The console pcb contains an LCD (Liquid Crystal Display), three LED
(Light Emitting Diode) control lamps, and the Print button switch. It also
serves as a connection point between the keyboard and the I
CPU board.
The display has 2 × 16 character with a 5 × 7 dots matrix and background
light. 8 characters are programmable.
The left-hand LED control lamp (marked "Power") shines green when the
power is on. Power on is also indicated by the display's background light.
The other two LEDs are programmable using the Fingerprint instructions
LED ON and LED OFF. The center LED (marked "Ready") is green and
blinks when data are received. The right-hand LED (marked "Error") is
red.
The console pcb is connected to J50 at the front of the CPU board via a
permanently fi tted 10-p fl at cable. This cable must be disconnected from
the CPU board before the cover can be entirely removed. There are also
two connectors (P2 and P3) for the cables from the keyboard.
When removing the console pcb, the locking washers must be cut apart.
