Overview

This user’s guide provides information on how to install and configure the Adaptec AMM-1570 and AMM-1572 SCSI Audio Host Adapters. The AMM-1572 is identical to the AMM-1570 except that it has an onboard floppy disk cont roller that suppo rts up to two floppy disk drives. In this user’s guide, the AMM-1570 and AMM-1572 are referred to jointly as the AMM-1570/1572.

What is the AMM-1570/1572?

The AMM-1570/1572 provides full SCSI host adapter functionality and superior audio perform ance for your SCSI and multim edia devices. This is accomplished through the integration of two discrete functional modules onto a single board: A SCSI module and an audio module.

The AMM-1570/1572 SCSI module provides a powerful multitasking interface between the ISA bus and the SCSI bus featuring 16-bit transfer capability. Up to seven individually configured SCSI devices can be connected to and supported simultaneously by the AMM-1570/1572.

The AMM-1570/1572 audio module is based on a Digital Signal Processor (DSP) that can off load many com puter intens ive audio and video processing tasks from the host adapter. Through the input and output jacks, a variety of audio equipment can be connected to the AMM-1570/1572. The audio mod u le provides

Types of Cables Required

Before you actually install the host adapter, be sure you have the correct cables for your particular instal latio n. The type of cables required depends on the type of devices you plan to connect to the SCSI bus: either external or internal. The type of connectors attached to the cables also depends on the configuratio n of your ins tallat io n.

Type of Connector on Host Adapter Type of SCSI Cable Type of Connector on SCSI Cable

Internal 50-pin SCSI ribbon cable Uns hrouded 50-pin header, com-

patible with unshielded Alternative 2 connector.

External 50-pin shielded cable Shielded 50-pin Alternative 2

connector.

Maximum Cable Lengths

When the SCSI bus contains a Fast SCSI host adapter, such as the AMM-1570/1572, and one or more Fast SCSI devices, the total length of all cables (internal and exter nal) con nect ed to the bus should not exceed 3 meters to ensure reliable operation. If no Fast SCSI devices are connected, the total length of all cables should not exceed 6 meters.

External SCSI Connector Mounting Bracket

If you are connecting external SCSI devices to the A MM-1570/1572, the external SCSI connector mounting bracket must be installed. This bracket allows you to connec t external SC SI devic es to the AMM-1570/1572. The moun ting bracket is available from Adaptec and is normally included with all AMM-1570/1572 kits. Refer to Installing the External SCSI Connector Mounti ng Brack et on page 3-8 for detailed instructions on installing the bracket.

Before physically installing the AMM-1570/1572 in your system, the AMM-1570/1572 must first be confi gured for oper atio n. Once it is installed in your system , it is difficult to change its configu rati on.

This chapter provides instruct io ns on how to configure the AMM-1570/1572. It discusses th e concepts of termin atio n an d SCSI IDs and explains the importance of properly terminating and assigning SCSI IDs to each SCSI device (including the host adapter) connected to the SCSI bus. In addition, this chapter describes in detail how to configure each of the jumper blocks on the AMM-1 570/1572.

Termination on the SCSI Bus

To prevent line noise from bouncing back through the SCSI bus, the first and last physical SCSI devic es on the SCSI bus must have a set of resistors calledterminators either installed or enabled. If the termi- nators on the first and last SCSI device are not installed or enabled, the signal may echo when it reaches the end of the cable; that echo often seems like a real signal to the SCSI device.

Identify which two SCSI devices will form the physical endpoints of your SCSI bus. These devices at the ends of the SCSI bus must be terminated. All other SCSI devices installed betw een the ends of the SCSI bus must have their terminators eith er removed or disabl ed.

Note:External SCSI devices are connected to an external

SCSI connector mounting bracket that is attached to the AMM-1570/1572. When attach ed, th e mou nti ng bracket becomes a com po nent of the board; it is not a device on the SCSI bus. See Install ing the External SCSI Connector Mounting Bra cket on page 3-8.

Internal and External Devices

When both internal and external SCSI devices are connected to the host adapter, the last external device and the last internal device cabled to the host adapter is terminated. Since the host adapter is situated in the middle of the SCSI bus, and does not form a physical endpoint, host adapter termination is disabled.

Terminating SCSI Devices

Most SCSI devices use a jumper or a switch locat ed close to their SCSI connector(s) to control termination. On some SCSI devices, you must physically remove or install terminator resistor module(s). Refer to the manufacturer’s documentation to determine how to enable or disable termination on your particul ar SCSI device(s ).

Note: Since the AMM-1570/1572 always supplies termi-

nation power on the SCSI bus, terminat io n power sup plied by other SCSI devices should be disabled.

Terminating the AMM-1570/1572

Host adapter termination is determ ined by the types (inter nal and/or external) of SCSI devices connected to the AMM-1570/1572. The table below describes the possibl e configurati on s for host adapter termination.

The factory installed bus terminators on the AMM-1570/1572 are located below the SCSI internal connector and are enabled (Installed) by default. To disable term inati on on the host adapter, remove all three terminators.
