Hardware Installation Card

Introduction
This Hardware Installation Card discusses the Hostess i
line of 8- and 16-port serial controllers.
The Hostess i serial card fits into the ISA or EISA slot of a
personal computer, and supports either asynchronous or
synchronous serial communications in both RS-232 and
RS-422 modes. You can install up to four Hostess i cards
in a single computer, for a maximum of 64 serial ports per
system (depending on card configuration).
Hostess i 8-port cards can be upgraded to 16-ports with a
simple plug-in module. You can also add up to 8 MB of
memory to each card using standard 30-pin SIMMs.

Before Installing the Hardware
Before you install the Hostess i card, you must do the
following:
1. Set the hardware I/O address.
2. Configure ports for RS-232 or RS-422 operation.
3. Install and configure the 16-port upgrade, if required.
4. Install memory upgrades, if required.
The following sections discuss these procedures.

Installing Memory Upgrades
The Hostess i card features 128KB of DRAM memory.
This can be expanded up to 8 MB using standard 30-pin
SIMMs (80 ns or faster, parity or non-parity).
The SIMM sockets are located at the left end of the card.
SIMMs must be installed in matched pairs. (For example,
install two 4MB SIMM modules. See the Specifications
table for a list of valid SIMM types.)
SIMMs have alignment notches and pegs, and cannot be
reversed. To install a SIMM, lay the connector edge in
first, then gently press the SIMM down until the spring
latches snap into place. DO NOT FORCE THE SIMM
INTO THE SOCKET.
To remove an installed SIMM, gently spread the spring
latches on the sides, then pop the SIMM up. Again, do not
force or pry a SIMM out of its socket. Doing so may
damage the SIMM, the socket, the Hostess i card, or all
three.
