Chapter 1: INTRODUCTION

The RS-232Four Port Smart Switch/Port Combiner, Model 232SS2, allows oneRS-232host device to connect to as many as fourRS-232devices. The switch can be controlled in two different ways. The first way is referred to as smart switch mode. In this mode, the switch is controlled by sending a programmable preamble code to the "Master" port of the 232SS2. The other 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 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 four slave ports will become DCE ports. The 232SS2 supports the following signals: TD, RD, RTS, CTS, DSR, DCD, and DTR.

The 232SS2 has an enhanced 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 232SS2 will work with baud rates from 1200 to 115,200 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 232SS2. The communication between the devices can use any format or data rate.

There are four LED's on the 232SS2 to indicate which port is connected to the master port. The master port has a DB-25Sfemale connector and the slave ports haveDB-25Sfemale connectors. The 232SS2 requires 12Vdc at 100ma. which is provided through a 2.5mm power jack.
