The remaining 4 recipients can receive SMS messages if any of the parameters are in an alarm
state. To receive the SMS messages for every number should be enabled with the checkbox
“Alarm Notification”. These 4 recipients can also ask by SMS for parameter state/value .
Activating checkbox “ Superuser rights” gives special rights to 4 users. Users can send all SMS
commands as the “M aster ” , except for commands to create new users and change the “M aster ” .
By pressing the “ S end test SMS” button all SMS recipients will receive a test SMS.
All commands, their syntax, and answers are described in “Setup via SMS”.
SMS is not a reliable communication and it is not recommended as a monitoring technology.
7.2.2. 1-Wire sensors setup
Detection of connected 1-Wire sensors is made either after power on or by the button “Scan”.
All found sensors are shown in ascending order refer to their unique ID number.
It is possible to lock a 1-Wire sensor in a specific position. To do this all sensors should be
added one by one. After every addition, a new scan should be made and a newly found sensor
should be locked in its
position
. If all sensors are locked, removing one “in the middle” will not
change the positions of other sensors after reset. This option is very useful when TCG120-4 is
used as a part of а monitoring and control s ystem managed by HTTP API commands.
7.2.3. Input/Output
7.2.3.1. Sensors
For every sensor, a description, up to 15 symbols can be set. These descriptions will appear in
the monitoring page, conditions page, XML/JSON data, SMS, and e-mail alerts.
For some sensors , fields “Unit”, “Multiplier” and “Offset” are available to convert the raw
values into meaningful units. The scaled value is calculated by:
SV[Un] = RV * MU + OF
Where:
SV
– scaled (displayed) value;
Un – unit;
RV – raw value from the sensor;
MU – multiplier;
OF – offset.
