Multiport Serial I/O Adapter Hardware Reference Guide 3
Overview
Equinox SuperSerial Technology (SST) Adapters are intelligent, high-
speed (up to 920k bps on each port) Multiport Adapters providing high
performance serial I/O solutions for PCI, ISA and EISA bus systems. All
port interfaces are standard RS-232 with full modem control and voltage
surge protection on every pin.
SST Adapters appear to the system host processor as memory. That is,
they are memory mapped devices. Each adapter is automatically mapped
into system memory at the time of device driver installation. The device
driver soft-configures all adapters each time the system is initialized
(booted). See the appropriate software documentation located on your
SuperSerial CDROM for detailed device driver information.
The SST Adapter (see Figure 1 below) occupies a slot in the host computer
and provides the intelligent functions to "off-load" the CPU serial
communications processing tasks. Adapters are available for PCI, ISA and
EISA bus systems.
Installation
Use the following procedure to install your SST Adapter. Alternatively,
you may follow the installation instructions presented in your host system
documentation.
1. Set the host computer system power switch to OFF and disconnect the
power cord.
2. Locate a free expansion slot.
3. Insert and secure the adapter firmly into the expansion slot.
4. Replace the power cord and turn the host computer system ON.
5. Install the device driver software (see CDROM for details).
