Driver Installation - Windows 3.1

Normally, serial and parallel I/O ports can be supported by Windows 3.1 default device drivers. However, there are only 4 serial ports (3F8h, 2F8h, 3E8h, 2E8h) and 3 parallel ports (3BCh, 378h, 278h) that are supported by default. Most likely, the ports added by this card will require manual port setting changes, however, it is important to determine the PCI serial and parallel port resources, prior to doing so:

[OS Platform] :

Microsoft Windows :V3.1/3.11

1. Run PCIDOS.exe (located on the Driver CD under \PCI IO\DOS\PCIDOS.exe) to display the following information:

On-Board/ISA Serial COM1 3f8H
On-Board/ISA Serial COM2 2f8H
PCI Serial COM3 b800H,IRQ 10
PCI Serial COM4 b808H,IRQ 10
On-Board/ISA Parallel LPT1 3bcH 

1. Make note of the information displayed in PCIDOS.exe.
2. Start Windows 3.1.

Instruction Manual

1. Change the port settings accordingly, based on the information displayed in Step 2, by entering Ports, located in Control Panel.
2. When asked if you wish to restart the computer, please select Restart Now.
3. To verify the PCI port settings, open \Windows\system.ini.

Instruction Manual

A note about remapping:

1. Since some PCI serial ports can support the remapping function (4025D/4027D/4028D/4036D/4037D/4038D/4079D/E/F), please check the PCI card using the SunixPCI.exe utility, located on the Driver CD.

Clock = 1.8432 MHz for remappable port

Item	Actual Baudrate BIOS/DOS setting Remark
1	92	1600 Does not support
2	46	0800 Does not support
3	23	0400 Does not support
4	11	5200 115200

9	48	00 4800
10	24	00 2400
11	12	00 1200
12	300	300

1. Since the PCI serial card is driven by a higher CLK (14.7456 MHz), the actual baud rate is 8 times higher than the BIOS/DOS baud rate setting. The below table illustrates the relationship:

Item	Actual Baudrate	BIOS/DOS setting	Remark

Configuration

Com Port Configuration - Windows 2000/XP

1. Enter the Device Manager utility, located in the Control Panel. The newly installed ports will be located under Ports (COM & LPT). Please locate and select the ports you wish to configure by right-clicking on the COM Port name, and selecting Properties.

1. Select Port Settings. Here, you will be able to configure Bits per second, Data bits, Parity, Stop bits and Flow control.

Instruction Manual

Please note: There are three kinds of flow control: Xon/Xoff, Hardware, and None. The Xon/Xoff selection uses a software protocol. Hardware indicates that the flow control is using RTS/CTS, however the RTS/CTS is controlled by software as well. None indicates that no flow control is present. Click the Advanced button, if you want to set more advanced features.

Com Port Configuration - Windows 95/98/98SE/ME

1. Enter the System Properties utility, located in the Control Panel. The newly installed ports will be located under Ports (COM & LPT). Please locate and select the ports you wish to configure by right-clicking on the COM Port name, and selecting Properties.

1. Select Port Settings. Here, you will be able to configure Bits per second, Data bits, Parity, Stop bits and Flow control.

Instruction Manual

Please note: There are three kinds of flow control: Xon/Xoff, Hardware, and None. The Xon/Xoff selection uses a software protocol. Hardware indicates that the flow control is using RTS/CTS, however the RTS/CTS is controlled by software as well. None indicates that no flow control is present. Click the Advanced button, if you want to set more advanced features.

1. Configure the Enable Auto CTS/RTS Flow Control, 16/32/64 bytes FIFO length and Receive/Transmit Buffer trigger level if necessary.

Enabling Auto CTS/RTS Flow Control means the CTS/RTS flow control is controlled by hardware automatically. The system will remain more stable if the function is enabled.

Setting the Receive/Transmit Buffer to a higher value will get faster performance, because the interrupts will be reduced, but the time for interrupt service routine will become shorter. The receive buffer overflow will occur if the CPU is incapable of handling the request. If you notice system instability, please reduce this setting to a lower value.

Com Port Configuration - Windows NT 4.0

1. Locate the Multi-I/O Card Configuration icon, located in the Control Panel.

Instruction Manual

1. Select PCI/ISA Serial Ports and select the serial port you wish to configure from the drop-down box. Press Setup to configure the serial port.

1. Set the 32 byte FIFO or Auto Flow Control or Recieve Trigger Level, and click OK. Please note: If you stall the modem using Auto Flow Control, please remove the checkmark from Auto Flow Control Enable.

LPT Port Configuration - Windows 95/98/98SE/ME

1. Please ensure that the desired parallel peripheral device is securely connected to the parallel port provided by PCI2S1PDVLP.
2. Enter My Computer and double-click on the Printers icon.
3. Double-click on the Add Printer icon and click Next.
4. Once the Add Printer Wizard appears, please click Next.

1. Install the drivers that were included with your printer at the time of purchase. If you want to connect the printer to the newly installed parallel port, please select PCI ECP/EPP port, and click Next.

Instruction Manual

1. If you wish to connect a scanner or zip disk to the newly installed port, you will need to remap the Parallel Port I/O address to 0x378 or 0x278. To do so:

a. Open System Properties.
b. Locate and double-click on Multi IO Controller, from within the Device Manager.
c. Select PCI Multi I/O Adapter by right-clicking on the listing, and click Properties.

1. Select the Configure tab. If you need to remap the I/O address, please select Remap to legacy 0x378 I/O port and/or Remap to legacy 0x278 I/O port. This setting will be saved once you click OK, and will take effect once the computer has been rebooted.

LPT Port Configuration - Windows NT 4.0

1. Double-click on the Multi I/O Card Configuration icon, located within the Control Panel.

Instruction Manual

1. Select PCI Parallel Ports to configure the I/O address of the parallel port. Select Remap to legacy 0x378 and/or 0x278, if you wish to remap to these addresses.
2. Click OK to confirm your selection. These settings will take effect upon rebooting the computer.

Please Note: The onboard parallel port is always set to LPT1, if the remap function is disabled. When the parallel port is remapped to 0x378 or 0x278, the onboard parallel port will become the last available LPT port.

Please Note: When you connect a scanner to the remapped parallel port, you must turn on the scanner prior to turning on the computer, for it to function properly.

LPT Port Configuration - Windows 3.1

Since Windows 3.1 only supports 3 parallel ports (3BCh, 378h, 278h), the PCI parallel ports can only be recognized if the DOS driver is activated in advance.

1. To activate the DOS driver, run PCIDOS.exe, located on the Driver CD under D:\PCI IO\DOS\PCIDOS.exe.

1. Install the printer in Control Panel

Click Connect

Instruction Manual

1. Select the parallel port you wish to use for the printer connection. For optimum compatibility, it is recommended that the onboard LPT1 is set to 3BCh.
