SOFTWARE UPDATE Same as the FD-4, the FD-8 software can be updated through the SCSI port. This means that unscrewing and opening up the FD-8 top panel is not necessary to change the EPROMs. 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-8 updated software. 1. Updated software in a removable medium (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-8 software. 1. 2. 3. 4. IBM PC/AT 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-8 (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. Connect the removable type SCSI drive to the IBM PC/AT compatible computer SCSI port. Insert the diskette to the removable type SCSI drive and format it by the computer on which Windows 95/98 is running. Copy the updated software file to the removable type SCSI drive (diskette). Set the removable type SCSI drive ID to 0 ~ 5 and connect to the FD-8 SCSI port. Insert the diskette with updated software file. The FD-8 LCD display shows "No Disk", "Initial..", "name of drive (e.g. ZIP 100)" and "FD8MOT" in order and comes to a standstill at the display below. Memorize the displayed ROM version and date before updating the software. : blinking ? 6. Pressing the EXECUTE/YES key would start updating the software. The display shows "Loading!", "Writing!" and "Initial.." in order and automatically returns to the above condition again. Check the displayed ROM version and date if the software is correctly updated by comparing to the ones displayed in the above procedure 7. 7. Eject the diskette with updated software file by the press of STOP or EXIT/NO key and insert the diskette formatted by the FD-8. 8. Confirm the software version by the Service Mode. For details, please refer to the section "4-2. Flash ROM/CPU version". CAUTION: 1. The diskette in which the updated software file is copied must be formatted by IBM PC/AT computer, not by Macintosh. 2. If something wrong happens while updating the software (e.g. A blackout occurred while updating the software.), the FD-8 might not be able to boot up the system software inside the Flash ROM. In such a case, please refer to the section "4-8. Flash ROM" (page 17). 3. The SCSI ID to be connected to the FD-8 must be selected to 0 ~ 5. The SCSI ID "6" is used for backing up purpose exclusively. The SCSI ID "7" cannot be used by technical reasons. 11 FD-8 4. SERVICE MODE There are various optional modes available in the FD-8 Service Mode. Please utilize them when servicing the unit. 4-1. Putting FD-8 into Service Mode The way of putting the FD-8 into Service Mode is as follow. 1) Connect a SCSI device, insert the diskette formatted by the FD-8 and turn the power of SCSI device on. 2) After confirming that the access LED on the SCSI device is lit and then goes out, turn on the power of FD-8. 3) While holding down the STOP button and SHIFT key, press the SETUP key. As shown below, by rotating the jog dial C.W. or C.C.W., various optional modes will be displayed in addition to the general SETUP menus. In order to select a certain optional mode, press the EXECUTE/YES key while its menu is displayed. 12 FD-8 4-2. Flash ROM & CPU version : blinking This mode is used to check the Flash ROM and CPU versions currently installed in the unit.

W., the CPU version can be checked. : blinking The example on the left indicates that the CPU version is V2.00 and its programming date is August 4, 1998. 4-3. DA Test : blinking This mode tests the signal flow from the DATA INPUT jack to the D/A converter. A S/P DIF digital signal (Fs: 44.1kHz) must be input to the DATA INPUT jack to execute this test. Then, press the EXECUTE/YES key while "?" is blinking. If the FD-8 is in a normal condition, "44.1kHz" and "DIGITAL" will be lit solid. The odd (1, 3, 5, 7 and L) and even (2, 4, 6, 8 and R) channels indicate the left and right input level of S/P DIF digital signal fed to the DATA INPUT jack respectively. If the FD-8 is not in a normal condition, "DIGITAL" will blink and the bargraph meter will not indicate any level. 13 FD-8 4-4. Display/Button Test : blinking This mode tests if all the segments on the LCD display, LEDs and buttons (switches) on the FD-8 top panel are correctly working or not. To execute this test, press the EXECUTE/YES key while "?" is blinking. If the FD-8 is in a normal condition, all the segments on the LCD display will be lit solid and all the LEDs on the top panel will start blinking. ? If the FD-8 is not in a normal condition, faulty segments on the LCD display and/or LEDs on the top panel will remain unlit. In this condition, if the EXECUTE/YES key is pressed one more time, the Button Test can be executed. The Button Test checks if each key/button and jog dial are working properly or not. The display on the left indicates that the RECORD button is pressed and held down. ("K" stands for the Key and "J" the Jog dial.) The display on the left indicates the condition when the jog dial is turned C.W. The table below shows the relationship between the key/ button/jog dial and the corresponding numbers appear on the LCD display. In order to quit the Button Test, turn the jog dial C.W. or C.C.W. further after "J_20" or "J-19" is displayed respectively.

Self Check : blinking This mode automatically tests the following points in order. · SCSI bus · ATA (E-IDE) bus · MIDI in/out circuit · S/P DIF digital signal (44.1kHz) · Vari-pitch circuit · A/D and D/A circuit (Input Monitor) CAUTION: In order not to form a MIDI signal loop, connect the MIDI cable after putting the FD8 into the Service Mode. To start the Self Check mode, press the EXECUTE/YES key when "?" is blinking. As shown in the left, "SelfCheck", "CurrentDr", name of connected SCSI drive (The example on the left shows that the Magneto Optical drive MOS350 is connected to the FD8 SCSI port.) and "ATA Bus C (check)" appear on the FD8 LCD display in order. If a 2.5" internal E-IDE hard disk drive is not installed in the FD-8, the Self Check mode comes to a standstill at "ATA Bus C (check)" test. In order to continue the Self Check mode, press the EXECUTE/YES key again. Continue to next page 15 FD-8 From previous page If the FD-8 is in a good condition, "Check OK!" will be displayed and the FD-8 is automatically put into Input Monitor mode with all the RECORD TRACK LEDs and RECORD LED flashing. In this condition, if a signal is applied to the FD-8 RECORDER IN (L, R) jacks, its level can be monitored on the bargraph level meter. To quit the Self Check mode, press the EXIT/NO key when "Check OK!" is displayed. The followings are examples of error message when the FD-8 is not working properly. · SCSI function · MIDI function · Digital Signal in/out (Fs: 44.1kHz) · Vari-pitch function 4-6. Offset Display : blinking This mode determines if the offset value against a master machine should be displayed or not when the FD-8 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. to change the display to "ON" and press the EXECUTE/YES key. In order to display the offset value, select the "MTC" time base 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. This is caused by the difference of internal clock between master and slave machines, which is running independently. 2. The two-digit numbers displayed in the right of percentage display ("05" in the left example) is only for software programming purpose. 16 FD-8 4-7. Initializing Disk : blinking This mode initializes an external SCSI device connected to the SCSI port or a 2.5" E-IDE hard disk drive internally installed. The disk drive currently connected can be initialized. CAUTION: 1. If both the external SCSI drive and the internal 2.5" EIDE hard disk drive are connected at the same time, the SCSI drive is given priority over the 2.5" E-IDE hard disk drive and is recognized by the FD-8. 2. Up to 2 x SCSI drives can be connected to the FD-8. One is for recording / reproducing (SCSI ID: 0 ~ 5) and the other for exclusive backing up (SCSI ID: 6). Initializing is possible on the SCSI drive (ID: 0 ~ 5) used for recording / reproducing only. After pressing the EXECUTE/YES key, "SURE?" will start blinking in the LCD display. In this condition, pressing the EXECUTE/YES key one more time would initialize the recognized disk drive. This mode puts the disk back to the condition originally formatted. : blinking ? 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-8 software inside the Flash ROM can be updated through the SCSI port. However, if something wrong happens when updating the software (e.g. A blackout occurred while updating the software.), the FD-8 might not be able to boot up by the system software inside the Flash ROM. 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-8. In this condition, the FD-8 is booted up using the system software inside the EPROMs. The next procedures to take are as follows. 1. Put the FD-8 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-8 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. 17 FD-8 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-8 or the internal E-IDE hard disk drive. (As mentioned before, the SCSI drive has a priority unless the SCSI ID is set to "6".) If the Free Block indicates a large number even after formatting and no signal is recorded or recorded signals are frequently skipped, the diskette / hard disk drive can be judged to be in a bad condition. 4-11. Test 1 : blinking This Service Mode is exclusively designed for software programming purpose. There is nothing to do with servicing / repairing the FD-8. 18 FD-8 5. ERROR CODE LIST The chart below indicates the error code number and corresponding description.
