BRIEF DESCRIPTION OF THE BUILT-IN FEATURES

The MIO-500 board is equipped with two RS-232C serial ports, one parallel port, one FDD controller, one IDE hard disk interface and one game port. This board can be installed in an 16-bit open expansion slot for the IBM PC/AT or any 100% compatible computer. This chapter provides an overview for each built-in feature onboard.

Caution: Computer components are easily damaged by static electricity. Be careful to handle the MIO-500 all-in-one expansion board only by its edges. Do not touch any of the metal circuitry, especially the gold contacts, with your hands.

SERIAL PORTS
The built-in serial ports are RS-232C asynchronous serial communication ports that can be used with modems, serial printers, remote display terminals and other serial devices for asynchronous communication. You can select the interrupt channel IRQ2 to IRQS through jumper configuration. Included in the package is a 9-pin connector attached to a 9-pin cable and a metal bracket to mount the connector. The serial ports on your MIO-500 board uses the following system 0 ports:

The MIO-500 board adheres to the RS-232C engineering standards. The serial ports can be configured as DTE (Data Terminal Equipment) or as DCE (Data Communication Equipment) signal. You can set the serial port to run in either one of these two Modem Handshake signals: normal or forced true. The default setting is set at normal configuration.

CONNECTING THE SERIAL PORT CABLE
The primary serial port (COM-A) is already installed on the board. Install the secondary serial port into COM-B. Make sure that the colored edge of the cable is aligned to pin 1 of the COM-B connector. Refer to the figure below for the location of the COM-A and COM-B connectors onboard.

PARALLEL PORT
The MIO-500 board has a standard feature for interfacing your PC to ) ( a parallel printer. This port is completely compatible with the IBM PC/ AT and uses the same female DB25 connector as an IBM port.

The parallel printer port on your MIO-500 board uses the following system W/O ports:

FLOPPY DISK DRIVE CONTROLLER
The MIO-500 board is equipped with a built-in floppy disk controller MIO-500 BOARD that supports up to two standard type floppy disk drives. You can install any 360KB, 720KB, 1.2MB and 1.44MB 5.25/3.5-inch floppy disk drives.

CONNECTING THE FLOPPY DISK CONTROLLER CABLE

Step 1
Install the 34-pin header connector into the floppy disk connector on the MIO-500 board with the colored edge of the ribbon aligned to pin

Step 2
Install the other 34-pin header connector into the disk drive with the colored edge of the daisy chained ribbon cable aligned to pin 1 of the drive edge connector.

IDE HARD DISK INTERFACE
The MIO-500 board is able to interface two IDE (Integrated Drive Electronics) hard disk drives. An IDE drive is a hard disk drive with the controller electronics built into the disk assembly. The integration of the controller and the drive as a single unit increases both the reliability and performance by eliminating redundant circuitry.

Note: Co-existence of non-IDE drives is not supported.

Step 1 Install the 40-pin header connector into the hard disk connector on the MIO-500 board with the colored edge of the ribbon aligned to pin 1.

Step 2 Install the other 40-pin header connector into the disk drive with the colored edge of the daisy chained ribbon cable aligned to pin 1 of the drive edge connector.

Note: Refer to your disk drive owner’s manual for information about proper drive select switch settings.

ADDING A SECOND IDE HARD DRIVE
When using two IDE drives, one must be set as the master and the other drive as the slave. Follow the instructions provided by the drive manufacturer for setting the jumpers and/or switches on the drives. No changes are needed on the MIO-500 when adding a second hard drive.

We recommend that both IDE hard drives be from the same manufacturer. In a few cases, drives from two manufacturers will not function properly when used together. The problem lies in the two drives, not in the MIO-500.

PREPARING AN IDE DRIVE FOR USE
IDE disk drives are already low-level formatted, with errors entered, when shipped by the drive manufacturer. To use an IDE drive, you will need to enter the drive type (this information is provided by the drive manufacturer) into the system CMOS setup table. Then run FDISK and FORMAT provided with DOS.

Note: Do not run FDISK and FORMAT programs on a drive that has been prepared, or you may lose all programs and data stored on the drive.

GAME PORT
The MIO-500 board is equipped with a game port. You can use any IBM compatible joystick. Included in the package is a 15-pin game port cable. Install the game port as shown below.
