Trend Iqx Outstation Configuration - Toshiba Black Pear Installation And User Manual

8.2 Trend IQx Outstation Configuration

3 sensors (1 currently unused), 2 switches and 4 knobs are required to store all the
parameters for a single unit.
The table below shows how to calculate the number of each object required :

The Black Pear can be configured to enable only those objects of interest to the user,
therefore reducing the memory overhead required in the IQ outstation. Any objects
enabled in the Black Pear which aren't defined in the Trend outstation will simply be
ignored during the polling sequence.
Note that this does not change the sensor, switch and knob numbers associated with each
HVAC parameter.
If a sensor has been added to the sequence table then its 'Value'
output must be connected to its 'Source Value' input, otherwise it will
