9.3.7
Output Pulses
Use the Output_Pulse X Y commands to set digital output states to
requested state for a specified time. Note that all example control messages in
this chapter use the "term123" identifier string and the password property is
set off (see Table 12).
While the pulse is active, the pin state remains as requested and is locked. You
can cancel the pulse with the Output_Pulse_Cancel command described in
Chapter 9.3.8. After the requested time has passed, the output state is returned
to the opposite value of that requested. The final state of the output is
independent of the initial state of the output.
The behavior of the output pins when the Output_pulse X command is used
is depicted in Figure 9.
