11、 its mounting, e.g. by means of a hinged door. The tachograph shall be circular in shape. 3.2 Dimensions Dimensions shall be as given in Figure 1 for the following items: a) body diameter, A; b) bezel diameter: 1) at mounting face, B 1 ; 2) at connector insertion face, B 2 ; c) body height above mou

12、nting face, C; d) bezel depth behind mounting face, including connectors and sealing device(s), D; e) hinge to top edge of body, E; f) trim panel clearance hold, F. 4 Electrical features 4.1 General Four connectors shall be fitted at the rear of the tachograph to provide the electrical interface. 4.

13、2 Connector pin assignments The functions assigned to pins shall be as given in Table 1. NOTE 1For connections without an assignment, i.e.unallocated pins, the preferred function is indicated. NOTE 2Each dash in Table 1 represents a switch selection point which is not occupied within the standard ba
