serial port. Each port uses a dedicated UART and includes an 8K
byte transmit buffer and an 8K byte receive buffer (16K bytes total).
Each port can be independently configured for data rate, data
format, and protocol. The Master port can send and receive data
from one of the Slave ports while the other Slave ports continue to
buffer data. The Master device can also broadcast the same
message to two or more Slave ports at once.
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 done through user-defined
three or four character command strings. All control sequences are
removed from the data stream, making the switch transparent to the
Slave devices. The PC setup software provided walks the user
through all possible parameters.
four ports. Two units can also be used back-to-back to provide
automatic connection between devices over a single data channel.
LEDs on the 232BSS4 indicate when the unit is powered up and
which port is selected to send data to the Master port.
