Port Configurations

The 232BSS4 provides a dedicated UART to all five ports. This allows any port to be individually configured for baud rate, number of data bits, parity, and hardware (RTS/CTS) handshaking. Configuration of all the ports is done through the setup software.

Baud Rate:

Each port is configurable for the following baud rates: 1200 2400 4800 9600

19.2K

38.4K

57.6K

or 115.2 kbps

Data Bits:

Each port can be configured for Seven or Eight data bits. Note: If the Master and Slaves are set up differently, the port set for Seven data bits cannot transmit the eighth bit.

Parity:

Each port can be configured for Even, Odd, or No parity. Because the Master port uses a slightly different UART, it is not capable of receiving only seven bits, thus seven data bits with no parity is not allowed on the Master port. All other configurations are possible.

Stop bits:

Each port uses 1 stop bit. This value is currently fixed and can not be changed in the setup software.

Hardware(RTS/CTS) Handshaking:

Each port can be configured to hold data until its input handshake line goes high. On the Master port, pin four (RTS) would have to be held high by the host device in order for the 232BSS4 to send data. On the Slaves, pin eight (CTS) needs to be held high by the Slave device for the 232BSS4 to send data. The connected devices can prevent data from being sent from the 232BSS4 by holding their corresponding handshake lines low.
