These options are used to select the port address for specific on-board serial port. The options

are 3F8H, 2F8H, 3E8H, 2E8H, Auto and Disable. Port 1 is COM1, Port 2 is Com2 and so on.

The operating mode of COM2/COM3 can be selected through jumpers on the embedded board.

Î UART Mode Select [Normal]

This option allows you to select the Infrared transmission mode. Normal is disabled. Operation

in the ASKIR mode is comparatively slower.

When a mode is selected the following IR transmission options will become available:

1. RxD, TxD Active [Hi, Lo]

2. IR Transmission Delay [Enabled]

3. UR2 Duplex Mode [Half]

4. Use IR Pins [IR-Rx2Tx2]

Î Onboard Parallel Port [378/IRQ7]

These options are used to select the port address for specific on-board serial port. The options

are 378/IRQ7, 278/IRQ5, 3BC/IRQ7, and Disable.

SPP

EFAULT) The parallel port will operate in the standard parallel

port (SPP) mode. This parallel port mode will work with

most parallel port devices but is slow.

EPP

The parallel port will operate in the enhanced parallel

port mode (EPP). The EPP mode supports bi-

directional communication between the system and the

parallel port device and the transmission rates between

the two are much faster than the SPP mode.

ECP

The parallel port will operate in the extended

capabilities port (ECP) mode. The ECP mode supports

bi-directional communication between the system and

the parallel port device and the transmission rates

between the two are much faster than the SPP mode.

ECP+EPP

The parallel port will be compatible with both ECP and

EPP devices

Normal

Î Parallel Port Mode [SPP]

These options are used to select the parallel port operating mode. The options are SPP, EPP,

ECP, ECP+EPP, and Normal. Two specific options avail when either of the ECP or EPP modes

is selected: EPP Mode Select and ECP Mode Use DMA.
