This simple model shows how a single floating point number can be converted to ASCII and transmitted over a serial link. The sending serial port and receiving serial port can be in the same system or in different systems.
To test this model:
The target computer must have two COM ports.
Connect COM1 to COM2 with a null modem cable.
This example is configured to use baseboard serial ports (COM1 and COM2). You can also use COM3 and COM4 by changing the board setup in the Baseboard blocks. Other serial blocks could be used in place of the Baseboard blocks. For instance, a single Quatech® 4-port block could be used whereby you send on port 1 and receive on port 2.
