SOFTWARE UPDATEThe FD-4 software can be updated through SCSI port. This means that unscrewing and opening up the FD-4 top panel is notnecessary to change the EPROMs on the MAIN PCB assy. Please refer to the following explanation for correct softwareupdating procedures.Updated software in a removable media (e.g. floppy disk, zip disk, etc.) to be sent via airmailUpdated software as an attachment file to be sent via E-mailThere are two ways of sending the FD-4 updated software.3-1. Method of Sending Software from Fostex Japan1.2.3-2. Required ToolsIBM PC compatible computer with SCSI boardRemovable type SCSI driveCable between the removable type SCSI drive and the SCSI boardCable between the removable type SCSI drive and the FD-4 (D-SUB 25-pin)The following tools/equipment are required to update the FD-4 software.3-3.
