[PAUSE]KEY:END DISPLAY

[Content] The Centronics port is checked by connecting a special connector which connects

the Centronics port output and input signal wires to each other, to the Centronics
port of the PRT board. Whether the input signal is turned ON/OFF or not is
checked by turning the output signal ON/OFF. Checking is repeated 10 times. If
there is no error, OK is displayed; if there is any error, NG is displayed.

rent Centronics timing is displayed and a new setting can be entered.
The Centronics mode setting is specified by IEEE1284.

The 2500 ns/500 ns adjustment values are adjusted for the minimum delay time
specified by IEEE1284.

2500 ns adjustment value (default value: 63)

0-127

500 ns adjustment value (default value: 13)

0-127

Normally set to the default and no need to change.
Some personal computers use a limited control method of Centro
communication, and the Centro communication method used in the
AR-5132 may not function. In such a case, change this setting to change the
Centro communication method according to the limited control method.

When the setting is changed, the newly set content becomes effective after termination of
the simulation mode.
