General Description

The COM200 Modem enables communication between a computer and a Campbell Scientific datalogger (CR510, CR500, CR10(X), 21X, CR23X, CR5000, or CR7) over a public switched telephone network. A Hayes-compatible modem is required at the computer; the COM200 is connected to the datalogger. The COM200's wide operating temperature range and low power requirements optimize it for use in remote applications.
