Connection
Web Interface
Description
After uploading and installing a newer firmware version, with some browsers you
may see the ‘Return to web page’ button grayed out and not accessible. This
only occurred with earlier versions of the Chrome browser. If this behavior is
still evident, upgrade your browser to the latest Chrome release.
The Unity card would not report that its RS485 MSTP Node ID conflicts with another
device on the bus when two cards with the same Node ID were installed on the same
device. One card would fail to connect to the managed device. Now a "Duplicate
BACnet MS/TP Node ID" alarm is activated when there are duplicate nodes on the bus.
The card in alarm will recover when the duplicate node is removed from the bus. This
defect is fixed.
Improvements were made to resolve a number of issues with the web login and
authentication process.

E-mail/SMS
Modbus
Description
Issues with incorrect e-mail/SMS notifications have been fixed.
Changed the Unity card behavior, when missing Modbus register values from the device
are detected, to match the behavior of the L-cards (IS-485L and IS-IPBML) to preserve
BMS Interface compatibility.

4. Known Issues
===================================================================================
Component
Description
Device Settings
When temperature settings are made on some thermal devices, there may be
some ‘round-off’ error of one tenth of a degree between what was requested and
what the device shows after the change. This is a known limitation of some
thermal device firmware versions and will be corrected in future versions of the
device controller firmware.
When selecting the Reset Event(s) buttons on the Summary webpage for some
devices, the user will be guided through an extra login and confirmation
sequence before the Reset request is successful.
For sites with a slow DHCP server, a Unity card using DHCP may fail to establish
some 3rd party protocol connections from the card. We are planning a fix to
make the Unity card more forgiving in these environments. A work-around until
then would be to configure the Unity card to use a Static IP Address, or to contact
your network administrator to improve the response time of the DHCP server.
There are a few (6) minor data point mapping errors for some thermal
management equipment which will be corrected in the next maintenance release.
There are some minor data point mapping errors for PeX and NXL equipment
which will be corrected in the next maintenance release.
