El modem telefónico COM220 permite comunicar el datalogger con un ordenador por medio de telefonía analógica convencional terrestre. En la parte del PC hay que disponer de un modem Hayes-compatible. El modem COM220 se conecta al datalogger. La mayoría de dataloggers Campbell Scientific son compatibles con el COM220.
Leer másEl modem COM220 dispone de puerto CS I/O, terminales para alimentación eléctrica, terminales roscados, y jack RJ-11C. El puerto CS I/O del datalogger se conecta al puerto CS I/O del COM220 mediante el cable SC12. En el jack RJ-11C se conecta la linea telefónica, que hay que proteger de sobretensiones (a cargo del usuario). Los terminales roscados GND, RING, TIP, se pueden usar también para conectar el COM220 a una linea telefónica con protector de sobretensiones.

Not directly. A datalogger needs to be used with it, and the remote caller needs to be running LoggerNet or PC400.
All dataloggers will work with the COM220 except the CR200X-series dataloggers.
Cable runs of that length usually will require a booster of some sort. Contact the local phone company for recommendations.
There are several possibilities as to the cause. Contact Campbell Scientific for assistance in determining the specific cause.
Refer to the “Installation” section of the COM220 Telephone Modem Instruction Manual.
Campbell Scientific does not recommend VoIP, as it does not work well with data transfers.
No. The COM220 is designed to pick up a call and cannot be overridden. A better approach would be to use a phone line sharing device. Note that the phone line sharing device must simulate a normal phone line accurately or it won’t work correctly with the COM220.
One phone line sharing device that has been used successfully by our customers is “The Stick” by Multi-Link. This device takes one incoming phone line and breaks it out to four separate lines. It does require ac power to run. For more information, refer to the Multi-Link website.
Typically, software such as LoggerNet or PC400 is needed to connect to a datalogger and download the data.

Habitualmente se pasa un cable de linea telefónica desde la toma telefónica hasta el protector de sobretensiones en el lado del COM220, y del protector a los terminales Ground, Tip, y Ring del COM220. De forma alternativa, si la linea ya viene protegida contra sobretensiones, se puede pasar el cable telefónico directo al jack RJ11C del modem COM220.
Los ajustes que vienen por defecto no son compatibles con dataloggers que no sean PakBus (por ej. dataloggers CR5000, CR7). Para esos dataloggers el DIP switch hay que cambiarlo; ver manual del COM220 para más detalles.
Se suministra un cable SC12 para conectar el COM220 al datalogger.
Tanto nuestro software LoggerNet como PC400 son compatibles con el COM220. Ambos soportan corrección de errores automática y llamar al datalogger. LoggerNet permite además la programación de llamadas para descarga de datos, y funcionar de forma totalmente desatendida.
El COM220 requiere condiciones de trabajo sin condensación; recomendamos utilizar nuestros armarios, y se suministran los accesorios para fijar el COM220 directamente en la placa de montaje.
