Additional Settings 

These are additional settings you may also want to set from the OWS, and may be commanded as 
necessary, but rarely are once they have been set (or the control loop has been tuned).

ONFIGURATION

 

While AI1 is typically configured from the Configuration Menu, by setting the Temperature Units 
setting (degrees C or F), additional inputs such as AI2 (and AI3 on the DNT-T221) are configured 
through the OWS. Once you have ensured that the input is correctly wired and the hardware jumper is 
appropriately set, use ORCAview to verify that the AI object is not in manual mode and the units are 
properly set for the sensor. An exception to this is if AI2 is used for VAV airflow – setting the 
application will configure AI2 accordingly.

It is possible to copy the configuration setup of one BACstat to another. It is a simple 1-2-3 procedure: 

1.

 

Configure one BACstat for the desired application with the settings you want. 

2.

 

Save the BACstat settings to a file on ORCAview (as described below, under 

Save As

). 

3.

 

Load this file into the other BACstats on the network, one at a time. 

This should replicate the same configuration (i.e., object values) from one BACstat to another, and 
provide you a backup copy of the configuration settings in a file. The BACstat that you are copying the 
configuration 

to

 must have its application set either to NONE or to the exact same application as the 

saved setup.

LICKS

 

By clicking the right-mouse button on the BACstat icon in the left pane of Navigator you gain access to 
a number of device commands. 

Command 

CLEAR DATABASE

: The clear database feature (YES or NO) resets the configuration settings to the 

default. The following are not cleared: Baud Rate, Device Address, DNA/LINKnet, MaxMaster and 
Max Info Frame.

OMMUNICATION 

C

ONTROL

: This allows an OWS user to enable or disable a remote device from 

initiating and responding to all BACnet services, except for Device Communication Control services 
and Reinitialize Device services. It is primarily used for diagnostic purposes. Passwords are not 
supported (and need not be entered) for BACstats, and the time duration is infinite. 

R

ECONFIGURE

: If DNA is enabled on the BACstat, this will re-configure its address by deriving portions 

of it from other higher-level devices (for Area and System numbers). BACstat DNA addressing limited 
to 4194199. 

R

ESET

: This will reset the device, similar to powering it off and then back on again. 

Reload 

D

ESCRIPTORS

: This will reload the BACstat descriptors up into ORCAview OWS. This is particularly 

useful if for some reason the OWS is out-of-sync with what objects and object names the BACstat has.
