Chapter 6: Replacing Assemblies

1680A,AD-series disassembly/assembly

To remove the CD-ROM drive assembly

1Do the procedure "To remove the chassis from the sleeve".

2Disconnect the IEEE 1394 cable from the PCI IEEE 1394 interface board. Disengage the cable from the cable clamps on the top of the CD-ROM drive assembly.

3Remove the data cable, power cable and audio cable from the CD-ROM drive interface board.

4Using a Torx T-10 screwdriver, remove five screws that secure the CD- ROM drive assembly to the chassis.

5Slide the CD-ROM assembly out of the chassis.

Remove the CD-ROM from the assembly

11 Using a Torx T-10 screwdriver, remove two screws that secure the CD- ROM interface board to the CD-ROM drive brackets.

2Remove the interface board from the CD-ROM drive brackets.

A connector on the back of the CD-ROM interface board will disengage from an interface connector on the rear of the CD-ROM drive.

3Using a Torx T-10 screwdriver, remove two screws, one on each side of the CD-ROM drive brackets, that secure the top bracket to the bottom bracket. Separate the two brackets.

Two 9-channel comparators interpret the incoming data and clock signals as either high or low, depending on where the user-programmable threshold is set. The threshold voltage of each pod is individually programmed, and the voltage selected applies to the clock channel as well as the data channels of each pod A field programmable gate array FPGA bridges the 1394 interface to the rest of the acquisition board components.
