For the 8032C, these configurations are set by a Dipswitch on the top side of the circuit board. A
second Dipswitch selects whether the 8032C is being used with a Datalogger or GK-403 Readout
Box.
Position one the DIP switch SW1 is used for switching between 16 and 32-channel operation.
Switch 1 ON = 32-channel; Switch 1 OFF = 16-channel. In Figure 29, 32-channel mode is
chosen:

The DIP switch SW2 is used for switching between a GK-403 or Datalogger application.
“DATALOGGER” is the default SW2 position, as shown in Figure 30.

F.2 MICRO-6000 Mode of Operation
The MICRO-6000 (which utilizes a CR6 controller, manufactured by Campbell Scientific, Inc.
of Logan, Utah) mode of operation uses two control lines to operate the multiplexer. The RESET
line enables the multiplexer and activates the Micro-6000 mode of clocking. Pulses received on
the CLOCK line sequentially increment the channels while the RESET line is held high. See the
timing diagram below.
The CLOCK line sequentially advances the channels beginning with channel 1. Note the timing
diagrams below for 16 and 32-channel switching, respectively.
