Note: Computer control of Input Multiplexer and Output Sample and Hold is available when clock and test switches on the I/O box are in "Computer Input" and "Computer Output" positions, respectively. Manual operation of the Input Multiplexer and Output Sample and Hold is available when the same switches are "Clock Mode" and "Test Mode" respectively. In "Test Mode," output commands are derived from input channels 154 through 177 as noted in the current INPUT MULTIPLEXER STATUS. These channels are potentiometer readings from wither Joy Stick Console where Pot No. 1 is at the top and No. 10 is consecutively at bottom. See OUTPUT SAMPLE AND HOLD for Output Channel numbers.
