VMIC VMIVME-7455 IDE CD-ROM Module

Module Feature

VMIVME-7455 is a single-slot 6U VMEbus IDE CD-ROM module developed by VMIC,designed to add removable optical media storage inside standard VME chassis. It integrates slim IDE CD-ROM unit,supports reading CD-ROM,CD-R and CD-RW discs for system booting,software installation,firmware download and offline data archiving for VME CPU boards. IDE signals are transmitted through VME P2 rear connector via 64-conductor flat ribbon cable to pair with compatible VMIC VME CPU boards such as VMIVME-7589 / VMIVME-7589A / VMIVME-7696. VME bus interface works as VME slave module,A16/A24 addressing and D08/D16/D32 data transfer supported. Front panel has CD eject button and activity indicator LED. Rugged Eurocard PCB with conformal coating,shock and vibration screened for power plant cabinet environment,widely used in gas/steam turbine VME control system maintenance,aerospace ground test bench and industrial VME computer chassis.

Working principle

VME host CPU sends IDE read commands over P2 backplane cable to VMIVME-7455. Onboard IDE interface chip forwards command to built-in CD-ROM drive to read optical disc data. Raw disc data is transmitted back to VME CPU through IDE and P2 path. Front panel LED shows drive read/write activity status. VME FPGA completes address decoding and IDE signal buffering. Power monitoring circuit protects optical drive against voltage surge.

Installation

Follow ESD safety procedure before handling.Fully power off VME chassis.Insert VMIVME-7455 into vacant 6U VME slot and lock front panel ejector latches.Connect 64-pin IDE ribbon cable between P2 connector of this module and paired VME CPU board.Power on chassis,load OS CD driver,run disc read test before commissioning.

Interface

VME J1/J2 backplane connector,P2 rear IDE signal pins,front panel CD slot and eject button.

Diagnostic

Board undetected: poor VME backplane contact,damaged edge connector or incorrect P2 cable wiring. Disc cannot be read: scratched optical disc,dirty lens or loose IDE ribbon cable. No drive activity: missing +5 V supply or IDE bridge chip failure. Eject malfunction: mechanical jam of CD-ROM mechanism.
