Call-Back Configuration for the CR800/CR1000 – MultiLogger Application Note #19 – Page 3 of 12

Modem Call-Back

There are 3 different Modem call-back options supported in MultiLogger:

• COM220 Modem Call-Back – A Campbell COM220 with default settings, connected to CSI I/O

port.

• CSI I/O Modem Call-Back – A generic modem connected (with appropriate RS-232 interface

such as the SC32B or SC932) connected to the CSI I/O port.

• RS-232 Modem Call-Back – A generic modem connected to the RS-232 port.

Other devices and configurations may be supported for call-back, contact Canary Systems for assistance

with your application.

A schematic depiction is shown below for the COM220 Modem Call-Back option utilizing the Campbell

COM220. The architecture is similar for other modems.

The diagram illustrates a datalogger connected to a COM220 (using the CSI I/O port) connected to local

POTS, then a computer with phone modem and similar POTS connection. The computer is running

MultiLogger to accept the call-back events through the installed phone modem. Data are collected by

MultiLogger and optionally imported into the MultiLoggerDB database where alarm actions or other

notification can be initiated.

There are 3 steps to the MultiLogger configuration. The first requires configuration of the Alarm Action to

allow the CR800 or CR1000 to initiate call-back events.

Select the Program tab of

the Logger form to access

the Alarm Action drop-

down. Select the

appropriate option, in this

case COM220 Modem

Call-Back.

Note: These options

were included beginning

with MultiLogger version

4.3.4. Upgrades to the

current version are

available from the

Support area of our

website.
