
Always try to minimize BACnet messages to the VWG to the minimum. Care must be taken to insure that
the rate on incoming read or writes BACnet messages does not exceed the throughput of the wireless
ZigBee network. On an MS-TP VWG, please also remember that you are limited by the maximum
throughput of MS-TP at the selected and used Baud Rate. Updating 800 objects at the front-end system
over MS-TP will take a certain amount of time if you use lower Baud Rates like 9600 or 19200 KBps.
 If the configuration tool is opened on the VWG at the same time as the VWG is in operation with a fully
loaded database, expect both the tool and VWG to react with a small delay. Once all modifications,
servicing or configuration to the VWG is done, the tool should be closed to allow all resources of the VWG
to be used by the VWG wireless gateway application only. In all cases, Viconics recommends the tool be
closed when not used.
