What are the details and descriptions of the settings in the U+4?

Answer

Card Speed:

Select needed Baud rate(in the range from 1200 to 115200 bps) from the list. You would need to select the baud rate in accordance to the devices that you are communicating with i.e. the baud rate slected here and that of your device needs to be the same.

Filter:

Select what kind and format of packets you want receive:

-"All" - to receive all packets (including all types of MS/TP frames and error notifications). This option is generally chosen when using the U+4 hardware with a sniffer program like the BAS-o-Matic.

-"All BACnet data" - to receive all MS/TP frames transporting BACnet NPDU. This option is generally chosen when using the U+4 hardware with a sniffer program like the BAS-o-Matic.

-"Directed BACnet data" - to receive MS/TP frames with BACnet NPDU, destined only to our Node Address and Broadcasts.

-"Directed BACnet NPDU only" - to receive only directed or Broadcast NPDU. (accepted by any BACstac version). MS/TP information is absent.

Node Address:

Set address of this node in the range [0-254]. IMPORTANT Note: Master node must be in the range [0-Max_master]. Be careful to ensure that no two devices have the same Address.

Higher address can be set for monitor mode only (to track some slave node activity).

Node Type:

Select "Monitor" or "Master Node" based on what you would like to do.

Master Mode takes part in token passing and is needed for the BACstac. You would select the Master mode only if you are using the fieldbus interface as a BACnet client. In this mode, you would be able to completely discover the MS/TP network by using a BACnet client like the Cimetrics BACnet Explorer.

The "Monitor" mode can be used for Bas-o-matic only. This mode would be used if you are using the fieldbus interface purely for sniffing purposes only i.e. with programs like the BAS-o-Matic.

Max_info_frames[1-10]:

Max number of frames the node may sent before it must pass the token.

Max_master[1-127]:

Highest allowable address for master nodes.
