APPENDIX F. MEMS SENSOR TO MULTIPLEXER WIRING

Up to sixteen Uniaxial MEMS sensors are connected to the Canary six-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 clamp connections. A sample Uniaxial MEMS connection
is as follows for terminal block #1

Up to eight Biaxial MEMS sensors are connected to each Canary six-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 clamp connections. A sample biaxial MEMS connection
is as follows for terminal blocks #1 and #2:
