c. Recommended Modem
Selection of a telephone modem for use with the OCS is highly dependent on environment. For a
relatively benign, low-noise environment, an off-the-shelf external modem like a U.S. Robotics Sportster
Modem can work well. For a more industrial environment, however, it is appropriate to use a telephone
modem designed for that environment. Manufacturers such as Datalinc and Sixnet have models, which
have been known to work in more harsh environments, at a higher cost. If a modem is used, which is not
appropriate for the environment, there may be little that can be done to correct the situation other than
change to a more appropriate model.
For detailed information regarding the use of modems with Control Station Products, contact Technical
Support. (See page 18.) You can also find specific application information (cabling, modem commands,
etc.) in the Cscape Help file as well.
