4 Replacing the V1 main board

All PC boards are very sensitive to ESD. Make sure you touch the V1 power supply before

any direct contact with the PC boards.

The V1 main board is also refered to as DVP100.

4.1 Removing the V1 Main Board

♦ Remove all cables from the back of the V1.

♦ Remove the V1 top cover.

♦ Remove the (4) screws from the S-VIDEO connectors.

♦ Remove the (4) screws from the MIDI connectors.

♦ Remove the (4) screws from the XLR connectors.

♦ Remove the (4) nuts from the BNC connectors.

♦ Remove the 7 screws holding the V1 main board to the chassis. Do not remove the power

supply. Write down the positions of those screws becuase they differ for each revision of the

main board.

♦ A Data-Express mounted on the V1 bracket should be removed to allow space for the main

board to go out. A Jaz drive can stay.

♦ Remove the old main board.

4.2 Installing the V1 Main Board

If the new board has a sticker blocking one or more of the holes, make sure it stays there

♦ If the new board is rev D or higher, remove the two nuts located on the DB9 connector J5.

♦ If the new board is revC or lower make sure the nuts are screwed to the DB9 connector J9.

♦ Install the new main board in place.

♦ Install the 7 screws that hold the main board to the chassis.

♦ Install all the screws and nuts on the back of the V1.

♦ Connect the 10 pin IDC connector to J6. Pin 1 (red mark on the cable) should be to the left if

looking at the front of the V1.

♦ Connect the 16pin IDC audio cable to J26. Pin 1 (red mark on the cable) should be to the right if

looking at the front of the V1.

♦ Connect the SCSI 50 pin IDC cable to J9. Pin 1 (red mark on the cable) should be to the right if

looking at the front of the V1.

♦ The IDC cable connection is very sensitive. Any wrong connection will cause severe damages to

the RCV-PCB board.

♦ If by mistake, the cables from the remote control board (RCV-PCB) were unplugged, they

should be connected back as follows:

-IDC10 cable to the IDC10 connector. Pin 1 (red mark on the cable) should be to your

right if you are looking at the front of the V1

-IDC16 cable to IDC16 connector. Pin 1 (red mark on the cable) should be towards

the top of the V1.

♦ Install all the screws on the back of the V1 .
