Chapter 1: INTRODUCTION
The RS-232 Five Port Expandable Smart Switch, Model
232XS5, allows one RS-232 host device to connect to as many as
five RS-232 devices. The switch can be controlled in three different
ways. The first way is referred to as smart switch mode or code
activated switch mode. In this mode, the switch is controlled by
sending a programmable preamble code to the "Master" port of the
232XS5. The second way the switch can be controlled is referred to
as port combiner mode. In port combiner mode, a slave port can
gain access to the master port by asserting a handshake line. If
none of the slave ports have their handshake line asserted, the
switch can be controlled using the preamble code. The third way the
switch can be controlled is the expander mode in which up to four
switches can be cascaded together to form up to 17 slave ports.
The master port can be configured as a DTE or DCE port by an
internal switch setting. If the master port is configured as a DTE
port, the five slave ports will become DCE ports. The 232XS5
supports the following signals: TD, RD, RTS, CTS, DSR, DTR and
DCD.
The 232XS5 has an enhanced timer mode which offers special
timer features. The timer features can be used to prevent slave
devices from receiving preamble commands, inadvertently switching
from binary/graphic file transfers, and inactive slave devices from
holding control of the master port.
The 232XS5 will work with baud rates from 1200 to 115.2K bps;
7 or 8 data bits; even, odd or no parity; and 1 or 2 stop bits (7,N,1 is
not allowed).
NOTE: The data format and rates mentioned are used to switch
the 232XS5. The communication between the devices can use
any format or data rate.

There are five LED's on the 232XS5 to indicate which port is
connected to the master port. The master port has a DB-9S female
connector and the slave ports have DB-9P male connectors. The
232XS5 requires 12Vdc at 100ma. which is provided through a
2.5mm power jack.
