Abstract: A mounting structure for an analog converter box includes a mounting block having a base portion, a block first side wall extending from the base portion, an end wall intersecting the base portion and the block first side wall, and a block first front wall extending from the end wall and the block first side wall so as to overhang a portion of the base portion. The base portion, the block first side wall, the end wall and the block first front wall combine to define a block first pocket structured to receive a portion of the converter box therein. The converter box can be secured to a mounting surface in either of two, orthogonally-related orientations, for the convenience of a user and/or to facilitate testing operations.
