Telephone Modem - Campbell Scientific

Telephone Modem
Model COM200
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.
PC208(W) Software for the IBM® PC computer supports error-checking, manual or automated dialing, and can
run unattended to take advantage of lower off-hour telephone rates.
We also offer cellular transceivers and voice-synthesized modems; contact Campbell Scientific for additional
information.
