Introducing the EN/SC Adapters

Thank you for purchasing an Asanté EN/SC™ SCSI-to-Ethernet
Adapter.

An Asanté EN/SC adapter enables you to connect your desktop Mac-
intosh or PowerBook to a 10BaseT or Thin Ethernet.

The Asanté EN/SC Adapter Family includes the Mini EN/SC Adapter
group and the Micro EN/SC Adapter group:

Mini EN/SC Adapter group

Mini EN/SC Adapter

Mini EN/SC 10T Adapter

Micro EN/SC Adapter group for PowerBook

Micro EN/SC Adapter

Micro EN/SC 10T Adapter

An Asanté EN/SC Adapter passes Ethernet packets between the Mac-
intosh and the Ethernet network using the Macintosh standard SCSI
interface. The Mini EN/SC Adapter also enables you to attach addi-
tional SCSI devices to your Macintosh in a SCSI daisy chain (such as
a hard drive, scanner, or CD-ROM). The Micro EN/SC Adapter
attaches directly to the PowerBook’s HDI-30 port and does not offer
SCSI daisy-chaining.

Asanté EN/SC Adapters are compatible with Apple System Software
6.0.7 and higher. Asanté recommends you use them with slotless
Macintosh computers and PowerBooks. Refer to Appendix B for
compatibility information.

This chapter describes the features of the EN/SC Adapters.
