4 THRESHOLD field • UPSTROKE/DOWNSTROKE knobs These specify the level that will be the threshold for outputting a trigger signal. A trigger signal will be output when the fader exceeds the UPSTROKE level, or when the fader falls below the DOWNSTROKE level. You can use the [TOUCH AND TURN] knob to operate these parameters. NOTE • The THRESHOLD values specified by the UPSTROKE/DOWNSTROKE knobs are common to all GPI OUT ports. However, you can individually choose the channel (fader) for each GPI OUT port. • Only the UPSTROKE value will be valid if MODE is set to FADER START, and only the DOWNSTROKE value will be valid if MODE is set to FADER STOP. If MODE is set to FADER TALLY, both the UPSTROKE and DOWNSTROKE values will be valid. 5 MODE field Here you can select the mode of fader operation that will be the trigger for signal output from the GPI OUT port. You can choose from the following fader modes. • NO ASSIGN Operating the fader of the selected channel will not cause a signal to be output. • FADER START A trigger signal 250 msec long will be output when the fader of the selected channel moves upward through the specified UPSTROKE level (-138.0 dB to 10.0 dB) from a point below it. • FADER STOP A trigger signal 250 msec long will be output when the fader of the selected channel reaches the specified DOWNSTROKE level (-∞ dB to 9.95 dB). • FADER TALLY A trigger signal will be output when the fader of the selected channel moves upward through the specified UPSTROKE level (-138.0 dB to 10.0 dB) from a point below it. This signal will be held until the fader reaches the specified DOWNSTROKE level (-∞ dB to 9.95 dB) or until that GPI OUT port receives a different trigger. Setup The following illustration shows how the signal that is output from the GPI PORT will change in each fader mode when a fader is operated. In this example, UPSTROKE in the THRESHOLD field is set to -60.00, and DOWNSTROKE is set to -∞. (This illustration shows the case in which is selected as the polarity of the GPI OUT port. If the polarity is , the polarity of the output signal will be reversed.) FADER START FADER STOP 250 msec 250 msec FADER TALLY NOTE At the high level, the output signal of the port will be open. If the receiving device requires high level, take it from the +5V power supply pin. However in this case, the amount of current is limited; for details, refer to "Control I/O specifications" on the QL Data List (End of Manual). 207 Reference Manual

THRESHOLD field
UPSTROKE/DOWNSTROKE knobs
These specify the level that will be the threshold for outputting a trigger signal. A trigger
signal will be output when the fader exceeds the UPSTROKE level, or when the fader falls
below the DOWNSTROKE level. You can use the [TOUCH AND TURN] knob to operate
these parameters.
NOTE
The THRESHOLD values specified by the UPSTROKE/DOWNSTROKE knobs are common to all
GPI OUT ports. However, you can individually choose the channel (fader) for each GPI OUT port.
Only the UPSTROKE value will be valid if MODE is set to FADER START, and only the
DOWNSTROKE value will be valid if MODE is set to FADER STOP. If MODE is set to FADER
TALLY, both the UPSTROKE and DOWNSTROKE values will be valid.

MODE field
Here you can select the mode of fader operation that will be the trigger for signal output
from the GPI OUT port. You can choose from the following fader modes.
NO ASSIGN
Operating the fader of the selected channel will not cause a signal to be output.
FADER START
A trigger signal 250 msec long will be output when the fader of the selected channel
moves upward through the specified UPSTROKE level (–138.0 dB to 10.0 dB) from a
point below it.
FADER STOP
A trigger signal 250 msec long will be output when the fader of the selected channel
reaches the specified DOWNSTROKE level (–∞ dB to 9.95 dB).
FADER TALLY
A trigger signal will be output when the fader of the selected channel moves upward
through the specified UPSTROKE level (–138.0 dB to 10.0 dB) from a point below it. This
signal will be held until the fader reaches the specified DOWNSTROKE level (–∞ dB to
9.95 dB) or until that GPI OUT port receives a different trigger.
The following illustration shows how the signal that is output from the GPI PORT will change
in each fader mode when a fader is operated. In this example, UPSTROKE in the
THRESHOLD field is set to –60.00, and DOWNSTROKE is set to –∞. (This illustration shows
the case in which
is selected as the polarity of the GPI OUT port. If the polarity is
, the
polarity of the output signal will be reversed.)
NOTE
At the high level, the output signal of the port will be open. If the receiving device requires high
level, take it from the +5V power supply pin. However in this case, the amount of current is limited;
for details, refer to “Control I/O specifications” on the QL Data List (End of Manual).
