LT20A / LT30 Series
9-5. Output
To output measured data from the RS-232C choose one of
the following four methods.
1. Input to the RS-TRG terminal
qq
qq
q
Initial setting:
(set at time of shipping)
This mode is for inputting mechanical contact outputs
(such as relay and switch outputs). Data is output
20 ms after an “L” level signal has been received.
2. Input to the RS-TRG terminal
ww
ww
w
Initial setting:
This mode is for inputting electronic contact outputs
(such as transistor outputs).
However, there must be no chattering in the input
signal. Data is output after an “L” level signal has been
received.
3. Output at set interval
Initial setting:
Eight intervals available, 0.2/0.5/1.0/5.0/10/30/60 and
300 s.
∗ This interval is set with the initial settings.
(See “5-1-3. RS-232C model”.)
4. Commands
Data is output by input ASCII code commands. For
more details see section 9-6.
Commands are received even in the output method 1,
2 and 3 modes.
• Holding display and output.
While the RS-TRG signal is “L” (ON), the display and
output (RS-232C data and I/O connector Go/No Go)
are held. However, when the initial settings of pins w
and r of the I/O connector (common) are changed
from
which was set at the time of shipping to
, the hold function for the display and I/O
connector Go/No Go output is enabled for the inputs
of pins w and r of the I/O connector (common), and
the RS-TRG input is canceled.
