(4) Power supply to SCSI terminating resistor
If the power for the terminating resistor is supplied from the drive to other SCSI
devices through the SCSI bus, the current-carrying capacity of the +5 VDC power
supply line to the optical disk drive must be designed with consideration of an
increase of up to 900 mA.
Select a method of power supply to the drive in accordance with the setting
terminal of the optical disk drive. See Subsection 4.3.3.
(5) Noise filter
To eliminate AC line noise, a noise filter should be installed at the AC input
terminal on the power supply unit of the drive. The noise filter specifications are
as follows:
Attenuation: 40 dB or more at 10 MHz
Circuit configuration: The T-configuration shown in Figure 3.12.
