4.2 Preparation 
  (1)  Connect the AC Adapter and External Printer to the computer. 
(2)  The System Setup should be set to the factory setting values by executing the “SETUP UTILITY” which can be invoked by F2 key at the POST. 
If not, the messages and items of the diagnostic  test may not be displayed properly on the 
LCD. 
(3)  The serial port must be enabled in the “SETUP  UTILITY” in order to execute the “1st SERIAL 
PORT” test. 
(4)  Connect the serial loopback plug. 
(5)  In order to test the parallel port with Loopback Plug, disconnect the printer cable and connect  the parallel loopback plug with Power OFF. 
 
4.3 NOTICE 
  When “Enter password” is displayed, use “Pa ssword Skipping Plug” in order to skip the user 
password.  1)  Connect the parallel plug to the parallel port. 
2)  Connect the PS/2 mouse plug to the mouse port 
3)  Power on the computer. 
 
The wiring of the parallel plug is described below. 
Connect pins 2-5-6-8-11-13-15-18-19-20-21-22 -23 to Shield GND (PS/2 mouse plug pin3). 
Connect pins 3-4-7-9-10-12 to VC5 (PS/2 mouse plug pin4) with 4.7KW each. 
 
 
 
CAUTION 
The plug described above must be used for servicing purpose only. 
Do not use it for other than the above purpose  and ensure that it remains confidential. 
Using the plug enables the user to skip the pr evious password and disable the password.
