Hitachi SA200 User Manual

In Bi-directional mode, the parallel port allows both data input and 
output only.

In ECP mode, the parallel port uses Direct Memory Access (DMA) 
to transfer data in the background without using CPU resources. 
The parallel port operates in ECP mode when you load an 
Extended Capabilities Port device driver. Only ECP-aware 
peripherals support this mode. If you configure the Operation 
Mode option field in the BIOS Setup program as ECP, the 
application you are using must be ECP aware.

See “Advanced Menu” beginning on page 91 for more information 
on setting the printer operation mode.

You can attach an external pointing device such as a mouse or a 
graphics tablet to either the PS/2 port or the serial port. Refer to 
your pointing device’s documentation for information on which 
port to select.

Follow these instructions to connect an external pointing device:

Determine the type of interface (PS/2 or serial) required 
by your pointing device. Refer to the device’s operating 
manual for more information.

If the device requires a PS/2 interface, locate the 
external mouse (Mini-DIN) port at the rear of the laptop. 
Refer to Figure 3 on page 7. Connect the male connector 
of your device cable to the female PS/2 port on your 
laptop. If the device requires a serial interface, locate the 
9-pin connector at the rear of your laptop by opening the 
large panel. Refer to Figure 3 on page 7. Connect the 9-
pin female connector of your device cable to the 9-pin 
male serial port on your laptop.

When connecting a serial mouse, the system may 
require additional configuration activities or may ask 
you to reboot your system.
