Functional Description
Our most intelligent and versatile switch, the 232BSS4 provides communication to four devices from one
serial port. Each port contains a dedicated UART and an 8K byte transmit and receive buffer, allowing each
ports data rate, data format, and protocol to be configured independently. The Master port can send and
receive data from one Slave port while the other Slave ports continue to buffer data. The Master can also
broadcast the same message to two or more Slave ports at once. The switch can also be configured to
send data automatically to the Master port from each of the Slave ports when data is present with an
optional preamble identifying the port. It can also provide two-way communications between the Master port
and one Slave port at a time. Switching and control is accomplished through user defined three or four
character command strings. These control sequences are stripped from the data stream, making the switch
transparent to the Slave devices. Switches can be cascaded to expand the 232BSS4 to more than four
ports. Two units can also be used back-to-back to provide automatic connection between devices over a
single data channel. LEDs indicate when the unit is powered up and which port is selected to send data to
the Master port. Setup software is provided on CD and is compatible with Windows 98, ME, 2000, XP, and
Vista. A 12VDC power supply with a 2.5mm (positive tip) phone jack is required (sold separately).
