Introduction RS-232 Eight Port Expandable Smart Switch (232XSSD4) allows RS-232 host device connect eight asynchronous serial devices. Refer Figure Four RS-232 ports four RS232 RS-485 (two four wire, send data contol) standard 232XSSD4, depending pins use. Other options additional RS-422/485 ports available contacting technical support. 232XSSD4 easily expanded sixty additional ports total sixty-eight ports using Model 232PE Port Expander. Ports configured RS-232 support signals RTS, CTS, DTR, Refer Figure Ports configured RS-422/485 support signals only. Refer Figure Master port configurable. RS-232 ports through configured ports. 232XSSD4 will switch with baud rates from 38,400 bps, data bits, even, parity, stop bits. After switch made 232XSSD4 transparent data flow. There nine indicator LED's front 232XSSD4. Eight LED's represent ports through indicate selected port. ninth power indicator. connectors located back 232XSSD4, twenty expansion connector, DB-25S female Master port connector, eight DB-25P male connectors ports through "H". Refer "Front View" diagram. Port selection accomplished sending programmable control string "Master" port Expandable Smart Switch. This control string consists user-defined character, address character, port character. When 232XSSD4 receive control string "Master" port will connected designated port. There delay through 232XSSD4 data buffered. When 232XSSD4 Smart Switch Mode Port will selected power eight ports 232XSSD4 also used smart switch/port combiner. addition using Master Port port selection, eight ports select Master Port asserting their line. This function enabled setting switch inside 232XSSD4. 232XSSD43800 Manual

Default Values type XSSTSR command line with parameters, omit parameters, default value missing parameter will used. default values are: Description Port Address Baud Rate Parity Data Bits User Defined Char. Command String Sequence Help Screen installing XSSTSR using XSSTSR.COM method, type XSSTSR? press ENTER obtain list commands their options. Selecting Ports There different ways which Smart Switch port selected: either through command line pressing predefined sequence after XSSTSR installed. When request change ports made, using either method, first current port turned off, then port selected turned methods described follows: 232XSSD43800 Manual

Default Value 02F8h (COM 9600 Parity Data Bits (CTRL Character <Left Shift><ALT><A|B|C|D|E|F|G|H|N>
Method This method enables user select Smart Switch port pressing pre-defined sequence keys same time after XSSTSR installed (refer Program Installation section). Example: sequence <Lft Shift><Alt><A|B|C|D|E|F|G|H|N> selected, change ports would press same time:
Left Shift select port Left Shift select port Left Shift select port Left Shift select port Left Shift select port Left Shift select port Left Shift select port Left Shift select port Left Shift turn ports
Then press address character indicate location desired port. This character required when turning ports off. Command Line Method This method enables user select Smart Switch port through command line. specify Smart Switch port through command line, would type XSSTSR followed command symbol letter port.

Example turn port 232XSSD4 would type XSSTSR command line press ENTER key. Example turn port 232PE address would type XSSTSR command line press ENTER key. Before smart switch port selected, check made determine communication port computer busy transmitting. communication port busy tone will generated notify that port busy that port selection cannot made. CAUTION: software package using transmission running fast baud rate (115200), XSSTSR detect Smart Switch port busy transmission could interrupted. XSSTSR does detect when 232XSSD4 port receiving data. Therefore, data being received, Smart Switch port still changed. Uninstalling XSSTSR un-installed easily typing XSSTSR pressing ENTER key. some cases XSSTSR will un-install. This caused another terminate stay resident (TSR) being installed after un-install XSSTSR when this occurs, other must first un-installed, then XSSTSR un-installed normally.
