Legacy Serial Setup

Set up baseboard serial communications

• Library:

• Simulink Real-Time / RS232 / Mainboard

• 

Description

The Legacy Serial Setup block sets up baseboard serial communications.

Parameters

Serial port — Select serial port

Legacy Serial Port 1 (default) | .. | Legacy Serial Port 8 | USB Serial Port 1 | .. | USB Serial Port 8

Select the RS232 serial port for communications. If using USB-to-serial adapters, the target computer detects these adapters as serusb1, serusb2, and so on in the order that the adapters are connected to the serial devices. The order of port assignment is retained through the power cycle of the target computer or serial device if there is no change in the connections to the ports.

Programmatic Use

port

Baud rate — Select serial port baud rate

115200 (default) | 57600 | 38400 | 19200 | 9600 | 4800 | 2400 | 1200 | 600 | 300 | 110

Use this value to select the serial port baud rate.

Programmatic Use

baud

Number of data bits — Select serial port data bits

8 (default) | 7 | 6 | 5

Use this value to select the number of serial port data bits.

Programmatic Use

width

Number of stop bits — Select serial port stop bits

1 (default) | 2

Use this value to select the number of serial port stop bits.

Programmatic Use

nstop

Parity — Select serial port parity

None (default) | Even | Odd | Mark | Space

Use this value to select serial port parity.

Programmatic Use

parity

Enable auto RTX/CTS — Select serial port RTX/CTS mode

off (default) | on

Use this value to select the serial port RTX/CTS mode.

Programmatic Use

ctsmode
