If a phone modem needs to be replaced, what type is recommended?

Whether a laptop’s modem can make a good connection depends on the type of modem being called at the weather station:

• If the call is being made to a COM220, a software modem (sometimes called a Winmodem) should work.
• If a COM200, COM210, or DC112 is used at the station, select an external modem that isn’t a software modem. Customers have reported success using the U.S. Robotics USR5686G and the USR 5637 series of USB dongle modem. Because the USR5686G requires a serial port, a USB-to-serial adapter may be necessary. Campbell Scientific offers the 17394 USB-to-9-Pin Male RS-232 Cable.
