This application note explains the process for changing the MM200 analog output settings from a Windows PC. The serial communications program Tera Term must be installed prior to following these instructions, and a serial to USB converter must be purchased. If you don’t have Tera Term installed, click here to install the latest version from GitHub.
Instrucciones
1. Conecte el conversor serie a USB a su PC.
2. Abra el menú Inicio.
3. Abra el Panel de control.
4. Open Hardware and Sound.
5. Abra el Administrador de dispositivos.
6. Despliegue el menú desplegable Puertos (COM y LPT).
7. Determine la asignación de puerto COM para su conversor USB a serie, en este ejemplo el conversor está asignado a COM3.
8. Abra TeraTerm.
9. Abra el menú Configuración y seleccione la opción Puerto serie....
10. Change the Port setting to the COM port for your USB to serial converter, in this example it is COM3.
11. Ensure that the remainder of the settings are the following, then select OK:
- Tasa de baudios: 9600
- Data: 8 bits
- Paridad: ninguna
- Parada: 1 bit
- Control de flujo: ninguno
- Retraso de transmisión: 0 mseg/car, 0 mseg/línea
12. Open the Setup menu and select the Terminal setup… option
13. Asegúrese de que los ajustes son los siguientes y seleccione OK:
- Recibir: CR+LF
- Transmite: CR+LF
- Comprobado el eco local
14. Send the following commands to change the analog output setting, this example changes the 7B output to Linear (<CR> is equivalent to pressing the Enter key). A full list of commands and analog output options can be found in the table below.
