual
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. However, remember to
time the configuration changed.
Hardware Installation with IO-IRQ Utility
This section is for those who can not use quick hardware installation:
u Install two or more C104P boards in a system.
u Fail to install, due to the I/O address 0xA700 is not available or has conflict in the
system.
u Use operating systems other than Windows NT and 95/98.

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. One is using
interrupt vector, the other is not using interrupt vector. Driver
employing interrupt vector scheme is supposed to have better
performance than employing polling scheme.

General Troubleshooting
1. The MOXA driver, while installing the driver, cannot detect the MOXA
board.
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-install
the board and make sure that it fits well in a 16-bit slot this time. Sometimes
the slot for plugging the board is bad. In this case, try other slots until you
find a good one.

2. The MOXA board and driver are activated but cannot transfer
(transmit/receive) data.
Hardware Causes and Solutions:
a. Check for wrong cable wiring. Refer to the “Connection Cable and Cable
Wiring” chapter for precise pin outs of the connector type you are using.
b.
The cable or the board is defective. You may use other ports, cables or boards
to verify. In addition, the
Windows 95/98 is good for testing MOXA boards and port conditions. If
Diagnostic reports error, replace the faulty components.
PComm “Diagnostic” utility for Windows NT and
C104P User’s Manual 6-1
Software Causes and Solutions:
a. C104P checks the line status (CTS) before it sends data out 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. Check the line status of the suspected port using the
diagnostic LED indicators on the mini tester.
b. Perhaps the application controlling the board is not correctly written
according to the corresponding API of the operating system. To verify,
please run an existing and known good application or the provided utilities
by Moxa. For example, under Windows NT and Windows 95/98,
“Terminal emulator” or “HyperTerminal” utilities are good for testing the
COM ports.
3. Why the DOS utility IQ-IRQ can not access C104P to configure?
There are several reasons that may lead to this trouble:
a. The user forgets or does not know the Configuration Access Port (CAP) of
the board. See next problem
b. The CAP of the board conflicts with other add-on boards’ I/O address.
Please change other add-on boards’ I/O address to avoid the conflict.
c. The C104P board is not plugged in a right or good slot. Please plug the
board in a good 16-bit ISA slot.
d. The C104P board may malfunction. Please return for repair.
4 for how to solve this problem.
Pcomm
If any existing board has the same I/O address as 0x180, the
address, or the 1st port's I/O address, you must try to avoid the conflict by doing
either one the following.
a. Install a jumper (short) at position JP1 on the upper-left corner of the board.
b.
4. What to do if user forgets or does not know the Configuration Access Port
(CAP) address of C104P?
The C104P multiport board is designed without jumper or switch, so the
configuration is completed only by DOS utility Io-irq.exe.
To configure the board, you need to know the board’s Configuration Access Port
(CAP) address. Because the CAP address is the only channel, via which the Io-
