A.1.1 Headers
The RCM2000 uses headers at J1, J2, and J3 for physical connection to other boards. J1
and J2 are 2 × 20 SMT headers with a 2 mm pin spacing. J3 is a 2 × 5 header with a 2 mm
pin spacing.
Figure A-3 shows the layout of another board for the RCM2000 to be plugged in to. These
reference design values are relative to the mounting hole or to the header connectors.

NOTE: Two holes were added near the top of the RCM2000 above headers J1 and J2
starting with RCM2000 versions marked 175-0201 on the bottom side. These holes
facilitate factory testing and must not be used for mounting or attaching other hardware.
