Overview
IBM Serial I/O Adapters are intelligent, high-speed (up to 230.4
kbps on each port) Multiport Boards providing high performance
serial I/O solutions for PCI bus systems. All port interfaces are
standard RS-232 with full modem control and voltage surge
protection on every pin.
IBM Serial I/O 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 Software
Reference Manuals located on the CD ROM for detailed Device Driver
information.`
The IBM Serial I/O Adapter (see Figure 1 below) occupies a single
PCI slot in the host computer and provides the intelligent functions
to "off-load" the CPU serial communications processing tasks.

Installation
Note: Please refer to the user manual that came with your
personal computer for detailed installation instructions.
Use the following procedure to install your Serial I/O Adapter Card:
1. Set the host computer system power switch to OFF and
disconnect the power cord.
2. Locate a free PCI expansion slot.
3. Insert and secure the board firmly into the expansion slot.
4. Connect the Host SSP-16 (37L1476) cable between the SST16P board and the Connector Panel (see Figure 1).
5. Replace the power cord and turn the host computer system ON.
Software Installation
Refer to the Quick Start Card that came with the CD ROM for
detailed instructions on loading the Software Driver
Plug and Play
Peripheral Component Interconnect (PCI) system architecture has a
design feature termed Plug and Play. This feature automatically
detects, identifies and configures the currently installed devices
each time the system is booted. Therefore, whenever an adapter
card is installed (or removed) in a PCI system, the card is recognized and configured immediately upon restart.
Connector Panels
IBM Serial I/O Connector Panels (CP) provide sixteen RS-232
interfaces. There are two types of CPs available from IBM as shown in
Figure 2. The CP-16 DB has sixteen male DTE connectors (Figure 3).
The CP-16 RJ has sixteen 10-wire female RJ-45 connectors (Figure 4).
