BCD POLE output

BCD polarity output.

OFF: Positive
ON: Negative

BCD DIGIT output

BCD numeric output for each digit.
Negative logic (i.e., Turns ON (set to 1) when NPN
open connector output is ON).

Comparator waiting status (with "–" displayed for
each digit): All digits set to B (1011)
Overrange (with "F" displayed for each digit): All
digits turn ON (1111).

BCD INDICATE
OUT1/2 output

Present OUT number turns ON.

OFF : OUT1
ON : OUT2

BCD SELECT
OUT1/2 input

Select and input the OUT number to be output.

OFF (Open) : OUT1
ON (Short-circuited to COM2 terminal) : OUT2

STROBE output

Output in synchronization with determined BCD
output.
