APPENDIX F – MEMS SENSOR TO MULTIPLEXER WIRING
Up to sixteen (16) Uniaxial MEMS sensors are connected to the Canary 6 wire
Multiplexer through the weather tight strain relief fittings mounted to the Datalogger
enclosure; with the final connection made to the terminal blocks mounted on the
Multiplexer. Each terminal block, or Multiplexer channel, consists of seven (7) clamp
connections. A sample Uniaxial MEMS connection is as follows for terminal block #1

Up to eight (8) Biaxial MEMS sensors are connected to each Canary 6 wire Multiplexer
through the weather tight strain relief fittings mounted to the Datalogger enclosure; with
the final connection made to the terminal blocks mounted on the Multiplexer. Each
terminal block, or Multiplexer channel, consists of seven (7) clamp connections. A
sample biaxial MEMS connection is as follows for terminal blocks #1 and #2:
