Memory installed varies from system to system depending on the requirements. Larger amounts

of memory provide more cache area for sound recording and playback as well as additional sound

model memory.

Each system has a CPU reset button for hard reboot of the model processor. The reset button is

located on the front of the chassis.

** WARNING **

The reset button should only be used to reboot the Model Processor if there is a complete CPU or

operating system failure and the keyboard is inoperative. At all other times, simultaneously press

[ctrl][alt][del]

to reboot. Using the reset button during DACS operation can prevent recorded audio

data buffered in cache memory from being written to disk before system reset, resulting in loss of

data.

CPU

The CPU type used in the system depends on the time of purchase and whether any CPU upgrades

have been incorporated. The typical CPU is an Intel- or AMD-based Pentium processor.

Hard Drive

On most DACS, the hard drive is a ﬁxed drive of at least 7GByte in size. Larger drive options are

available at time of purchase or as upgrades. Applications with a large number of recorded

sounds, or applications that record voice communications to the hard disk, will require more hard

drive space.

Removable drive options are also available. Platforms with removable drives will include a

removable drive docking bay as part of the chassis. The bay will accommodate a 3.5” removable

drive cartridge which must be purchased through ASTi to ensure proper operation

Fixed drives are standard on all platforms, with removable drives available as options.

For systems with a removable drive, the removable cartridge containing the drive must be ordered

separately. Size is generally 7GByte or larger. Size options and upgrades are also available.

Specially conﬁgured record platforms may have a high-performance SCSI drive with a caching

controller.

Floppy Drive

Floppy drives are standard on 2U and 4U systems. The drive is a standard 1.44MB, 3.5” ﬂoppy

disk drive.

Monitor and Keyboard

A 101-key keyboard are supported by the 2U and 4U platforms via PS/2 connector on the rear of

the chassis on the CPU card; the MicroDACS requires a USB keyboard. Keyboards must be pur-

chased separately. Legacy DACS may have the older, AT-style keyboard connections on the front

or rear of the chassis.

The video connection is via a 15-pin, female, high-density, sub-miniature, “D” style connector

located on the back of the chassis. It supports a standard SVGA or multisync monitor, also pur-

chased separately.
