DIAGNOSTIC TESTING OF THE PARALLEL PORT
|
||
|
||
|
||
In order to perform a thorough test of AST's parallel port (when
|
||
running IBM diagnostics) you need to provide the incoming signals
|
||
to the port. This may be accomplished by constructing a wrap
|
||
plug and installing it on the parallel port connector. To
|
||
construct a wrap plug use a DB25 male connector. Utilizing a
|
||
minimum of 30AWG wire make connections as listed below:
|
||
|
||
1 > 13
|
||
|
||
2 > 15
|
||
|
||
10 > 16
|
||
|
||
11 > 17
|
||
|
||
12 > 14
