tsplink.trigger[N].mode
Function
The trigger operation and detection mode.
Usage
mode = tsplink.trigger[N].mode
tsplink.trigger[N].mode = mode
N
trig_mode
mode
Choose one the following values for mode:
0 or tsplink.TRIG_BYPASS
1 or tsplink.TRIG_FALLING
2 or tsplink.TRIG_RISING
3 or tsplink.TRIG_EITHER
4 or tsplink.TRIG_SYNCHRONOUSA
5 or tsplink.TRIG_SYNCHRONOUS Detects the falling edge input triggers and
6 or tsplink.TRIG_SYNCHRONOUSM
7 or tsplink.TRIG_RISINGA
8 or tsplink.TRIG_RISINGM
Remarks • You can express the mode as a number (0 through 8) or you can use one of the
pre-defined constants (see "Usage").
• The custom variable mode stores the trigger mode as a numeric value when the attribute
is read.
• The default trigger mode for a line is tsplink.TRIG_BYPASS.
• To control the line state, use the tsplink.TRIG_BYPASS mode with the
tsplink.writebit and the tsplink.writeport commands.
• (Firmware version prior to 1.4.0 only) Use the tsplink.TRIG_SYNCHRONOUS mode for
backward firmware compatibility.
• (Firmware version 1.4.0 and higher) Use tsplink.TRIG_SYNCHRONOUSA or
tsplink.TRIG_SYNCHRONOUSM modes.
• (Firmware version prior to 1.4.0 only) Use the tsplink.TRIG_RISING mode for
backward compatibility.
• (Firmware version 1.4.0 and higher) Use tsplink.TRIG_RISINGA or
tsplink.TRIG_RISINGM modes.

Example -- Sets the trigger mode for the synchronization line 3: tsplink.TRIG_RISINGM
tsplink.trigger [3] = 8
2600S-901-01 Rev. C / January 2008
Replace N with the number of the synchronization line: 1-3
The number of the trigger line.
The active trigger mode.
Selects the current trigger mode.
Allows direct control of the line.
Detects falling edge input triggers.
Asserts TTL-low pulse as an output trigger.
If the programmed state of the line is high, the
tsplink.TRIG_RISING mode behaves similar to
tsplink.TRIG_RISINGA.
If the programmed state of the line is low, the
tsplink.TRIG_RISING mode behaves similar to
tsplink.TRIG_RISINGM.
Detects rising or falling edge triggers.
Asserts a TTL-low trigger pulse.
Detects the falling edge input triggers and
automatically latches and drives the trigger
line low.
Asserting the output trigger releases the latched
line.
automatically latches and drives the trigger
line low.
Asserts a TTL-low pulse as an output trigger.
Detects rising edge triggers as an input.
Asserts a low TTL-low pulse for output.
Detects Rising Edge triggers as an input.
Asserts a low TTL-low pulse as an output.
Edge detection as an input is not available.
Generates a TTL-high pulse as an output trigger.
