7 I/O FUNCTION
No. Name I/O
Functional description
25 +OV OUT To be output if the measured value
exceeds the measurement range.
26 NOM OUT "H" at an anomaly
27 EXTEND OUT L: Execution of an RS-232C command,
which was activated by a HOLD input, is
being performed.
H: Execution of an RS-232C command,
which was activated by an HOLD input,
has been completed.
Purpose: Monitoring the RS data communi-
cation condition at the I/O port.
28 READY OUT "L" if the output data has been accepted.
29 START OUT "L" if only CEL1 data has been output.
30 NORMAL OUT "H" at an anomaly
31 P.SET IN Presets the specified CELs.
32 OUTCEL IN Sets the output CEL/calculation
33 SET1 IN method specified by SET1 through SET3
34 SET2 IN if the ON signal of OUTCEL was input.
35 SET3 IN In the NORMAL/High-speed mode:
CEL designation.
In the calculation mode:
Specification of calculation method.
36 HOLDINThe display value is held during the input.
The error is cleared at the rise of this signal.
Only EV-16Z re-detects the origin if the pa-
rameter No.42 is set to 1.
*: Outputs of No.3 through No.26 can be logically inverted
by the I/O output logic parameter.
**: Inputs of No.31 through No.36 are valid at "L".
4) Designating CELs to be output
For the detailed procedure, refer to section 7.7.5 Designating
CELs to be output/Specifying the calculation method.
SET3 SET2 SET1
Operation
000Outputs the data of all CELs as time-
division segment data (power-on
default)
001Segment output of CEL1 data
010Segment output of CEL2 data
011Segment output of CEL3 data
100Segment output of CEL4 data
101Segment output of CEL5 data
110Segment output of CEL6 data
111Specification prohibited.
