Technician’s Guide 2-8
Plus board and the Applicator Board. The assembly contains a linear regulator, mounted to a
heat sink, that provides the Applicator Board with 24 Vdc.
The J1 connector, on the Regulator Assembly, is connected to the J10 connector on the Prodigy
Plus board through the Power cable (6105-272). Pin 1, on the J1 connector, is connected to
digital ground (DGND). Pin 2 is connected directly to 5.0 Vdc. Pin 3 receives the 33 Vdc +/- 3
volts from the Prodigy Plus board and pin 4 is connected directly to analog ground (AGND).
The J2 connector provides the regulated output voltage of 24 Vdc to the Applicator Board. Pin
1, on the J2 connector, is digital ground (DGND). Pin 2 is connected directly to 5.0 Vdc. Pin 3
provides the regulated 24 Vdc to the Applicator Board and pin 4 is connected to analog ground
(AGND). Pins 5 and 6 are not used. The Regulator Power cable (6105-405) connects to the J2
connector on the Regulator Assembly and it also connects to the J3 connector on the Applicator
Board.
HAND-HELD TERMINAL (6105-260)
The Hand-Held Terminal (6105-260) is used to setup the programmable options on the
PA/4000. It connects to the Connector Board through the Hand-Held Terminal cable (6105-
144). The Applicator Board communicates to the Hand-Held Terminal via an RS232 type
protocol scheme. The Hand-Held Terminal cable connects to the Hand-Held Terminal at the J3
connector.
The J3 connector, on the Hand-Held Terminal, provides the signals to the Applicator Board via
the Connector Board. Pin 1, of the J3 connector, is connected directly to 5.0 Vdc. Pin 4 is
connected directly to digital ground (DGND). Pin 2 provides the Hand-Held Terminal with the
receive data signal from the Applicator Board. Pin 3 is the transmit data output signal from the
Hand-Held Terminal to the Applicator Board.
For more information about the programmable options of the Hand-Held Terminal, reference
section 4.0 of the User’s Manual contained in Section 1 of this manual.
PRODIGY PLUS BOARD (2801-027)
The PA/4000's control board contains the power supplies, CPU, memory, serial I/O, motor I/O
logic, and logic for supplying data to the printhead. The board is intensively controlled by
software and, except for correcting the obvious, it is most likely more economical to replace
than to repair the PA/4000's control board.
Since some components are easily identifiable and have straightforward uses, let's cover them
quickly. One nice design feature of the Prodigy Plus is that the chips are nearly all socketed.
Without knowing much about electronics, a service technician can easily make quick repairs if
needed or simple replacement of the entire board, which is often more economical.
