APPENDIX F –8032 MULTIPLEXER Manual

The following Appendix includes excerpts from the Model 8032 Multiplexer manual that apply

to the Micro-800. A complete version of the Model 8032 Multiplexer Manual can be found at

WWW.GEOKON.COM.

THEORY OF OPERATION

The Model 8032 Multiplexer expands the number of channels that can be read by the

MICRO-800 Datalogger or MICRO-1000 Datalogger. Channel switching is accomplished

by mechanical relays mounted on the underside of the circuit board and the transducer

connections are accomplished by friction locking spring-loaded terminals mounted on the

top side of the circuit board.

Two switching configurations are supported, 16 channels of 4 conductors or 32 channels

of 2 conductors. For the 8032-C, these configurations are set by a DipSwitch on the top

side of the circuit board. A second DipSwitch selects whether the 8032-C is being used

with a datalogger or GK-403 Readout Box

To protect against lightning or EMI/RFI induced transients, each channel is protected by

an integrated lightning protection system, incorporating 230V tripolar plasma surge

arrestors, 150V bipolar plasma surge arrestors, 10uH inductors and 16V transient voltage

protection diodes. See Appendix A for complete specifications on these components.
