F.10 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:
