The general RS485 connector (J1) is a 4-way terminal that provides 24V DC
power and RS485 differential signals to an external device that communicates
over RS485. This is for future functionality and is not yet implemented in
firmware or in the iNVent Configurator.
iNVent 2 has an SD card socket which is used to data-log the system
operation. 2 types of file are created on the SD card, a data-log of the system
status and an event log of notable events. This data can be used to analyse
the operation of an iNVent 2 system and associated products to provide case
study analysis of how the system is performing and allows Monodraught
The DIP switches on iNVent 2 provide some alternative functions /operational
modes.
At the moment these are only used for testing purposes.
They must all be set to “OFF” to ensure normal operation.
If the panel needs to be reset for some reason, instead of cycling the power,
the micro-controller can be reset using the reset button (S3).
The iNVent 2 panel has a built-in real-time clock which it uses for various
functions such as time-stamping data logs, calculating the current
season and providing out of hours closure of automated windows.
It uses a CR2032 battery in order to maintain the time and date when the
power is off to the panel. The battery should last 5 years with no power to the
panel. When the panel is powered, the battery is not used.
In order to satisfy different markets, iNVent 2 is provided with UTC, Coordinated
Universal Time, and Local Time. iNVent 2 will display the local time to the user
and for data logging purposes it saves the data in UTC in order to simplify the
analysis of the data, especially when daylight savings is enabled.
The BACnet module socket (A1) allows the optional BACnet module from
Cimetrics to be installed into the iNVent 2 panel in order to make system
status information available on a BACnet network, if desired by the customer.
Only BACnet/IP is supported and requires an Ethernet connection and a
static IP address. Please see the iNVent 2 - Optional BACnet module product
card for further information.
