SECTION 9 Modems

9.1 Introduction to Modems

Modems allow you to communicate, over telephone lines, with loggers at remote sites. A

remote logger behaves the same as if it were connected directly to your computer. Modems

can relieve you of the need to physically go to the remote location to communicate with a

logger.

Equipment Needed

To communicate with a remote logger you will need:

A telephone line to the remote logger site.

Two modems: one at your computer and one at the remote logger site. These modems

should respond to AT commands.

At least one standard modem cable. This cable connects a modem to your computer.

An IC-101 interface cable at the remote site.

If you are communicating with only one logger, you can use an IC-101 and a 9 to 25 pin

adapter, plus an MA-100(a null modem adapter).

For communicating with multiple SmartReader Plus loggers, you will need a YA-200 stereo Y

adapter / cable or YA-201 for each additional logger.
