Eliminating BACnet segmentation

My device does not support segmentation. How do I disable segmentation within the TOP Server BACnet driver?

Segmentation occurs when the message length is greater than the maximum APDU length accepted by the devices. The message length can be reduced within the TOP Server by reducing the maximum number of items per request until the message is less than the APDU length.

A quick test to maximize TOP Server's update rate and eliminate the segmentation error is to reduce the maximum number of items within a message to 1 and slowly increase the number of items without reintroducing the segmentation error.
