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.,
without running configuration program: Io-irq.exe

time while doing the software configuration.

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.

2. Power off the PC.
3. Make sure no hardware conflict and plug the board in a free 16-bit slot of the PC,

+ 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.

Normal speed ranges from 50 bps to 115.2 Kbps. High speed
ranges from 50 bps to 921.6 Kbps. C104P support only normal
speed spectrum. In other word, it is not available for speed
faster than 115.2K bps.
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.
5. Press F10 to save the configuration and exit the utility.
