CHAPTER 2 Introducing the Vanguard
Multiport 4530CP
Controller
Congratulations on purchasing your Aurora Technologies Vanguard Multiport™
controller. Combining on-board RISC processing, dedicated data buffers, and flow
control processing, Vanguard Multiport controllers off-load communications over-
head from your host CPU and your network for optimum system performance.
Introducing the Vanguard Multiport Controllers
The Vanguard Multiport series of SBus-bus, sync/async controllers provides the
performance and reliability needed for high-speed serial communications. Data
transfer rates up to 115.2 kbps asynchronous and 256 kbps synchronous (depending
on processor speed), full duplex, are supported. Vanguard Multiport controllers are
available for any SPARC-compatible system or personal computer with a SBus
(cPCI) expansion bus, running Solaris SPARC or Solaris x86. (See the Driver
Release Note for supported Solaris releases.)
