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.
Î
SPP
(D
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.
Î
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.
Î
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.
Î
ECP+EPP
The parallel port will be compatible with both ECP and
EPP devices
Î
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.
