1 Introduction  
Overview  
Sma rtio - The Smart Multiport Async Solutions  
The term Smartio stands for smart multiport serial I/O solution. The Sma rtio 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.

Traditional : set switch and  
and jumper manually for  
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 Sma rtio 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.

2 Hardware Installation  
The installation of the Smartio C168 Series 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.  
JP1  
Sma rtio C168 Series  
Default Settings  
The Smartio C168 Series has the following default (factory) settings:  
I/O address:  
0x180 (Port 1), 0x188 (Port 2), 0x190 (Port 3), 0x198 (Port 4)  
0x1A0 (Port 5), 0x1A8 (Port 6), 0x1B0 (Port 7), 0x1B8 (Port 8)  
IRQ:  
10  
INT Vector:  
0x1C0  
CAP Jumper JP1: Open  
Note ! If the default settings above are what you desire and good for the  
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.  
Smartio C168H/HS User’s Manual 2-1  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Now you should do either the normal hardware installation (detailed in the later  
section, “Hardware Installation with IO-IRQ Utility”) or the quick hardware  
installation (detailed right in the next section, “Quick Hardware Installation”). The  
latter is provided to facilitate the hardware installation, only under the  
circumstances that:  
u
u
u
Only one Sma rtio C168 Series board is allowed to install in a system.  
Windows NT and 95/98 are the only operating systems supported.  
I/O address 0xA700 must be free  
Quick Hardware Installation  
To fully utilize the superior feature of flexible hardware configuration design of the  
Smartio C168 Series, a quick and easy method of installation is designed for users,  
which absolutely free the users from hardware configuration effort, i.e., installation  
without running configuration program: Io-irq.exe. Simply always short the  
jumper JP1. The software and hardware configuration will be completed at the same  
time while doing the software configuration.  
Besides, the speed range will be set to from 50 to 921.6K bps by default, which is  
called High Speed Spectrum and detailed in the section, “Hardware Installation  
with IO-IRQ Utility”.  
How to Do Quick Hardware Installation  
Users who install only one Sma rtio C168 Series 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  
2-2 Smartio C168H/HS User’s Manual  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Hardware Installation  
software configuration program will automatically update the hardware settings.  
After this, users already complete the whole installation.  
4. Shutdown System (Windows NT/95/98).  
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 cold start the system every time the  
configuration changed.  
Hardware Installation with IO-IRQ Utility  
This section is for those who can not use quick hardware installation:  
u
u
Install two or more Smartio C168 Series boards in a system.  
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.  
Before proceeding the software installation, detailed in the next chapter, “Software  
Installation”, do hardware configuration to setup the I/O address and IRQ with  
“Io-irq.exe”, detailed in the next section.  
Remember to keep the hardware settings in mind for the software installation.  
The Smartio C168 Series has the following default (factory) settings:  
I/O address : 0x180 (Port 1), 0x188 (Port 2), 0x190 (Port 3), 0x198 (Port 4)  
0x1A0 (Port 5), 0x1A8 (Port 6), 0x1B0 (Port 7), 0x1B8 (Port 8)  
IRQ :  
10  
INT Vector : 0x1C0  
Smartio C168H/HS User’s Manual 2-3  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Because the ASIC-designed Smartio C168 Series has no switch and no jumper for  
configuring manually the I/O address, IRQ, INT vector, etc. of the boards, you must  
run the software utility, Io-irq.exe, in the driver diskette under DOS system to  
change the hardware configuration.  
1. Choose a PC that has DOS system inside.  
2. Power off the PC.  
3. Make sure no hardware conflict and plug the board in a free 16-bit slot of the PC,  
one board at a time with JP1 open.  
+ 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.  
The Smartio C168 Series has the following default (factory) settings,  
I/O address: 0x180 (Port 1), 0x188 (Port 2), 0x190 (Port 3), 0x198 (Port4)  
0x1A0 (Port 5), 0x1A8 (Port 6), 0x1B0 (Port 7), 0x1B8 (Port 8)  
IRQ:  
10  
INT Vector: 0x1C0  
Configuration Access Port (CAP): 0x180  
4. Power on the PC and enter into DOS system.  
5. Run the utility “Io-irq.exe” contained in the driver diskette to set up I/O address,  
IRQ and INT vector of the board. Please refer to the next section, “IO-IRQ  
Utility and Hardware Configuration” for more details. Or follow the on-line help  
to configure the Smartio C168 Series board.  
After completing the hardware configuration, the board is ready for use under  
operating systems, such as Windows NT and 95/98, DOS, UNIX etc.  
IO-IRQ Utility and Hardware Configuration  
Note that the CAP address, e.g. 0x180, is identical to the first port's I/O address  
except in one case that the JP1 jumper is installed before powering on the PC. In  
this case, the CAP address will be forced to 0xA700. The CAP address must be  
2-4 Smartio C168H/HS User’s Manual  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Hardware Installation  
typed correctly. With the correct CAP address, the utility can find the configuration  
stored in the on-board EEPROM and display it on the configuration panel. The  
CAP address is the only channel via which the configuration utility Io-irq.exe can  
access the board.  
1. Run the utility “Io-irq.exe” contained in the driver diskette to set up I/O address,  
IRQ and INT vector of the board.  
2. Select “Smartio/Industio ISA Family” and press ENTER key.

3. Enter the CAP address of the Smartio C168 Series board to be configured.  
4. Configure the following parameters as necessary.  
Port Index  
Indicate the port index for each port.  
I/O address Enter the base I/O address for each port, either sequentially or  
not. Avoid to conflicting with any other devices.  
IRQ  
Enter the IRQ, 2, 3, 4, 5, 7, 10, 11, 12 or 15, for each port,  
independently or not.  
Speed  
This field specifies the use of normal or high speed capability.  
Normal speed ranges from 50 bps to 115.2 Kbps. High speed  
ranges from 50 bps to 921.6 Kbps. Smartio C168 Series  
support both normal and high speed spectra.

Hardware Installation  
Note that, currently, port that uses MOXA Windows NT and  
95/98 driver will run at the displayed speed. To be clear, when  
Smartio C168 Series board is configured as High Speed  
Spectrum, any port driven by the Moxa-provided Windows  
NT and 95/98 driver will display the exact working speed. For  
example, the displayed speed 38.4 Kbps is equal to the working  
speed 38.4 Kbps.  
However, if the port is driven by NON Moxa-provided driver,  
such as standard serial driver, or Moxa drivers other than  
Windows NT and 95/98, such as DOS, the real working speed  
is equal to 8 times of the displayed speed. For example, a port,  
if set to Normal Speed Spectrum with 38.4 Kbps, will work at  
38.4 Kbps for sure; while a port, if set to High Speed Spectrum  
with displayed speed 38.4 Kbps, will actually work at 307.2  
Kbps (38.4 Kbps¡ 8Ñ).  
The following is the 8 times speed mapping list for quick  
reference purpose, particularly for DOS driver.

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 Smartio C168 Series 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.

Then the MOXA Multiport Board Installation Utility will show for  
board installation.  
Choose C168 Series driver and follow the instructions to install.  
Step 6. Configure the board by,  
# moxaadm  
The moxaadm utility is used to tell the UNIX driver how many Smatio  
C168 Series boards are installed, what their basic setting (I/O or IRQ), etc.  
It is also used to remove the Smartio C168 Series UNIX driver from the  
system. Whenever the setting is changed, run this utility again and tell the  
UNIX driver what is changed. Refer to section “Administration Utility-  
moxaadm” for more information.  
This utility is not intended to change the Smartio C168 Series  
“hardware” I/O address nor IRQ setting. If you need to change the  
Smartio C168 Series hardware IRQ, for example, you need to execute  
IO-IRQ utility under DOS environment. The IO-IRQ utility is contained  
in the Dos/Windows3.x driver diskette.  
Only up to two Smartio C168 Series boards are allowed to be installed  
under UNIX systems when MOXA UNIX driver is used.

Step 7. Now you may shutdown the system and reboot. If you have trouble in  
booting the new UNIX kernel, use the backup kernel (/unix.moxa or  
/stand/unix.moxa) to boot your system and the system will work as before.  
Refer to Chapter “Troubleshooting” for more information.  
After the system starts up again, the following successful messages will  
show:  
For SCO UNIX/OpenServer,  
“C168

For UNIX SVR4.2,  
“C168H board, base address 0x180, irq 5, Ver. x.x (high speed)”  
where high speed indicates the port is in high speed status; otherwise, in  
normal speed status.  
If the following error message appears:  
For SCO UNIX/OpenServer,  
“WARNING! C168 board IRQ at 11 mismatch (base address at 0x180)!”  
For UNIX SVR4.2,  
“WARNING! C168 board IRQ at 11 mismatch (base address at 0x180)!”  
indicates the IRQ of the port is different between hardware and software  
configurations. However, only this port is disabled. Other ports should  
still work.  
If the following common error message appears:  
“WARNING! C168 board base address at 0x180 not found!” or  
“WARNING! C168 board interrupt vector disabled (Board base =  
0x180 )!”, indicates the base address of the board is not found or interrupt  
vector of the board is disabled. In these cases, all ports will not work.

MOXA TTY Device Naming Convention  
If the Smartio C168 Series is successfully configured, there will be two tty devices  
created for each port at /dev directory: one is non-MODEM tty (e.g. ttye11), and  
the other is MODEM tty (e.g. ttyE11). The two devices are actually accessing the  
same physical port except that the MODEM tty has to check the ON status of DCD  
signal to be able to open device, and closing device automatically as DCD signal is  
OFF.  
The convention of the MOXA tty device name is /dev/tty{e-f}{1}{1-8}, where:  
"tty" + "A" + "B" + "C"  
Port ordinal number, 1-8  
Always 1  
Board ordinal number  
"e" or "E": 1st MOXA board  
"f" or "F": 2nd MOXA board  
Capitals indicate a MODEM port  
Standard tty device prefix  
For example:  
/dev/ttye11  
/dev/ttye12  
/dev/ttye13  
/dev/ttye14  
/dev/ttye15  
/dev/ttye16  
/dev/ttye17

Baud Rate Settings  
For Smartio C168 Series set to High Speed Spectrum, the real working speed,  
is exactly eight times of the speed displayed by “stty” command. A port, if set to  
Normal Speed Spectrum with 38.4 Kbps, will work at 38.4 Kbps for sure; while  
a port, if set to High Speed Spectrum with displayed speed 38.4 Kbps, will  
actually work at 307.2 Kbps (38.4 Kbps¡ 8Ñ).  
Note also that the 50 baud rate, B50, will no longer stand for 50 bps, instead, it  
means 57600 bps, and 75 baud rate, B75, for 115.2 Kbps. Furthermore, if the C168  
Family H Series board is set to High Speed Spectrum, the real working speed is 8  
times of the displayed speed. Hence, B50, 57.6 Kbps, is for 460.8 Kbps and B75,  
115.2 Kbps, is for 921.6 Kbps.  
Administration Utility – moxaadm  
Users can use the administration utility, moxaadm, to change the Smartio C168  
basic and advanced configuration, to monitor the ports' activity, to use terminal  
emulation and to remove the installed MOXA driver from the system.

Software Installation  
Basic Configuration  
In the [Basic configuration] dialog, users can set base I/O address and interrupt,  
which should be the same as the hardware configuration of the boards. Kernel  
rebuilding is required if any setting is changed.  
In [getty Setting] sub-dialog, there is one noticeable field:  
Non-Modem and Modem Baud Rate  
This field stands for the initial baud rate symbol and hunt sequence for Non-Modem  
/Modem tty. It is simply for setting parameters of getty entries in system file  
/etc/inittab which could also be manually modified by system administrator. Its  
value comes from the UNIX system “getty default” file, i.e., “/etc/gettydefs”. Modify  
this field to suit your need.  
In some cases, you may need to modify the “getty default” file as well. For example,  
in some UNIX systems, the “9600” symbol indicated 8-data-bit no-parity while in  
Smartio C168H/HS User’s Manual 3-29  
Download from Www.Somanuals.com. All Manuals Search And Download.  
others it may stand for 7-data-bit, even-parity. So, please examine the “getty  
default” file carefully, and make sure the terminal settings is the same. Otherwise,  
garbled data will be inevitable.  
Advanced Configuration  
In the [Advanced configuration] dialog, users can set baud rate mapping, Rx FIFO  
trigger level, Tx FIFO trigger level and RTS/CTS hardware flow control.  
Baud Rate Mapping  
There are two different baud rate tables can be selected: High Band and Low Band.  
The highest baud rate for High Band is 921.6K bps, while 38.4K bps for Low Band.  
Because of the limit of UNIX termio/termios definition, the highest baud rate label  
is B38400 (mapped to 38.4K bps). If users wish to use the baudrate higher than  
38.4K bps for MOXA boards, this baud rate will be re-mapped to the lower as  
defined in the below baudrate-mapping table:

Tx FIFO Trigger  
Tx FIFO sizes from 1 to 16 bytes are available, and the default value is 16 bytes.  
RTS/CTS Hardware Flow Control  
This feature is for more flexible driver behavior. If set to “Disable” (default), CTS  
signal is not needed for tty port to transfer data and RTS/CTS hardware flow control  
function in driver is disabled. On the contrary, if set to “Enable”, CTS signal is  
needed for tty port to transfer data and RTS/CTS hardware flow control function in  
driver is enabled.  
Port Monitoring  
This utility gives you a quick view about all the MOXA ports' activities. You can  
easily learn each port's total received/transmitted (Rx/Tx) character count since the  
time when the monitoring is started. Rx/Tx throughputs per second are also reported  
in interval basis (e.g. the last 5 seconds) and in average basis (since the time the  
monitoring is started). You can reset all ports' count by <HOME> key. <+> <->  
(plus/minus) keys to change the displaying time interval.  
Press Enter on the port, that cursor stay, to view the port's communication  
parameters, signal status, and input/output queue.

UNIX  
Programming the MOXA Ports  
The system calls that apply to standard tty port can also be applied to MOXA port  
since MOXA port conforms to UNIX tty standard. System calls are like open(),  
ioctl(), read(), write(), close(), etc. Please refer to your UNIX Programmer's  
Reference manual.  
However, these system services only provide limited functions and thus may not  
satisfy the sophisticated programmers' need. In order to meet the user's special  
purpose, MOXA supports extended services through ioctl() command, which are:  
1. MIBUFED  
2. MOBUFED  
3. MTCRTS  
4. MTCDTR  
(= 0x401) To get byte count in input buffer.  
(= 0x402) To get byte count in output buffer.  
(= 0x403) To control RTS output signal.  
(= 0x404) To control DTR output signal.  
5. MLOWATER (= 0x405) To set output buffer low water level.  
6. MSTATUS (= 0x407) To read modem line status (CTS/DSR/DCD).  
7.MHWFLOW (= 0x40e) To enable/disable the hardware flow control.  
The next Section details all the commands.  
Extended UNIX Ioctl() Commands  
The following lists the syntax of MOXA extended functions for both non-SVR4.x  
and SVR4.x UNIX. The variable moxa_fd is the returned file descriptor by open() a  
specific MOXA port. For example,  
int moxa_fd;  
moxa_fd = open(“/dev/ttye11”,O_RDWR);  
1. MIBUFED

5. MLOWATER  
Sometimes the application software may not be able to write any further data to the  
output buffer because of the output buffer being full. The application has to wait  
Smartio C168H/HS User’s Manual 4-9  
Download from Www.Somanuals.com. All Manuals Search And Download.  
until the output buffer has 'enough space' again. The criteria to tell if the output  
buffer has 'enough space' is whether the output buffer reached its 'low water' level.  
That is the output buffer will accept further data only when the 'low water' level is reached.  
If the 'low water' value is relatively small, you may find that the output buffer  
become empty before you write another block of data (this is quite possible because  
UNIX is time-sharing multitasking environment). This will result in discontinuous  
data transmission. In a timeout-sensitive application, e.g. facsimile (FAX)  
transmission, discontinuous data may falter the operation.  
The default 'low water' is 512 bytes. You can enlarge it but better not exceed one  
half of the output buffer. Each port's output buffer is 32K bytes.

7. MHWFLOW  
This function is used to enable/disable hardware flow control. The first open()  
function of a port will set the hardware flow control bits on or off depending on the  
[RTS/CTS Hardware Flow Control] configuration in mxadm. However, users  
might want to control the DTR or RTS signal on their will, thus the RTS flow  
control bit should be turned off (HWFLowControlOff) in order to take over the  
control of DTR or RTS signal via function MTCRTS or MTCDTR. MTCRTS and  
MTCDTR can be effective only after the RTS flow control bit of MHWFLOW is  
turned off.

Utilities  
There are two utilities available for DOS: Data Scope and Diagnose, which are  
detailed below.  
Data Scope  
The Data Scope, BIN\SCOPE.EXE, is a suite of utility programs that can help  
users with system troubleshooting and serial communication debugging.  
There are three major functions in Data Scope utility:  
1. The Data Scope utility offers transparent monitoring of serial communication lines  
and allows data to be streamed to disk storage for later analysis.  
2. The TTY terminal emulation utility allows user to view the signal status and  
transfer data interactively or files using ASCII, XMODEM, YMODEM,  
ZMODEM and KERMIT protocols.  
3. The Diagnostic test utility provides port connection test with two MOXA ports  
connected via a properly wired cable.

Serial Programming Tools  
Please see on-line help as running BIN\SCOPE.EXE for more usage and capability  
information.  
Diagnose  
The Diagnose, BIN\DIAGNOSE.EXE, is a utility that can help users to diagnose  
the hardware condition of each port of the selected board. See on-line help for more  
details.  
Before executing it, please remove the Moxa driver in advance via executing “Mx-  
drv/Q” if the Moxa driver is running in the background.  
RS-485 Programming for Opt8J  
If you intend to do RS-485 communication with Opt8J, please follow the RS-485  
programming guide below and also refer to Chapter “Connection Option (Opt8x)  
and Cable Wiring” for more Opt8J RS-485 operation details.  
The Opt8J supports only 2-wire half-duplex RS-485 communication. Data+/- pins  
are served for both data transmitting and receiving, depending on the RTS signal.  
The port switch of each port should be set to On position. The port is for  
transmitting data if RTS is asserted and for receiving data if RTS is not asserted.  
RTS scheme is suitable for any system, including Windows NT and Windows 95/98,  
DOS, or UNIX, that permits RTS control from application programs.

There are 2 solutions to control RS-485 2-wire transmission.  
Solution 1  
The following model is common in RS-485 2-wire transmission.  
sio_SetWriteTimeouts(port, 0); /* Set sio_write() into block mode if  
for Windows NT and Windows 95/98 */  
sio_RTS(port, 1);  
/* Turn on RTS signal. The RS-485  
port is ready for transmitting data. */  
/* Write 10 byte characters in "buff".  
The function blocks until last  
character transmitted */  
sio_write(port, buff, 10);  
sio_RTS(port, 0);  
/* Turn off RTS signal. The RS-485  
port is ready for receiving data. */  
/* Read 10 bytes */  
sio_read(port, buff, 10);  
Solution 2  
There is a dedicated RS-485 function in PComm or API-232 library. It  
integrates the above functions of solution 1 regarding sending data as one.  
sio_putb_x(port, buff, tick ); /*  
1. Turn on RTS and ready for  
transmitting data.  
2. Send data.  
3. Wait for tick time.  
4. Turn off RTS and ready for  
receiving data. */  
For more information on these functions, please refer to PComm library on-line Help  
file for Windows NT and Windows 95/98 or API-232.txt file for DOS, respectively  
.

RS-422/485 Impedance Matching  
For RS-422/485 serial communications, when an electrical signal travels through  
two different resistance junctions in a transmission line, the impedance mismatch  
will sometimes cause signal reflection. Signal reflection causes signal distortion,  
which in turn will contribute communication errors. The solution to this problem is  
to establish the same impedance at the line ends as in the line itself by terminating  
them with resistors.  
The value of the termination resistor should equal the characteristic impedance of  
the transmission line. The resistors should be added near the receiving side.

6 Troubleshooting  
Common Smartio C168 Series problems and possible solutions are listed below. If  
you still have problems, contact your dealer 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 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 PComm “Diagnostic” utility for Windows NT and  
Windows 95/98 is good for testing MOXA boards and port conditions. If  
Diagnostic reports error, replace the faulty components.  
Smartio C168H/HS User’s Manual 6-1  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Software Causes and Solutions:  
a. Smartio C168 Series 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, Pcomm  
“Terminal emulator” or “HyperTerminal” utilities are good for testing the  
COM ports.  
3. Why the DOS utility IQ-IRQ can not access Sma rtio C168 Series 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 4 for how to solve this 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 Smartio C168 Series board is not plugged in a right or good slot. Please  
plug the board in a good 16-bit ISA slot.  
d. The Smartio C168 Series board may malfunction. Please return for repair.  
If any existing board has the same I/O address as 0x180, the default CAP  
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.  
This will force the CAP address to 0xA700.  
b. Change or disable the existing board's I/O address.  
4. What to do if user forgets or does not know the Configuration Access Port  
(CAP) address of Sma rtio C168 Series?  
The Smartio C168 Series multiport boards are designed without jumper or  
switch, so the configuration is completed only by DOS utility Io-irq.exe.

Download from Www.Somanuals.com. All Manuals Search And Download.  
Troubleshooting  
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-  
irq.exe can access to the board.  
The following procedure instructs user to recover once the CAP is unknown.  
Step 1.  
Step 2.  
Power off the PC.  
OFF  
Install jumper onto the JP1 of the board.  
Install  
jumper  
JP1  
Step 3.  
Power on the PC.  
Now the CAP address of the board will  
be 0xA700.

Step 4.  
Step 5.  
Step 6.  
Step 7.  
Execute Io-irq under DOS environment.  
A:> Io-irq  
Enter CAP address 0xA700 to access the board.  
Enter the “Configuration Access Port” in HEX: A700  
The previous hardware configuration will be shown.  
Modify them if necessary. Remember the CAP address this time.  
Exit the IO-IRQ.

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 that the MOXA board is found, but the IRQ is conflicting with  
another adapter. Please make sure there is no conflict with other adapter’s IRQ.  
Check the BIOS IRQ settings first. Make sure that an IRQ is available.  
2. After the system reboots, the error message “Cannot find any configured  
MOXA Smartio/Industio Series board!” appears in the Event Log.

Troubleshooting  
a. Some partial decoded network board may interfere with our board. Please  
avoid from using 0x300 as I/O address for those network boards.  
b. Check hardware configuration of Smartio C168 Series board by IO-  
IRQ.EXE. Then make sure the hardware configuration, including I/O  
addresses for each port, Interrupt Vector, IRQ, is identical to that of the  
driver.  
c. The I/O addresses may conflict with other devices, please change another set  
of I/O address such as I/O:0x280, Interrupt Vector:0x2C0.  
d. The board(s) is not plugged properly. Please make sure the board is seated  
firmly in the expansion slot.  
e. The slot for plugging the board is defective.  
In this case, please try other slots until you find a good one.  
f. The board might be defective.  
3. The COM number of the Sma rtio C168 Series conflicts with others.  
The COM numbers of different boards happen to be the same. Try to change the  
COM number mappings.  
4. Windows NT system panic (blue screen).  
The possible reason is an IRQ or memory 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

c. The I/O addresses may conflict with other devices, please change another set  
of I/O address such as I/O:0x280, Interrupt Vector:0x2C0.  
d. The board(s) is not plugged properly. Please make sure the board is seated  
firmly in the expansion slot.  
e. The slot for plugging the board is defective.  
In this case, please try other slots until you find a good one.  
f. The board might be defective.  
DOS  
This section is specific for troubleshooting under DOS. For general problems and  
solutions, please see the previous section, “General Troubleshooting”.  
1. After executing SER-DRV.EXE, error message “None serial port found!”  
appears.  
a. Make sure you’re using the right driver.  
b. Check if the board is properly plugged into ISA/EISA bus slot.  
c. Check if the I/O address and IRQ settings in SETUP program are same as  
the settings on board.  
UNIX  
This section is specific for troubleshooting under UNIX. For general problems and  
solutions, please see the previous section, “General Troubleshooting”.  
1. Under UNIX, when respawning quite a few number of tty ports, the  
following error messages appear: “Time out table overflow”, “File table  
overflow”, “Region table overflow”.  
Software Cause and Solution:  
The above error messages imply that the system resources are exhausted. You  
should tune the kernel parameters to a larger value and rebuild the kernel to be able  
to accommodate the new configuration. Refer to UNIX system manual about how  
to tune the parameters and rebuild kernel.

Troubleshooting  
“Time out table overflow”:  
“File table overflow”:  
NCALL parameter too small.  
NFILE or NINODE parameter too small.  
NREGION or NPROC parameter too small.  
“Region table overflow”  
:
2. Under UNIXs, the newly rebuilt kernel could not boot.  
Software Causes and Solutions:  
The C168 driver might not be built into the new kernel correctly.  
a. Please use the last good kernel backup to boot again. The kernel backup in SCO  
UNIX is /unix.moxa while in UNIX SVR4.2 /stand/unix.moxa.  
b. Then remove the C168 driver. Refer.  
c. Re-install the C168 driver once more.

UART 16C550C  
The UART chip, 16C550C, is an intelligent asynchronous controller capable of  
supporting one full duplex channel that simultaneously transfers data at 921.6 Kbps.  
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.
