4.4.10.2 Printer Interface Board (061-1300-00)
This board is Fujitsu model FTP-622DCL001. The parallel interface printer data ar-
rives at CN1. The power comes in CN10. The printer head plugs into CN8. The head
up and paper out switches plug into CN3. The stepper motor plugs into CN13.
Note: There is no schematic for this board.
4.4.10.3 Printer Mechanism
The printer mechanism is high-speed line thermal printer, Fujitsu model FTP-
642MCL001 which contains a thermal head, a stepper motor, decelerating gears, a
rubber roller (platen), paper feed knob, head-up lever and 3 connectors: 16-pin head
connector, 4-pin stepper motor connector and 5 pin sensor connector. The rated
speed of this printer is 80 mm per second. The effective printing width is 104 mm,
with 832 dots per line and a 0.125 mm dot pitch.
4.4.11 Misc Circuits
4.4.11.1 Daughter Board Schematic (061-0171-0x)
Page 1: J1 is the JTAG interface to U1-A which is only used for software devel-
opment. Y1 is the 32KHz crystal for U1-A.
Page 6: J6 is the JTAG interface used to program the CPLD U5-C.
4.4.11.2 Connector Board Schematic (061-x172-0x)
Page 2: The Line inputs come in J1 pins 2 and 5. U2-A and U2-B re-reference
the Left signal ground from Chassis to AREF which is the Analog ground
on the Daughterboard. U6-A and U6-B do the same for the Right chan-
nel. The Voice Microphone signal comes in J2 pin 5T. U1-A and U1-B
re-reference the ground as with the Line Inputs.
4.4.11.3 Chamber Board Schematic (061-x178-0x)
Page 1: J1 is the JTAG interface to U1-A which is only used for software devel-
opment. Y1 is the 32KHz crystal for U1-A. The Dallas Interface origi-
nates on U1-A pin 53.
Page 3: The Dallas interface from U1-A on page 1 is sent out J7 pin 5.
4.4.11.4 Probeboard schematic (061-0177-0x)
Page 1: J1 is the JTAG interface to U1-A which is only used for software devel-
opment. Y1 is the 32KHz crystal for U1-A.
