Jumper Settings for Connectors

Following is a brief explanation of the various functions of a control
panel that the PEM-2530 supports and some of the jumpers which may
be connected:
Keyboard Lock (Jumper J1)
Jumper J1 is used to enable the use of the keyboard and the power
LED. The keyboard lock is used to enable or disable the keyboard. By
disabling the keyboard, you can ensure that anyone who does not have
a key will be unable to use the computer. Unlocking the keylock
enables the keyboard.
Power LED (Jumper J1)
The power LED indicates whether the power is on. Refer to the figure
below for jumper J1 pinouts.

Hardware Reset (Jumper J2)
Jumper J2 is used to enable the hardware reset. The reset switch
restarts the computer from the RAM test stage. If you encounter any
problems while using unfamiliar software, you can always restart from
the beginning by pressing the reset button. Note, however that any
data which has not been saved to disk will be lost. Refer to the figure
below for jumper J2 pinouts.
