Chapter INTRODUCTION
RS-232 Five Port Expandable Smart Switch, Model 232XS5, allows RS-232 host device connect many five RS-232 devices. switch controlled three different ways. first referred smart switch mode code activated switch mode. this mode, switch controlled sending programmable preamble code "Master" port 232XS5. second switch controlled referred port combiner mode. port combiner mode, slave port gain access master port asserting handshake line. none slave ports have their handshake line asserted, switch controlled using preamble code. third switch controlled expander mode which four switches cascaded together form slave ports. master port configured port internal switch setting. master port configured port, five slave ports will become ports. 232XS5 supports following signals: RTS, CTS, DSR, DCD. 232XS5 enhanced timer mode which offers special timer features. timer features used prevent slave devices from receiving preamble commands, inadvertently switching from binary/graphic file transfers, inactive slave devices from holding control master port. 232XS5 will work with baud rates from 1200 115.2K bps; data bits; even, parity; stop bits (7,N,1 allowed). NOTE: data format rates mentioned used switch 232XS5. communication between devices format data rate.

Each device will have inputs pins that correspond outputs same pins other device. example, device will transmit data DB-25) device will receive data DB-25). serial printers devices, modems devices. Originally RS-232 standard specified only D-sub connector. Since then, D-Sub supporting only portion original RS-232 signals been used extensively, starting with migrating into other peripherals. pinouts this connector have since become EIA/TIA standard. This standard specifies device that transmits receives with having opposite configuration. compatible (DTE device) going connected 232XS5 master port, master port should configured port. modem (DCE device) going connected master port, should configured port. master port configured port (data received port (data received setting dipswitch "SW1", position configure master port port, move dipswitch "SW1", position "OFF" position.

Port Combiner Mode
With 232XS5 with master port, this mode allows Slave Ports select master port using input line. also still allows selection from master port preamble code described Smart Switch Only Mode section. Jumper "JP6-C" must (removed) port combiner mode. Port combiner mode accessible when unit port expander, JP6-B must (installed). When goes high five slave ports, will establish connection from that port master port. This works first-come-firstserved basis. multiple ports have their lines high, port that been waiting longest will next connected master port. example (initial conditions slave ports with lines asserted.), chronological order, Port asserts line, Port asserts line, Port asserts line then Port disasserts line. When Port asserts line, connection will made between master port Port When Port disasserts line, Port will disconnected Port will connected master port. When Port disasserts RTS, Port will disconnected Port will connected master port. example, port configured port. order establish connection master port, port must high (assert). 232XS5 would recognize this prompt connection master port. connection would dropped soon port brought low. Ports raise time request connection. However, port connected master port, data sent from devices ports 232XS5 will lost. 232XS5 does have buffering.

NOTE: When port selected Master Port, lines will ignored until Master Port sends turn code. When Master Port selected RTS, preamble codes will ignored. port combiner function available with Master Port configured expansion mode. typical application would have tied together master port. When port asserted, port will asserted when connection established. port connected master port, then that port will remain low. Therefore, port monitor handshake line determine connection been established.
Enhanced Timer Mode Timer Features
232XS5 enhanced mode, which offers special timer features. timer features used prevent slave devices from receiving preamble commands, inadvertent switching from binary/graphic file transfers, inactive slave devices from holding control master port. timer different modes: inactivity mode inadvertent switch mode. When inactivity mode, 232XS5 will monitor data lines. there activity specified time, selected slave port will disconnected from master port. When inadvertent switch mode, 232XS5 will ignore switching commands specified period time. After this time expired, selected slave port will disconnected from master port. timer functions enabled jumper setting through software commands. Jumper JP6-A must (removed) 232XS5 enhanced mode. software commands follow same format preamble codes used switching. There commands that must sent 232XS5 timer functions: Timer Value Timer Mode. These commands require additional byte data. Timer Value command requires third byte ASCII character. data byte (fourth byte) must value between ASCII ASCII "9". value used disable timer. time Timer Value command determines length time 232XS5 wait before disconnecting inactive port, length time will ignore switching commands from master.
