3. Deploy the project, and then specify settings on the Serial PASHA tab to match your

Testing and debugging
Using MediaMatrix hardware
You can use a terminal emulator program to manually send ASCII PASHA commands to a
MediaMatrix node via one of the available serial ports.
Note: If you are using a NION RS-232 port, console mode must be disabled. See the section
Specifying the function of the RS-232 serial port in the NION Hardware Manual.
 To use MediaMatrix hardware
1. Connect a serial cable between the PC serial port and the serial port on the MediaMatrix
node.
2. Start a terminal emulator program, then specify connection settings to match those already
specified on the MediaMatrix node. For example (to match the settings in the earlier
example):
 baud rate 57600
 8 bit data
 no parity
 1 stop bit
 no flow control.
3. Enable the echo feature in the terminal emulator program if it is switched off.
In Hyper Terminal, you can do this by clicking ASCII Setup, and then selecting the Echo
typed characters locally check box.
