CyberResearch® CPU Cards

CPEx GX-333-X

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.

ÎUART 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]

ÎOnboard 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

(DEFAULT) 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

ÎNormalÎParallel 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.
