DECIDING ON SYSTEM
CONFIGURATION
Before installing or using the changer, the first thing which has to be done is to decide what components you should install to where of the changer.

If you wish to install three or more drives or to use more than one SCSI bus to increase data transfer speeds, it will be necessary to purchase additional connector panels and SCSI cables.
To determine what additional equipment must be purchased in order to create a desired configuration, it is recommended that you first decide where drives are to be installed and consult the configuration sheet on p. 225
226
Before actually beginning to configure your changer system, it is absolutely necessary that the following items be determined:
¶The types and numbers of drives to be installed and where they are to be installed. (An additional power unit is necessary when installing 9 or more drives on the DRM- 7000).
¶The positions where connector panels are to be attached. (Note that the
¶The SCSI IDs to be assigned to each of the drives to be installed. (Note that it is impossible to assign the same SCSI ID to two or more drives on the same SCSI bus.)
¶The connecting plan of the cables running between individual drives and connector panels.
¶Which drives are to be terminated (i.e., the drive’s termination switch of the terminal drive in each SCSI chain is to be turned on).
An example of how SCSI cables should be connected is shown on p. 19.
The power unit provided as standard equipment is capable of supplying power to rear bays #1 – 8. The total power consumed by these eight drives should not exceed the following:
DC +5 V 12 A or less DC +12 V 8 A or less
The maximum current capacity of a single connector is as follows:
DC +5 V Max 4 A
DC +12 V Max 4 A
8
<DRC1184> En
By adding an optional expansion power unit to the DRM- 7000, power can be supplied to rear bays #9 – 16.
The maximum power consumption of these upper bays and the maximum amount of power which may be supplied over a single connector is the same as that of the lower bays (i.e., Bay #1 – Bay #8).
NOTE:
¶Be sure never to use any
¶When turning off the power and turning it back on, always be sure to allow an interval of 10 seconds or more to elapse after turning off the power before turning it back on. Note that this must be done because there are times when the power is not switched off immediately even after the power switched has been flipped off when few drives have been installed in the changer.
ADD-ON PRODUCTS
The following components may be purchased separately for use with the Pioneer
50-disc magazine
Used to store discs within the changer, these magazines come in both normal and locked types which can be installed in whatever combination best fits your needs.
¶50-disc magazine (locked-type)
[DRM-AL751]
These disc magazines are designed so that the lock is not released even when a magazine is removed from a changer. Therefore the mailslot is necessary to insert discs into these magazines or remove discs from them. These magazines are extremely effective for use in situations where they are used in combination with a host computer which supports offline media management. (See p. 7 for further details.)
