Fint forløb med levering af manualen. Kvaliteten af skanningen betegnes som middel
 ;
I found the manual to be clear concise and complete. It was of immense assistance when removing the unit as the unit was over 22 years old and the wiring diagram was unobtainable from the manufacturer. The exploded drawings were clear as were the instructions and labels.
;
I will highly recommend this seller. They are honest, accurate, fast and responsible.

This manual was very good & was very helpful with repairs.
Always great & fast service from Owner's manual.

Very pleased with the quality of the scan. No complaints whatsoever.
1-3. Circuit Operation
1-3. Circuit Operation
1-3-1. DVA-M1100
BF-77 board 1-bit serial signal and 27 MHz clock signal that are supplied from the DVA-MC1100 at the TTL level are buffered by the BF-77 board and are sent to IC181 of the MB-75 board via TP185 and TP186 of the MB-75 board.
1-3-2. DVA-MC1100
IF-747 board MPU (IC3) communicates with the DVA-M1100 via the remote connector (CN2) using RS-232C. It controls the HDD that is connected to the SCSI connector (CN3) via the SCSI controller (IC12) and reads data from the HDD. DMA (IC8) writes data that is read from the SCSI connector, into DRAM (IC11). It also reads data from DRAM and converts the data from parallel to serial in synchronization with the 27 MHz clock. The IF-747 board sends the converted 1-bit serial signal to the DVA-M1100 together with the 27 MHz clock signal via the remote connector (CN2) at the TTL level.
