Leave the field blank if the DIRECTOR EC is not attached to a network

or if you do not want to receive unit attention messages.

Recording Speed (Required)

The Recording Speed pull-down allows you to set the recording speed as

determined by the capabilities of the recorders installed in the DIRECTOR

EC.

• Click the Recording Speed pull down and select the desired recording

speed “maximum speed”, or “4x, 8x, 12x, 16x, 20x, 24x, 32x, or 48x

speed”.

• Click on “Apply” to activate the changes.

Asynchronous Mode (Required)

The Asynchronous Mode pull-down is used to instruct the DIRECTOR EC

how to process jobs. This affects both how jobs are handled and how the

drives operate. Jobs and drives can run either synchronously or

asynchronously. In the table below you will find each mode detailed. Let’s

define the basic modes first:

Jobs=Synchronous / Asynchronous

When jobs are Synchronous, they are completed in the order in which

they were submitted. Take for example two jobs submitted for one copy

each. The first job is of a 650MB master while the second job is only

10MB. While the second job submitted will be completed prior to the

first job, it will not be outputted to the accept spindle until the second

job has been completed. When jobs are Asynchronous they will be

outputted to the accept spindle as they are completed.

Drives=Synchronous /Asynchronous

Drives can also run either synchronously or asynchronously. In

synchronous mode, all the drives in use for a given job, run in tandem

or parallel to one another. In asynchronous mode, all the drives in use

for a given job, operate independently of each other. For example if you

submit a job for three copies and the drives are operating

synchronously, the copying process will not begin until all drives

become ready. On the other hand, if the same job were submitted with

the drives operating asynchronously, each drive would begin to write as

soon as it becomes ready, independently of any other drives which may
