The bboxMax option defines a bounding box that surrounds all of the data you wish to show in non-tiled maps, i.e., you have set the tilingScheme option to null. Users can pan the map once they reach bboxMax but cannot zoom out further.

This option is a JavaScript array consisting of four values which can be thought of as: minx, miny, maxx and maxy of the maximum map view you wish to allow in map units and in that order.

A bboxMax option must be set properly for shingled (dynamic) services since the value of the map's zoom is based on a ratio between the current bbox and bboxMax.

Setting a new bboxMax will refresh the map services and reset what zoom level 0 means.

If you set tilingScheme to null, you must explicitly set bboxMax.
