CAUTION :
TO REDUCE THE RISK OF FIRE OR SHOCK HAZARD, REFER INSTALLATION OF THIS
BOARD TO QUALIFIED SERVICE PERSONNEL.
Before installation

Check that the power of the AJ-DE77, AJ-DE77H or AJ-DE77D (hereafter referred to as the “Quick
Cutter” ) is OFF.
Remove the four screws securing the top panel of the
Quick Cutter, then remove the panel.
Installation
While referring to the figure on the right, first
disassemble the accessory terminal board, and then
use two screws to secure the board to the right side
of the jack panel and two screws to secure the blank
panel on the left side.
(In the case of the AJ-DE77D, the blank panel is not
attached because the SDI terminal board is already in
place on the left side.)
After installation, the panels should appear as shown
in the figure below.
Connect the red coaxial cable provided with the
board to the SDTI terminal board OUT and the black
coaxial cable to the SDTI terminal board IN.

interface connector at the bottom rear of the Quick Cutter and
remove the TRV interface board together with its metal clamp.
Installation
(AJ-DE77 only)
Remove the four screws securing the TRV interface board and metal clamp,
and replace the board with the accessory TRV interface board, then use the
four screws to secure the metal clamp.
(AJ-DE77 only)

After setting NTSC or PAL for the P4 pin of the accessory SDTI board as shown in the jumper setting
diagram, refer to the coaxial cable connection diagram and connect the coaxial cables. The connections
with the board should be made in the following order:
1Connect the coaxial cable (black) which was connected in step 7 to the S_IN1 connector on the SDTI
card provided with the unit.
2 Connect the coaxial cable (red) which was connected in step 7 to the S_OUT2 connector on the SDTI
board.
3 Connect the coaxial cable (yellow) provided with the unit to the REF_IN connector on the SDTI board.
Remove the 20-pin remote cable shown at right
from the Remote I/O board connector followed by
the 3 screws, then remove the board metal clamp
from the Quick Cutter unit.
(For AJ-DE77H and AJ-DE77D, also remove the 2
screws and the fan as shown in the diagram at
right. It is not necessary to remove the fan’s power
cable.)
Installation
Remove the cable and screw shown in the diagram at
right, then remove the X4PCI board from the slot.
Insert the accessory SDTI board into the slot which had
accommodated the X4PCI board, secure it using the
screw, and connect the cable that was disconnected
from the X4PCI board to the connector of the SDTI
board.
Connect one end of the coaxial cable (yellow), which was
connected in step 11, to the J7 connector on the TRV
interface board.

board.
Refer to the figure of the circuit board below to ensure that the ROMs are installed in the correct
direction.
Replace the ROM (IC235) from the VTR unit's F1 board with the ROM provided with the board.
Refer to the figure of the circuit board below to ensure that the ROM is installed in the correct direction.
Remove the 4 screws shown in the diagram at
right and the right metal fitting grip of the
Quick Cutter unit, then remove the F1 and F2
boards of the VTR unit.
Return the F1 and F2 boards removed in step 16 to their original positions, and use the four screws to
secure the right metal fitting grip which was removed in step 16 to the Quick Cutter unit. Secure the side
panels and the top panel using the screws by performing steps 2 and 3 in their reverse order.

Precautions for SDTI use
Specifications
- 7 -
≥Before handling the interface board and its ROMs, be absolutely sure to attach a grounding strap.
≥Recording operations cannot be performed unless the SDTI input signals are DVCPRO (25
Mbps) format 4x or 1x transfer signals.
≥Recording operations can be performed only when the video, audio and time code data of the
SDTI signals are all regular data in compliance with the DVCPRO (25 Mbps) format.
≥Before use, supply the external reference signal to the reference input connector on the Quick
Cutter unit.
≥When inserting or ejecting a tape from the Quick Cutter equipped VTR, there will be some noise
from the SDTI analog monitor output screen.
≥When using this interface board, be absolutely sure to read the instructions for Quick Cutter
application Ver 3.0 as well.
≥This interface board can be operated with the Quick Cutter Ver 3.0 or later.
However, since it may be necessary to update the version of the software program for the VTR
which contains Quick Cutter, consult your dealer.
