The following illustration shows the module mounting into the receptacle on the RS-232 interface
board.
Century Interconnect and Samtec manufacture the 2 x 10 pin 2 mm spacing receptacles on Digi
development boards. Several other manufacturers provide comparable mounting solutions; we
currently use the following receptacles:
n
Through-hole single-row receptacles: Samtec part number: MMS-110-01-L-SV (or equivalent)
n
Surface-mount double-row receptacles: Century Interconnect part number: CPRMSL20-D-0-1
(or equivalent)
n
Surface-mount single-row receptacles: Samtec part number: SMM-110-02-SM-S
Note We recommend that you print an outline of the module on the board to indicate the
correct orientation for mounting the module.
