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.
