Example: Assume we want a high limit, normal (reading), active on channel one; then,
YY = 01 OR’ed 08 = 09 HEX (NOTE: unlike most serial command parameters, this
is not ASCII).
REMOTE INPUTS:
Seven logic level, active-low, remote inputs are located on the rear of the unit for inter-
facing to programmable logic controllers etc.. The remote inputs can be used to dupli-
cate many of the front panel switch functions of the unit. A brief description of each
input follows below:
NORMAL MODE (remote input #1) --sets the display mode to reading only.
DATA REQUEST (remote input #2) --requests a serial transmission of the
display reading
RESET P/R (remote input #3) --resets the peak and runout readings
DATA HOLD (remote input #4) --A/D samples are ignored while this
input is active
RUNOUT MODE (remote input #5) --sets the display mode to runout
PEAK MODE (remote input #6) --sets the display mode to peak
CAPTURE TARE (remote input #7) --sets the tare value to the current
display reading
All remote inputs must be active for a minimum of 50mS (with the exception of DATA
HOLD which only needs to be held active a minimum of 1mS for detection).
