6.2. Epson G Series IMU Connector P2
The EIIB provides a 2x10 1 mm pitch socket connector P2 (Samtec CLM-1100-2-L-D) for directly
mounting the Epson G series IMU (M-G320, M-G354 or M-G364). There are two diagonal mounting
holes to secure the IMU to the EIIB. The recommended fastening hardware for these mounting holes
are SEMS M2-14 stainless steel screw and M2 stainless steel hex nut or equivalent.
The P2 connector silk screen and mounting holes provides a guide as to the correction mounting
orientation of the Epson IMU.
NOTE: Take precaution to ensure the supported Epson IMU is mounted correctly on P2, or else it may
cause permanent damage to the IMU, EIIB, or OEM7 Development Kit.
NOTE: If using Epson G series IMU on P2, do not mount an Epson V series IMU on P3.
