3. SOFTWARE UPDATE
The FD-4 software can be updated through SCSI port. This means that unscrewing and opening up the FD-4 top panel is not necessary to change the EPROMs on the MAIN PCB assy. Please refer to the following explanation for correct software updating procedures.

3-1. Method of Sending Software from Fostex Japan
There are two ways of sending the FD-4 updated software. 1. Updated software in a removable media (e.g. floppy disk, zip disk, etc.) to be sent via airmail 2. Updated software as an attachment file to be sent via E-mail

3-2. Required Tools
The following tools/equipment are required to update the FD-4 software. 1. 2. 3. 4. IBM PC compatible computer with SCSI board Removable type SCSI drive Cable between the removable type SCSI drive and the SCSI board Cable between the removable type SCSI drive and the FD-4 (D-SUB 25-pin)

3-3. Software Updating Procedures
Presuming that the updated software is correctly sent and is copied into your computer. 1. 2. 3. 4. 5. 6. 7. Connect the removable type SCSI drive to the SCSI board. Insert the diskette to the removable type SCSI drive and format it by the computer (IBM PC format). Copy the updated software file to the removable type SCSI drive (diskette). Reconnect the removable type SCSI drive to the FD-4 SCSI port. In order to boot up the FD-4 system software, insert the diskette formatted by the FD-4. Eject the diskette by pressing the EXIT/NO key while holding down the SHIFT key. Insert the diskette with updated software file. The FD-4 LCD display shows "No Disk", "Initial..", "name of drive (e.g. ZIP 100)" and "FD4MOT" in order and comes to a standstill at the display below.

SURE ?
SYNC OUT AUTO DRIVE SCSI A.PUNCH

8. Pressing the EXECUTE/YES key would update the software. The display shows "Loading!", "Writing!" and "Initial.." in order and automatically returns to the above condition again. This indicates that updating the software is completed. 9. Eject the diskette with updated software file and insert the diskette formatted by the FD-4. 10. Check the software version by the Service Mode. (For details, please refer to the section "4-2. Software/CPU version".)

CAUTION:
1. The diskette in which the updated software file is copied must be formatted by IBM PC computer, not by Macintosh. 2. If something wrong happens while updating the software (e.g. A blackout occurred while updating the software.), the FD-4 might not be able to boot up the system software inside the Flash ROM. In this case, please refer to the section "48. Flash ROM" (page 17).

4-6. Offset Display
: Blinking

This mode determines if the offset value against a master machine should be displayed or not when the FD-4 is working as a slave machine. If you would like to turn ON the offset display, press the EXECUTE/YES key while "?" is blinking. (The default setting is "off".) Then, turn the jog dial C.W and press the EXECUTE/YES key. In order to display the offset value, select the "MTC" by the TIME BASE key and the "REMAINING TIME" as DISP SEL key. CAUTION: 1. There might be a case that the percentage display does not indicate "0.0%" exactly when the FD-4 is working as a slave machine and is synchronizing with a master machine. This is caused by a difference of internal clock between both machines but there is nothing wrong with it. 2. The two-digit numbers displayed in the right of percentage display ("05" in the left example) is only for software programming purpose.

4-8. Flash ROM
: Blinking

This mode is used when copying the system software from EPROMs to Flash ROM. As mentioned in the section "SOFTWARE UPDATE", the FD-4 software inside the Flash ROM can be updated through SCSI port. However, if something wrong happens when updating the software (e.g. A blackout occurred while updating the software.), the FD-4 might not be able to boot up the system software inside the Flash ROM.

SYNC OUT CLK AUTO

DRIVE SCSI A.PUNCH

In this case, the following procedures must be taken. 1. 2. 3. 4. Turn the switch S1 on the MAIN PCB assy to "EPROM" side. Mount and solder the EPROM sockets to "U31" and "U32" on the MAIN PCB assy. Plug the EPROMs into the sockets. Turn on the power of FD-4.

In this condition, the FD-4 is booted up using the system software inside the EPROMs. The next procedures to take are as follows. 1. Put the FD-4 into the Service Mode, select "FlashROM" and press EXECUTE/YES key. ("SURE?" is blinking.) 2. Press the EXECUTE/YES key one more time to copy the system software from EPROMs to Flash ROM. 3. Turn the switch S1 to "FLMEM" side. 4. In order to confirm that the FD-4 is booted up using the system software inside the Flash ROM, turn off the power, disconnect the EPROMs and turn the power back on again. 5. After the confirmation, update the system software inside the Flash ROM through SCSI port again.

4-9. Event Number
Individual Audio Files are continuously recorded in each track of program on the FD-4. However, the FD-4 disk management system allows to create a "no signal recorded" section between Audio Files. This "no signal recorded" section is handled as "Zero File". As shown in the diagram below, Audio Files and Zero Files will be alternately recorded on the FD-4 and each Audio File and Zero File are counted as individual "Event". Thus, the number of events on a certain track is calculated by summing up these Audio Files and Zero Files. Each track can accommodate up to 512 events but the FD-4 will not newly record events when the number of events reach 508.

CAUTION: If a long recording and/or many editing is committed, the Event Number increases. If the Event Number is getting closer to its maximum limit (508), please save/load the data to/from an external DAT recorder or SCSI device. During save/load procedures, Audio Files can be optimized and as a result, the Event Number decreases.

4-10. Free Block Check
: Blinking

This mode is used to check the condition of the diskette inserted into an external SCSI drive connected to the FD-4. If the Free Block indicates a large number even after formatting the diskette and no signal is recorded, the diskette can be judged to be in a bad condition.

The chart below indicates the error code number and corresponding description. Since the error code list is basically designed for our engineers to improve the software, the description is quite technical. If you find the FD-4 with one of the error codes displayed, we encourage you to update the software first. In case updating the software does not solve the problem, we would like you to inform us about details.
